Glassing…yuck!

Glassing has to be one of my lease favorites in modeling. Epoxy is sticky, gooey, and generally nasty. Not as bad as polyester but right up there.

But it seals just about anything from wood to foam so you have a barrier and strength to really finalize your masters no matter what they are made of. And BTW. Unlike polyester, epoxy doesn’t eat foam of any kind. A huge plus.

So the neck, hull and pylons are all glassed. Now they sit over night and tomorrow I can get back to work.

The silicone molds came out well and I already have the resin parts to tool. I hope to finish the secondary hull by this weekend.

Moving on…

BTW I use a light dusting of 3M 77 spray adhesive on the wood to help position and conform the glass cloth before I apply the resin.

Waste molds…

Today was honey do day and other stuff but I did manage to make a waste mold off the secondary hull base for the array. In order to fine tune this piece I need a hard resin casting to tool. Then mount that to the balsa hull master after I glass it and lock it in.

Basic procedure. Dam up the two halves and pour GI 1000 silicone. It will sit over night and tomorrow I can pour alumilite and tool it up.

More tomorrow.
