[QUOTE="specweldtom, post: 398854, member: 2580"] bigngreen, the pusher holder JE Custom mentioned is made and sold by RockJag4 on the 6mmBR (Accurate Shooter) website. I have one of them, and have a 6.5 x .284 chamber to test it on. It appears to have minimal radial float, but looks like it will be very easy to use, and as Fitch said, will give good "feel" on the reamer. I've used a Clymer floating holder, but it doesn't let you feel the reamer torque, so I want to try something that does. In my opinion, the place to start is to get the tailstock quill as perfectly aligned as possible, no matter which holder you use. Mine took 3 sessions (many hours), but is parallel and axial to .0005 in 12". It is .002" high until I clamp it hard on the ways, then that is where the .0005" comes from. I move the tailstock back and forth several times, wiping the ways dry before clamping it down, but it is still .0005" high. I can't consistently work any closer than that anyway, so I drilled, reamed, and installed two # 7 taper pins to lock in lateral location of the base to body joint. So if I need to kick the tailstock off, I should be able to return it to the alignment I have now. I hope. I can't comment on using the carriage/toolholder to hold the reamer. Thought of it, but decided to go with aligning the tailstock instead. Good move for about 100 reasons. Take a look at RockJag's holder. Simple and well made. Tom [/QUOTE]
