03:08 AM lcnc-relay: <korbdallas> Bonjour à tous de la part d'un Frenchy.
03:08 AM lcnc-relay: <korbdallas> Je viens de découvrir votre projet et j'y ai relevé un petit problème, rien de grave mais c'est embêtant.
03:08 AM lcnc-relay: <korbdallas> En effet, dans tous les documents, il existe différentes langues (ça c'est cool 😎) mais ce qui est gênant c'est que les documents identifiés comme étant en français (_fr.pdf) sont en réalité en anglai
03:08 AM lcnc-relay: <korbdallas> s et non en français. En fait il n'y a que le titre et le nom du fichier qui sont en français, ceci est assez gênant et c'est vraiment dommage. Je pense que c'est une erreur mais ce serait super de co
03:08 AM lcnc-relay: <korbdallas> rriger cette erreur du coup.
03:08 AM lcnc-relay: <korbdallas> Merci beaucoup.

03:08 AM lcnc-relay: <korbdallas> Hello everyone from a Frenchy.
03:08 AM lcnc-relay: <korbdallas> I just discovered your project and I noticed a small problem, nothing serious but it's annoying.
03:08 AM lcnc-relay: <korbdallas> Indeed, in all the documents, there are different languages (that's cool 😎) but what is annoying is that the documents identified as being in French (_fr.pdf) are actually in English and not in Fre
03:08 AM lcnc-relay: <korbdallas> nch . In fact, only the title and the name of the file are in French, this is quite annoying and it's a real shame. I think this is an error but it would be great to correct this error at once.
03:08 AM lcnc-relay: <korbdallas> Thank you so much.
04:12 AM Tom_L: morning
04:12 AM Tom_L: cold is back: 7°F High 19°F
04:59 AM JT-Cave: morning
05:01 AM JT-Cave: 28°F Partly Sunny and Blustery then Sunny High: 24°F
05:02 AM JT-Cave: going to be a cold weekend here
08:39 AM XXCoder: you guys know whats going on with french language issue earlier?
08:39 AM Tom_L: no, i saw that though
09:59 AM Roguish: cool, and still dry, but the rain is moving in...
10:00 AM Roguish: Poplar Bluff is still pretty cold.
10:01 AM Roguish: Eugene is boardering on freezing.
10:01 AM Roguish: Kansas look pretty fricking cold...
10:08 AM Tom_L: 8°F
10:09 AM Roguish: Tom_L, where are you in Kansas?
10:09 AM Tom_L: Wichita

10:50 AM Unterhausen: No wonder all the docs started building, if they are in English now :)
10:50 AM Unterhausen: Wasn't there a French speaker working on the docs?
10:52 AM Unterhausen: I can read french pretty well, writing and speaking are a different matter entirely
11:06 AM lcnc-relay: <landlord101> Hello
11:06 AM roycroft: excellent
11:06 AM roycroft: for the first time in a week my network monitoring system shows no alarms
11:07 AM roycroft: as well, there is no sign of ice/slush this morning - it's finally all melted away
11:08 AM CloudEvil: :)
11:09 AM lcnc-relay: <landlord101> Hello
11:09 AM lcnc-relay: <landlord101> how much success would I have with PCI parallel port card and BOB and a latest PC i3/i5 6/7th gen, considering wanna do some basic demonstrations on a lathe, nothing too intensive
11:09 AM lcnc-relay: <landlord101> i dont have access to NVEM or Mesa boards as of now
11:09 AM lcnc-relay: <landlord101> * i dont have access to NVEM or Mesa boards as of now, due to import and customs issue
11:09 AM Unterhausen: it all depends on the latency of the system. It's possible you can turn off some of the energy saving and get better latency
11:10 AM Unterhausen: but some computers have a bios that just don't work that well with lcnc
11:10 AM Unterhausen: also, there is an RTAI version on the website which will probably work best with your system
11:10 AM Unterhausen: One final problem is that sometimes parports aren't properly discovered
11:11 AM roycroft: you really need to run a latency test on your target computer and see what the numbers are - the test comes with the lcnc distribution
11:14 AM lcnc-relay: <landlord101> 35000ns latency
11:15 AM Unterhausen: is that with rt-preempt or rtai?
11:15 AM Unterhausen: you might be able to get that to work
11:15 AM lcnc-relay: <landlord101> pree
11:15 AM lcnc-relay: <landlord101> okay
11:16 AM lcnc-relay: <landlord101> rtai link?
