03:27 AM pere: hi
03:41 AM travis_farmer[m]: G'Morning
04:25 AM Tom_L: morning
05:01 AM JT-Cave__ is now known as JT-Cave
05:01 AM JT-Cave: morning
06:03 AM Ma-Ryu[m]: Is anyone else using Virtual box to run the debian linux cnc iso
06:03 AM Ma-Ryu[m]: Senpai s
07:03 AM RatherLogical[m]: I run it on proxmox which is basically fancy virtualbox
07:04 AM jpa-: i run it under virtualbox for testing in simulation
07:04 AM jpa-: it complains about latency but works otherwise
07:14 AM Tom_L: 32°F
07:25 AM JT-Cave: 25°F
07:27 AM Tom_L: i'll keep what i got thank you :)
07:37 AM Ma-Ryu[m]: Caaan someone help me with installing virtualbox guest additions?I cant get full screen or have bidirectional copy pasting file sharing without it. I've been trying for an entire day. Its just a problem after a problem. I am stuck on gettging access denied from a file that i did use chmod on. very frustrating 😄
07:45 AM bjorkint0sh: Ma-Ryu[m], how did you go about the installation process? via virtualbox itself?
07:47 AM Ma-Ryu[m]: I did a bunch of commands then i got an Iso with Vb guest additions on it. It was supposed to autoruin but did not so i had to go in the folder and run it manually. After that it was a problem after a problem after a problem. its a single file i gotta run. finally i thought what if i load the iso on my windows. installed it on my windows. ran Vb again and opened linux cnc. Nothing.
07:47 AM bjorkintosh: did you mount it?
07:48 AM Ma-Ryu[m]: Yes
07:48 AM Ma-Ryu[m]: tried mounting and unmounting
07:49 AM Ma-Ryu[m]: But it did not run automatically. so i had to run the autorun.sh manually
07:49 AM Ma-Ryu[m]: But I could not
07:49 AM bjorkintosh: what OS are you doing this on, Ma-Ryu[m]?
07:50 AM Ma-Ryu[m]: Windows
07:51 AM Ma-Ryu[m]: 10
07:54 AM bjorkintosh: hard to say. do you have an old machine you can run it on instead?
07:56 AM Ma-Ryu[m]: No.
08:02 AM bjorkintosh: damn. does it report any errors?
08:06 AM Ma-Ryu[m]: yea. access denied
08:19 AM bjorkintosh: are you running with admin privileges?
09:02 AM -!- #linuxcnc mode set to +v by ChanServ
09:45 AM satiowadahc1171[: I don't know about virtual box, but docker needs alot of host resources passed through to run lcnc
09:50 AM JT-Shop__ is now known as JT-Shop
09:51 AM * JT-Shop might burn a stick of firewood today
09:53 AM satiowadahc1171[: There's no AND/OR in gcode conditionals right?
10:25 AM Ma-Ryu[m]: ya
10:37 AM roguish[m]: Ma-Ryu: you may get it to run sim in a VM, but seriously doubt you will get the real time part running real time.
10:40 AM roycroft: a real time kernel will run in a vm, but without even remotely appraching real time performance
10:41 AM roguish[m]: exactly
10:42 AM satiowadahc1171[: I run CI testing on my UI's with sim lcnc in docker. works good enough
10:45 AM justache is now known as justHaunted
11:15 AM roycroft: but are you making parts when you're doing your testing?
