Shrinking an RTV silicone mold

[Fomen38]

Larry,
In watching you instructional videos I recall seeing one where you soak one of your molds in Mineral Spirits overnight and it enlarges by about 20 or 30%. Do you have a method for shrinking/downsizing a mold? Just curious. I have some baits I would like to miniaturize. Thanks again...

I asked the same question many moons ago. Maybe one day someone will stumble on a solution.

theres a youtube video i think mike from alum made. it involves making your original mold and incorporating the mineral spirits in the silicon mold material. this will result in a life size original impression, but as the mineral spirits evaporate out, the impression becomes smaller by some amount.

Yes, you are correct. Mike did a tutorial on it which can be located on the makelure utube page.
