I did a bit of work over the weekend.
I put a coat of epoxy over my intake mold to protect it from the poly resin I'll be putting on with the layer of fiberglass.
The foam mold started as a block of foam that I rough cut to shape with a hot wire foam cutter. The foam cutter is a homemade unit I made from a transformer, dimmer switch, and a guitar string. This was a much more controllable method for cutting than the first draft I carved out with a steak knife.
Final shaping to make it the proper diameter was done with foam sanding block.
In my first try a few weeks back I tried to add too much material at once so it got out of shape. I also learned that the polyester dissolves the polystyrene. (like dissolves like)
Less than stellar first attempt but a good learning experience....
At least it's hollow...
With nice weather Sunday I also finished the prep for the casting of the rear fender mold....
and laid down the first layer of glass...fingers crossed hat it releases as well as my test pieces...
Overall it seems that the fiber mat that I purchased to start with is a pain in the ass to work with. I've got some glass fabric on order in hopes that it's easier to manage.
Here's some more nice paint inspiration...