11:19 AM satiowadahc1171[: not on a physical machine. only in sim'
11:20 AM roycroft: and there's the rub
11:20 AM roycroft: you can't test real time performance reasonably unless you're actually making parts
11:21 AM roycroft: in sim mode, motion control delays of a few milliseconds won't be noticed
11:21 AM roycroft: when making parts, if you're lucky your part will be spoiled
11:23 AM satiowadahc1171[: Lately the one issue I've been having on my test mill is mesa keeps missing reads... about an hour in or so it misses a read and everything halts with an estop
11:24 AM satiowadahc1171[: I thought it was latency but setting servo-thread to 2ms didn't change anything. Swapped the ethernet cable for mesa to a nice shielded cable and it went from every 20 minutes to an hour but not sure what else it could be from
11:47 AM solarwind: Huanyang seems to actually be responsive and provide some support for their VFDs
11:47 AM solarwind: I actually got documentation for their RS485 protocol
11:48 AM solarwind: Now to try and get them to make 600V VFDs at a reasonable price for me
11:48 AM solarwind: The VFD control code for these models is a mess in the linuxcnc codebase. I wrote new drivers for them
11:49 AM solarwind: Also ZincBoy[CAON][m], https://www.omc-stepperonline.com/1000w-servo-motor these look like rebrands of the leadshine motors. Exact same specs, some of the model numbers are even the same, but much lower prices
11:50 AM solarwind: ZincBoy[CAON][m] 1000W servo + driver (same as the EL6) is $500 CAD
11:53 AM solarwind: ZincBoy[CAON][m] Similar package from DMM is at least $1,000 CAD
11:56 AM solarwind: pcw-home any plans for MESA ethercat interfaces? I'd love to go optical as much as possible
12:06 PM satiowadahc1171[: I believe pcw said hes not interested in ethercat a number of times on the forum and here. although it'd be nice 🙂
12:12 PM solarwind: satiowadahc1171[ thanks, not a problem
12:12 PM solarwind: Ethercat mostly eliminates the need for the mesa cards in general
12:13 PM solarwind: I like that you can do servo updates at > 10kHz over optical
12:29 PM satiowadahc1171[: Aren't most ethercat systems limited to fast ethernet speeds? even with fibre?
12:36 PM solarwind: yeah, that's still a lot faster than the analog torque/velocity bandwidth traditional servo drives
12:36 PM solarwind: 100Mbit/s is _a lot_
12:37 PM solarwind: eliminates the need of separate wiring for all the control signals. Everything is over EtherCAT. The computer just has to have a solid realtime ethernet interface
12:42 PM satiowadahc1171[: https://www.beckhoff.com/en-ca/products/ipc/pcs/accessories/fc1121.html
12:43 PM satiowadahc1171[: These work better than expected. Requires a seperate PLC for handling communication.
01:47 PM CaptHindsight[m]: most machines aren't built where Ethercat vs analog servos make a difference
01:50 PM CaptHindsight[m]: satiowadahc#1171: have fresh eyes look at your wiring and grounding practice, every used and hobby machine I come across has issues
01:57 PM CaptHindsight[m]: https://tracker.debian.org/pkg/linuxcnc lists the latest official debs, are there any other LCNC deb packages besides the buildbot being generated anywhere?
01:57 PM satiowadahc1171[: the ethernet cable is only parallel/near an unused USB and cross's a power line for lights... maybe I'll disconnect the lights for a while
01:57 PM CaptHindsight[m]: just asking since I have just been building them myself if I need more recent builds from master
02:00 PM CaptHindsight[m]: satiowadahc#1171: is there a latency spike on your servo thread about once an hour?
02:00 PM satiowadahc1171[: Not that I can tell. It used to be like 10 to 20 minutes before I swapped to a shorter CAT6A
02:02 PM CaptHindsight[m]: how far is the PC Ethernet port and the Mesa card apart?
02:02 PM satiowadahc1171[: 5 feet
02:04 PM CaptHindsight[m]: properly designed Ethernet is very robust , I was running DC power over Ethernet back in the 90's and the issues were always software even though everyone pointed towards my weird unregulated 48V DC in the same cables
02:06 PM satiowadahc1171[: Shielded at that is pretty powerfil
02:10 PM satiowadahc1171[: This mill gets rebuilt at least 3-5 times a year so cleaning it up seems pointless.
02:11 PM CaptHindsight[m]: I ran cables that were at least 100ft long with power
02:12 PM roycroft: shielded cable is not at all necessary for ethernet
02:13 PM roycroft: it's a differential signal, and if the wires are twisted properly and terminated properly it should be all but completely immune to interference
02:14 PM CaptHindsight[m]: we built tablet PC's that were used at the Boeing factory to replace climbing inside the planes with a roll of blueprints and wiring diagrams
02:15 PM CaptHindsight[m]: differential signals in theory are immune to common mode noise unless you get it wrong, which is often the case
02:17 PM CaptHindsight[m]: most people are confused by grounds vs neutrals vs shields and how to route conductors through the walls of control cabinets
02:18 PM travis_farmer[m]: not me, i am just generally confused... 😉
02:19 PM roguish[m]: roycroft: check out new cat7 and cat8 cabling. double shielded.
02:20 PM roguish[m]: I've been using it for my encoder cabling.
02:20 PM roguish[m]: each pair shielded, and an overall shield
02:20 PM CaptHindsight[m]: once had a RF welder for plastics that had awful wiring and power design, one of the control transformers inside the cabinet acted like a coupler for the outside 5KW RF into the controls power supply
02:20 PM travis_farmer[m]: i use STP wire for a lot of cabling, but only because i bought 1000ft of it when i meant to buy UTP cable...
