Yes, its a solid form made of 7 layers of 3/4" particle board. Glue is applied to both side lams:
Wax paper is placed over the form and then the two glued sides are placed over the wax paper:
Blue foam construction grade sill plate insulation is placed over the side lams. The foam helps to apply even clamp force.
1-3/8" holes are bored in the clamping form to accept C-clamps:
The outer clamp caul goes over the entire sandwich. The clamp caul is two [laminated] .090" scrap wood pieces 33" x 5". Then I glue 1" x 1" x 5" wood bars over the outside of the clamp caul to which the C-clamps rest on.
Ready for the clamps:
Apply clamps and let the adhesive cure 24 hours.
Clean up with DA:
Make sure the wax paper is >1/2" wider than the form so it will catch the glue squeeze out from between the side lams.
I leave the sides long so I can trim to final length after the lams are dry.
I also make the inner lam about a 1/4" wider than the outer side in case it slips during clamp up. Then I sand the inner lam flush, on the belt sander, with the outer lam after the glue has cured.
