12:13 AM roycroft: just roll it onto the main floor directly above where you want to put in in the basement
12:19 AM roycroft: it will find its way down
12:19 AM XXCoder: or invent teleporter if you want hardest way to do it
12:23 AM enleth: unterhaus: if you're in the US, just take the spindle to the nearest gunsmith and have them drill it through, it's about as long as a regular rifle barrel
12:24 AM XXCoder: i guess thye'd use gun drill for it
12:24 AM enleth: that's the point
12:24 AM XXCoder: indeed
12:24 AM XXCoder: my last job they use gun drill for one job alone
12:24 AM XXCoder: its very long drill
12:24 AM enleth: and they'll have a lathe long enough to do it
12:24 AM XXCoder: it was used inb mill lol
12:25 AM XXCoder: big machine
12:25 AM unterhaus: I don't know if it's hardened though
12:25 AM enleth: unterhaus: no
12:25 AM CaptHindsight: enleth: know of any Linux apps that could be used to compare laser scanned profiles https://youtu.be/wPW0alpNlwE?t=23
12:25 AM CaptHindsight: OpenCV could
12:26 AM XXCoder: capt cool
12:26 AM enleth: CaptHindsight: not really
12:28 AM enleth: unterhaus: bearing journals might be, but definiyely not the whole thing
12:29 AM enleth: taper definitely isn't
12:31 AM enleth: unterhaus: anyway, if you have a rigid ram mill with a quill housing extension and long spindle, fitting a drawbar is going to be a challenge
12:32 AM enleth: the spindle doesn't reach top of the varispeed housing even with the quill all the way up
12:32 AM unterhaus: I don't think it has a quill housing extension
12:33 AM unterhaus: been a while since I was up there though
12:33 AM enleth: does the head casting look like a manual BP?
12:35 AM enleth: or like this one: http://1.bp.blogspot.com/-swZ0HM0M1tU/URApV-l5aoI/AAAAAAAAATE/dfypbxKoEM0/s1600/bgpt+series+1+mdi.JPG
12:37 AM unterhaus: is it possible that the thing that says "MDI" on it could be gone?
12:37 AM unterhaus: that picture is very similar to mine
12:38 AM enleth: almost sure it can't - the Z ball screw telescopes into this part
12:38 AM enleth: it wouldn't have anywhere to go without it
12:38 AM enleth: also, it's the mounting point for Z motor
12:39 AM enleth: or do you mean the nameplate?
12:39 AM enleth: then yeah, sure
12:39 AM unterhaus: okay, it's like the one in your picture
12:39 AM unterhaus: that is pretty long
12:40 AM enleth: then you spindle doesn't reach the top like in a manual head
12:40 AM unterhaus: what do they do with all that room? It only moves 8 inches
12:40 AM enleth: as I said, the Z bsllscrew needs that space
12:41 AM enleth: *ballscrew
12:41 AM enleth: it's on top of the quill
12:41 AM enleth: in a manual head, the quill power feed screw is on the side of the quill
12:43 AM enleth: I'll be going now, but if you need any help modding that mill, I know this design inside out by now, just ask
12:43 AM unterhaus: do you know how to fix the air assist in the base?
12:43 AM unterhaus: I guess I have to take it apart
12:44 AM enleth: that's the one thing my version doesn't have
12:45 AM unterhaus: okay, thanks for straightening me out
12:46 AM enleth: in any case, I had that machine apart down to bare castings and boxes of loose parts
12:47 AM enleth: replaced varispeed with a 1:1 belt, rebuilt dog clutch from scratch
12:57 AM BleepCNC: Who can tell me how to invert an axis on a USB joypad input?
12:59 AM * BleepCNC on the console at the CNC so he can actually try the replies to stupid questions on a realtime loop.
12:59 AM XXCoder: :) dunno on that though
12:59 AM CaptHindsight: BleepCNC: invert in what way?
01:00 AM BleepCNC: I've got an old USB gamepad hooked up and working other than the Y axis is back-assward.
01:00 AM XXCoder: if cant invert it in any other way, you can always switch traces in it
01:01 AM CaptHindsight: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Using_A_Joypad_To_Move_Your_CNC_Machine
01:01 AM BleepCNC: X is Ok, haven't test the Z because it'll be the same fix as the Y.
01:01 AM CaptHindsight: a - before the sim-encoder.<n>.scale will change the direction if needed
01:02 AM CaptHindsight: https://forum.linuxcnc.org/38-general-linuxcnc-questions/29913-joy2key-using-a-usb-joystick-device
01:02 AM CaptHindsight: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Simple_Remote_Pendant
01:04 AM CaptHindsight: in the last example " * To reverse the direction of an axis add the following, in my case both Y and Z were backwards."
01:04 AM CaptHindsight: setp input.0.abs-y-scale -127.5
01:04 AM CaptHindsight: setp input.0.abs-rz-scale -127.5
01:06 AM BleepCNC: I've been working from the Simple-Remote-Penddant one.
01:37 AM Deejay: moin
03:04 AM CaptHindsight: frost on the windows already
03:04 AM CaptHindsight: we already hit 80F last week
03:05 AM XXCoder: dang
03:06 AM XXCoder: he have old ye timey machines too
03:08 AM bjorkintosh: completely amazed!
03:09 AM bjorkintosh: I've seen the full scale models at the Henry Ford in Detroit.
03:09 AM XXCoder: japanese oak nice
03:46 AM bjorkintosh: holy hell. <esc> . inserts the last argument to a command. also $!
03:46 AM bjorkintosh: how did I never know about this?
04:15 AM Tom_L: morning
04:15 AM XXCoder: yo

