SNS 360: American Pacemaker Compound Tear-Down For Rebuild
ฝัง
- เผยแพร่เมื่อ 27 ส.ค. 2024
- I begin the repairs on the American Pacemaker compound slide. We'll begin with a disassemble which proved to be a challenge in itself. Once we get it apart I'll get everything cleaned up nicely and go over the plans I have in store for the repairs. We'll also start working on the t-nut needed for the new PeWe Tools Multifix Tool-post I will be mounting to it.

I am watching your channel for over 8 years and never get bored. Greetings from SLOVAKIA
Hell yeah, one of my favorites too. Greetings from Italy
It is so important to talk about your Grandad and his tools. He really made you what you are, a machinist, and a good one!
If there is enough length to the brass nut, you can incorporate a backlash adjuster by making a 2/3 deep hacksaw cut 1/4" from the end of the nut. At the beginning of that cut, drill two holes in that 1/4 section and tap them. All you have to do then is adjust the backlash by tightening the screws. This closes the gap on that saw cut and picks up that backlash.
Loads of 3/4 5 square thread left hand taps available in the UK if you can't locate any in the USA. 👍👌
just proves what an amazing community of fellow machinists follow you, Adam. Defeat is NEVER an option!! 👊👊👊👍👍👍
You will never forget to look for a hidden pin again. That lesson will stay with you for life. This is why experience is as much an asset as education
You are right! But one good thing he did was stop smacking it (i probably may have carried on) and didnt break it£
I got a multifix from Peter and I love it! And as Adam said he was very, very helpful. What I thought I needed was wrong and he looked at my order and contacted me with his suggestions and sent me what I really needed. And for my trouble threw in an extra tool holder to boot. I highly recommend getting tool holders from him if you need one.
multifix are average at best. fine for home/hobby shop work. way better options for a proper solution out there
@@konival9753 Prove it without just parroting something you saw or heard on TH-cam.
You are showing that old machine a lot of love for all it has done and all it has left to do.
Seriously admire your knowledge and how much thought and effort you put into projects to get them how you want. Top notch stuff Adam.
I'm getting very excited hearing you talk about making tools/ tool holders.
I repaired such a crashed nut a while ago. I bored the old threads (plus 2mm) out made up a brass plug and soft soldered the it in (in place in the milling machine vise), drilled/reamed the inner diameter and cut the new thread on the lathe. it's holding up fine.
I saved a lot of machining steps this way.
Cleaning montage...very satisfying
Didn’t expect spa music, but I’m here for it
That CRC ad placement was weirdly relaxing. I had a sudden urge to grab an old IH intake manifold and start scrubbing - which is odd 'cause it's Sunday night and I'm about to fall asleep:) Nice job.
😉👍
Man... I'm glad that I'm not the only one to have that kind of experience in refurbing an old machine... paint, oil, chips, filth, etc... concealing fasters and limiting movement has absolutely been the biggest theme in my own machine tool wrenching efforts.
As for cleaning, I don't have a parts washer, but what I have found is the most effective/economical is using diesel fuel as a solvent and a green Scotchbrite pad.
NOOOOOOOOOO!!!!!I was so concentrated the 37 minutes flew by!! Cheers from Toronto!!!!
Really digging the mellow background music with the more cinematic shots!
I've been a viewer for a very long time and always enjoy the content. In a compliment to the channel, the production has moved to the next level with Abby's addition to working on it. You two make a great team.
1:57 ... Many years ago, when internet had no pictures, or video ... on a dial up e-mail forum, a member told me "The internet is ALL about the free exchange of information" ... this is a shining example of that fact,! .. This is why we are here! :)
Thanks for sharng your knowledge with us. As you mentioned others are nice enough to share their knowledge with you. It's a GREAT world we live in.
Looks as if the 'But Adam doesn't need anyone's advice' crowd has gone MIA for this episode.
I really liked the vibe of the video, nice music, editing and camera work
Glad to hear it, thanks 👍🏻
I do love watching these videos, even though I'll never do anything like this myself. There's just something very satisfying about seeing some of the machines that helped make this country given the attention they deserve and made new again.
