Per Brian Nystrom:
Yup. I've repaired several of them and it's not difficult once you make
the forms (two discs and a ring). If you intend to repair your own neck
seals going forward, make the forms out of something durable, like 3/8"
plywood, then cover the surfaces that will be exposed to glue with
packing tape. I have a Webshots album with pics and instructions at:

Thanks. That describes it very nicely.

One question: when you cut the large disc, did you observe the 10.5" size that
Kokatat calls for, or did you make it a little bigger to allow the small clamps
around the perimeter?
