Machining a T-Nut for Compound Slide
Vložit
- čas přidán 29. 04. 2022
- In this video I will show machining a t-nut for the American Pacemaker compound slide. This type of t-nut install is what is recommended by the Original Multifix company and how PeWe Tools also recommends installing their posts as well. The purpose is to provide the base of the post full contact of the mounting surface. There will be a followup video showing the machining of the tool post bolt.

Your camera resolution is so good that when you get close to the work I get chips on my keyboard.
I hope you are wearing some safety goggles my friend.
You better make certain the chips are dry, you know how bad coolant is for a computer keyboard

Haha ...here too LOL 😂
My lap is wet. I got coolant leaking out of the charge port of my phone.
Love you’re videos. Commercials are getting out of hand.
Another great video, but I just wanted to mention how the family photo at the end never fails to make me smile. I love it. Thanks.
Great video and nice job as always.. I'm wondering if it's not better to have a little extra material removed from the top of the t-nut( very little) Perfectly flush with the compound like this maybe will work, but i think is better to have some free space beetwen the bottom of the tool post and the top of the t-nut, so when tightening the nut there is enough force applied to the fresh compound plane to prevent the tool post from moving, especially with your heavy cuts.
Look forward to the see the next phases
I wonder if Adam spoke to the toolpost manufacturer re correct method of attaching toolpost to compound, before he machined this?
You are exactly right. This way the toolpost and T-nut will be clamped together and essentially only be held by the set screws.
Man that flexarm tapps like a beast.
Another good one Adam. Set screws are a nice touch to keep the t-nut from moving, BUT, I think you should take a few thou off the top of the nut to insure the ears on the compound are “sandwiched” in compression when the tool post bolt is tightened.
That's the manufacturer suggested procedure. I guess since they made the damn thing they probably know what they're talking about.
46:50
I think I remember this being addressed in a past sns.
I love watching how razor sharp your drills are.
Today I learnt about 2 items I never knew existed. Triple fluted drill bits and go/no go thread gauges. Lovely work. Cheers!
Coming along nicely Adam. Really enjoy seeing the old Pacemaker being brought back to its splendor.
Would have probably been a good shaper project too, but it was cool to watch the K&T get some screen time.
Hey Adam, You are my Saturday 3pm favorite divertissement for many years now. looking good for the future with all your projects. Keep on going. We will be there for you.
I am just glad to see you making chips again lol.
I know you have a lot going on with the new shop so I understand.
Love watching your shows.
Abby great camera work.
Can’t believe how far you have come since I first started watching you congratulations
Awesome machinning there, enjoyed the clip and looking forward to the whole rebuild. Thanks for posting.
Great stuff Adam! You call it a T-nut, but if I understand its use it is really an insert to create a solid compound with multiple locations for the multifix.
awesome episode, as usual, love how you show the change of plans and when things go right and wrong, cheers!
I appreciate the care you take in showing these process steps. I have used your videos as a guide for some of my rebuilding tasks. Thanks!
Great work. That Multifix is huge.
Steve.
I love this content Adam. It's a pleasure watching you work. Thanks for having us in your shop.
Man the shot of the grind on that special drill bit. Incredible work (all of it)
Excellent as usual. It's amazing what you can do with the right tools!
You're a hell of a machinist, Adam.
you do such a great job Abom79, thank you for sharing 🙂
You mentioned "climb cut" at 9:25, and I had no idea what that was until 9:40 when you showed it in slo-mo. At that instant a light bulb flashed in my mind and I figured out that a climb cut is where the cutting action of the mill is going the same direction as the travel. It is not as aggressive of a cut, and probably results in a smother finish as well. And no, I have never machined in my life, and probably never will, as much as I regret never taking shop class in high school 40-plus years ago! LOVE your videos, Adam!
Climb milling is tricky and can be dangerous since the cutter tries to “climb” over the work resulting in broken cutters and spoiled work especially if attempted on heavy cuts. Unless the machine has hydraulic backlash control it’s best to only use climb milling on light finishing cuts.
All your proper tools for the job. well done Adam
I enjoy watching all your videos to the end. Even though, as you say, most people will never do this, there are always great tips and ideas that can be used on other projects. Keep up the great videos!
Some epic metal mowing! Like the curly chips on the side!
