Got a bit done in the last few days.
I made some paper templates for the sponson deck skins, transferred them to the ply & cut them out.
To make the paper shapes I lay a sheet of good old butchers paper over the area & run my fingers along the edges of the framework, creasing the paper.
Cut the paper about 1/8" bigger.
After trimming & sanding the inboard edge of the panel to match the main stringer, that runs from the tip of the sponson to the transom, they were given a coat of epoxy fiberglass resin on the underside.
The whole inside of the boat was also coated with the resin at this point.
Foam blocks were cut & fitted into all the spaces & sanded to shape.
Then on went the sponson deck skins.
I placed a bead of 1 hour epoxy on all the internal frame work, placed the skin in it's exact place & tacked it down at the transom & at the main bulkhead of the heels of the sponsons.
The left hand skin needed a cut on the underside of it to relieve the pressure where the framework sort of curves down & then levels out towards the chine, creating dip in the skin.
Then I stitch glued around the edges, keeping the skin pressed down & flat. Working forward from the transom. Some CA accelerator in the pump spray bottle is a great thing to have here, as everything is held in place by hand during this operation. The boat needs to be rotated upside down & sideways to get the CA to flow where you want it to go.
Then a bead of CA is run along the joins, a section at a time, allow the glue to wick into the joint then squeeze together & spray with accelerator.
Of course the other method of Epoxy on everything & an array of weights, tape & clamps also works.
Creasing the paper templates.