05:26 AM Loetmichel: *sigh* coworker managed to go to work with a cold... now half of the workforce here is coughing and sneezing. Good thing that the covid tests are still negative, but annoying nonetheless. Myself is already thru it mostly, i usually only have 3 days "fun" with a cold. But considering how many people are not working because of it our deadlines don't look good at all :(
05:26 AM -!- #linuxcnc mode set to +v by ChanServ
05:27 AM JT-Cave: morning
05:30 AM XXCoder: loet sigh
05:30 AM XXCoder: masks'd stop that
05:30 AM XXCoder: in japan you wear mask any time youre sick
05:56 AM Loetmichel: XXCoder: its not about masks. ists about "why didnt the "patient zero" didnt catch the cold in time to NOT infect all the other coworkers and decided to go to work regardless."
07:19 AM veegee: Bought a used Robinair 15600 for $150. Looks like it pulls a good vacuum. Also very high airflow, which is nice, but not a priority for me.
07:22 AM veegee: I bought the sum-ting-wong single stage pump for $80 new and it works 99.9% of the way which isn't bad at the end of the day
07:22 AM veegee: Should be good for getting air out of brake lines and stuff like that when used with a vacuum chamber

12:07 PM MrHindsight is now known as CaptHindsight
01:01 PM sinned69152 is now known as sinned6915
01:02 PM drdoc: veegee: I suppose I need to start shopping for a vacuum pump
01:03 PM drdoc: unterhaus_: that Enco table is up to $215 with a half-hour left. Gonna take your advice on that
01:03 PM unterhaus_: I thought it would be popular
01:04 PM drdoc: I'd say it'll go near $300
01:04 PM drdoc: if it stays where it is I might bid, say, $230 just to see
01:04 PM unterhaus_: I have a really nice x-y drill press vise and I'm impressed at how useless it is
01:05 PM drdoc: yeah
01:05 PM drdoc: recognize this label?
01:05 PM drdoc: https://ams-s3-onegoal-production-storage.s3-us-west-2.amazonaws.com/MUCIHNS5QK/26/swico_auctions_79158_2.jpeg?version=1618288443
01:05 PM drdoc: it looks very Kurt-like, but I'm fairly sure it's not a Kurt. 6"
01:06 PM unterhaus_: any other pictures?
01:06 PM unterhaus_: I wouldn't pay much for that, but the asian kurt clones are pretty good, usually
01:06 PM drdoc: https://ams-s3-onegoal-production-storage.s3-us-west-2.amazonaws.com/MUCIHNS5QK/26/swico_auctions_79158_1.jpeg?version=1618288442
01:07 PM drdoc: it's at $65 - I figure I'd go ~$100 but I wouldn't win at that
01:07 PM drdoc: https://swicoauctions.com/online/26/item/79158
01:08 PM drdoc: I have high bid on this one, much more my size:
01:08 PM drdoc: https://swicoauctions.com/online/26/item/79157
01:09 PM unterhaus_: new kurt clones are $300 now
01:09 PM drdoc: yeah
01:09 PM unterhaus_: The advantage of the Kurt design is you can flip the jaws for much larger pieces
01:09 PM drdoc: the ones that'll take kurt parts go for more
01:15 PM unterhaus_: what are you planning on doing with an xy table?
01:19 PM drdoc: put it on my big Grizzly drill
01:20 PM drdoc: Ugh
01:20 PM drdoc: got Ebay Fever
01:20 PM Rab: drdoc, haha, just checked IRC...I was camping on those auctions. 95% sure that's a older, rarer Kurt 5".
01:20 PM Rab: $175!
01:20 PM drdoc: well, I paid $175 for it
01:20 PM Rab: Oh, you got it?
01:20 PM drdoc: yes
01:20 PM Rab: Congratulations!
01:20 PM drdoc: were you bidding?
01:20 PM Rab: The X-Y table too?
01:20 PM drdoc: nope
01:21 PM drdoc: did get the little 4" for $75
01:22 PM Rab: No, I have a tiny mill with a 4" vise that's about right. I would have picked it up for ~$65, that would be too good to pass up...but it might have been too big.
01:22 PM drdoc: but the Baldor 2x48 belt grinder I was supposed to pick up today, the auction house just called and they double-listed it
