First thing was setting up to make a plug of the fuse. The plug will be used to make a mold to make the composite fuse.
So I cut a left and right half out of mdf. These will be aligned and glued together.
Then I will soak the plug in think epoxy, and hit it with a heat gun. For those that do not know, this causes the MDF to soak up the epoxy. Then I re-coat it and heat it, a few times to get a good layer of epoxy soaked in. This gives a hard surface that can be sanded down real smooth. Most people will then paint it with a 2k car paint and sand and polish that. I will see how good I can get the finish with epoxy soaked mdf prior to determining if I need to paint it.
Here is the first half cut. I clamped down a melamine board (shelf from home depot), sprayed it and my mdf with spray glue, enough to hold it, not enough that it's permanently attached. lol.
Then I set up to cut down to that board. This allows me to cut one half at a time and then pull them up and glue them together. I guess I could have done something 2 sided and flipped it, but that seems like more trouble than anything.
The other photo is the two halves together along with a fuse for a 40" w/s version I just cut and soaked in epoxy, and one we cut several years back. I have made some changes to how the horizontal stab will connect, so had to change them up.