Beautiful workmanship Adam pleasure to watch .
Great shot of that "funnel chip" forming on the side of the piece....love that aesthetic! I also like the striated finish that milling tool leaves on the piece
Boy, do I love it when you make stuff. Keep going sir.
That power tapping machine is nothing short of incredible!
Looks great on that size compound. Perfect proportions. Nice work.
I will second that!
I’ll third that. A beast of a tool post for a beast of a lathe.
Good work Adam. I look forward to the post bolt and lead screw videos!
That is one hella honkin' MultiFix holder! Looks great on that cross slide. Can't wait to see her makin' chips!
Your amazing you make it appear to be so easy ,thanks for sharing the story.
Enjoying it here in Minnesota...
51min was good for me🤷🙂 I enjoy seeing all the details…..thank you Adam
Always enjoy watching your content, Adam. Thank you!
These videos are not only interesting to watch but highly informative if someone is planning to buy a used machine tool.
Love the machining videos; looking forward to the next one.
Wow. That flex arm makes tapping look like child's play. Amazing machine! Respect from Texas
Seeing you tap those giant threads with authority! It's crazy watching and learning from a "garage diy" perspective. I've broken many cheap taps being gentle. Made in USA and doing it right is the way to go. Thanks, love the channel 👍👍
Right-on Adam! Getting there!
Hey Abom, just wanted to say I love your videos and I can always learn something from them and apply it to my own job as a welder/fabricator. Love the content you put out here for us! Keep up the hard work! Also, loving the adventures channel too! You and Abby are great fun on the camera!
Your predecessors would be proud of you care and diligence, nice work. it's great to bring a great machine back to it's former days. You also add integrity to your craft.
looking forward to the rest of your series on this! 👍👍👊👊
Great project - looking forward to the next steps...
Great work Adam! I am enjoying this rebuild. Thanks for all the great videos
Great video Adam! Love your shop and all those marvelous tools!
I keep saying it, Adam you're a master crafter with all metals and machines 👍🏻... greetings to Abby from us...
Nice job. We shared this video on our homemade tools forum this week 😎
Excellent video today mate, thanks for uploading.
I have used Cleveland drills and taps for over 40 years and do like them.
Love those fine pitch roughing or ripper cutters, I use them in 6 mm to 12 mm diameter, brilliant for smaller milling machines. Powder Metallurgy type are a great step up from HSS, not as rigid or liable to break as solid carbide.
Great job as per usual Adam.
Thanks for sharing.
Nice looking t-nut thanks for sharing
Nice work. I see something I'd like to integrate on my home brew tool post, to make it easier to use ... another thing to add to the (growing) list of small improvements.
You make such good videos with different camera angles, good lighting, good sound, even have a silent partner camera operator for roving camera views. Also have very good sound for clear dialog. The editing is also well done and makes the story move along at the right pace. These videos should be shown in regional technical schools for machinists, that is, if those kind of schools still exist.
Nice job Adam as usual, also kudos for the camera work by Abby
ADAM, LOOKS GREAT, GREAT VIDEO...
that flexarm continues to amaze.
I'm always astounded by the wealth of knowledge your comment section has.
That Really nice paw paw 🐾 when all put together.... looks awesome also.....
👍👍👏👏👍👍 Thanks for sharing Adam, have a nice weekend
You are a true professional! You keep your shop really clean and also your machines and tools. Your machinist skill is outstanding. It´s a real pleasure to see you work!! Thank you Adam!
Easy to keep things clean when they're not being used 🤣
@@carld7580 cry more. You boys are so jealous that he doesn't need to be slaving away in his shop. I LOVE IT. Your so bad that you need to punch a time card while he gets to do whatever he wants. You're jealousy makes me so happy it's indescribable.
Magnet Protip for you. Cut a plastic screw top soda bottle and heat shrink it to your cutting oil can magnet. It will be easier to keep the chips off of the magnet.
Hello Adam, again a very nice video. It is very important that the tap is thoroughly cleaned when tapping. I've already destroyed several threads. Otherwise, such a compensating feed is a nice thing. We have installed it on all our machines. However, for smaller threads we use collet chucks with a 4-point. It is more precise but also more dangerous. Greetings Paul
I always enjoy your videos Adam, and this one is no exception. Thank you for all your informative, educational, and entertaining videos. And, please say HI, to Abby from me.