01:23 PM Rab: If you look at Kurt 5" Ang-Lock pics online, damned if it's not the same vise.
01:23 PM drdoc: I dunno if I will end up with it or not
01:23 PM drdoc: well, that's an ang-lock label
01:24 PM Rab: Now you better hustle over the warehouse to make sure no funny business happens...or to see if you can spot a handle under the pallet.
01:24 PM drdoc: lol
01:25 PM drdoc: https://ams-s3-onegoal-production-storage.s3-us-west-2.amazonaws.com/MUCIHNS5QK/26/swico_auctions_79158_2.jpeg?version=1618288443
01:26 PM drdoc: yeah, the 4" is for my router/mill, the 5" will go on the Grizzly
01:26 PM drdoc: I was feeling silly about going that high on the 5"
01:26 PM Rab: G0407?
01:28 PM Rab: The 5" Kurt is highly sought after, because the more common 6" is pretty stupidly heavy for a smaller home shop mill. I would say <$200 is a great buy, if you need it (and if not, can probably resell it without much trouble).
01:28 PM drdoc: no, I don't remember the model # off-hand
01:29 PM drdoc: it's the old version of the G7946
01:30 PM Rab: Here is my mill & vise. The mill was $550 at one of the last live bid UT surplus auctions. http://reboots.g-cipher.net/mill/image/mill_rack.jpg
01:31 PM Rab: I max out the 4" vise now and then, but it's really the right match for the table.
01:33 PM drdoc: yeah
01:34 PM drdoc: that's a sweet machine
01:34 PM Rab: But I took the swivel base off the vise and got a rotary table instead. The base is pretty useless unless you have a good system for re-aligning the vise.
01:34 PM drdoc: yep
01:34 PM drdoc: I'd rather make fixtures for a stationary vise
01:34 PM drdoc: well shit
01:35 PM drdoc: our Old Lady cat is having her last vet visit this evening.
01:35 PM Rab: aww
01:35 PM Rab: How old?
01:35 PM drdoc: 16
01:36 PM drdoc: cantankerous old bitch, and by far my household favorite
01:36 PM Rab: That's a lot of cat years.
01:36 PM drdoc: yes
01:36 PM drdoc: she's probably got GI lymphoma
01:37 PM drdoc: not suffering yet but her weight's down to nothing and nothing's working
01:38 PM drdoc: the other auction folk just called
01:38 PM drdoc: they decided to give that double-listed Baldor to me
01:39 PM Rab: haha
01:39 PM drdoc: I do love me some Baldor spinniness.
01:39 PM Rab: Better than re-listing it.
01:40 PM drdoc: https://www.allsurplus.com/asset/284/9562
01:41 PM drdoc: there's some value to humoring chatty old secretary/bookkeeper/assistants
01:42 PM drdoc: the ACC blacksmith/welding shop has a couple of 2x72 grinders just like it
01:42 PM drdoc: pretty decent for a 2-wheeler
01:43 PM drdoc: there are plans floating around to make the 2x48 a vertical-face 3-wheel 2x72
01:46 PM drdoc: Rab: you have any use for a humongous Steelcase worktable?
01:49 PM drdoc: it's the 60x85" oval "mediascape: Collaborative" setup.
01:52 PM drdoc: https://www.steelcase.com/content/uploads/2019/05/150001098media_scape_education_brochure.pdf
01:52 PM drdoc: 3rd page, exacept it's a full oval
01:55 PM CaptHindsight: LPC1768 has a 6-12 month lead time and mnay of the boards that use them are out of stock as well
01:55 PM drdoc: dayum
01:56 PM CaptHindsight: which micro to port this to? https://remora-docs.readthedocs.io/en/latest/index.html
01:57 PM CaptHindsight: I think of point of using the LPC1768 Smoothieboard was that is has stepper drivers and other IO a CNC will use
01:57 PM CaptHindsight: BUT since it's not really available right now maybe there is a micro in ample supply that i can port this to
01:59 PM CaptHindsight: one the other hand.... the OrangePi CNC dev says that he has a new working stepgen but he won't publish until he tests it :(
01:59 PM CaptHindsight: so once again two steps forward and one step back
02:15 PM JT-Shop: 2 corner posts and one top tube for chain link fence cost $65!!!

