05:42 AM lanclanterns: ok, I still haven't solved my 7i84 detection problem. I'm going to use a 2nd 7i77 that I have laying around so I can keep moving
08:05 AM perry_j1987: morning
08:24 AM pink_vampire: morning
08:34 AM perry_j1987: looking at mini mills this morning :P

08:35 AM perry_j1987: something more affordable :P
08:35 AM pink_vampire: gregcnc: LOL!!!!!!!!
08:38 AM jdh: perry_j1987: where are youe
08:38 AM perry_j1987: us
08:39 AM jdh: that narrows it down. buy my g0704
08:39 AM gregcnc: that narrows it down to 3.8 million miles^2
08:39 AM pink_vampire: earth
08:44 AM perry_j1987: jdh sent you msg
09:02 AM JT-Shop: lanclanterns: the 7i84 should show up automatically if the cat6 cable is wired properly and power is supplied to the card and W1 and W2 are set to the left position
09:03 AM perry_j1987: r8 er20 tool holders if use torque wrench on the drawbar should get fairly repeatable?
09:48 AM Deejay: hi
10:10 AM CaptHindsight: fairly repeatable = ? +-0.2mm, +-0.05mm, +-1mm
10:12 AM jesseg: LOL
10:12 AM jesseg: I'm going with +-1mm
10:43 AM pink_vampire: I got height gauge!
10:43 AM pink_vampire: for free!!
10:43 AM pink_vampire: just 5", but it work very nice
10:44 AM pink_vampire: it came with small surface plate
11:02 AM skunkworks: https://www.youtube.com/watch?v=RXXl1vDjmTc&t
11:07 AM pink_vampire: nice
12:43 PM JT-Shop: wow I need to clean the plasma table off and cut a part...
12:43 PM Tom_L: 2 day job?
12:44 PM JT-Shop: lol 1/2 day
12:47 PM Tom_L: http://ruemohr.org/~ircjunk/projects/smelter/p1120481.jpg
12:47 PM Tom_L: needs a little more heat and maybe another vent
12:47 PM FinboySlick: skunkworks: You even got 90's steady-cam action.
12:49 PM FinboySlick: Always loved your mill though. It's such a beast.
12:54 PM CaptHindsight: I'm actually surprised that the block is that square to the bores
12:58 PM sync: why wouldn't it be that square
12:59 PM CaptHindsight: old factory parts were always off, why we "blueprinted" anything we needed to last or rev higher
01:00 PM CaptHindsight: " Local machine shops said that they couldn't bore any smaller than .060 over... We bored it .020 over."
01:01 PM sync: in my experience that is not really the case, at least the main alignment is pretty good
01:01 PM CaptHindsight: what you want me to actually align everything to within a few thou!!??
01:01 PM CaptHindsight: his video was from the early 90's so i was guessing a 60-70's engine
01:02 PM gregcnc: sync how many old american v8 blocks do you see over there?
01:03 PM skunkworks: FinboySlick: it hasn't gotten any better ;)
01:03 PM CaptHindsight: yes USA vs Euro engines in the 50's-80's did not compare
01:04 PM CaptHindsight: skunkworks: when we were in HS we only had access to Bridgeports
01:05 PM skunkworks: CaptHindsight: don't know the exact year - it is the 6.9 liter international harvister engine ford put in their pickups initially
01:05 PM skunkworks: early 80's
01:05 PM CaptHindsight: I pretty much lost track of everything after 1973
01:06 PM skunkworks: it was actully pretty square.. we were able to bore it .020 over...
01:06 PM skunkworks: (smallest over pistons we could buy)
01:06 PM CaptHindsight: were there shims under the front of the block?
01:07 PM skunkworks: heh - don't remember... I would have to ask dad if he remembers. Could have been...
01:07 PM pink_vampire: I need to make this part
01:07 PM skunkworks: I think we just trammed one side - then the other side worked..
01:07 PM skunkworks: 90 deg
01:07 PM pink_vampire: someone want to make it for me
01:08 PM FinboySlick: skunkworks: All the motion is hydrolics, right?
01:08 PM pink_vampire: https://i.imgur.com/dRiAkFT.png
01:08 PM skunkworks: FinboySlick: yes - in that video..
01:09 PM FinboySlick: skunkworks: OK, you modified it to use servos laster, as I vaguely recall.
01:09 PM Tom_L: your video skilz have improved :)
01:10 PM CaptHindsight: Tom_L: must have been his dad or someone else since he is in the frames :)
01:10 PM FinboySlick: CaptHindsight: Selfie-broomstick.
01:10 PM FinboySlick: To hold them hefty 90s cameras.
