Ron,

There was an article on the Historical Diving (USA) website about reconditioning a Divair regulator, and I believe that they had to make their own diaphragm for it. Here's some info:

Ron,

If you don't want to pour silicone, I made a new diaphragm for my Trieste II with nylon-impregnated fabric. I simply put a metal diaphragm plate on the fabric, and glued it in place with Shoe Goo. I then put the the fabric over the regulator box, and roughly cut the fabric. I put silicon grease on both box edges and spread Shoe Goo on the edge of the bottom box, laid the fabric on it, put more Shoe Goo on the other side of the fabric, and placed the top box on the diaphragm. I left it in place for some time (48 hours, I believe), then pulled it apart. I then trimmed the fabric to the real diameter of the box, and let it sit out for a week (to outgas). Finally, I re-assembled the regulator with the new diaphragm, and clamped everything in place.

You'll probably have to modify this for the Divair, but it may give you a start. You will need a plate that will cover the levers too.

I don't recommend this for anyone who is not very, very familiar with their equipment and diving. This is a "last ditch" effort to make something work, and for me it was worth the risk. The diaphragm is at the heart of a regulator, and it must, absolutely must, work for safe diving. To modify any diving equipment is to take your life in your own hands, and must be done at yur own risk.
