I find if I use a soft substance for the seal, the work will move and that
acutally causes more trouble - the seal made from hot melt will leak a
little, but not too much if the object is pretty round, and the vac will
suck it into place - if it slips, the hot melt heats up and glues it in
place, and if it really leaks, I put a little bit of a plastic bag over the
leak.

don't buy from a woodworker's catalog. try any of the following:

1. use the Soren Berger method - build up the lip with hot melt glue,
shape with your gouge into a smooth curve - this is what I use on cup
type vac chucks and I like it a lot.

Does it stay soft enough to seal after the first day?

2. go to salvation army (or whatever) and get an old wet suit - the
closed cell wet suit material is great for a flat plate type chuck, you
get a good seal and it's very durable.

The only wet suits in this part of the world is what you get at a rainy
funeral.


I think I've got this stuff covered in my article on the subject - of
course I haven't read it since I wrote it a few years ago and hte memory
grows dim - you can DL the article from my web (www.wbnoble.com) under
vac pumps, or you can get it in the tips section of www.woodturners.org

Thanks again. I read it.
