Horizontal Boring Mill in Action - Boring a Vacuum Pump Housing - Manual Machine Shop

- A badly worn bore on a Vane type vacuum pump will cause it to not pump. That was the case for this farmer. It was quite choppy inside causing the vanes to bounce and not pump at all. These pumps create the suction for the milking machines, without it, you must milk by hand.
Follow along with our setup and running this interesting job on the Lucas horizontal boring mill.
Topper Machine LLC is an entirely manual machine shop located in Spooner, WI. Our videos will highlight some of our shop work as well as the sawmill we built in the shop and our A.D. Baker steam engine, and others we work on.

I'm glad you made another new customer. I hope you keep growing.
That Lucas horizontal mill is a beast.
Loved the entry... it was stellar! "Always pass on what you have learned."-Yoda
Love your channel. I'm in my 80's now but many years ago I worked in an Ordnance Factory, no cnc machines, no digital readouts but we produced using micrometers, verniers slip gauges and dial indicators the most intricate parts for heavy artillery guns naval guns and rotary aircraft engines. Best wishes to you, keep pn with your REAL engineering.
Not many kids know how to manually indicate a part anymore. Even my boss watches when I use my co-ax indicator in my CNC. I even used to run a Lucas back in the 80s. Keep up the good work. I love seeing the old ways.
I honestly don't understand that. Isn't that one of the first things to learn is how to indicate parts/workholding? Sad state this world has come to.
@@TopperMachineLLC it’s all automated now. Not even edge-finders are used anymore. They have “probes” and “probing cycles”. Machinists are taught to program and calculate speeds and feeds. Nobody just feels the spindle or listens to the tooling.
@@eriktheredd6036 I learned feeds and speeds, but found that it's only a base line. Feel and sound will dial it in for more production and better cuts or tool life.
Love that mill! I thought it would be necessary to hone the pump body. Thanks for sharing.
I machine most part of the day and in my free time still watching other people machining XD, I wish I have the space for a boring like yours
Good video it is.
Good intro
Another great job. You are now beginning to get used to horizontal boring.
I've had this machine 8 years and have done little boring until this year.
Great video Josh, hope you get alot of job's in the future, looks like it's up to the people to make America great again. Lol..
A brilliant intro, very creative. first class and I made me smile for hours. The rest of the video was up to your usual high standard as usual
Very nice Topper
I enjoyed the whole video but absolutely loved the intro.
My uncle used to rebuild these vacuum pumps in the fox valley 20 years ago. Even back then there was a real shortage of people willing tl take on the job. I used to machine the fiber vanes down to fit thd inner pump slots by sticking to ths table on the bridgeport with double side tape so i could fly cut it in one pass.
I've only used the tape method a couple times. Worked great. If this could become a regular job, I'd look into a vacuum chuck.
The quality of this video is far above the others. Great work lots of camera movement. Nice job!
Yes for sure.
Love the intro, great lighting improvement 👏.
Thanks for sharing.
Nice job sir. We just retired our Lucas boring mill a couple years ago. It made the company a lot of money over the years !
But it would have cost them a fortune to repair...the spindle was just too far gone.
Its been replaced by a Wotan from the late 70's. And yes, my co-axial indicator is the best tool i've ever bought. It saves so much time !! It just depends how much $ you want to spend. $100 or $1000. Anyway, great video...and yes...set ups are three quarters of the battle. I have spent 6 hours setting up 20 minute jobs on the boring mill.
I would be lost without my HBM. Doesn't get used a ton, but when it does it makes money. Mines in great shape yet, saw very little use it's whole life. Just some minor repairs and upgrades to still do. Thanks for watching.
Greetings from OZ..You have a lot of interesting jobs and it makes enjoyable viewing..Well done..
Very good video, thanks Josh.🗜
Gotta love the bigger machines! I've never ran a lucas but we have a handful of Devlieg mills that i enjoy to run.
Great job. Happy Thanksgiving, thanks for sharing. Really nice to see your boring mill on the job.