Hello James 👋🏻
Fairly obvious that this build is "precision" and has to be done just right. Good design and a great looking tool holder IMO.
It is so much fun to see you restore this magnificent tool. I know that dead blow hammers were well known in 1970 because I worked in a GM factory that year and the Die Makers used them when they repaired my machine. They had a selection of lead, plastic, and leather, each kind in several weights. They had to be so careful of those dies, which were hugely expensive, and which bent parts with precision, particularly the hole punches. The point is that I have trouble conceiving a machinist hitting that compound with an actual hammer. How did they become skilled enough to operate the American Pacemaker lathe and yet they hit it with a hammer.
Looks Good Adam, very precise 👍.
I ended up making my t nut with a hacksaw and a file not as good of a fit as yours but it works!
PeWe Tools multifix is just awesome, In the 1980s i had original multifix ..i now ave PeWe multifix on my new machines s every bit as good and afordable plus i can use my old original multifix holders
Man that flex arm has some torque!!
that flex arm has some torque!
That one chip on the near side of the bottom pass could very well be chip of the month.
I can see that you are going to have to get another Flex Arm for the new shop. Once you one of those you never go back!
Wow that tap is awesome.
Nice Projekt Adam!
Great job 👍 Adam
Lots of handwork.Thank you.
Woow what an awesome tapping machine!!!
Nice job Adam
That band saw gives an amazing finish
Always fascinating. Thank you.
From the title.... I was not really interested in watching this video....! But I did watch it... and it was one of your better videos...! I think the fact that is was a longer than normal, and not chopped into segments was good.... Keep up the good work!!!
Great work as always!
Glad see chips flying, we where kinda afraid you had forgotten with all the new stuff, also seen folks asking where you'd gotten money 💰 💰 to buy all new stuff, in our view, it's none of their business! You do what you do and sling chipss!!! That is why people watch, not the new toys & such, but for the content that brought us (and all your long time subscribers)!
Great Video, informative, and enjoyable to watch. Now i wish i actually had a lathe.
What can anyone say…. You are the Master!
I'm not sure I agree with the toolpost clamping method used here. Seems to me that the top of the nut should not contact the bottom of the tool post. There is only a few small pressure points locking this in position. IMO I think you should remove .010" off the top of the nut.
But it is your lathe, you do you!
Thanks for taking us along.
My thoughts exactly
@@rroberts383 A few comments along these lines. I hope he takes notice and reclarifies.
I wonder if Adam spoke to the toolpost manufacturer re correct method of attaching toolpost to compound, before he machined this?
I agree. I believe Adam is concerned with rigidity. Removing the material as you suggest would actually increase clamping strength. Adam is essentially removing the T-nut and slot. Why?? It's his machine. Let's watch
As long as it's not sticking up above it shouldn't be a problem but saying that if it was me I'd be leaving clearance.. i just don't think there's really anything to be gained by making the t nut flush but i guess we'll find out soon enough.. i recently put a quick change tool post on my little lathe and i left clearance and rigidity certainly isn't a problem on that machine, the 1hp motor is overloaded long before rigidity is a problem.. my big lathe doesn't have a t slot and it's no more rigid than other lathes that size that do have a t slot
Love your channel's awesome tools.
Great video abomb!
Excellent episode!
As an engineer turned software engineer decades ago, I very much appreciate your precise honed methodology, your attention to detail and your thoroughness. You make beautifully engineered pieces. The summer I worked in a machine shop during a summer internship in college makes me appreciate just how skilled you are.
On a different note, I have been enjoying your channel for a few years now and I would like to command you on your style: You let your technique, the tools and the materials speak for themselves.
Thanks for posting some machining videos…..was happy to see something other than new tool tuesdays….good stuff
Very nice work!
always a pleasure to watch
That looks really good
1018 steel? Never found a way to get a good looking finish on that stuff with a shellmill. Smooth? Yes. Looking good? Not. That tool post is a monster! 1/8" DOC and full radial? That machine got some power! Carbide rules bro!
Looks great Adam, going to work really nice when all done, thanks for sharing with us. Fred.
That big cutter is hard core. Gets it dun.