Don't use normal 6201 ball bearings. You need the 3201 angular contact bearings to take up the thrust and backlash
You can use deep groove ball bearings as if they were angular contact provided the thrust load is not excessive, and in fact most drill presses do exactly that. It would be fine in an inexpensive import lathe, but I agree that for a lathe of this class there should be an opposing pair of angular contact bearings, either with the inner ring end-faces ground underflush (by the bearing maker) to provide the correct preload, or by careful engineering of a suitable (cylindrically ground) spacer.
Love the soothing sounds of parts washing!
Zen and the art of part washing.
The love you have for your tools and the pride you take in caring for them, is why I enjoy your channel.
Keep on keeping on. 👍 👍
I started laughing at the soft, soothing music, slow-mo scrubbing shot 😆
Same.
Tool Holder has so much mass it has its own gravity.
We just got one of those parts washers into our shop, I was initially skeptical but was very pleasantly surprised the first time I had to clean off some old pins on just how well that solution works! Just wish the tub was a little bit more heavy duty so we could put our truck hubs in there without worrying about breaking stuff!
Normally I don’t like background music in videos, especially while someone is talking, but in this case the music you picked while washing the compound made my pulse rate decrease by 20 points. And then I had to chuckle when you did slo-mo on some of the washing, it perfectly matched the relaxing music!
I don't know why, but I enjoy cleaning old grimy parts and seeing them come out clean. Nice parts washer setup.
Indeed, but it doesn´t do anything (for the home shop guy, at least) which an old laundry tub and some kerosene in a cheap and cheerful lab supplies wash bottle, and stiff bristled brush and some Scotchbrite won´t do. Kerosene is not suitable for intensive long term use in production settings, but if you´re just refurbing the odd machine tool, its perfect.
Kerosene used for parts washing can easily be retrieved and reused by settling it over water: the dirt drops out of the kero (top) layer and can be drained away and disposed of (without polluting the grey water system). It´s an easy matter to make your own parts washer incorporating this principle with a cheap marine bilge pump. Fit a drain for the semi clean kero in the side just above the level of the water, and another drain (a large diameter screw cap) at the bottom for the dirty water.
If you avoid putting oily parts into the kero it will stay relatively clean. start the process with a ¨total loss¨ stage (ie discarding the minimal amount of solvent needed to wipe off most of the oil)
ScotchBrite is a product which delivers (crudely speaking) twice the performance for a price premium of 1.2x
That orange stuff, on the other hand, turns those ratios on their head.
I deplore the turn so many You Tube influencers are taking in the direction of promoting ¨affluenza¨. It is undoubtedly good for the Gross National Product, but so are such things as war and natural disasters.
News Flash: Abom goes ASMR and gives his parts a warm, cozy bubble bath
I loved it. Made me sleepy
😁👍
Love the clear and high quality videos thank you.
I forgot to say this on the instagram post,(I saw something shiny) 😆 I love a parts drawing or parts manual at a minimum when disassembling a unfamiliar part. Sometimes they can save time and trouble on unseen things. Of course now days as we found out in this case, the internet is a wonderful resource. Pretty good bet someone has done it before you. Cheers man 🍺
I had the same exact thing when I was putting new bearings in my 18" pacemaker compound rest. Missed the taper pin too! That toolpost is ACES!
It's like ToT and My Mechanics had a love child over a huge old lathe!
I don't think either of those are old enough to have sired that machine😉👍
I have to say your videos are so relaxing to me. I enjoy the detail you go into.
That is a beast of a tool holder. Put the compound back as is but then fab a new equivalent acme screw and nut. Could also have a new nut cnc thread milled.
Agreed, replace the leadscrew with a 5tpi ACME thread and a suitable nut. There's bound to be wear in the screw anyway.
I was going to say that too....
Nice cleanup, moving along. Thanks for the look.
Another good one! Glad to see others reviving old machines. Keep up the good work!
This is so satisfying to watch. I want my own workshop so much seeing all this lol 😂
The Multifix system looks solid; its good to see that some companies are still making them.
One good thing about a machine shop, you can make replacement parts for machine tools if you need to.
😎
Indeed (picking up on your irony) that´s not the American way-- at least it no longer is, in the new ¨improved" America....
