44-100?

Kurt,

I followed exactly what you are saying. That is why I was suggesting about a spring loaded center. There is such a small amount to take out of the chamber that you want to be able to support the reamer so that it cuts concentrically without gouging in, or having excessive pressure so it cuts too deep. A lightly loaded dead center (or live for that matter) would help you support the rear of the reamer while you are probably turning the reamer by hand?

It is also why I suggested making a test chamber to try the new reamer on.

Unfortunately I see you sent the reamer back. If you could have made a test chamber to try it on first, you would know how fast or slow it was going to cut, what is the best cutting fluid to use etc.

Or are you going to have someone else do the rechambering for you since you are still messing with your lathe ?