03:03 PM Tom_L: nice looking cutters imo
03:12 PM CaptHindsight: STM32F407G-DISC1 >3k in stock but $20+ shipping
03:14 PM CaptHindsight: the new Rpi-pico is only $4-5 but Rpi
03:16 PM Rab: drdoc, no space, but Steelcase typically makes nice stuff...thanks anyway!
03:17 PM roycroft: i used to have some steelcase file cabinets, before i went on my scanning and shredding spree
03:17 PM roycroft: they were really nice
03:17 PM roycroft: they were like heavy duty file cabinets, but the metal was 50% thicker than the heavy duty ones
03:18 PM roycroft: if i lived in a tornado zone, i think hiding in one of my file cabinets would be the safest place to be during a tornado
03:18 PM roycroft: if i could fit
03:18 PM Tom_L: you might go for a bumpy ride
03:19 PM roycroft: i don't think i'd be in kansas at the end though
03:19 PM Tom_L: yeah just not where you started
03:19 PM XXCoder: Loetmichel: I know, what i meant is that at japan, if one is sick with anything, they wear masks for less spreading. :)
03:19 PM XXCoder: not just covid
03:21 PM roycroft: that's common in much of eastern asia these days
03:22 PM roycroft: they had the sars epidemic a few years ago, and learned the value of masking from that
03:27 PM roycroft: well thank goodness that's fixed
03:27 PM roycroft: i was migrating our network monitoring software to a new server
03:28 PM roycroft: the old machine i had put in our office, in private address space, for a few days
03:28 PM roycroft: and as a result it could not monitor anything
03:28 PM roycroft: i have a 3 day weekend coming up starting tomorrow, and did not want to spend another weekend manually monitoring things, so i've been working on the migration
03:29 PM roycroft: this morning i backed up the old server and restored onto the new one
03:29 PM roycroft: ran the utility to fix things up
03:29 PM roycroft: and things were looking good
03:29 PM roycroft: then the emails started
03:29 PM roycroft: there were over 1.4 million events triggered when the old server was in private address space, and all those events migrated to the new server
03:30 PM roycroft: i got no help from the vendor "because covid"
03:30 PM roycroft: but i finally found a table in one of the databases that held the event queue
03:30 PM roycroft: and the emails just now stopped
03:31 PM roycroft: now to cause a real event to see if new events trigger emails
03:32 PM roycroft: what sucks is that while i was looking for how to stop the emails i also had to babysit the mail server, because it kept throttling due to the huge incoming mail volume
03:44 PM perry_j1987: ahh what a nice warmer day finally
03:44 PM roycroft: today is our last nice day for a bit
03:44 PM roycroft: the rain returns on the morrow
03:45 PM perry_j1987: i just picked up a yamaha qt50 moped the other day heh
03:45 PM perry_j1987: took it out for a little ride today for some fun zipping around
03:45 PM roycroft: actually, i'm lucky
03:46 PM roycroft: it looks like it will just be overcast tomorrow, with the rain not starting until saturday
03:46 PM roycroft: i have some work on my gazebo that i want to get done before it rains next
03:46 PM perry_j1987: time to hhop to it
03:46 PM roycroft: i should be able to get that done in the morning
03:46 PM roycroft: well today after work i have to do some planing, sanding, and painting
03:47 PM roycroft: and i can't do the rest of the work until tomorrow, when the paint has dried
03:48 PM CaptHindsight: we had frost last night again
03:49 PM perry_j1987: snow last two days up here
03:49 PM veroski: hello
03:49 PM CaptHindsight: howdy veroski
03:50 PM veroski: hello capthindsight
03:52 PM veroski: i have buy mesa card 7i97 and 7i74 and 2 other card for i/o expansion. i've dowload mesaflash and build it. now i've download 7i97.zip from mesa and extract it.
03:53 PM veroski: the question is, what .bit i must use if i want use only 7i97 for try it?
03:54 PM CaptHindsight: sounds like a pcw_home question
03:54 PM veroski: what do you mean with pcw_home question?
03:55 PM CaptHindsight: he will have your answer
03:56 PM veroski: ah ok i understand. how can i contanct him?
03:56 PM CaptHindsight: he's here, just wait for a response
03:56 PM veroski: great
03:57 PM roycroft: grab a refreshing beverage
03:57 PM roycroft: he may respond almost immediately
03:57 PM roycroft: or it may be a while
03:57 PM CaptHindsight: roycroft: do you have any more of the virtual flanders red?
03:58 PM perry_j1987: you guys ever have that issue where you get out to the shop and just kinda stand there looking at everything
03:58 PM CaptHindsight: often
03:59 PM CaptHindsight: too many projects?
03:59 PM roycroft: i'm fresh out of it, sadly
03:59 PM roycroft: i haven't even virtually brewed in a while
04:00 PM CaptHindsight: the literal brewery near here make a pretty good one and since business was slow they were pouring it in very large glasses for $9
04:01 PM roycroft: nice
04:01 PM roycroft: a good flanders red takes a couple years
04:01 PM perry_j1987: i need to finish setting up some sort of touch plate solution on the 6040
04:01 PM roycroft: i do it in three twin batches
04:01 PM perry_j1987: and need to finish figuring out some gcode to do gang tooling on the lathe
04:01 PM roycroft: i get a fresh yeast/bug pack, brew a batch
04:02 PM roycroft: a couple weeks later i brew a second batch and rack it onto the yeast cake from the first batch
04:02 PM roycroft: six months later i do the same thing again
04:02 PM roycroft: and one more time six months later
04:02 PM roycroft: now i have six batches, and i blend them to make the final product
04:02 PM CaptHindsight: nice, bbl
04:03 PM roycroft: and let the blend age for six months, then do final packaging