You get howled down for making stuff instead of buying it... even on machinist forums. Business doesnt have to pay to do its own marketing these days, free citizens are falling over themselves to leap into the fray.
Remake the screw with acme threads. You already need to repair the threads for the nut on the end.
That is a wonderful tool post.
Adam, You are a machinist, Correct! Make the nut and cut the threads on the lathe using a form tool. Drill and (on rectangular brass piece first) cut the threads using the 4-jaw on the lathe. Counter-balance. if you screw up, you can always whip-up another one. File the butchered corners on the cross-slide and go to Sherwin Willians and get a gallon of Industrial paint in a bright lovely color of your choice. Paint the cross-slide and all the cast iron parts. Sand and polish the handles. You can paint the bed/headstock later, Hire some kid. The Multi-fix looks great. Oh yea, cut and throw away those 2 threads on the cross slide screw. My 2 pennies!
If that's Abby doing the camera work she is doing an excellent job. 👏 👍 👌
Great tool post sales video. I did learn a bit about tearing down the compound on my 14x54 pacemaker though.
Sehr gut mach weiter so!!👍👍
Sweet! Tee nut . Thanks for sharing! Got a brass thread stuck around on the lead screw .
Did you listen to the video?
Great video, can’t wait to see the rest. The bronze nut could be one whole video by itself, hope you can find the right tooling for it.
As others have said my "starter for ten" for finding the left-hand modified square tap would be Keith Rucker as he has such an amazing collection of old tools (along with contacts for those he doesn't already have).
I have a little Atlas 12 inch. I am amazed at how big Adam’s tools are!
Wow - that is one impressive tool holder. I can't imagine the force those cutting tools must be under when in use.
Nice job on the compound clean up Adam. Boy is that D1 Multifix a big one! Makes my one for my 12" swing look puny! Can't wait to see the American Pacemaker running and making big big chips with that PWE miutifix!
Seeing that cross slide by itself makes you realise that is a lathe that “means business”👍
Nice bit of Karma there, getting tips back from the internet after uploading so many yourself👍👍
Thanks for sharing Adam, you're moving right along on the tool holder. It's looking good. Stay safe and keep up the good videos. Fred.
ABOM goes ASMR
Nice touch
Paint the cross-slide gold to match the tool holder. A gold cross slide would be funny to see in a shop.
Watching this was like meditation.
New Title Abom79 presents "More Brand New Stuff"
Thank you Adam I enjoy watching your wonderful videos and learning from you I am watching from South Africa
Nicely done Adam. Thanks for sharing this project. I’m anxious to see what projects you have in mind for the American Pacemaker.
You could (maybe) have Peter of Edge Precision in Houston make you a tap as he has shown his cnc tool grinder on YT. It would be such a excellent combination - a Manual Machinist Wizard with a CNC Machinist Wizard.
Making that bronze nut would make a great vid, Adam. I would like to see that.
Zen cleaning! I thought the face cream was coming out for a moment!
Really enjoying your channel Adam. Great quality of workmanship and great camera work and images to match.
Thanks for another informative video🤗😎🤗😎
Thanks for sharing Adam. great footage
Wow - much bigger project than first glance
Love the ASMR parts cleaning !
Now that's a TIP that saved the Project...
Abbey’s camera work = 🤜🤛
I've used this solvent tank and it really is the best ever. Mineral spirits always leaves it feeling oily. By far the best cleaning system out there not an ounce of oily feeling at all. Not getting anything from this review just a great product.
Please use the shaper to make the tee nut. Perfect tool for the job.
Love the slo-mo hand wash action 😝
Adam, you need to watch Kurtis on Cutting Edge Engineering; he makes his own boring bars, due to the size of the jobs he does. His latest one he has to use his overhead shop crane to put it into his lathe.
Always someone to mention Kurtis when Adam doesn't like him or his channel.
@@stevendupre2792 Why doesn't Adam like him or his channel?
Most likely because people are always comparing their channels to one another.
@@stevendupre2792 Kurtis challenges his "keyboard warriors" and he shows how he cuts out 6 extra steps before working on a barrel for a hydraulic cylinder so all he has to do is measure the height and length of the piece before he makes one chip.