I loved the intro!
Absolutely hated the useless music threw out the video.
Great montage. But you could make the still a tad longer as it is hard on the eyes and the brain when you jump rapidly from one to the other.
I would like to actually see more work done on the horizontal boring mill!!
Thanks for sharing and God Bless.
Thanks, this was an experimental video to see where to go next.
Have to agree about the 'music', turned the volume off. The shadow and pixelation made it look as if there were blemishes in the bore, which of course there weren't. Love to see the variety of work you do, Josh.
I totally agree. The intro made me laugh. The music was way too much though. These should not be music videos. Ok, seeing Josh doing a tap dance might be of some vague interest, as long as it is him making thread cutting taps dance.
Looking awesome Josh!!!
Love the soundtrack
Great intro!
Thanks for the great video.
Love watching that type of work great job well done
Nicely done Josh. Next time I come back to my roots in Minnesota, I will make a stop in Spooner for a tour.
Sounds good. Try to give me a little notice, but you're welcome to come check the place out.
Would absolutely love to see even just a short clip showing the control overview on the lucas boring mill. I’ve always wondered how you engage the quill feed on that model compared to on a Giddings and Lewis where you just pull in the handle in the engage the feed which works great for peck drilling. Thanks!
Thats a difficult one to explain. The hand feed is the 2 levers similar to your G&L. The hand wheel is the fine feed, which you have to engage by magic. The power feed is there also and all interconnected. Yeah, I didn't do a good job explaining that. But it's not easy to explain. Lol
I need one of those locks for mine.
The sound is missing from around 1:30 for a few minutes, not sure what's up or if it's a local error. I'm guessing it's probably on my end since nobody else has mentioned it, but noting it now anyway in case TH-cam corrupted the file somehow.
Made me smile.....
Always wanted to have shot at repairing these pumps, but it consider not cost effective. I worked for a short time in the dairy industry at the havest end. We'd repair, upgrade and do call out work to herringbone & rotary dairies. The Alf Laval pumps would suffer this damage, corrigations of bore. Thought to come from lack of lube, or running to fast (ie, motor and pulleys speed incorrect), or a combination of both. There are two little lube lines, one going to each bearing and seal side. The 2 pots that supply vacuum oil to these can get blocked with mostly tiny insects. It is possible to adjust flow with the metering screws. Bearings have their side seals removed and lips seal are installed back to front to deal with the vacuum. Lids should always be reinstalled to keep foreign matter out of pots.
Always wondered too, if after how many rebores does one have to raise bearing centres, ie repin cover plates. As that how vane pumps work, with a compression zone?
We bought one of those co-axial indicators last time you showed it but we have not needed to use it yet, however I am sure we will. Great job with the pump and it was great to watch all the steps and details, thanks
I'm glad you got one. Once you find the first use for it, you'll use it all the time.
Josh- I like the new video format. Nice star wars into. I like how you only show a shot for 5 or 10 seconds and then switch to another angle or another shot. I think it keeps interest high. Anyhow, maybe you have seen in my last video, I posted a picture of a Davis type draw key. It was for Dale in Alaska who just got a G&L mill like I have. Nice to see your key. I assume the internals are about like the one I had pictured. Would be nice to see for sure. Maybe draw on it in magic marker to show what the inside looks like and show it in a future video. As for the coax indicators, I have a Blake USA model and a Links China model. Believe it or not, I like the Links China model better. Maybe not a fair comparison, as I got my Blake from work because someone ran it at 3000 rpm and it went the shank ! Simple CNC mistake, don't ya know! Ha ! Anyhow I reground the bent spindle round and straight again and it works fine. It still has a small dither around zero, and the Links indicator has less of a dither, almost imperceptible. Just another thing that bothered me about the Blake, is that the instructions that included in the wood box look to have been photo copied like 100 times over, and it is a really poor quality document. It just screams, "I don't care". I think the final production of Blake indicators was sold to a mom and pop machine shop, and it is sadly evident. Anyhow, I see you have a larger Chandler boring and facing head. Keith Fenner has one like that I believe. I always liked how adjustable those are. I know it is beyond the scope of what you are doing, but I have to believe there is something making those pumps wear out. I know with any vacuum pump, passing debris is always going to be a problem. But with those chatter marks from the pump vanes, I think something is wrong, making the vanes chatter. I have seen centrifugal pressured vanes and also vanes with springs. Something is causing them to flutter and skip. Just my observation. Anyhow, love the HBM footage. Always interesting for me to see. ---Doozer
Thanks Doozer. Can you email me that drawkey info. I saw your video, but didn't screenshot it. Mine is a similar principle but all done internally. Wish I could have gotten the original to dissect and copy. I like my chandler head, so versatile and very inexpensive in comparison to others. The pump is not my project, otherwise I would dig deeper. But it has ran for 20 years 3 hours, twice a day. But I'm guessing by the wear it was contaminated. More wear in middle between inlet and outlet. Once the vanes start bouncing, it will get worse.
