I have started with the seat and made the male mould.  This is awaiting final finishing and polishing before I make the female mould in 2 parts. I will use wet lay up as I do not have the vacuum equipment. The garage is too cold to do any resin work at the moment and it also needs a good vacuuming to remove all the filler material sanded off from the tank mould, still another 6 cycles of filling and rubbing down before this is ready for mould primer resin
