This is my home made clamp to hold the riser and bottom lams in place while the belly lams are being buttered and taped down. This thing is worth its weight in gold!
I forgot to mention that the entire form is covered with clear plastic wrap before any lams are put on it. Here is a picture for the bottom lams and riser clamped in place. Even with the clamp, the riser will want to slide around a little. Might have to adjust the clamp a little till it all settles into place.
When the belly lams are buttered I use strapping tape to pull them tightly against the bottom lams.
Didn't look like enough epoxy? It's already starting to ooze out!
