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.
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.
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.
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.
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.
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.
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 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.
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.
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!
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!
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.
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.
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!
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! :)
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.
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.
Are you able to CNC tap the T-Nut? That seems like it would be alot easier than making a big tap for that kind or thread. I love it when grandpa's tools come into play. I got a few tools from my grandfather that I use alot, I find comfort in it being like he is helping me with what I am doing, even though we didnt get the opportunity to do it much when he was alive.
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.
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.
@@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 RUclips creator.
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!
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).
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.
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
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.
Love the fact that you are still using your grandfather's tools. He chose right ! Looking forward to seeing the next episode of this really interesting project. One question though on that screw-thread. If the Bronze bolt had play in it, will you have to check the screw-thread for similar wear, (where it looks shiny), or will it be "insignificant" ? Stu
Adam I have a pacemaker with the same compound. I just dissembled it and my bearings Were sticky like yours. Very similar condition as yours overall. My screw and nut were tight with little wear. [ACCEPT] The first three threads on the brass nut were broke off exactly as yours were. Thats too similar to be a coincidence. I'm wondering if there may be something in the design that either allows too much travel and the screw is coming out of the nut or almost coming out putting stress on the last three threads holding. I'm going to study the length of travel and see if I can figure this issue out. If you can look the length of travel in relation to the length of the screw maybe, you can figure out why this is happening. It may need a stop or spacer to prevent over travel. If you see an issue, please let me know what it is. Thanks Mike
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.
Adam, If you can't find a 3/4"-5 square tap and since there are 3/4"-5 Acme taps available you could make a whole new compound lead screw and nut with Acme threads. It won't be original but it will be do-able and work just as well as the original did when new. I believe the bevel gear on the lead screw is pressed on so you won't have to make (or source) a new one of those.
Adam, So ill bet if you start asking around you'll find that square thread tap up here around the Cleveland, Ohio area or the Great Lakes area. Some where that those 80-100 year old machines where worked in back in the day. I've shot a buddy of mine a message thats in Euclid, Ohio. He's still has his fingers in older tooling like this, So its very possible to still find a tap that you could source to make another replacement nut.
Вітання з УКРАЇНИ ,думаю мітчик можна виготовити самостійно, враховуючи нестандартне різьблення винта. Запалити та відповідним чином заточити. Для майстра це буде не складно.
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!
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.
Hey Adam, you might contact Keith Rucker. He has done this kind of thing in the past and may have the tap you need. You might be able to make an arrangement with him where you can make a new nut and then send it to him to have him cut the threads for you. If he doesn't have the tap, he may know where to find one.
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!!
I like the way that Orange-Glo looking CRC cleaner works on that cast iron. Those slow motion sudsy shots are almost hypnotic and the stuff probably smells good too.
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.
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!
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!! 👊👊👊👍👍👍

@@konival9753 Prove it without just parroting something you saw or heard on RUclips.
Seriously admire your knowledge and how much thought and effort you put into projects to get them how you want. Top notch stuff Adam.
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£

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.

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.
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!

Remake the screw with acme threads. You already need to repair the threads for the nut on the end.

Hey Adam, you might contact Keith Rucker. He has done this kind of thing in the past and may have the tap you need. You might be able to make an arrangement with him where you can make a new nut and then send it to him to have him cut the threads for you.
If he doesn't have the tap, he may know where to find one.
Adam knows Keith well. You must be new to this channel. Welcome!
You should do some braze repairs on the front edge of the compound before you do your resurfacing on it with the T nut in 😊
nice find on that pin
Seeing that cross slide by itself makes you realise that is a lathe that “means business”👍
Oddly really liked the ambient music while you were cleaning lol
New Title Abom79 presents "More Brand New Stuff"
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!!
Did Evaporust forget to send a check this month?
I like the way that Orange-Glo looking CRC cleaner works on that cast iron. Those slow motion sudsy shots are almost hypnotic and the stuff probably smells good too.
ABOM goes ASMR
Nice touch
best part of Saturdays is seeing your latest video
The videos ain’t bad but you might need better Saturdays.
Have you done a video on exactly what all the features of the multifix are, why it is so special compared to other tool posts?
Loving the content you're putting out Adam.
Watching this was like meditation.
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.