04:10 PM veroski: i'll ask my question tomorrow. see you guys
04:28 PM -!- #linuxcnc mode set to +v by ChanServ
06:08 PM unterhaus_: I assume a 7i97 has a useful bit file on it as shipped. Unless veroski has one of the clones
06:09 PM JT-Cave: yea, it should "just work"
06:09 PM JT-Cave: are they cloning that too?
06:11 PM XXCoder: second shot done!
06:11 PM XXCoder: yay. hope reaction isnt too bad lol
06:12 PM JT-Cave: awesome
06:12 PM XXCoder: indeed
06:13 PM XXCoder: i saw my phone 5g increase from 2 bars to 5 too
06:13 PM XXCoder: kidding lol
06:13 PM Tom_L: some places here are turning back vaccine
06:13 PM Tom_L: rather than overstock it
06:14 PM JT-Cave: it's amazing how many people won't get it
06:16 PM XXCoder: that sucks yeah
06:19 PM unterhaus_: If I was an employer, I would fire anyone that won't get it
06:20 PM XXCoder: ehh may fall under some laws
06:20 PM unterhaus_: my sister is on lockdown again because she works with people like that
06:20 PM XXCoder: unless its "right to employ" (ironic) law state
06:20 PM unterhaus_: I don't know why at will employment doesn't cover that
06:20 PM unterhaus_: just don't say why
06:22 PM JT-Cave: no need to fire them just put them on a leave of absence until they provide documents that they completed the vaccine
06:22 PM JT-Cave: to protect the rest of the workers
06:22 PM unterhaus_: I think my sister's employer can probably afford that
06:22 PM JT-Cave: OSHA should step in lol as much as I hate them
06:22 PM unterhaus_: I can't believe they put up with it
06:23 PM unterhaus_: at least it's less stressful now that my sister is fully vaccinated
06:23 PM _unreal_: My progress https://www.cnczone.com/forums/controller-cards/419158-cnc-posts.html
06:23 PM unterhaus_: I used to worry every time because it wouldn't go well for her
06:24 PM JT-Cave: it's been over a month since we had over 9 cases a day in this county
06:24 PM unterhaus_: it's not quite out of control here, but 70-ish cases/day.
06:25 PM unterhaus_: outlying communities are starting to get it so that's bad
06:25 PM JT-Cave: most likely it's druggies and other low life that infect each other
06:25 PM JT-Cave: here anyway
06:26 PM JT-Cave: we are a larger rural county with about 43k people in the county
06:26 PM Tom_L: cutters came today
06:27 PM JT-Cave: how do they look?
06:27 PM Tom_L: day earlier than expected
06:28 PM Tom_L: kinda wicked