01:12 PM CaptHindsight: I saw a VHS cam at a Good Will the other day, was tempted to buy it
01:14 PM CaptHindsight: was even bigger than this one https://upload.wikimedia.org/wikipedia/commons/thumb/5/50/Hitachi_VM-600E_VHS_Camcorder.jpg/800px-Hitachi_VM-600E_VHS_Camcorder.jpg
01:15 PM skunkworks: FinboySlick: yes - servos and full 3 axis. (was 2.5)
01:16 PM PL7icnc: Good evening from a Sunny day in Germany
01:16 PM PL7icnc: is RodV from the Forum present here
01:17 PM skunkworks: This was a super8 vhs? so not super huge
01:18 PM PL7icnc: skunkworks, if you do digitalisation it can bee
01:18 PM skunkworks: The raw video (avi) from the camcorder was 3GB :)
01:19 PM skunkworks: (recorded over fire-wire through VLC
01:19 PM skunkworks: (replacment cam corder because the one from the 90's died long ago)
01:19 PM PL7icnc: yu may use ffmpeg
01:20 PM skunkworks: I tried actually - Could not get it to work. VLC converted it though
01:20 PM skunkworks: Input #0, avi, from 'vlc-record-2019-05-28-17h01m56s-dshow___-.avi':

01:20 PM skunkworks: Error opening filters!
01:21 PM skunkworks: it doesn't seem to know what to do with 'dv' video...
01:21 PM skunkworks: PL7icnc: I don't normally see rod on here..
01:22 PM PL7icnc: woudt you like to get it scaled
01:23 PM PL7icnc: ffmpeg -threads 2 -i in.avi -strict -2 -acodec aac -ab 48k -vcodec libx264 -preset slow -crf 26 -r 25 -aspect 5:3 -s 800x480 out.mp4

01:25 PM skunkworks: Could not find codec parameters for stream 1 (Video: none (dv / 0x20207664), none, 720x480, 28765 kb/s): unknown codec
01:29 PM PL7icnc: does the video play in vlc
01:29 PM skunkworks: yes
01:29 PM PL7icnc: maybe in mplayer
01:30 PM Tom_L: pink_vampire, the part would be easy to print but tough to machine as shown
01:31 PM skunkworks: in vlc it says codec: DV Video (dv )
01:31 PM PL7icnc: can you try a convert to MOV
01:31 PM PL7icnc: ffmpeg -i xy.avi -acodec copy -vcodec copy xy.mov
01:32 PM skunkworks: It isn't finding the codec for the input file
01:34 PM PL7icnc: is this ffmpeg 4.1
01:34 PM Tom_L: working with linux tools?
01:34 PM skunkworks: 3.2.14
01:35 PM PL7icnc: Dv Digital Video workes only from 4.1
01:35 PM skunkworks: ah - thanks!
01:35 PM PL7icnc: you can just grap a run in place
01:36 PM skunkworks: we sure like to show the orient and move so the cutter didn't scrape the cylinder wall...
01:37 PM PL7icnc: https://johnvansickle.com/ffmpeg/
01:39 PM PL7icnc: i am off as tomorrow is off day DADS day in Germany getting lots of Bratwurst
01:40 PM skunkworks: pretty sure the spindle was still hydraulic too...
01:41 PM skunkworks: (at some point we swapped it out with a 5hp and vfd before we converted it)
01:46 PM perry_j1987: mmm i havnt grilled brats in alongtime
01:46 PM perry_j1987: i should do that maybe today heh
01:47 PM CaptHindsight: thanks, now I'm getting hungry
01:47 PM skunkworks: The salad I had for lunch isn't cutting it
01:48 PM Loetmichel: re from the notary... now the city has 4 weeks to transfer the money for 1/12 of the land i inherited to my account. knowing how german bureaucracy works i expect it in july ;)
01:51 PM CaptHindsight: slow but it works
01:52 PM CaptHindsight: not to bring up old war wounds, but who do you really blame for WWII? WWI was a mess from the start
01:53 PM Loetmichel: CaptHindsight: easy: all of the partiticipants
01:53 PM CaptHindsight: from the book entitled "Light bar conversation"
01:54 PM CaptHindsight: and how to get everyone to leave your dinner party
01:54 PM fragalot: Loetmichel: german bureaucracy is fun
01:55 PM fragalot: buy some property and the city goes "actually the previous owner never paid the electrical pylon 45 years ago. please pay this 750k invoice"
01:56 PM Loetmichel: fragalot: thats why i am happy that the CITY bought the land
01:56 PM Loetmichel: no surprises there ;)
01:56 PM CaptHindsight: in the USA you can discover old building code violations that were never fixed
01:57 PM fragalot: CaptHindsight: same here
01:57 PM fragalot: "oh btw your building was never registered, please demolish, kthx"
01:57 PM sync: in germany if it stood for longer than 10 or 12 years then so be it
01:58 PM fragalot: sync: here it mainly depends on who you know >.>
01:59 PM CaptHindsight: sync: are you in occupied France?