11:18 AM Unterhausen: okay, I thought there was an iso, but it requires some work, as alluded to here https://linuxcnc.org/downloads/
11:22 AM Unterhausen: tbh, I would just set things up with preempt and then if you have unexpected real time delays, do the switch
12:20 PM roycroft: my steel balls are allegedly out for delivery today, and my board retreat for this coming weekend has been postponed, so i may be able to finish my book press this weekend
12:21 PM roycroft: and no, i did not order the silver balls from that maga store in virginia :)
12:24 PM Rab: roycroft, balls for the handle, like this? https://i.pinimg.com/originals/18/44/b4/1844b4772727bcd8587428e805ed42d1.jpg
12:25 PM roycroft: yes
12:25 PM Rab: Classy!
12:27 PM roycroft: i made my press out of wood, with an acme vise screw
12:27 PM roycroft: but the design is similar to that picture
12:27 PM Rab: I've spent a lot of time in the book arts, including a stint in a hand bookbindery before doing IT. It's amazing how expensive the antique presses are now.
12:27 PM roycroft: yeah, they are
12:27 PM Rab: Nice crack in the base of the one in the pic. :(
12:27 PM roycroft: restored and in decent shape they bring in $1k or more
12:28 PM roycroft: i'm making this as a combination book press/veneer press
12:28 PM roycroft: my immediate use will be for the latter, but i do want to have a go at hand bookbinding
12:28 PM Rab: Are you restoring books, or making new ones?
12:29 PM roycroft: i'll probably start with new sketch books, as that's a common path to learning hand bookbinding
12:29 PM roycroft: and then move on to restoration
12:29 PM roycroft: this is the project for which i want to make the big wooden screws
12:31 PM Rab: Great! It's been 25 years since I've done that stuff seriously, but it's a medititative thing that's very different from most machining or other manufacturing. Everything has to be perfectly clean and handled with care for appearance's sake.
12:31 PM Rab: er, -it
12:34 PM roycroft: yes, i like the meticulous process part of it
12:36 PM roycroft: i've dabbled in leatherwork for some time, which is useful for the book cover work
12:36 PM roycroft: and i've taken an interest in paper marbling, which is useful for end papers and also for covers
12:37 PM roycroft: i don't expect i'll be able to make a living at bookbinding, but anticipate it will be a fun and engaging hobby that will incorporate some of the skills i use to make a living
12:38 PM roycroft: the book press i'm building is similar to this: https://www.youtube.com/watch?v=2vTo9hQS-T4
12:39 PM roycroft: and it's almost done - i just need to let the varnish oil finish curing, then wax it, and finish the handle construction
12:40 PM Rab: I know fine bookbinders who successfully operate(d) their own garage-scale shops, but the market doesn't really support larger scale enterprises.
12:41 PM roycroft: i think one can make a living at it if one finds the right market
12:42 PM roycroft: i have not bound a book from scratch, but i anticipate it would take the better part of a day to hand bind a fairly simple book
12:42 PM roycroft: and maybe several days to do a really ornate one
12:42 PM roycroft: not many people are going to pay $1k+ to have a book bound
12:43 PM Rab: Leather and marbling are excellent crafts. Hot foil stamping is an associated technique that I did a lot of. People make their own paper, too.
12:43 PM roycroft: and not many books deserve that kind of binding
12:43 PM roycroft: i picked up a hot foil stamper a few years ago
12:43 PM roycroft: i don't have any type for it, but my plan is to cnc engrave stamps for it
12:45 PM * roycroft brings the conversation around to the topic of the channel, and this time does it in a natural way
12:45 PM Rab: We had a Ludlow typecasting machine for one-off typography. For production runs we would outsource zinc dies. I have considered doing CNC for stamping dies and letterpress cuts. Photoengraving is the more common method.
12:46 PM roycroft: when i was in high school and just out of high school i worked in various print shops
12:46 PM Rab: Cast type metal degrades quickly under heat and pressure. Zinc is acceptable, brass is basically permanent and easily acid-etched.
12:47 PM roycroft: mostly doing offset printing (with an ab dick 360, which was the typical small shop press at the time), but i did some letterpress work with slugs from a linotype, and even some signs with a manual press with wooden type blocks
12:48 PM Rab: Yeah, a lot of shops kept letterpress around for flyers and other limited-production business items for years after their high-volume work had gone to offset and phototypesetting.
