Anyone have good pointers to where I can get a 6" scroll chuck with an

it is sweet being able to dial in concentricity. I'm trying to find the

good chuck.

Buck is the name brand. Bison has them too. I happen to know a cheap
skate that just made his own, Not that hard a job.

Personally if I were to buy a new chuck I would just buy one that has
removable top jaws--be careful truing your backplate and it should run
within a thou or so which is fine for most work, that way if you have a need
to be dead nuts you can always put in a set of soft jaws and bore them.

Yes, you can.

Besides, adjust tru chucks take will vibrate quite a bit unless you have the
chuck body running close to centerline and they take just about as long to
dial in as a 4 jaw which negates much of their supposed advantage anyways.

Except for repeated workpieces of the same diameter. Tune it
once, and you are fine through a number of workpieces.

I'm GWE on you getting ability to own a suppressor. Done deal from
what I've read. We're still just like the People's Republic of
Kalifornia in regard to suppressors here in MN.

They are legal here where I'm at but I fail to see any legimate purpose for
them especially considering that the attendant permitting fee is ~$300.00...

I also fail to see a need for them here. I'm not even sure
whether Virginia allows them or not, and I have no motivation to check.

If they were not so expensive to legally own, I might be
interested in making one or two to see how they work -- and how well
they might be made to work -- but after that I would not see any reason
to keep them once the experiment was done.

Enjoy,