02:00 PM Loetmichel: fragalot: same in germany. but you get some "squatting rights" if it is like that for xx years
02:00 PM CaptHindsight: fragalot: they don't check when "closing" on a house here, you find out after purchase when you want to add a deck or fix the garage
02:00 PM CaptHindsight: so you have to check yourself before you buy
02:00 PM Loetmichel: so if the building was never registered but is standing tehre for (dont know) 15 years than you can register it retroactively
02:00 PM fragalot: CaptHindsight: you get told immediately after signing things at the notary office
02:00 PM CaptHindsight: hah
02:00 PM CaptHindsight: sounds right
02:00 PM CaptHindsight: bbl
02:01 PM fragalot: similarly they can say things like "also, you're in a flood zone"
02:01 PM Loetmichel: fragalot: correct. and if the seller didnt disclose that fact its a reason to nullify the enitre transaction
02:07 PM roycroft: title insurance can cover some of those problems, although its primary use for indemnity from defects in the title such as undisclosed liens and easments
02:09 PM Loetmichel: roycroft: as we sold to the city that wouldnt be a problem either
02:09 PM Loetmichel: actually there is a "water line" easement for the city on the title
02:10 PM Loetmichel: the major (that was there representing the city) "ah, that... yes, we will delete that shortly, no problem" ;)
02:12 PM pink_vampire: Tom_L: I got a quote for 3d printing (with no holes) Total: $39.92
02:54 PM Deejay: gn8
03:03 PM justanotheruser is now known as Mr_Notheruser
03:06 PM elmo40: pink_vampire, i'll make it for free. shipping to the USA might be the expensive part...
03:06 PM elmo40: you want the holes printed or will you drill it out?
03:11 PM pink_vampire: II can drill them
03:11 PM pink_vampire: I*
03:11 PM pink_vampire: elmo40:
03:12 PM XXCoder: pink saw that you got height gage, nice
03:12 PM XXCoder: one of more useful tools at work
03:14 PM pink_vampire: my height gauge https://i.imgur.com/Qo5btSy.png
03:16 PM elmo40: is that for the typewriter?
03:16 PM pink_vampire: no
03:17 PM pink_vampire: for the milling head
03:17 PM XXCoder: isnt that just regular caliper
03:17 PM elmo40: XXCoder, yes
03:17 PM elmo40: pink_vampire, plastic is strong enough?
03:17 PM elmo40: *layered plastic
03:19 PM XXCoder: elmo40: I know it is lol
03:19 PM pink_vampire: caliper in the vise on parallel on top there is 123 block
03:19 PM pink_vampire: work grate
03:19 PM XXCoder: so using that as height gage eh? not bad idea
03:20 PM XXCoder: using 123 as "rock" and also using it to align caliper to jaws not bad
03:23 PM pink_vampire: and the fact you have holes in the 123 block make it very easy to test the other side of the part
03:25 PM XXCoder: when you said height gage i thought you meant actual one tho lol
03:25 PM XXCoder: you need to get a rock though
03:25 PM pink_vampire: I need to get money
03:25 PM XXCoder: yeah
03:26 PM elmo40: dont we all...
03:26 PM XXCoder: rock smaller ones is quite cheap but not to person not currently getting income'
03:26 PM XXCoder: or fixed income
03:49 PM JT-Shop: or your self unemployed
03:53 PM XXCoder: yeah thats what currently not getting income is. :)
03:53 PM XXCoder: hows things JT-Shop
03:56 PM JT-Shop: not too bad, got a little refit job this morning
03:57 PM XXCoder: I think im very slightly allegric to broaching cutting oil
03:57 PM Tom_L: did you retire from making 'assembly lines' ?
03:57 PM XXCoder: i always gets headaches at end of shift if I run broaching job
03:59 PM JT-Shop: Briggs has slowed way down in the past years, dumb asses showed China how to make small engines by opening a factory over there
03:59 PM Tom_L: what fools
03:59 PM JT-Shop: I think they are down to 1 shift now dunno if both assembly lines are running or not
04:00 PM XXCoder: sucks :(
04:00 PM CaptHindsight: people just want low cost/free
04:00 PM CaptHindsight: they don't care where it comes from
04:00 PM JT-Shop: at one time the Poplar Bluff plant was the worlds largest producer of small engines
04:00 PM Tom_L: tariffs somewhat level the field
04:00 PM XXCoder: tariffs cost go direct to customers.