12:49 PM roycroft: for the hot stamping machine i'm thinking aluminium for one-off jobs and brass for multiples
12:50 PM roycroft: but for right now, the press i'm building will be used as a veneer press
12:50 PM Rab: I have my father's letterpress studio in storage, we kids are slowly cataloging everything to sell it off (except for a small family collection). Letterpress stuff has also gotten expensive; in the 1980s you could show up at small-town newspapers with a trailer and haul equipment away, but now it lives on as a boutique fine-arts thing.
12:53 PM Rab: I'd look into the stronger alumninum alloys--2024? It'll be easier to machine, and hot stamping can take a bunch of tries to get a good impression dialed in. 6061 might just act like chewing gum.
12:56 PM Rab: roycroft, which wood are you using for the screw?
12:58 PM roycroft: for the book press i used a steel acme screw - pretty much identical to the one in that video i linked to (it's actually a screw for a face vise for a scandanavian style woodworking bench)
12:59 PM roycroft: for the vice i'll be using hard maple for the screws - they'll be 2-1/2" x 3tpi
01:00 PM roycroft: the vise jaws will be bigleaf maple, harvested from the country fair site
01:00 PM Rab: Will you turn or threadmill the wooden screws?
01:00 PM roycroft: i'll be turning them with a router
01:01 PM roycroft: for the male threads
01:01 PM roycroft: the female threads will be single point cut
01:02 PM roycroft: using a boring bar, so i can take multiple passes
01:02 PM roycroft: and after i bore the pilot holes, intend to soak the bores in mineral oil for a week or so before cutting the threads
01:03 PM * roycroft has plenty of scrap wood for testing the process
01:18 PM lcnc-relay: <JT (@jt-shop:matrix.org)> Yo
02:37 PM XXCoder: watching inheirance, man inside threads would be hard for me lol
02:39 PM Rab: I got a backwards threading bar which lets you thread with the spindle in reverse, you can watch the tool and threading goes away from the chuck.
02:40 PM XXCoder: how do you start at same spot?
02:41 PM Rab: Same way as forward threading. I had a relief cut at the end of the threaded part, so I parked the tool there and engaged the nut.
02:42 PM Rab: https://www.amazon.com/dp/B0C9GP3FVV/
02:43 PM XXCoder: interesting
02:43 PM XXCoder: using left with outwards makes regular threads?
02:44 PM Rab: Right, if everything's backwards then you still get regular RH threads.
02:44 PM XXCoder: thats cool
02:45 PM Rab: Unsure where I read that tip, but probably HSM or PM forum.
02:46 PM XXCoder: I did only very little manual machining, and none on lathe
02:50 PM Rab: Ahh, this is the one I actually ordered: https://www.amazon.com/dp/B08R7N3M8G
02:59 PM roycroft: i've even seen abom do reverse threading, and he really likes to show off how fast he is at disengaging the half nut when doing forward threading
03:00 PM roycroft: some operations are too scary even for him
03:15 PM Tom_L: language translations: https://hosted.weblate.org/projects/linuxcnc/linuxcnc-docs/
03:15 PM Tom_L: french is at 2%
03:17 PM Tom_L: korbdallas guess you're out of luck
03:19 PM JT-Shop: http://linuxcnc.org/docs/2.8/html/index_fr.html
03:19 PM JT-Shop: 2.8 is translated to french
03:20 PM lcnc-relay: <xxcoder> see tom comment above
03:20 PM XXCoder: (reply ping so guy can find it evenually)
03:37 PM andypugh: XXCoder: Inside threading is just as easy as outside if LinuxCNC is in charge
03:38 PM andypugh: I do left-hand threads backwards, though.
03:38 PM XXCoder: :)
03:42 PM JT-Shop: there was one ember left in the stove in the machine shop when we got home
03:49 PM Tom_L: how much change between 2.8 & 2.9 i wonder
03:49 PM Tom_L: and why does the chart indicate they started translation all over?
03:50 PM JT-Shop: you would have to ask the doc person
03:50 PM Tom_L: hey Doc!
03:50 PM JT-Shop: he's not here anymore
03:50 PM Tom_L: pere ?
03:50 PM Tom_L: he'd been working on it some too i think
03:50 PM JT-Shop: no clue lol
03:51 PM JT-Shop: have to look at the commits
03:52 PM Tom_L: how's JET coming along?
03:52 PM JT-Shop: we went to Ste. Genevieve for a funeral today
03:52 PM Tom_L: ahh the daughter's friend? iirc...
03:52 PM JT-Shop: I need to rename it :) but I'm working on a touch .qss file
03:53 PM JT-Shop: yup
03:53 PM JT-Shop: 30 years old and was walking down the sidewalk after bowling and just fell over
03:55 PM XXCoder: wow pretty random
04:00 PM Tom_L: roads clear?
