I then layed the jig over cut out and dremeled out where the wire was till i could get the jig to sit half way below the surface of the azek. I then turned the whole thing over and poured hot wax around the edges of the jig, this holds the jig and fills the gaps between the jig and the azek. I turned it right side up again and used a razor blade to trim the wax flat with the surface of the azek. i cleaned the jig of any wax. I used a 3/8" drill bit and drilled a few holes in the azek about 1/4" deep so the mold would have some pins to line up the two molds later.I built sides up around the azek like a box. I then mixed up some rtv silicone and gave the mold a good spray of wd40 so the rvt wouldn't stick to anything, then i poured the mold.
After the first pour cured i pull it out of box and remove the jig I clean the jig and place it back in the mold i just poured. Now i build sides around the mold then mix the rtv, spray the wd40 and pour. When that cures you should be able to sperate everything and you have your mold. All you have to do is cut out a spout in the mold with a razor blade so you have a place to pour the lead.
The mold is very soft so i use a piece of wood on both sides of the mold and then put it in a vise for pouring. After i poured a jig i make surethe mold has time to cool down before the next pour. Also i used american wire 500# ss coil wire for the through wire.
I hope that you guy's can under stand what i did with out any pic's, I will be glad to answer any questions.
