Balsa Fin Lamination Clamps

Recently I made extra fins for a second Quest Cobalt model.
The kit has almost 1/8" thick fins. I only had 1/16" balsa on hand.

Two pieces of 1/16" balsa were cut for each fin.
These were glued together with white glue.
To get a even clamping pressure and to prevent warping, craft sticks (Popsicle sticks) were set on either side of the leading and trailing edges.

Clothes pins were clamped over the craft sticks.
The craft sticks also prevent the clothes pin pressure from making dents in the balsa.
I sanded the new 1/8" thick laminate pieces down to a little over 3/32" thick.