04:00 PM JT-Shop: mostly clear
04:01 PM Tom_L: i noticed you'd added quite a few more boards recently
04:03 PM JT-Shop: well I enabled some older boards for mesaflash work only and split out the 5i25 and 6i25 as selections
04:06 PM * JT-Shop goes to start a fire in the other shop
04:08 PM pere: Tom_L: what is up?
04:08 PM Tom_L: wondered who has been working on the linuxcnc documents
04:08 PM Tom_L: a guy was looking for the french translation
04:09 PM Tom_L: 2.8 has it but 2.9 doesn't
04:09 PM Tom_L: specifically the pdf
04:12 PM Tom_L: looking at the weblate chart it seems they started over on it
04:12 PM Tom_L: https://hosted.weblate.org/projects/linuxcnc/linuxcnc-docs/
04:14 PM JT-Woodshop: 2.9 docs use a totally different system
04:15 PM Tom_L: JT-Woodshop, what file has the calc code?
04:17 PM JT-Woodshop: calc code for?
04:18 PM pere: no-one has taken the time required to bring the french translation up to date and in sync with the english source documents, so it is sadly not much translated yet.
04:18 PM pere: I do not know french, but would be happy to provide guidance if someone want to work on it.
04:20 PM roycroft: i has big steel balls
04:20 PM roycroft: they arrived today after all
04:21 PM XXCoder: congats youre an tough male now
04:21 PM roycroft: i did not get them from the maga mall
04:21 PM XXCoder: anyway cant wait to see your press completed!
04:21 PM roycroft: nice
04:21 PM roycroft: i ordered rough cast
04:22 PM roycroft: what i got are not polished, but they are smooth - the mill scale has been ground off
04:22 PM roycroft: that will save me a lot of cleaning up work
04:22 PM XXCoder: sounds like qualty cast company
04:22 PM XXCoder: how much did it cost?
04:23 PM roycroft: the balls were $26 for the pair, but there was a $36 shipping charge
04:23 PM XXCoder: probably because those is heavy
04:23 PM XXCoder: not too bad though
04:23 PM roycroft: i'm going to use jt's suggestion - i'm not going to try to tap them
04:24 PM roycroft: i took a 3/4" pipe coupler, turned the outside down smooth, and cut it in half
04:24 PM roycroft: i'll bore out openings in the balls and weld the half couplers in them
04:24 PM roycroft: that will be way easier than trying to tap them directly
04:24 PM JT-Shop: yup
04:24 PM roycroft: i already prepped the coupler
04:25 PM JT-Shop: black iron coupling?
04:25 PM roycroft: yes
04:25 PM XXCoder: interesting
04:26 PM roycroft: i was going to shoot the balls with bronze metallic spray paint, but they're almost smooth enough to gild
04:26 PM Unterhaus_ is now known as Unterhausen
04:26 PM roycroft: so maybe they'll get some gold leaf
04:27 PM JT-Shop: fancy
04:27 PM JT-Shop: my steam box swelled apart...
04:27 PM Unterhausen: pere is the update mostly formatting? Do we know what contents changed in the docs
04:27 PM roycroft: i paid way more than i wanted to for these, but they are exactly what i wanted
04:27 PM roycroft: did you leave too much water in it?
04:28 PM * roycroft has to figure out how to fixture the balls on the mill table now
04:28 PM Loetmichel: roycroft: may be a case for electrolytic gold?
04:28 PM JT-Shop: water is in the turkey fryer the wood just expanded on the inside and split open the glue joints
04:28 PM roycroft: gilding would be fine
04:28 PM XXCoder: isnt brass more traditional look
04:28 PM roycroft: and it's something i want to learn how to do anyway
04:28 PM XXCoder: not sure if it can be coated in brass for brass look or not
04:28 PM roycroft: a lot of the victorian era book presses are gilded
04:28 PM XXCoder: ahh ok
04:29 PM pere: Unterhausen: I do not understand the question. translations are done using PO files now, ensuring all language editions include the same text.
04:29 PM roycroft: but if i want brass i'll just use some metallic brass spray paint
04:29 PM JT-Shop: https://thepatriotwoodworker.com/forums/topic/39783-steam-bending/page/2/#comment-328205
04:29 PM roycroft: i'll worry about the finish later
04:29 PM roycroft: for now i just want to get the handle made
04:29 PM pere: Unterhausen: if you want to help with french translation, update the PO files using the Weblate editor.