02:21 PM roycroft: proper termination is the key
02:22 PM roycroft: and for signals that need to be shielded, continuity of the shield is the key
02:22 PM CaptHindsight[m]: this was before Chinese shortcuts in everything
02:22 PM CaptHindsight[m]: it's even worse now
02:24 PM roycroft: once upon a time i worked for a computer company up in bellingham washington
02:24 PM roycroft: we got a call one day from a start-up hydropower utility
02:24 PM roycroft: they had built a hydro plant in the cascades, about an hour and a half from us
02:25 PM roycroft: they needed to control a sluice gate a couple miles upstream of the power generation plant
02:25 PM roycroft: their plans called for burying a 50kv ac power line on one side of the river, and the control cable for the sluice gate on the other side of the river
02:25 PM perry_j1987: any of you guys profision with freecad?
02:26 PM roycroft: of course, both were buried in the same trench
02:27 PM roycroft: and of course, the signal was not getting through
02:27 PM roycroft: it turns out that not only were they both in the same trench, the control cables came in 5000' spools, and the shield was not spliced through
02:28 PM travis_farmer[m]: OMFG, seriously?!?!?
02:28 PM roycroft: they needed 300 baud, rs232
02:28 PM roycroft: i drove out there with a pair of telebit trailblazer modems
02:29 PM travis_farmer[m]: that's like using wire nuts to splice a cable TV wire...
02:29 PM roycroft: if you're not familiar with those, they are high speed modems that work in the worst of conditions
02:29 PM CaptHindsight[m]: they went with lowest bid on the work
02:29 PM satiowadahc1171[: lowest is lowest for a reason.
02:29 PM roycroft: they use a proprietary signalling, where they transmit on hundreds of frequencies, and sample them to see if any are suffering interference, and they block those out
02:30 PM roycroft: the modems were designed to transmit data in remote locations like africa and nepal
02:30 PM roycroft: anyway, i went out there, hooked them up, and they had a solid 19.2kilobaud signal instantly
02:31 PM travis_farmer[m]: now, they would likely just use fiber-optic, i bet
02:31 PM roycroft: this was in the late '80s
02:31 PM roycroft: i left them a spare modem, in case one failed
02:32 PM CaptHindsight[m]: Chinese fiber transceivers actually work and are cheap now
02:32 PM roycroft: the one at the sluice gate was installed underground, in a waterproof container, and was buried by several meters of snow in the winter
02:32 PM roycroft: pretty harsh conditions
02:32 PM roycroft: i checked in with them after about five years, and everything was still working
02:33 PM roguish[m]: roycroft: I don't remember those modems, but I do remember 300 baud....
02:33 PM roycroft: if the shields had been connected properly the original system might have worked
02:33 PM roguish[m]: timesharing from Sunnyvale, CA to Pittsburgh, PA
02:34 PM CaptHindsight[m]: a shield for a differential signal :)
02:34 PM roguish[m]: I worked at Westinghouse in Sunnyvale. Westinghouse computer center was in Pittsburgh. Big Cybers, and a couple of Crays.
