Drysuit neck former

[Smiler1968]

The wife's drysuit needs new neck and wrist seals. The wrists are not a problem. The neck however............ I have seen pictures of home made neck formers. One to keep the hole stiff and the other to fit over the seal to help keep shape as it's stuck down. The first is a solid circle, the second is more of a flat doughnut shape. I have a firm local to me that is happy to make me some forms / templates out of Perspex. Question-, is there an ideal diameter of the solid one? Is there an ideal size for the doughnut one? I will go and measure the seal and the hole but I thought someone out there may have already made a set up.

Regards

Jerry.
