Machining the Beauty Ring Fixture for Op. 2- American Pacemaker Lathe

I love the clunky sound of the pacemaker running. It's not broken. that's just the wonderful sound of old machinery.

Adam, I would give my right leg for those magnetic clamps for plate work. We typically have our fixture plate stock Blanchard ground so we know things are flat and parallel. If we had those clamps, we might get away with not having to do that. May I suggest, while you are sucked down from the bottom and well supported, you take a little time to profile the outside edges. That way you have all those features done in one setup, and if you ever have to indicate the plate on the table, you have four straight edges to align to. Also, when making those features, I would indicate off the Center of the stock, not the left back corner.

[@marley589]

A straight machined edge will be needed to orientate the plate to align the radial holes on both plates

The stream of coolant left of the spindle at 48:14 might be from the leakage line of your rotary union for your through-spindle coolant. Might want someone to look into that.

The flap wheel grinding is a lot less likely to affect the function of the machine than using the jaws to remove the same metal as you move the tool into the workpiece!.

Or advance the compound so the tool is nearer the chuck, or a boring bar. Less rigid, but time does not seem to be an issue. No abrasive grit on the precision bedways too.

Hey Adam I've been watching your channel for about 3 years now. I worked in a machine shop when I was a teenager. As a grunt. That experience got me interested in machining. However, I didn't follow up on it at the time. I was a heavy equipment technician for the past 18 years. When I turned 40, my back had other ideas. I decided to go back to school for machining. I start September 2025. I keep adding to my school tooling list with tooling you use in your videos. I'm like hey that's cool. I want one. Keep up the great work.

[@kevinmartin7760]

Will each workpiece be chamfered on the back of the large central hole before moving to the second station? The fixture, as made, will have a small radius where the central register meets the flat face and if the work is not chamfered this will not clamp down properly, or, if the clamp bolts are overtightened, it will be difficult to remove the finished workpiece.

[@marley589]

Yes there should be relief at the corner, standard fixture practice. Better still add a hole in the center of the first fixture to clear it and also pop the tapped holes in it to only use one fixture.

[@miken3260]

If the finish isn’t good on the Flex CNC, would you still use it to make a rough cut and just do the finish cuts on the lathe?

[@tates11]

The 4 tapped holes in the square plate look suspiciously like they could also be used to locate a plasma cut blank with the clamp studs. ( no round recess required ). The 6 clearance holes look suspiciously like they could be tapped to hold the part once the bore is finished, just like the ones he is about to machine in the round disc..

the way the cnc rapids to the next hole is nerve racking. you have to have your clearance set above any surface or clamp to be safe. is that a fusion 360 thing or the flexmill processing it that way?

[@KeithDDowning]

CNC usually uses 45 degree dog legs to get where it's going in rapid. There may be some parameters that can be set in the Flex CNC to change that. Yes, it can be scary. It's bit me before. Good practice to make sure you are always moving up in Z first, then in X & Y. Always make sure your rapids happen well above your part and fixtures.

[@CothranMike]

@@KeithDDowning before there were CAM programs us manual programmers created a fixture avoidance area called a ceiling to go to before any translations in X & Y. We called it the Z ceiling. Reclamping zones were called 'gotchas' and crashing tools into part, fixtures, etc., was all too common with the newbies. This was when the machines were 4 bit and the paper tape was measured in miles, and the number of reels per job might exceed 6-10. But it was not like we were making rocket parts or anything, oh, wait we were here in the North Alabama area. Mostly milspec rather than NASA, but that group was also in the mix from time to time.

[@MechanicalAdvantage]

@@KeithDDowning That is very dependent on the controller. In this case, all moves happen with the tool retracting in Z first and then moving in X, Y.

First fixture locates off the OD, Second locates off the ID. The first fixture has a clearance zone so the center of the aluminum can be milled out.

[@tates11]

So is everyone else. Once the bore details are finished, clamp it down with the 6 bolts and then remove the clamps. It is already set at zero. If the center of the first fixture was removed and machined slightlly larger than the finished part bore all the crap will fall through. There won't be a bowl created full of chips being recut.

@@tates11 Bolting it down won’t center it. The clearance holes are bigger than the fasteners so simply bolting the part to the fixture won’t make it centered.

[@lynnplestid2711]

Why did your spotting drill flex upwards when it started on the plate.

[@CothranMike]

Well, all lathes force tailstock tooling to find the true center of the material, all things being equal. This flex can be due to tool dogleg, not in this case, it can be due to the surface being slanted, again not in this case, or, and most commonly, the spindle droops in the tailstock due to over usage and lack of service. Edited to add: What must be done to correct droop here in this circumstance. If it was horizontal, this means in X or the direction the crossslide moves (not the direction the carriage moves, that is Z), then what must be done, and what if it was diagonal? Just a little conversation starter folks. Edited to add a bit of wording for clarification of what direction zed is.

They help with success in the clamping of the jaws, if made correctly, they help with removing and reversing the jaws, and you can't tell me they are not CUTE as a button. If you make two of them four jaw centering is a lot easier. They will require practice though, usage of both hands and some auxiliary support mounted on the ways or carriage to keep the part in the chuck until you acquire the skillz, amazing fact here... work can be fun.

Why wasn't that fixture made on the Flex? It would've been much faster because there is no need to spend time bumping it into place so it's centered on the lathe. Just lock it down on the magnets as it is now and then face mill it. Done and done. The lathe made the job much longer and harder.

[@seabreezecoffeeroasters7994]

In part because if you pull a raw plate down magnetically it will move flatter/bow (plate is not ever really flat) so when you release it any face cut you have made on one side will no longer be flat. The face off the lathe and hole gets you flat and a defined center for the second side.

[@snappingbear]

@@seabreezecoffeeroasters7994 I very much doubt you will deflect that round plate given it's thickness and small dimension especially with three magnets holding it. Also the surface of the magnets and the Flex's bed are machined to much higher tolerances that that old lathe chuck. They are flat. The difference in flatness from what you suggest will be barely measurable if at all and irrelevant given the tolerances he is maching to. If anything the Flex would produce a flatter surface. Moreover, he already used the Flex to surface the square feature. Using the Flex was the best way to machine both fixtures. The lathe was a waste of time.
