62-Racer Transom Help

[65Bowrider]

Ok, I’m a rookie here and about to tackle a big job!
No where on CSC do I see pictures of how someone handles a wetted piece of 1708 that’s 8’ x 4’, without wearing half of it!!! There must be a trick to this, and would appreciate your sharing.

Our 21 is sitting on a 1”x6” on the floor, blocked, leveled, straightened and ready to begin. The transom skin has been grounded & 3’ off transom on hull & bottom. We’re using Coosa board, ¾ oz mat, 1708 & epoxy for the transom.

Just a reminder, our 21 has no transom core, no stringers, no floor, only a minimal cap that has fortunately kept her from spreading.

Here are some pictures, and would like to hear tips on how to put it all together. Thanks.
