Help With Leak Test Results

Yup, one of my goals in life is to be able to afford to call 'em and have
them ship me 6 of everything . . .

Seriously, placing an order with them is a problem, 'cause there's always
something you should have included in the order but forgot.

When you order the pinch clamps, don't forget to get a roll of UHMW
polyethylene tape. Great for anti-chafe etc. Their number is 76445A12 for
the 1" wide X .0065" X 18 yds.

I think one day I will just buy all of the bits needed to build my own
glider from these guys - it's pretty much the default source for
anything that I can imagine needing.

I also recommend getting some of their silicone tubing to connect your
instruments. I started using it when some came with my Cambridge vario a
few years ago. It is softer and more flexible the typical clear (but
often colored) plastic tubing and remains that way instead of hardening
over the years. That makes it easy to put it on the instrument, easy to
remove (just pull - no cutting required), and it doesn't need clamps to
prevent leaks.

Because the glider is plumbed in the usual clear tubing, you need to
transition from that to the silicone with a barbed fitting (straight,
tee, or cross, depending on how many things you want to connect to the
particular line). You could use a clamp on the original plastic line
tubing, but because it is never removed, I haven't had any problems with
leaks there.

It costs a bit more, but you can buy it from McMaster-Carr in short
lengths, so the price is not an issue.

My office happens to be about 30 minutes away from their East Coast
warehouse, so I've driven down there on occasion. Talk about a kid in
a candy store - yikes. My wife sees about 2 packages a month from
there between glider fiddling and household projects . She was
beginning to wonder if I'd developed some substance abuse problem, but
all I had to do was mention the glider, and she just shook her head
knowingly.

Here is a link that shows both types of clamps. The prices do look a
bit high.

The idea of using an O-ring as a seal sounds interesting. I have not
tried it, though.
