Before rebuilding the mold, wash the parts in warm water with a little dish-washing detergent to remove the rubber mold release from all of the parts. After the parts dry, rinse them with rubbing alcohol to remove any lasting release.
Now we have to put the bottom half of the mold (with the frame still imbedded in it) into the frame and rebuild the mold. Be sure that the mold box is sealed very well.
Mix the silicone as before (we can use the same amounts as the top half is almost the same size as the bottom) and pour into the mold box.
I poured the silicone mix into the mold box by slowly pouring it from the center out. Do this SLOWLY so that the silicone gets into all of the crevices. Once the mixture reaches the top of the mold box, I gently tap each side of the bold to remove any air that may have gotten into the mix during the pour. Once that is done, I used the mold release on the large piece of styrene
and placed it on top of the box and placed weights on it.
I let my mold set for 24-36 hours. After 24 hours I checked it by gently lifting up on the styrene sheet. If the silicone tried to stick to the sheet, I left it alone for another 36 hours. The styrene sheet is used to ensure that the bottom of the mold is flat to eliminate the problem that occurred when I did it the first time.

The Jade Fog, formerly: Dave: I hear TK is boogieing up to Allentown already. I’ll be heading out soon. Flamingo tote IS riding shotgun! For practice I went to an antiques mall yesterday to hone my visual acuity to spot deals from 15 yards or more. Hello Allentown!
