Neck Gasket Replacement

I saw some questions about replacing neck gaskets.  It is relatively easy -- not as easy as wrist gaskets -- if you already own clamps and have tools to make Kokatat's jig.  I made one myself and have uploaded the files here:

I am sure it will not be anywhere near as popular of a download as my Mr. Hankey Christmas Cookie Cutter.

I believe I used a small coffee can to hold the neck up during the gluing process, but I can't remember for sure because it has been a few years.

I am still trying to figure out a way to make a full size tile-able PDF file so hand tools could be used. But really, a person could just hand draw it and use a jigsaw/band saw/scroll saw.

Use an empty plastic 32 oz. yogurt container, which is tapered and just the right size.

A second tip: To clamp down the gasket, instead of buying a whole bunch of spring clamps, find a bowl in your kitchen which has a rim the same size as your Kokatat-style gasket tool, set it on the tool, and put a heavy weight on it. This provides very even pressure on the gasket.

A third tip: to keep the disk part of your Kokatat-style gasket tool centered on the neck hole of your dry suit, tie a piece of bungie cord or paracord around the fabric of your dry suit.

I cut my gasket tool out of 1/4" masonite.  I use a one-piece ring, not a two-piece ring like the one in Craig's pictures.  I don't know why a two-piece ring is desirable.

I am sure it will not be anywhere near as popular of a download as my Mr. Hankey Christmas Cookie Cutter.

Damn. I was wrong. I posted this on Thingiverse yesterday and 30 people have downloaded it already. Only 4 takers for Mr. Hankey in the last month.

Also, looking at that can I used in the picture, It was tapered and it was a big cottage cheese container.  I forgot I used the one in my garage that is full of fine sander dust I use to thicken epoxy. I was trying to think of why I had a coffee can because I don't put canned coffee it this fine specimen of a body.

As for two pieces, I did it for ease of lining up and clamping.  As Pete mentioned, a heavy object would work as well, but I have lots of clamps so that is what I used.
