    ACCURATE 1/32 P-47N WHEEL

    I found a couple in service photos with the tire pattern on the right...I don't know what the pattern would be called, but I did them just to be different.

    Vacuum Chamber or Pressure pot?

    Same here, I have never use mold release nor talc. Although I have sprayed some (just a dusting) into a mold that was an open face mold and I only needed one more part from it before I cut it up to recycle. I used a Q-tip to rub it around and let it dry before pouring. I got one more perfect casting out of it...

    Vacuum Chamber or Pressure pot?

    I use a vac chamber for the RTV, I mix up a batch, vac it, making sure the container will be big enough because it raises dramatically. Then pour it into the masters, letting it puddle from the bottom up, then back into the vac chamber for another suck. The chamber I have is an old vintage pressure cooker, it has 6 wingnut dogs, and is extremely well made, heavy and solid. A one inch thick Plexiglas lid with fittings for the vac gauge and hose was made for it. The pressure pot I use is the cheapo from Harbor Freight, I have gone through several over the last 20 years, the only issues with them is the consistency of quality. (check the wing nuts before buying one) Sometimes the seals have to be re-set and I have a mark on the tanks for the alignment when I place the lid on the tank. Once I pour the resin mixture into the molds, I tap the sides (and sometime squeeze the molds) to help release any bubbles. I have almost no issues with trapped bubbles... I also use Platinum cure RTV, I have an old cookie sheet my wife was tossing out that I use to fast cure the molds. I have a space heater that has no elements exposed, the sheet sits on top of it and is the perfect temperature to cure the rubber in about an hour, it also keeps my casting room the correct temp for the resin I know the "big guys" may do things differently, but this works for me.

    I also toss in the 'chute packs and proper joystick grips.

    Kitty Hawk OV-10 AM products

    Thanks. I looked at theirs online, and it look like they glued up the kit parts and added some seat belts. They may look better in person though.

    If they do the full pit, I hope they put a bit more effort into it compared to their seats. (OK, I am a direct competitor, so my comments should be taken with a grain of salt...LOL)

    Good catch...
  11. The butt snapper is behind and in the middle of the shoulder straps on your resin seat.
  12. I sent you a couple drop box folders via PM. Maybe you can find something to help there.

    F-16 ADF

    I started this conversion several years ago, but stopped when another company was doing them. I just found one of the early mock-ups in a box. I have refined the base bulge and the fin, along with the antenna, HOWEVER I have no clue where the masters or the molds are right now.
