A few years ago we made some Wiggins couplings for water plumbing.
These are widely used in airliners and military aircraft as well as Formula
1 race cars. They are highly reliable, long lasting  and quick to take
apart. They must be tig welded to aluminum tube. If you buy the race car
versions they are about $100 each. We simplified them by doing away with the
outer trick clamp and used a mundane hose clamp instead. We also standardize
on 1.5 inch OD aluminum tubing for water plumbing. That would be the only
size we would make.

We are thinking of making another batch but we would need to make at least
50 sets. Is anybody interesting in buying some of these? My guess is they
would be half the price or about $50 a set.

Paul,
I will take six.

OK it looks like we are getting some interest. I know Mark Steitle wants some more as I think he is re-doing his ES installation with a 3 rotor p-port.
