Howdy gang,
I just wanted to update everyone interested. I had a chance to do a little on the Firefox. I started laying the sheet wax into the bottom half of the mold. Now, perhaps the method I'm employing makes a little more sense. there are a few gaps you will note and these get smoothed over using clean clay. Also, I didnt go all the way up to the edge. Again this gets finished with clean clay to ensure the proper edge. see the pics, as always, questions welcome. Once I get the clay into the gaps and smooth everything over, pour sprue and vents applied, a liberal amount of mold release will be applied, then final rtv rubber poured. this will complete the bottom half of this stage one mold, then this process is repeated on to the top half. Enjoy the pics.
Sincerely,
Will

Looks great... but I'm not sure what the wax sheet is for, does it represent resin in the final casting?
So in effect you'll be pouring more rubber into these two moulds, then removing the wax sheet; leaving room for the resin to go - and you have a hollow casting?
Am I anywhere close on that guess?

On the money! And the parts will be all clean and smooth and look like they were injection molded.
:thumbsup I'm definately going to try this wax thing next time out!-Sarge

as Sarge said, you got it "on da money" as to what the wax is for..it is to give me a constant wall thickness for the actual resin parts to be cast from these molds.

ok,
I clayed up the wax in the bottom mold last night. Now I just need to add vents and pour sprue and she's ready to pour last half..as for the sheet wax, you can get quite a few different thickness(in thousandths), adhesive backed or not. note adhesive backed is a little more pliable, I chose .100 thickness. I think that will be thin enough, but still have strength once resin is poured in the cavity created by the sheet wax.

I have seen this technique described in another article using a MUCH smaller part. Thanks for posting the pics! A most ambitious project to say the least at this size! Your attention to detail during the molding process has really paid off in the production of a quality molding! Hats off to you sir, and keep those pics coming!