06:28 PM JT-Cave: the photo looked pretty mean
06:28 PM Tom_L: the end is ground kinda interesting
06:29 PM JT-Cave: not center cutting at all
06:29 PM Tom_L: comes to a point (center cutting) but it's got a pocket
06:29 PM XXCoder: looks like good rougher
06:29 PM Tom_L: i think it is actually
06:29 PM JT-Cave: IIRC my roughers don't center cut
06:29 PM Tom_L: normally not
06:29 PM Tom_L: i think one of the reviews said they plunge cut with it
06:30 PM JT-Cave: I seldom use a rougher as I'm usually on Island time now at my age

06:30 PM Tom_L: i wanted to try them
06:31 PM * JT-Cave clicks willy nilly because he has plenty of band width
06:31 PM Tom_L: just for the review
06:31 PM XXCoder: nice
06:32 PM JT-Cave: that one guy gave a great review
06:32 PM Tom_L: agreed
06:33 PM Tom_L: that's somewhat prompted me to try one
06:33 PM Tom_L: hard to get a good pic of the tip, i can try
06:33 PM Tom_L: it's got some interesting geometry

06:38 PM unterhaus_: I went through a phase where I would just quit after the roughing cutter

06:41 PM Tom_L: 45 deg tip chamfer
06:41 PM Tom_L: center is cut to a point
07:11 PM _unreal_: Tom_L, that is a mighty BIT

08:37 PM veegee: "For maximum performance, Robinair recommends changing vacuum pump oil after each use." LLOOOOLLLLLL
08:37 PM veegee: That's gotta be a joke right?

08:38 PM veegee: Not even the auto manufacturers try to pull that kind of bullshit
08:38 PM veegee: Some intern just stopped trying. No one's going to fall for that

08:39 PM veegee: It's a good pump, it's doing its job. Why do they have to go and make people lose respect for them like this?
08:39 PM veegee: They even got the grammar all nice and proper in the manual
08:41 PM W1N9Zr0: if whatever you're pumping has high moisture content, water will collect at the bottom of the pumping element and can cause rust
08:43 PM veegee: W1N9Zr0 that's literally every pump ever. Air compressors, internal combustion engines, etc.
08:43 PM W1N9Zr0: the vacuum pump oil is especialyl efficient at collecting the moisture
08:43 PM veegee: There's even a "gas ballast" port on this thing to mitigate moisture collecting in the oil
08:44 PM W1N9Zr0: if you search around, every manufacturer and HVAC tech site mentions the same thing, use ballast port, change oil every time
08:44 PM veegee: Should be easy enough to recycle the oil though right? Putting it in a vacuum chamber and heating it a little should be all that's necessary
08:44 PM veegee: Surely they don't just discard the oil though right?
08:44 PM veegee: It's easy enough to extract the water out of it
08:45 PM veegee: It's pretty damn expensive. But I guess for professionals, it's just an operating cost
08:46 PM veegee: roycroft This ^ must be upsetting to you haha based on how mad you got when I mentioned I over oil my machine tool slide ways
08:47 PM veegee: My total waste oil from that in a year is less than one vacuum pump oil change...