02:35 PM roycroft: https://en.wikipedia.org/wiki/Telebit
02:35 PM roycroft: look at the section titled "PEP and the TrailBlazer"
02:37 PM roguish[m]: Timesharing on the Cybers, and submitting batch job runs to the Crays. all at 300 baud, small simple Wyse terminals, and a couple of Techtronix storage scope graphics terminals. try watching those at 300
02:38 PM roycroft: there used to be a sprint network called "telenet"
02:39 PM roycroft: with it one could dial up to a local modem bank and get dialtone in a remote city (in the us)
02:39 PM roycroft: the network had a nice fixed-rate price for after hours, which iirc was 6pm to 7am
02:39 PM roycroft: and they had telebit modems
02:39 PM roycroft: i used to get my news/email feed from a provider named jolnet, in joliet il
02:40 PM roycroft: i was in bellingham wa at the time
02:40 PM roycroft: i had a cron job that would connect to telenet at whatever time my plan started, and made a uucp connection to jolnet, where i exchanged usenet and email
02:40 PM roycroft: this was before the public internet
02:44 PM roycroft: i did beta testing for telebit when they were working on the worldblazer
02:44 PM roguish[m]: back in the olden daze
02:44 PM roycroft: and when i started my isp up in bellingham i used a bank of telebit modems for the indials
02:45 PM roycroft: and if any of you are into packet radio, you'll appreciate this
02:45 PM roguish[m]: hey, I started with punched cards, too
02:46 PM xxcodery: Im still sad I missed the BBS days
02:46 PM roycroft: for the "terminal server", i used a 486 with some smart serial cards (maxpeed), and we used a version of ka9q that my business partner hacked to support ppp and slip/cslip
02:46 PM xxcodery: by time I heard of bbs it wasnt a thing anymore
02:46 PM roycroft: my first computer use was in high school
02:49 PM roycroft: another high school in the district had a pdp-9, and we had a tty terminal with the yellow paper and a paper tape reader/punch
02:49 PM roycroft: we dialed up the other campus with a 300 baud acoustic coupled modem
02:50 PM roycroft: i learned basic on that
02:50 PM roycroft: i finished the basic course in a couple weeks, and for the rest of the semester i learned fortran
02:50 PM roycroft: one of my classmates' father was an executive at a company who had an ibm 360 mainframe, and i was able to run my fortran code on that
02:51 PM roycroft: i would fill out a coding sheet, give it to my classmate, who would give it to his father that night
02:51 PM roycroft: the next day the father would take it to work, have a card deck punched from the coding sheet, and would submit the deck to be processed
02:51 PM roguish[m]: didn't know anything about computers in HS...... not until college. and basic was the first language....then fortran
02:51 PM roycroft: he would bring home the printout that night, and my classmate would give it to me in class the next day
02:52 PM roycroft: i learned to code carefully, since there was a three-day turnaround for getting results
02:55 PM roycroft: well i just found out why the towing company never showed up to haul away my old pickup
02:55 PM CaptHindsight[m]: I never took any of the tech courses in HS, they would have ruined anything interesting, they could suck the joy out of a class on fireworks
02:56 PM roycroft: there was a 60+ vehicle wreck just north of eugene early this morning, including at least one fatality
02:56 PM roycroft: i5 is closed both directions, and it's apparently a huge mess
02:56 PM roycroft: the cause of the wreck?
02:56 PM roycroft: fog
02:56 PM roycroft: so they say
02:57 PM roycroft: the actual cause of the wreck is that 80% of drivers are impatient and follow way too close
02:57 PM xxcodery: did rain happen?
02:57 PM roguish[m]: Canadians...
02:57 PM roycroft: not until friday
02:57 PM roycroft: not down here
02:57 PM roycroft: when i lived in bellingham we would blame canadians for everything
02:57 PM roycroft: and most of the time we would be right :)
02:57 PM xxcodery: yeserday night it rained briefly. enough to wet some thing
02:57 PM CaptHindsight[m]: why don't they just post "stupid people" as the cause and the dumb thing that they did?
02:57 PM CaptHindsight[m]: oh yeah, there are no stupid people
02:58 PM satiowadahc1171[: They started kinda doing that here
02:58 PM roycroft: note that i did not use the word "accident", which is what is being reported
02:58 PM roycroft: because there are very few "accidents"
02:58 PM roycroft: i use "wreck", which has no connotation
02:58 PM CaptHindsight[m]: there are no such things as accidents
02:58 PM CaptHindsight[m]: there is always a reason
02:58 PM satiowadahc1171[: leave the vehicles for a while, with listed dui/following to close/didn't stop at stop sign... etc.
02:59 PM Tom_L: won't be getting a plug in car any time soon: https://www.youtube.com/watch?v=X5NiWJcyrwI
03:00 PM CaptHindsight[m]: impatient and incompetent, what could go wrong?
03:00 PM roycroft: well, a common definition of an accident is an "unexpected event"
03:00 PM roguish[m]: NEVER buy a flooded car................any one, any type.
03:00 PM roycroft: a fluke failure of a brake component that causes a wreck would be unexpected
03:00 PM Tom_L: you may not know...
03:00 PM xxcodery: rog exactly
03:01 PM roycroft: rear ending someone because you're following too close and it's foggy is not "unexpected"
03:01 PM xxcodery: flooded car of any kind is bad.
03:01 PM roycroft: it is the opposite - it is "assumed"
03:01 PM roguish[m]: face it. there
03:01 PM roguish[m]: there's a lot of really shitty drivers.
03:02 PM Tom_L: i thought they all lived here..
