Its being difficult due to short life of the carbide inserts I am turning it with, and I should have contoured it offcenter like Andy did. I get about 20mm down the cyclinder and the end of the workpiece starts gnawing on it. I may have to make a t-slot bar so I can mount it on the mill & see how far I can get, carving it in an offcenter cone. So no progress today. I did get started on the apron though, getting the edges cleaned up and fairly square, then did a cutout to clear the crossfeed at its max out position, and drilled 8 ea .244" holes for 1/4" USS grade 8 bolts as I will be putting 4 on each side of the clearance cutout to bolt it to the front face of the saddle. I'll drill the same pattern in another piece of alu tomorrow, but with the correct sized tap drill for 1/4x20 threads. I'll superglue it to the face of the saddle & see if I can hold the drill straight enough to both drill the holes to be tapped, and tap the holes once I knock the pattern loose again, or maybe even tap right thru the first 1/2" of alu. I am looking for a piece of 1/8" hard alu to make the motor mount itself, drilling it for both nema 23 and nema 34 motors in case the 23 isn't stout enough. Future think? Me? I probably should log that. While at TSC this evening picking up a small bag of grade 8 bolts and some 6mm flat washers to fill those holes with, I tripped over a tube of permatex metal filler that looked like it was powdered alu for filler & color, which I will plug all the old holes with in this plate of 1/2", and a rattle can of darker grey tractor paint, so I might be able to make it look moderately professional. We shall see. Plum brown would have been a better color match against that antique saddle, but none of that jumped off the shelf into my hand. :( The varic has arrived, or a box of bricks, as I haven't opened the box to verify, yet... As has that pair of 50 amp 1kv bridges, and I trucked that huge toroid out to start getting all that in one pile, while telling my back to STHU, so all I need now is that 1kw induction heater module to get started on that. Found a couple heat sinks too. Progress, but not too hastily. I have a polo shirt with a sign on it. "don't rush me, I get paid by the hour", seems to fit me these days. I should have bought a dozen so I could use them as a uniform shirt. :) Cheers everybody, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
