The part that bothers me is it has to be hollow so it can fit over a spring. I was thinking placing it to mold with the point facing down and doing a 2 part mold so the top part of the mold will fill in the center hollow. Reverse the mold and fill thru a small hole at the tip.

Your sort of right on a two part mold, but it actually would end up as a 3 part mold. You have to be able to take the finished piece out of the mold when it's done. With the fins on that piece you will have to be able to take the mold apart to get the finished piece out. The window end caps I make are a 3 piece mold. The problem with a small hole at the tip pour is air entrapment which will leave a void in what your making. I just made a mold for a power steering insulator for a 51 Imperial and it took 4 trys to get it right and I think I sort of know what I'm doing. |