04:29 PM Unterhausen: I just wonder what has to be done to get the french translation closer to completion
04:29 PM Unterhausen: what does PO stand for?
04:30 PM JT-Shop: find someone that knows french and english and has the time to work on it
04:30 PM pere: Unterhausen: no idea what PO stands for, but it is the file format originally used by gettext to handle translations. now it is used in a lot of different systems.
04:30 PM Unterhausen: I think I can translate most of it
04:31 PM roycroft: jt: just glue it back together and then put a band clamp around it before you use it again
04:31 PM pere: <URL: https://hosted.weblate.org/projects/linuxcnc/-/fr/ > is the place to start,
04:31 PM Unterhausen: if I have the previous translation and some idea what changes are needed
04:31 PM JT-Shop: Unterhausen, Francis stopped working on the french docs a long time ago
04:31 PM Unterhausen: there were a lot of changes in lcnc since 2.8
04:33 PM pere: The documentation part is in <URL: https://hosted.weblate.org/projects/linuxcnc/linuxcnc-docs/fr/ >. I recommend starting on the "Failed check" entries.
04:34 PM Unterhausen: okay, thanks
04:34 PM JT-Shop: Unterhausen, the last time Francis did any work on the french docs was 13 years ago
04:34 PM pere: registered users can update the translation directly, while unregistered users can only suggest translations.
04:35 PM pere: some registered user can then review suggestions and accept or reject them.
04:36 PM pere: Unterhausen: are you registered with weblate? did you set up your set of primary and secondary languages?
04:36 PM Unterhausen: I have never really thought about doing this before, so no
04:36 PM JT-Shop: https://thepatriotwoodworker.com/forums/topic/39783-steam-bending/page/2/#comment-328205
04:37 PM JT-Shop: Tom_L,
04:38 PM Unterhausen: is the translation I'm looking at on the weblate site done by a person, or machine?
04:38 PM pere: Unterhausen: hard to tell, only you know what you are looking at.
04:39 PM Unterhausen: is some of the French on there a machine translation?
04:40 PM Unterhausen: reason I ask is that there are specialized words, like "spindle" where I have no idea if the French is the proper word
04:41 PM XXCoder: I wonder if partial transition, leaving uncertain words english, would work
04:41 PM XXCoder: in least till someone more expert voluneers
04:41 PM Unterhausen: need a French speaking machinist
04:41 PM XXCoder: most words arent specialized
04:42 PM JT-Shop: unless you speak french it's almost impossible to translate technical documents
04:42 PM Unterhausen: I know, I can read about 90% of it no problem
04:42 PM Unterhausen: or more, actually
04:42 PM JT-Shop: that's 90% more than me
04:42 PM XXCoder: thats what I meant, translate what you can
04:43 PM Unterhausen: I have to admit the formatting problems are stumping me right now, should be easy
04:44 PM pere: Unterhausen: I do not know the origin of the french draft texts or translations. there is a machine translation tool available in weblate, and someone might have used it. if you are unsure about a translation you have done, mark it with 'Needs editing' to flag that it need more work.
04:45 PM XXCoder: hopefully, if most of easy work was translated, someone native speaker would come in and fix some words and its nearly complete
04:45 PM lcnc-relay: <korbdallas> Good evening everyone, thank you for your various responses. So if I understood correctly, it would be the latest version which would not be up to date. So I'm out of luck. I think I have seen mess
04:45 PM lcnc-relay: <korbdallas> ages passing by asking if someone could do these translations, I would have offered to help you but not only do I not know the Weblate software at all but above all, it is my friend Google who allows
04:45 PM lcnc-relay: <korbdallas> me to you write and read in English so in terms of translation I think it is better to let someone much more comfortable with these 2 languages to translate the different documentation. 😉 😁 🤣 😂
04:45 PM pere: some of the strings marked 'needs editing' are derived from a mapping of the original french translation to the english source files, but it might be mistaken. some of the strings are gettext guesswork based on similarities to other strings. it all need to be proof read by someone who know the language.
04:46 PM Unterhausen: So I have an example, I think the french translation uses 1 space after a sentence and English uses 2
04:46 PM Unterhausen: https://hosted.weblate.org/translate/linuxcnc/linuxcnc-docs/fr/?checksum=096f60851eb1ced4&sort_by=-priority,position
04:46 PM Unterhausen: how do you fix that?
04:47 PM pere: Unterhausen: this is a misunderstanding. it is not consistent in english.
04:48 PM pere: If the words are correct, just remove the unneeded space and save the string.
04:48 PM pere: as far as I can tell, the french formatting is wrong with that one, ' should be `.
