tail stock chuck on the lathe)

these babies will make you wish "you'd ate your wheaties") 8-)

in #8257 where Bucky

floating reamer holder both on the net and in whatever books I can find, and
For the record, a floating reamer holder is one that can drive a reamer as

both angular and concentric alignment.
This is desirable for all reaming, and mandatory for accurate firearms
chamber reaming. Unless you are the sort of gent who can hand-ream a .308
chamber, in which case I apologize.
Commercial floating reamer holders are rare and expensive, and design
drawings are even scarcer, AFAIK.

Thanks for your prompt reply. I believe the posting was for a
'floating reamer holder' for general reaming. I may have made a
mistake in linking you to this post, perhaps somebody ele in the group
Better yet, what does everybody do to hold reamers in use, besides

chambers in rifle barrels. The way Master Spann taught us to do them at CST
was to first set up the barrel blank between centers, with a dog and
driving plate at the headstock. Then, the breech end was held in a steady
rest, the thread detail was machined, and the chamber was cut using a
reamer held with a T-handle and a dead center in the tailstock.
Always worked for me, and the groups have been spectacular!

Things would be much different if you chucked the reamer in the
tailstock and used it that way.

years, but never really thought about what it was called.
Another application is a small dead center in the spindle on a Bridgeport,
useful when tapping small blind holes with a T-handle tap wrench.
So, what's with this "floating reamer holder"? When I find out what it is,
do you suppose I'll wonder how I ever got along without one for the last 20
- Technically, using the reamer holder by hand is a floating holder while
putting it against the tailstock center really isn't. A minor point but one
for when you start working a reamer it does matter.
Also, you should minimize the side forces on a reamer when you put it into
the hole as this will oval the hole out a bit.
