Attention turners: I'm new to turning and have experienced two bowls

close to me (whew) but one almost put a ding in the ragtop that shares
my shop.

I've been looking for longer stops that are a bit wider at the outer
end, to no avail. Any suggestions?

You can get some longer screws from Lowes (Metric, I think) and some
rubber tubing. I had the same thing happen to me. Was finishing the
bottom. I think it partially came loose and caught between the cole
jaws and the tool rest and the jaw stops just threw it. It hit the
ceiling, then the far wall, came back and hit the top of the table saw
and landed at my feet.

I call that a poor man's stress test. That's when I switched to a
vacuum chuck for reversing bowls. NEVER had one come off the vacuum
chuck.


Keep an eye out at

for a Gast vacuum pump (I got a 230v 1/4horse model for $83). Then get a 6"
faceplate from Harbor Frieght

Item "M3", a 24" length of brakeline tubing (small enough to fit the
knockout of your headstock and a length of vacuum tubing, and a circle of
3/4" MDF and a sheet of 1/8" cork. For around $100, you can have a vacuum
chuck and not have to worry about things coming out of your Cole jaws.

FWIW
