RE: My first pattern plane build
Randy,
As a learning experience, I'd like to make a small glass cowl starting from a plastic one. The plastic one comes in two halves. Would it be preferable to join the plastic cowl halves, fill it (with expanding foam?), finish it as needed (plaster and then paint?), wax it and then produce the female mold or is it better to make a mold from a single half, produce two glass halves and then glue them together?
Also, in post 20 you show the first step in producing the female mold by pouring what I imagine is an epoxy based liquid over the male plug. What is in that black mix? Milled CF and West Systems? How should this compound be made? Much like epoxy and glass fibers?
Finally, is the same wax used on the female mold as on the male plug? Does the glass layup require a vacuum or do you just lay down the glass cloth and wet it out in each half?
I hope you don't mind the 20 questions but since you're in the midst of it, I thought you might be able to help a fellow modeler.
Many thanks in advance, David.