04:49 PM Unterhausen: I think it flagged the end of the sentences though, not the '
04:51 PM Unterhausen: I can google the error messages and see what the internet tells me
04:52 PM pere: note, as french is not in my list of primary or secondary languages in weblate, I do not see the error messages.
04:55 PM lcnc-relay: <unterhausen> funny, I can see them as n unregistered user
05:04 PM Unterhausen: so if something doesn't get translated, like code, I can just hit "clone to translation"?
05:04 PM pere: yeah, and remove the 'needs editing' flag.
05:07 PM lcnc-relay: <unterhausen> What interface are you using? Have you started using lcnc yet?
05:08 PM Unterhausen: bridge doesn't show you were replying to someone
05:09 PM XXCoder: old bridge was awesome that everyone was pingable from everyone else. but I dont think it will ever return
05:09 PM Unterhausen: I'm just learning the new one's shortcomings. It's possible I will be able to adapt
05:11 PM Unterhausen: The menus and such in lcnc guis have never been translated, correct? Going to complicate things a bit
05:11 PM Tom_L: JT-Shop, sry, i had to leave for a bit
05:11 PM JT-Shop: understand
05:11 PM Tom_L: i wanted to look at the scale calc code
05:11 PM JT-Shop: moment
05:12 PM JT-Shop: https://github.com/jethornton/mesact/blob/master/mesact/src/libmesact/utilities.py#L203
05:12 PM JT-Shop: https://github.com/jethornton/mesact/blob/master/mesact/src/libmesact/utilities.py#L248
05:12 PM Tom_L: put a ratchet strap around the steamer
05:14 PM JT-Shop: that doesn't sound very practical...
05:14 PM Tom_L: put some screws in
05:14 PM Tom_L: predrill the outer board then screw it together
05:15 PM JT-Shop: I was thinking of through bolting sides and bottom without any glue and allow them to expand without pulling apart
05:15 PM Tom_L: yeah
05:15 PM JT-Shop: kind of like you would do for a table top
05:15 PM JT-Shop: brb
05:15 PM Tom_L: yup
05:20 PM lcnc-relay: <korbdallas> For the moment I don't use anything, I came across your project by chance while browsing the internet and I wanted to know more. That's why I downloaded the documentation. Am curious.
05:21 PM JT-Shop: the 2.8 french docs should be close
05:28 PM * JT-Shop calls it a night
05:30 PM lcnc-relay: <korbdallas> Ok thank you I will look at this version. In any case, thank you all and good luck for the rest of your project.
05:30 PM XXCoder: hope you find it useful
05:35 PM * JT-Cave waits for the door to go down...
05:37 PM Loetmichel: JT-Cave: i hope the motor isnt fast an not that powerful. what i know from chickens: they are not the brightest bulbs on the tree... may have some decapitated ones if the door is too fast.
05:38 PM JT-Cave: Loetmichel, it's slow and on a string...
05:38 PM Loetmichel: ok. Just sayin' :)
05:39 PM JT-Cave: I have a well thought out automagic chicken door that can't harm a chicken and can't be opened by a predator should it get past the electric fence, the chain link fence and the auto targeting lasers
05:41 PM Tom_L: are the birds still winning though?
