Molding the Entex Porsche

[Mr Scott]

The bumper… At this point in the project I am running into several problems. I have a deadline of sorts, I am getting sick of the project, and I am running low on RTV. Curse that waste on the front fenders.


Big parts of the ends get chopped away for the Slave part, but I don’t want to do that to the master.




I used clay to “chop” off the extra parts of the bumper in order to conserve silicone.



Here is the finished mold.



The edges need to be plugged up. I use a combination of hot glue and packing tape to plug up the sides. The hot glue make a pretty good seal if I glob it on thick and then press the tape into the still hot glue. Then I smear another layer of glue over the bottom edge of the tape.



This is the mold that is going to wear out the quickest. I made a mistake in my “negative” thinking and have a thin flap of rtv that is not going to hold up well. The castings will require some attention to remove extra resin.
