Homemade chin spoiler looking for some feed back please.
I have a little experience with epoxy casting. This is a mahogany pattern my dad made in his pattern shop. This pattern is for a aluminum sand casting. This is what patterns and models like like, you get the idea.
But,
This is a epoxy and fiberglass cloth casting taken from a model and was used to cut a cavity and core in steel on a duplicator milling machine for a plastic injection mold and castings of the parts in epoxy for checking size. This is for a prototype mold making fiberglass impregnated plastic safety shoe inserts that was made in the 80’s. The project never made past prototype faze as they had a hard time filling the mold with material and the abrasiveness of the fiberglass impregnated plastic washed out runners and the core in the mold rather quickly. I do not have the original models the impressions were taken from.
There are quite dirty as they have been on a shelf for 40 years.
