Machining a T-Nut for Compound Slide

[@clydecessna737]

Your camera resolution is so good that when you get close to the work I get chips on my keyboard.

[@elluisito000]

I hope you are wearing some safety goggles my friend.

[@mfc4591]

You better make certain the chips are dry, you know how bad coolant is for a computer keyboard

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.

[@BrianEltherington]

Coming along nicely Adam. Really enjoy seeing the old Pacemaker being brought back to its splendor.

[@nickhale117]

I love watching how razor sharp your drills are.

[@msheaver]

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!

[@ellieprice363]

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.

[@reinierwelgemoed8171]

Man that flexarm tapps like a beast.

[@machiningandtuning]

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

[@bobhudson6659]

I wonder if Adam spoke to the toolpost manufacturer re correct method of attaching toolpost to compound, before he machined this?

[@schwarzarne]

You are exactly right. This way the toolpost and T-nut will be clamped together and essentially only be held by the set screws.

[@alanhumberstone9989]

Can’t believe how far you have come since I first started watching you congratulations

[@ronnydowdy7432]

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.

[@lerkzor]

I love this content Adam. It's a pleasure watching you work. Thanks for having us in your shop.

[@macsmachine]

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.

[@Jeremy-iv9bc]

That's the manufacturer suggested procedure. I guess since they made the damn thing they probably know what they're talking about.

[@elicallaway342]

I'm always astounded by the wealth of knowledge your comment section has.

[@AllenCavedo]

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.

[@christopheblanchi4777]

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.

Beautiful workmanship Adam pleasure to watch .

[@t.d.mich.7064]

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.

[@rroberts383]

My thoughts exactly

[@arfonjones7188]

@@rroberts383 A few comments along these lines. I hope he takes notice and reclarifies.

[@bobhudson6659]

I wonder if Adam spoke to the toolpost manufacturer re correct method of attaching toolpost to compound, before he machined this?

[@metabadger]

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

[@markshort9098]

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

Nice job Adam as usual, also kudos for the camera work by Abby

[@tomoakhill8825]

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.

[@SupremeRuleroftheWorld]

that flexarm continues to amaze.

[@billmckillip1561]

[@cyclingbutterbean]

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!

[@brandenpatterson2776]

I ended up making my t nut with a hacksaw and a file not as good of a fit as yours but it works!

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!!!

[@mdouglaswray]

That big cutter is hard core. Gets it dun.

[@kirkpennock2997]

Should the T nut top face be lower than the tool post top face so the nut has the crush clearance to pull your tool post down to the tool post and pull the t nut up tight? Thanks for the video.

[@marksworkshop8724]

Very nice machining work. Like others have said, the T-nut has to be slightly below the surface of the cross-slide otherwise the clamping foce is just between the nut and the toolpost.

[@alfonse4595]

That is the whole point. Multifix tool post is a German invention. European lathes do not have a t slot in the top slide, just a threaded hole in solid metal. Aloris style works fine with a big slot missing under it because it's a big square block. But if he mounted the multifix over that big slot, just the tips of the circular contact area probably only like 25% would actually be touching and most of the base would be touching nothing above the slot. The thing he made in this video is not really a t nut, more like a filler piece to adapt the American style top slide for a European style tool post to have enough contact area.

[@dave4gee]

I suggest you mark (stamp?) the ends of the T-Nut, I=inside and O=outside so that it is re-inserted the same way each time .

[@oldmelodie1003]

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

[@bostedtap8399]

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.

[@Hey_Its_That_Guy]

[@TomTalley]

You inspired me to get my 60" end mill out for the 930M. Cut speed is about 1.3 Ac per hour. John Deere is proud of that puppy, too. But you can sharpen the 3 inserts with a grinder. ;-).. Loved your video.

[@BKD70]

Is that an end mill, or a fly cutter, or a face mill. I would consider it more of a face mill or fly cutter. I've got one too, It's a 72". But the power unit is red, the tool is orange. ;-)

[@TomTalley]

Yep, probably a fly cutter. Good catch, thanks.

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)!

[@tedsaylor6016]

I've had the spiral flute bind up a bit and it produced a loose hole. My theory is that when you torque the spiral flute the torque "un-spirals" it which causes it to grow in diameter and cut deeper threads. I guess "digging in" would be another way to put it. Either way the tap cuts deeper than it should.

[@richie4540]

That band saw gives an amazing finish

[@BaldSasquatch]

Looking great. I like when you show the small detail steps like deburring the tapped holes, with nothing but live audio. There's always a sound that tells you it's cutting right or not. Great to hear someone performing a step, that knows what they are doing, so I know when I'm screwing it up. (ha!) Do you ever put anything in the set screw holes to keep them from building up crud over the years? I was thinking something oil based like a electricians putty that doesn't harden, or Permatex non-hardening #2 sealer.

[@jbkbrand]

Adam, would you explain for the KZbin world even for the hobbyist when to use coolant vs cutting oil vs nothing? I’m 64, retired and at the hobby level now but the principal doesn’t change. You are a very good teacher so for me I would very much like to get you input. Thanks and hi from Texas

[@floridaflywheelersantiquee7578]

Nice looking t-nut thanks for sharing

[@timsullivan8708]

shouldn't the T-nut be slightly lower than the top of the cross slide ?

[@infoanorexic]

read the description, it's explained there

[@Jeremy-iv9bc]

No

[@an2thea514]

The Multifix bites into the Top Slide, if that nut was lower, we would have less engagement on about 40% of the face, which leads to less rigidness. I'd think reading up on how much steel of this size could deform and grinding it to that njmber would work, too

I'm not a machinist by any means but I enjoy your videos, very informative! I'm curious why do some machines require oil sprayed on them while they are running and others don't. Sometime you use oil while using the lathe and other times not.

[@stewkingjr]

Likewise not a machinist and I've always wondered that too. Even further, are there vent hoods above the machines? I can't imagine breathing the fumes is very healthy.

Welcome back to the machine hop. I was starting to think you forgot what got you here.

[@Joe___R]

Even though machine coolant is water based they generally have a rust inhibitor in the mix. That being said it isn't a bad idea to always clean and apply a coat of rust inhibiting oil to your machines after you use then. I prefer Starrett M1 but CRC should work as well.