@@MRHSDM316SD18186 I'm not sure I understand your comment. I didnt hate on Kurtis' channel or his work. If anything he's more popular than Adam is now since he's become nothing more than a TH-cam creator.
Adam, at my families machine shop we make very similar leadscrew nuts that are sold directly to monarch and leblond for there spare parts warehouses. They are not typical bearing bronze they are c954 aluminum bronze. Also we get the taps from a supplier called Widell Industries and we use our bigger mills like your new KBC to tap them. However monarch and leblond have switch to ACME threads so I don't know if Widell has square thread taps. Hope this information helps.
I think a number of us here say thank you, Dalton. That's a pretty useful lead.
Adam, I think I would make a new lead screw and nut in acme thread and eliminate the backlash in both the lead screw and nut and solve the problem of the obsolete square thread.
That’s the plan.
@@Abom79 would changing to the acme thread change how the indicator marks readout
Instead .1000 in actuality it might be .0001?
The smart wash Ozzy Juice is an amazing invention. Since it is sooo expensive the juice they claim not to add water as it dilutes it. I queried the compound and 98% of the solution does not evaporate therefore by heating it all the time the water is all that evaporates I’ve already done the expirementing it works great cuts the cost down in fact it seems to me it works better. The mats carry the microbes that eat the oil and grease and have found changing them monthly really helps keep it working great. One of my favorite tools in the shop. Im a bit older and find I feel sick if im in the solvent or diesel and have had to rely on rubber gloves. Getting old is not for wimps LOL. God Bless you brother.
Get Peter at Edge Precision to make you a square thread tap!
That's a lot of backlash in the leadscrew. Yes you can work around it, but given that you will likely be using this lathe for many years, I'd put in the time to either cut the right threads for the screw, or just make a new ACME screw and nut to replace the original ones. You have the chops to do it, and the results will be SO much nicer to use..
That's my bet on what he's gonna do
Things got weird during that slow mo rub down. Made me feel kinda funny 😅
Time for a smoke 🤣
I absolutely enjoy your videos Adam
keep up the good work.
best part of Saturdays is seeing your latest video
The videos ain’t bad but you might need better Saturdays.
Dat cleaning slow-mo was sensual.
Maybe Keith Rucker have a fitting Tap in his Collection? :-)
A man with a plan! 👍👍👍
very good information for me because I have a 20x60 American Pacemaker lathe thank you.
Oddly really liked the ambient music while you were cleaning lol
nice find on that pin
Oh lord, those bearings! I winced when you "spun" them. Those poor things deserve a good retirement. They've clearly put in more than a full lifetime of service.
LOL, yup. Sounded like I was eating grape nuts cereal!
Adam, the music while washing was getting all zen like ... Made me go off into a dentist chair trance. Only thing missing was the nitrous.
Now that's a tee nut!!!!!
another excellent video. love your work.
Adam, if you tap new thread then you might end up with loose fit because of the wear that is already in the square thread so if you tap you might want to get a undersized tap then hone out the threads.
Someone already posted that you might go to a split nut so you can adjust out the slop when needed
Here is some trivia you'll probably like. I learned machine work at place called Industrial Bearing, a bearing suply house for heavy industries like mining.
The bearing you said was "sticky" is a referred to as "staging" because it wants to stage. Its a very common failure in universal joints where the bearings have made like detents in the race surface from opporateing in the same place over time. This is the reason engines are mounted in vehicles at an an angle or the pumpkin of axles are offset to one side, forcing U-joint to move enough to use the entire race surface. So U-joints are actually required to be misaligned to function correctly.
Saw that "ND" bearing...which is a New Departure Hyatt brand, and as a PT/Bearing salesman for 44+ years, it's been at least 30-35 years since I've sold one of them!
I think every lathe used them back in the day haha. I've replaced a bucket worth.
Chris at Clickspring is the best I've ever seen for layering sound. I think it is an excellent tool for the channel. It was the first time I'd seen it on your channel. You did good!!
Great ideas...no point in short cuts on this lathe....it's too old, too wonderful, too well made to take any shortcuts with. It's still here and running, its worth putting everything back into it that it needs to be factory fresh again. And, very inexpensive to get there ! It'll be a complete joy to stand there for long periods of time and use ! She's all broken in too.