05:41 PM JT-Cave: they always win
05:43 PM Loetmichel: those sentry lasers sound interesting. how many joules per "shot"? :)
08:34 PM roycroft: so no gilding the steel balls
08:34 PM roycroft: i thought i had a good fixture - a pair of vee blocks and an extra clamp to squeeze everything together really tightly - but apparently not so
08:35 PM roycroft: the first one moved, got banged up by the end mill, which broke
08:35 PM roycroft: so it's bondo time, and i can make bondo look good but i won't be able to gild over it
08:35 PM roycroft: the balls are also drilled and tapped for 3/8" studs - no 3/4" pipe threads for those
08:35 PM Tom_L: shoulda got a spare ball
08:36 PM roycroft: yeah, i considered that
08:36 PM roycroft: i'm a good enough machinist to know this was a very scary operation, and that my fixture was a little on the sketchy side
08:37 PM roycroft: but obviously not good enough to prevent the thing from moving
08:37 PM Tom_L: i can usually dial a new part in with one spare
08:37 PM roycroft: anyway, i do have two balls with 3/8" tapped holes
08:37 PM Tom_L: so why use the pipe? get some hard 3/8" rod and use it
08:37 PM roycroft: and after bondo there will be no visible damage to the first one
08:37 PM roycroft: well i already have the pipe
08:38 PM Tom_L: or 1/2 and turn the end down and thread it
08:38 PM roycroft: but yea, some 3/8" grade 5 allthread would probably be perfect
08:38 PM Tom_L: my local guy sells drill rods in 3' lengths oil or water quenched
08:39 PM roycroft: although the tee that connects the handle to the acme screw is all ready to go, painted and everything, and it's set up for the 3/4" pipe
08:39 PM roycroft: but i could fix that
08:39 PM * roycroft has more paint
08:39 PM Tom_L: bushing
08:39 PM roycroft: it already has a busing
08:39 PM roycroft: it would need a different bushing
08:39 PM Tom_L: make one for a smaller rod
08:39 PM roycroft: and using a rod would actually be better
08:39 PM roycroft: i'm concerned that the wooden sleeves i'm going to turn to cover the pipe would be really thin and hard to make well
08:39 PM Tom_L: 3/8 rod with a 3" ball might look a little odd
08:40 PM roycroft: if i go from the pipe diameter (~1in) to 3/8" the sleeves would be a lot more solid
08:40 PM roycroft: i might even have enough 3/8" grade 5 allthread in stock
08:41 PM roycroft: since my weekend retreat got postponed, i just got two free days
08:42 PM roycroft: i don't mind spending one of them regrouping and redoing the handle part
08:42 PM Tom_L: i wonder if they roll the threads on all thread
08:42 PM Tom_L: i doubt they're cut
08:43 PM roycroft: they're probably rolled
08:43 PM Tom_L: roll threads are stronger anyway
08:43 PM roycroft: it's a lot faster and cheaper to do
08:43 PM roycroft: if i have any, it's grade 5, because that's what i always had to use in telecom offices
08:44 PM roycroft: it's more likely that i have 1/2"-20 or 5/8"-11 allthread than 3/8"-16 or 3/8"-24
08:45 PM roycroft: but any of that could work because, as you said, i could turn the ends down and thread them to 3/8"-16
08:45 PM Tom_L: your problem was holding the ball while machining/
08:45 PM Tom_L: ?
08:45 PM roycroft: yes
08:46 PM Tom_L: 2 2" pipes opposite each other in a deep vise jaw
08:46 PM roycroft: well, my real problem was not being experienced enough to know what i could get away with
08:46 PM roycroft: on the second ball i had to mill a flat like on the first one
08:46 PM Tom_L: short of course
08:46 PM roycroft: i used a 1/4" end mill for that, and took 0.010" passes
08:47 PM roycroft: it was very tedious, but it worked fine
08:47 PM roycroft: i tried a 5/8" end mill on the first one, and was taking 0.005" passes just fine
08:47 PM roycroft: until it wasn't fine
08:48 PM Tom_L: you found the limit
08:48 PM roycroft: i did
08:48 PM lcnc-relay: <big_kevin420> collet chuck?
08:48 PM Tom_L: the pipes would hold it
08:48 PM roycroft: and now i'm more experienced than i was
08:48 PM roycroft: i'm not sure how a collet chuck would hold a round ball securely
08:48 PM Tom_L: big_kevin, it's not holding the tool more than holding the part
08:48 PM Tom_L: it's a sphere
08:49 PM roycroft: and the balls are not perfectly round
08:49 PM Tom_L: mine aren't either
08:49 PM Tom_L: get 2 pipe couplers to hold them
08:49 PM Tom_L: then you don't have to make anything
08:50 PM roycroft: i don't have a vise big enough to hold that
08:50 PM Tom_L: need a fair size vise
08:50 PM roycroft: but the holes are drilled and tapped now
08:50 PM roycroft: all machining on the balls is done
08:50 PM roycroft: i just have to do some bondo work on the first one, and then they're ready for paint
08:51 PM roycroft: i was going to drill and tap for 1/2" studs, but by the time i got the 5/16" hole drilled i felt i had reached my limit before things went sketchy again
