Sponsons
The sponsons are assembled in a specific order
for a reason. It is not the fastest way, but it’s the
only way it can be done right.
Gather all of the parts for the right sponson.
The right sponson holds the turn fin, so it has
dowels in it,
Grab the right foam sponsons.
Test fit the 5/8 inch wood dowels in the 3 rear
holes. Also test fit the 2 aluminum plugs.
They should be a nice fit, without slop.
Prepare the sponson inside and outside plates by
lightly sanding the edges.
Put the RH sponson outside (3 big holes) on the
bench.
Mix up some 30 minute epoxy, and coat the
inside of the sponson plates and both sides of
the foam sponsons.
Laminate the foam sponsons and add the 1/8 ply
sponson plates.
Work quickly.
Put epoxy in the holes, and insert the 3 wood
dowels.
They should bottom out on the outer plate and
stick up above the inside plate.
Work quickly.
Use the aluminum sponson plugs to make sure
all pieces are properly aligned.
Use tape and small weights to hold the sponson
and check the length of the sponson with a
straightedge or ruler. It should be straight and
flat.
Allow to cure on waxed paper.
Remove and the aluminum plugs from the
sponsons and wipe off any epoxy.