04:00 PM JT-Shop: well electric lawn mowers took a large chunk out of the small engine market
04:01 PM XXCoder: i want electric one but not plug types
04:01 PM XXCoder: mower running for hour equals 10 cars running for one hour in terms of pollution
04:01 PM Tom_L: i've had the same mower for probaly 25-30 yrs
04:01 PM JT-Shop: I sold my sthil gas trimmer and got a dewalt electric one that uses the same batteries as all my dewalt tools
04:02 PM Tom_L: i've got a sthil pole trimmer i'll keep
04:02 PM JT-Shop: I have a very old Sears rider with a 8hp engine on it... like to restore it one day
04:02 PM Tom_L: and a couple saws but i think my tree climbin days are past
04:03 PM JT-Shop: it ran when I parked it
04:03 PM JT-Shop: I bring the trees down to my level then cut them up lol
04:03 PM Tom_L: i wait til they fall to my level and do the same
04:04 PM perry_j1987: tree climbin shows you muscles you never knew you had... cause they ACHE the next day lol
04:05 PM JT-Shop: I have 3 big oaks that died last winter I have to get down if it ever stops raining so I can get the hoe back there
04:05 PM Tom_L: i used to help a friend with his lawn service now and then when he had a tree to trim
04:05 PM Tom_L: he hated it
04:05 PM Tom_L: it quit raining for a bit today so i mowed
04:07 PM JT-Shop: we only got a 1/4" or less this morning
04:08 PM Tom_L: it was misting this morning
04:09 PM XXCoder: jt was curious what your plan was with oaks lol. plan to cut and dry across year or so or?
04:10 PM Tom_L: he'll have to build a saw mill now
04:11 PM XXCoder: lol
04:12 PM XXCoder: thats true I dont think hes setup for wood stuff
04:12 PM XXCoder: could be wrong tho
04:13 PM jdh: I drove by the kansas Tallgrass Prairie National Preserver today. Not so toursity.
04:24 PM perry_j1987: no worlds largest tallgrass signs in 50 miles eh? :)
04:24 PM JT-Shop: my buddy down the road that I built the log arch for has a sawmill so some will be sawn up and rest for firewood
05:00 PM Tom_L: https://www.renishaw.com/en/nc4-non-contact-tool-setter--6099
05:00 PM Tom_L: i bet those are $$$
05:07 PM JT-Shop: yuck the water table is full of dross...
05:08 PM Tom_L: on the plasma?
05:09 PM sync: Tom_L: I have the blum version of those, they are around 5k$
05:09 PM Tom_L: my kid was telling me about the ones they have at the job he just started
05:09 PM Tom_L: aparently some of them you just toss tools in and press go
05:10 PM Tom_L: the machine probes em itself
05:11 PM sync: yes, of course
05:11 PM Tom_L: we didn't have all that fancy stuff
05:12 PM sync: it's not fancy
05:12 PM sync: the only benefit is, you don't have to have a presetter
05:12 PM Tom_L: well i know but still...
05:13 PM Tom_L: do the bench presetters scan the tool and give you a tool length to enter?
05:13 PM sync: what else would they do?
05:13 PM Tom_L: we didn't have those either
05:13 PM JT-Shop: yea and some dead bugs in there too lol
05:13 PM Tom_L: at least no rats... yet
05:14 PM sync: the question would be why you did not have any probing or presetting
05:14 PM sync: it really speeds up everything
05:14 PM Tom_L: i see that
05:14 PM sync: especially if you have reground tooling
05:14 PM Tom_L: yeah
05:14 PM Tom_L: it was a small shop and over 25 yrs back
05:14 PM Tom_L: that's the main reason
05:15 PM Tom_L: i can see that as being a real time saver
05:15 PM sync: they pay for themselves in no time
05:15 PM sync: the presetters are too expensive for what they are but they still save the time
05:16 PM sync: the cheapest ones are around 15k if you get a zoller one
05:16 PM Tom_L: yeah for machines that can't do that
05:16 PM Tom_L: that's what he was telling me
05:16 PM sync: no
05:16 PM sync: that's not entirely true
05:16 PM Tom_L: the cost i mean
05:17 PM sync: the machine takes longer than to have someone preset the tools
05:17 PM Tom_L: they do it both ways there
05:17 PM sync: and you can't do a batch
05:17 PM Tom_L: depending on the machine
05:17 PM sync: that's a strange way to do it
05:18 PM Tom_L: well this is all hear say.. i haven't been there
05:18 PM Tom_L: i know they have a bench setter
05:18 PM Tom_L: but he said some machines check their own
05:19 PM Tom_L: then probe the part when it's done
05:20 PM sync: yes, although probing in the machine is kind of a mixed bag
05:20 PM Tom_L: yeah
05:20 PM Tom_L: it could 'relax' once it's taken off the machine
05:20 PM sync: for setup it is usually ok but you have to have a very good machine to probe afterwards
05:21 PM sync: that's not really the goal tho
05:21 PM sync: as you are always measuring at the same time so the values are all relative anyway
10:12 PM perry_j1987: evening
10:13 PM justan0theruser is now known as justanotheruser
11:56 PM Deejay: moin
