Its been around 4 years since I first met the TTS tool holders, and this thread is, I believe, the first mention of this. I have about a rack and a half of R8's, all of which are a bit convex. I also have a couple rotary tables with chucks mounted, and a 4.5" CBN cup, so fixing this will take little but lots of time and a round tuit. There is no hope of tramming the g0704 unless one wants to spend days fitting shim stock as the post leans forward about a degree, maybe more. Another demonstration of TANSTAAFL as applied to an $1189 machine. And yes, its solidly mounted to the bed casting, with all 4 12mm bolts about 1/8th turn from broke. Just crooked enough to notice when a drill bit in a chuck is mounted facing up in order to drill the taps socket hole well centered in a 7/8" diameter brass tap hat mounted face down in a 7/8" R8. Thanks Ken. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
