Right sponson does all the work…
Be sure to make a right and left sponson…
Sponson sleeves in place.
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 sponson.
Test fit the ½ inch wood dowels in the 4
rear holes. Also test fit the 2 brass
tubes.
They should be a nice fit, without slop.
Prepare the sponson inside and outside
plates by lightly sanding the edges.
Mix up some 30 minute epoxy, and coat
the inside of the sponson plates.
Also put some epoxy on the brass boom
tube sleeves. Shove the tubes in until
they stick out the other side.
We don’t want any epoxy to get into the
boom tube sleeves.
Do the same for the 4 wood dowels.
Put the inside plate in place, being sure
that the tubes and dowels protrude on
the other side. They should all stick up
above the side plates.
Work quickly.
Put the other sponson plate in place,
aligning the brass sleeves and dowels.
Make sure that the sleeves and dowels
go through both sponson plates.
The tubes and dowels should protrude
through, and be flush with the outside
plate
Use tape and small weights to hold the
sponson and allow to cure on waxed
paper.