08:51 PM roycroft: and that happens to be the pilot size hole for a 3/8"-16 tap, so it was a good place to stop
08:52 PM roycroft: i had considered tack welding some flat pieces to the balls so i could fixture them better, but didn't feel like doing the grinding work after to clean them up
08:52 PM roycroft: that might have been less work than the bondo work i have ahead of me, but oh well
08:52 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/thread_mills/Mill_Holder10.jpg
08:53 PM roycroft: for this application, the bondo will be just fine
08:53 PM Tom_L: those were 3/4 13? i think
08:53 PM roycroft: 3/4" 10 probably
08:53 PM roycroft: unless you decided to do something weird
08:53 PM Tom_L: whatever the sherline spindle is
08:53 PM roycroft: 3/4" 10 or 3/4" 16
08:54 PM roycroft: those are the standard sizes
08:54 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/thread_mills/Mill_Holder_Steel1.jpg
08:54 PM Tom_L: i single pointed the side one as well
08:54 PM roycroft: maybe you weren't sure and split the difference :)
08:54 PM * roycroft heads off to make pizza
08:54 PM Tom_L: nice thing about single point is the lead in cut is very short
08:55 PM Tom_L: unlike a tap
08:55 PM roycroft: i like single point turning
08:55 PM roycroft: i've discovered, though, that i do not like machining big steel spheres
08:55 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/thread_mills/Thread_mill2.jpg
08:56 PM Tom_L: should cover anything i need to thread
08:57 PM Tom_L: you just need a better fixture
09:16 PM Tom_L: not what i was looking for but interesting anyway: https://www.youtube.com/watch?v=ZApe7FqVbZM&embeds_referring_euri=https%3A%2F%2Fhplapidary.com%2F&source_ve_path=OTY3MTQ&feature=emb_imp_woyt
09:22 PM roycroft: i need bigger machines, actually
09:22 PM roycroft: i was pushing beyond the reasonable limits of my machines
09:23 PM roycroft: a bigger vise would have helped a lot, but i can't reasonably put a bigger vise on my mill
09:23 PM XXCoder: bah! show a machine but dont show it being used
09:23 PM Tom_L: i would have made some rather tall softjaws and clamped it with pipe
09:23 PM Tom_L: the vise doesn't have to be tall
09:24 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/thread_mills/Boring_Mill_Holder.jpg
09:25 PM Tom_L: i make them tall so i can also reuse them for other projects just by milling them flat again
09:25 PM roycroft: but i came with a solution using my current machines, albeit a suboptimal one
09:26 PM roycroft: fortunately this application does not require high performance or accuracy - the end result will be just fine with what i'm doing now
09:26 PM Tom_L: most of mine is the same wa
09:26 PM Tom_L: way
09:30 PM Tom_L: XXCoder, the one i linked from did..
09:30 PM Tom_L: hmm
09:33 PM Tom_L: https://youtu.be/Sr6lnqxyK-s
09:33 PM Tom_L: XXCoder, ^^
09:34 PM XXCoder: looking
09:35 PM XXCoder: thats cool
09:36 PM XXCoder: I guess it requires initial sphereness before can be used there
09:37 PM Tom_L: https://www.youtube.com/watch?v=quwOc9gj45g
09:38 PM Tom_L: doesn't have to cost a million bux
09:38 PM Tom_L: those are pipe reducers
09:39 PM XXCoder: yeah. pretty cool
09:43 PM roycroft: i might just weld up the dings in the first ball
09:43 PM roycroft: if i do that then i can still gild if i want
09:46 PM Tom_L: i should think about making some more soft jaws
10:18 PM roycroft: if i were to start machining metal spheres on a regular basis, i'd probably make some vise jaws that are inversely spheriod, and line them with emory cloth or something like that
10:50 PM solarwind: Aw shit
10:50 PM solarwind: I over sharpened my 10mm drill and don't have my cutter grinder yet
10:50 PM solarwind: So can't do web thinning
10:54 PM solarwind: And the M12 drills are too weak for 10mm x 200mm deep holes in softwood
10:55 PM solarwind: Well not worth it. Not smaller than the dewalt 20V compact ones and less than half the power
10:56 PM Loetmichel: solarwind: try step drilling?
10:56 PM Loetmichel: aka: 4mm, then 8mm, then 10mm?
10:56 PM solarwind: Loetmichel yeah when you don't have a web thinning cutter grinder, you pretty much have to do that
10:57 PM Loetmichel: i used to do web thinning with a dremel cutting disc
10:57 PM solarwind: https://www.dewalt.com/product/dcd998w1/20v-max-xr-12-brushless-cordless-hammer-drilldriver-power-detect-kit DCB998 is a fucking MONSTER though
10:58 PM Loetmichel: you'll have to have a steady hand though
10:58 PM solarwind: torque test channel measured at > 1100W sustained output
10:58 PM solarwind: I got the same results
10:59 PM solarwind: Loetmichel yeah I was contemplating putting a grinding bit in the CNC router and then remembered it's not worth worrying about a $5 drill bit when it could get grinding dust all over the slide ways
10:59 PM solarwind: especially when my Cincinnati cutter grinder is going to be in the shop soon