03:02 PM roycroft: cars blow up all the time
03:02 PM xxcodery: my uncle died suddenly by car steering wheel suddenly disconnected and car turned on bridge and went over
03:02 PM roycroft: i'll say that, while not many evs have caught fire from being flooded, it would be prudent for ev designers/manufacturers to make them less prone to bursting into flame when flooded
03:02 PM xxcodery: accidental. its not a wear part
03:03 PM roycroft: that's a fluke defect
03:03 PM roguish[m]: I watched an old lady push her walker up to her Prius, get in, and drive away. she could barely walk, even with the walker, but still driving......... frightening
03:03 PM xxcodery: we desperately need batteries thats in least as good as lathium ion but not so explosive to water
03:04 PM roycroft: what you did not see was one of her children taking her where she needs to go
03:04 PM xxcodery: ponentally no kids
03:04 PM roycroft: possibly
03:04 PM CaptHindsight[m]: don't they test old drivers yearly for competence, people over 50 or 60 :)
03:04 PM roycroft: not well enough
03:04 PM roycroft: speaking as one of those old people drivers
03:04 PM roguish[m]: no one else around her.............totally solo
03:05 PM Tom_L: there are just as many bad ones in a freakish hurry on a phone
03:05 PM Tom_L: that aren't old
03:05 PM roycroft: after age 64 or so drivers licenses should be renewed at least every two years
03:05 PM Tom_L: likely more
03:05 PM roycroft: not every eight years, as they are here in oregon
03:05 PM CaptHindsight[m]: question 7: Did driver yield to traffic or drool?
03:05 PM roycroft: and older people should be required to take both a written and a road test at every renewal
03:06 PM roycroft: i say this as an old person who is still a competent driver
03:06 PM Tom_L: so you're for discrimination?
03:06 PM roycroft: how is that discrimination?
03:06 PM Tom_L: grouping ppl in a 'class' saying they must do something different than the rest
03:06 PM CaptHindsight[m]: we don't want that here, get your thinking crap outta my drivin!
03:07 PM CaptHindsight[m]: our current system keep the chaos at acceptable levels
03:07 PM CaptHindsight[m]: sane driving rules and enforcement would mean safer and faster commutes
03:07 PM roycroft: if it's based on statistical data it's not discrimination
03:07 PM roycroft: if it's arbitrary it is
03:08 PM roguish[m]: I don't care if drivers kill themselves, but there actually are innocent people out there also.
03:08 PM CaptHindsight[m]: are they really innocent in a democracy?
03:08 PM roycroft: and btw, speaking also as a non-speeder, the feds are trying to push legislation that would require new vehicles to have devices to prevent speeding
03:08 PM CaptHindsight[m]: these laws and enforcement didn't make themselves
03:08 PM roycroft: i am vehemently opposed to that
03:09 PM Tom_L: there are as many 20's out there on crotch rockets being alot more stupid
03:09 PM roguish[m]: and to have anti-dui devices.....
03:09 PM roycroft: anti-dui devices i'm ok with for people convicted of dui
03:09 PM roycroft: but as a preventative, not so
03:09 PM CaptHindsight[m]: it's more political circus
03:10 PM roycroft: but the speeding thing is different
03:10 PM roycroft: because there are situations where the only safe thing one can do is speed
03:10 PM roycroft: i'm talking about avoiding wrecks
03:10 PM roguish[m]: ah go to Germany
03:10 PM CaptHindsight[m]: drunk driving is good for the auto industry (repair and manufacture)
03:10 PM roycroft: sometimes there is no safe way to slow, stop, or swerve to avoid a wreck
03:11 PM roycroft: the only thing you can do is accelerate
03:11 PM CaptHindsight[m]: not much good change will happen until we stop the lobbying
03:11 PM roycroft: especially in ai world where 80% of drivers follow too close
03:12 PM CaptHindsight[m]: "but i might be late to the not important things I'm driving to"
03:12 PM * roycroft belives more in paying the price when doing something stupid vs. the state preventing people from being able to do something stupid, ad a general rule
03:12 PM roycroft: that makes me not a good democrat
03:12 PM roycroft: so it's a good thing i'm not a democrat :)
03:12 PM CaptHindsight[m]: "so I have to tailgate to move traffic along"
03:13 PM roycroft: which is counterproductive when they're behind me
03:13 PM roycroft: because i believe in maintaining a safe distance between vehicles, and that distance is dependent on speed
03:13 PM roguish[m]: the legislature pump out the laws. it's just that no one enforces the laws very well......
