Good Easter Morning all; In the process of making these tap hats, I've bored an alu block, which when a saw cut is run lengthwise, will grip the brass slugs for machining them here and there by gripping them in an agile vise.
But the thought has come to mind that for series production, I also need a jig to hold these R8's when they arrive in order to cut the slot in one leaf of 3 leaf design, to make that cut in the lip for the keying screw. I see a lot of similar gizmo's for 5C tooling, but haven't tripped over one made to do the same thing to an R8. Seems to me if its handy for a 5C, it ought to be equally useful in the R8 world. Basically it needs to clamp to a mill table, holding the R8 horizontally solid, at a rotation angle locked by the R8's exterior key slot, but with perhaps 3/8" (most of the taper) sticking out so this key pocket can be machined into it, say with a 6mm SC endmill, maybe even smaller since I've decided a 4mm bolt s/b plenty strong enough for that. If I do this machining close enough, there shouldn't be much sheer force at the bottom of the bolt head because the head will be engaging both the brass slug and the edge of the cutaway in the R8. Do any of you have such a critter & what's it called? Or do I need to make it? FWIW, that ER40 kit works very well in the remachined spindle bore of this Sheldon, maybe a thou TIR. I made 26 of these slugs in about 2 hours yesterday, out of 1, 36" piece of brass rod, and I bought 2. So I've brass enough to make 26 more. I probably spent more time hunting around for a pusher ram to eject the next 1.25" of rod than I did machining with a cutoff tool. Thanks all. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
