Molds are done, and nothing stuck together! So far, so good.

Pic of the foam core, I think 5/8" diameter, sitting on top of a plastic cup to keep it round. I've stuck it with .032 wires, which will suspend the core in the mold. (In theory!)

Molds, with locating pins added. you can probably guess the core assembly will get clamped in place when the molds are clamped together, suspending the core. That's the plan, anyway! What could go wrong?

Black tire mixed up, and time to inject like the wind... As the minutes tick by, the stuff gets thicker and thicker. Be prepared to make a mess. We inject thru a little port in the top, and there's a bigger port that will dump access when you've filled it to the top.

Came back the following day, because my shop smelled like holy heck. But I got a usable tire out of it, with some flaws, but they could be addressed. :-) Time to make more until I run out of material because the stuff has a very short shelf like once the containers are opened.

Canopy time. I had a partial sheet of Vivak from a previous project, I think 050 or 060 thk. I was hoping I could just do a manual pull (heavy pull!) on the plugs. turned out alright for a prototype. There are better ways of doing this!!!

Casting some aft fuselage inlets, then hogging them out on the backside, because they're a bit heavy... Also casting some flare rail launchers, eventually to be mounted on top of the fuselage.

How I computed the Wing AC, it appears it hovers just ahead of the wing pivot, depending on how the outboard wing is swept.