Awesome video, with great opening intro graphics. Good editing, mixing still shots into the video. At one point did you stick the camera to the boring head? wow.
Holy crap......what's the name of the Hollywood producer you hired to make this video. It's excellent!
I was being creative. Glad you liked it.
Very nice Josh.
I have did a couple of these in my cylinder block hone years ago.
Would have been nice to bore first then hone.
Nice work.
Gotta love the HBM!!
Great content.
Thank you, EM.
sounds like the music guys listened to 38 special a lot
If you hand grind the nose-radius off the insert with a diamond wheel, you can take light cuts without the chatter. Even with a longer bar like that.
That was one I ground. I edited it out, but I tried a couple different grinds. I think the problem was in my bar. But slowing it way down did the job nicely, and I could do other things.
@@TopperMachineLLC I think the bit was sticking out pretty far from the bar.
@@kmcwhq it was, but that's the only way I could do it. The bar holder would have hit the part otherwise.
Did you make the boring head?
Hi! Interested in the device for fixing the tool in the cone, can I learn more about it? thanks
Does the pump have fiber vanes ,and is the machined surface the final finish ?
surprised you didn't indicate the face of the pump to ensure the bored hole is perpendicular end faces.
Some things get cut in editing, or I forget to hit record. Rest assured, it got checked.
I would like to ask what kind of knife do you use?
nice job on that housing what make is the boring head you using
It's a chandler duplex
@@TopperMachineLLC ok thanks looks good and sturdy
Can't go wrong with some HBM action.
you said "we don't need to take much" and then the sound disappears. I tried playing in MPV instead of chrome and the same thing happens.
were you boring with the spindle or did you have the spindle locked and bore with the table?
Spindle. I have 24" of travel
Where did you get the taper lock for your mill did you buy it or build it?
I asked before I watched. Lol
Yeah I made it. Probably will make more in future and film it.
@@TopperMachineLLC I need one for mine will be bringing my mill in the shop in about a week or two and clean it up then build one.
What is LLC stand for sir?
Limited liability company
Are you from
I am assuming that is a cast iron pump. I would have thot for dairy industry it would be stainless..
Yes cast. It's not in contact with the milk at anytime. Just pulls the vacuum on the milking system.
1;30 to 3;07 has No Audio*****************
if you skip the f@king music i wil hit the bel button.
cheers ben.
The music junked another video 👎👎👎💩💩💩😬😬
So, would you rather it just be machine noise? I'm trying to find the groove that is good all around. Just not sure where to go.
@@TopperMachineLLC yes or talking
@@daleolson3506 ok. I'll just do that. It's less work anyway. Thanks.
I enjoyed the whole video but absolutely loved the intro.
Josh, please, please, please ditch the music. There's enough genuine sound eminating from the tool's cutting action to negate needing
?Music?
Otherwise a very interesting video. Pity we lost audio during the setup stage.
