Or as my Grandson says: "Dudes".
I took the Monogram classic NASCAR driver to start. I prefer a "half tray" type interior, so I needed to modify him. I trimmed off the bottom and removed the arms.
I then sanded the arms flush so I could adjust them where I wanted. I super-glued them and filed as best I could to conform them.
Finally I added some Squadron green putty to fill the seams.
As a final coat, I sprayed primer and sanded with 1000 grit where I could. Then a good coat of clear gloss to seal.
To make sure we had a flush base, I used a old paint brush and brushed some resin on our setup board. Then pressed the driver into it. This created an almost perfect base.
When dry we trimmed away the excess and we were ready to make a mold box and pour our silicone.
Our goal was to try and create a mold that did not need a second part, or needed air pressure. Not everyone has a tank and thought we could make it work.
We poured the resin and used a toothpick to "poke" the resin up into the hands and to remove the air bubbles inside the head. We then tilted the mold slightly towards the hands as the resin has to go over the elbows and back into the hands.
Here is my master caster grandson inspecting his work. Yes, looks dry :)
And it came out ok. Now we can more for our future builds.
