Allyn cut two plywood disks of equal diameter. One was fastened to the base, the other had a square hole cut in it to match the tapered mast. A table was placed to one side and shimmed to the same height as the saw.
The blade was set to the height of the flat side of the base of the mast.
The piece was slowly rotated over the running blade and the square section was nibbled away to a round section. This was then sanded smooth.
This next procedure has been shown in a previous WebLetter. It illustrates how to use a shaped member to make a fiberglass receptacle. In this case the tube is installed through the forward seat and bonded in place. The mast is inserted into the tube.
The base of the mast is wrapped in a couple of layers of paper, then wrapped with polyethylene film (plastic bag material). The epoxy will not stick to the polyehtylene.
Sufficient glass cloth is cut to allow for three laps around the base. It is draped over the plastic wrapping, wetted with activated epoxy resin, wrapped another circumference, wetted with epoxy, etc. It is important to wear gloves as it will be necessary to pull the cloth tight and "wring" out excess resin.
