After reading the DIY info on noseclips and liquid goggles, I ordered a lens and set to making a stand off / holder for the lens. When I completed all of that it was friday, and as I went diving today (Saturday) I was trying to tackle the nose clip problem at the last minute. I walked around home depot for a few hours thinking and picking up things, trying things out, etc. I thought about a c-clamp, and probably would have stuck with that, but I found something better.
It is called an Irwin Quick-Grip.

I added cork pads and cut off as much spare plastic as I could, and I tried them out today with my home-made liquid goggles.
They worked pretty well. Only problem I had was the corks did not stick well after they got wet. If they made an even smaller one that would be ideal...Mine was the 1½" version.
What kind of adhesive should be used for sticking cork or rubber to plastic???
Also, what kind of adhesive should be used for internal work on liquid goggles. EVERY thing I have looked at says it is an eye irritant, and the aquarium sealant I found that is supposed to be safe for fish turns out to be silicone caulk that produces acetic acid (vinegar?) on exposure to water...
BTW, I managed to actually lose my lens while diving. It is somwhere between 25 and 40 feet down. I dove for hours looking for it with no luck. Guess I will have to order a few more lenses...