03:13 PM roycroft: so if the distance is too little for the speed at which i'm going, i adjust my speed to match the distance
03:13 PM xxcodery: people behind me too close find out they would be unable to follow me that precisely
03:13 PM roguish[m]: a car length per each 10mph
03:14 PM CaptHindsight[m]: roguish: they do to if you are the right minority
03:15 PM CaptHindsight[m]: some get extra justice, on the spot :)
03:15 PM roguish[m]: CaptHindsight: naw, not even then.............
03:15 PM CaptHindsight[m]: look how the police hire and how they are held accountable, what do you expect to happen?
03:16 PM CaptHindsight[m]: making people accountable so very boomer
03:17 PM roycroft: i use the two second rule to establish a safe following distance
03:17 PM roycroft: it's easier to count time than to eyeball distance
03:17 PM roguish[m]: so, is that wrong? shouldn't people be accountable for their actions?
03:18 PM CaptHindsight[m]: not for police or higher offices in guberment
03:18 PM CaptHindsight[m]: accountability is for plebs
03:18 PM roycroft: for the plebs of a certain class
03:19 PM CaptHindsight[m]: it's a broken and corrupt system, just not as much as many other places, and we can't get enough people together to fix it
03:19 PM roguish[m]: well, I'm a boomer pleb...........and like it. except that as an older, middle class white guy, I am now the scourge of the earth............
03:20 PM roguish[m]: EVERYTHING is my fault
03:20 PM CaptHindsight[m]: then why did you let this all happen?
03:20 PM CaptHindsight[m]: 40+ years of voting
03:21 PM roguish[m]: wrong place at the wrong time.
03:21 PM CaptHindsight[m]: personally I see lots of differences between those on the older end of boomer vs younger
03:22 PM CaptHindsight[m]: 80-ish vs 60-ish
03:22 PM roguish[m]: i'm at the younger end.........
03:23 PM CaptHindsight[m]: also depends on who you listen to, the 20 somethings I talk with expect me to blame everything on them
03:23 PM CaptHindsight[m]: and I blame most things on my stupid and selfish generation, being a boomer myself
03:24 PM Tom_L: good there isn't anything lcnc to discuss today
03:25 PM CaptHindsight[m]: and that is why we can't have good network cables
03:26 PM CaptHindsight[m]: or have retrospective examinations of our actions and beliefs
03:43 PM satiowadahc1171[: 2 drivers for the xhc pendants... both are giving me grief may need to dive into these
04:01 PM pere: roguish[m]: how is your git foo coming along?
04:03 PM * JT-Shop2 takes 5 now that the upper a arms are off...
04:26 PM * JT-Shop2 listens to Leave Fall by Nickel Creek and it appropriate for this time of year

07:16 PM xxcodery: skunkworks[m] ahh so door is thicker with hollow inside
07:16 PM xxcodery: that explains the leak from door
07:17 PM skunkworks[m]: yes - water is in the door. didn'
07:17 PM skunkworks[m]: didn't want to have to use fire bricks. ever.
07:21 PM xxcodery: whats that thing anyway the box with door
07:21 PM xxcodery: kiln?
07:25 PM skunkworks[m]: outside wood furnace. (heats the water to heat the house)
07:26 PM skunkworks[m]: and shop
07:32 PM Tom_L: radiators or in floor tubes?
07:32 PM skunkworks[m]: yes
07:33 PM skunkworks[m]: 🙂 both. the house has under floor heat and radiators - the shop has in floor heat and radiators.
07:35 PM Tom_L: so it heats the waterjacket and i assume there's a pump circulating it
07:35 PM xxcodery: skunk nice
07:49 PM skunkworks[m]: yes - exactly
07:53 PM xxcodery: interesting indeed. so youre working on refinishing inside so its free from rust or?
07:57 PM skunkworks[m]: inside? like where the water is? or the fire box?
07:57 PM skunkworks[m]: I guess there is a water treatment you can use in boilers so that it is less likely to corrode.. We are going to try that.
07:57 PM xxcodery: honestky not too certain how it works
07:58 PM xxcodery: do it have fire inside and pipes go around it to make hot water to warm other places?
07:58 PM skunkworks[m]: the inside of the firebox has a layer of creosote.. Probably not going to do anything with that.
07:58 PM skunkworks[m]: there is a water jacket all the way around the fire box. Plus some tube that go through the fire box.
07:59 PM xxcodery: interesting'
