In the last two weeks I saw a 12 x12 sheet of gasket material in some
woodworking catalog, but now I cannot find it anywhere. Anyone remember
seeing such stuff? This has been a senior day.

Go to Walmart craft department. Buy a Foamie, it is closed cell foam.
About one $ a sheet.

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.
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.

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

Hello Gerald,

I am using 1/16" Duro40 Buna-N (Nitrile) rubber sheet bought from an
industrial supplier. It comes in 3' widths, so I have a bit extra.

Works for me, although the rim needs to be fairly even. I chose the
thinner material for stability although thicker material can be bought
and used for more uneven rims. It has proven to be resistant to
lacquer, sanding, tearing, and is fairly resilient. Seals very well.
(Off-center 1 lb can at 15" and 800RPM - 2.7mb video)
http://webpages.charter.net/videodoc...umChuck05l.mpg

Since you're somewhere in Georgia (I'm in ATL), if you can't find
something better, I could cut off a piece and swap it for a wood blank
or something - or send it to you for cost/shipping via USPS.

FWIW

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

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

Thanks, Greg. But if you are down this way anytime soon, I'll give you a
spalted sweetgum blank, already roughed out.

Don't get down that way much since my sisters moved from Macon, and
Redstone Arsenal proved to be better pickings than Warner Robins AFB
when picking up Military test equipment.
No plans to go back to Florida anytime soon, either. Used to contract
work to Dawson Mathis's brother in Julington Creek, FL, but, according
to the woman I visited with this April, he died last year.
So... excuse the rambling.

I've been very happy with this:

http://www.woodturnerscatalog.com/cg...n&key=314-1011

I bought 2 sheets and they will make several gaskets..

I tried foam, mouse pads, etc.... even plumbing gaskets, seals and o-rings....
this is the only thing that really worked well for me... YMWV

I have very good luck with weatherstripping foam, which comes in rolls with
an adhesive back.

Thanks! That's the place. Maybe I found it online since I don't get
their catalog.

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.

For sure.... I tried packing foam first..
It sealed ok, but if you put a little pressure on the bowl, it would move...
sort of a weird feeling..


The stuff from Craft Supplies is like a thin mouse pad without the slick side...
seems to seal well and compress enough under vacuum to not have that movement..


The hot melt didn't work for me, but I'm not a hot melt user normally and it
does take a certain skill/experience level to get a uniform bead..

I used silicon sealer for a while and it was ok, but had to be reapplied every
few bowls..

It's all your fault, anyway, Bill...
You got me hooked on this vacuum thing.. *g*

At 3/8", I'd think that would be a bit too thick. (3/8"x16"x16", $12.50)

I ordered a sheet of this 1/16"x18"x21", $7.25 stuff:
http://www.aftosa.com/neos.html
a few weeks ago and am very pleased with it. The stickum is tenacious!
(I've ordered from Aftosa several times and have been pleased with every
order - and I've yet to find a more economically priced beveled mirror
supplier.)

Tips fer Turnin': Place a sign, easily seen as you switch on your lathe, warning you to remove any and all rings from your fingers. Called degloving, extended hardware can grab your ring and rip it off your finger. A pic for the strong of stomach: www.itim.nsw.gov.au/go/objectid/2A3AC703-1321-1C29-70B067DC88E16BFC/index.cfm

Besides, rings can easily mar the surface of a turning as you check for finished smoothness.

I used Buna-N (Nitrile) rather than neoprene, for its resistance to
abrasion and chemicals. 3' x3' x 1/8" sheet of Duro40 for about $20.
Works pretty well, soft "sticky" surface, and keeps the workpiece
stable. It recovers from indentation well, and as long as the rim is
reasonably flat, grips tenaciously. For more flawed rims, thicker
material could be used.

http://www1.mscdirect.com/CGI/NNSRIT?PMAKA=31935117

It is not self-adhesive, however. Not really a problem AFAIK.
They do sell adhesive versions - at a price.

Neoprene, due to its lower tensile strength, could be considered by
some a safety factor against catching on the material should you
decide to cut close to the mounting point.

In the end, any material that works is better than no vacuum chuck.
