Trya nd answer as many questions as I can. Eclipse pretty much nailed it though.
My plug sits about 1-1 1/2 mm below the top of the cart. The bridge was fitting it too snug with a 10 star tool. It worked great after I made it not as long.
As for how I get the hole all the way through. I stick the star tool in one side and hold the mold by the cast and gently push my tool through the other side. Same as paper clip. Then i twist it in circle to make it smooth on the inside. I kind of stretch the hole, so a bigger star tool might be better. Try eclipses 15 size.
To make it cure faster put it in hot hot hot water for about 5 minutes with it in the cast. Seems to cure it better. I'm sure everyone will find there own perfect way as it can be molded anyway you like.
