Yes, I miss Jim and his inventive ways. I have always thought we should be able to build a gelplane for gliders. Very fine adjustments to allow leaving a thin layer of gel coat but remove the bulk of the material before using the sanders.

it would be easier that way! the problem with a "plane" is that the gelcoat/paint thickness is not uniform for several reasons. if you try and take a set thickness off, in some places you'll go through and get into the structure.
