After taking on the the small task of making a mould for a mate (Frog), i also thought i'd document the stages and make a how to for those that might like to tinker. i'll making two moulds, the seat base and the nose cone to suit a murdersickle such as this:

I'll go thru various details, things to look out for, materials and tools needed, precautions to ensure one's long life health, preparing the master or plug, the procedure of prepping the mould for first use, care and maintenance of the mould, prepping the mould and  laying up a part in the mould etc.

I am not an expert at this, nor do i claim to be, all my experience and knowledge is from a hands on approach working on my own projects and working with the 2 local hotrod fiberglasser's in town when they need a hand.

The seat base as picked up:

The coating is pressure pack can black, and will need to be removed, the seat will be sanded and all blemishes sanded/filled with putty and a 2 pac primer will be applied, sanded and re-applied.

The concave cutout at the front will be given a temporary filler piece and smoothed out square, this will enable the produced seat base to be modifed to suit the individual bike or owner's needs and tastes.   Once the mould has been pulled, the fill in piece will be taken back out and the seat base returned to it's original condition albeit ready for topcoats if desired.

The nose piece will be similar, but as it's a flimsy part, i'll show methods of bracing and jigging it up so that it keeps the correct shape for the moulding process.  sounds hard, but it's fairly straight forward and the way you go about it ( there is more than one way) will depend on if you want to keep the original piece ( master) or not.  If you don't wish to keep or it doesn't matter if the original is damaged/destroyed when the mould is pulled off than you can get a little rough...
