Looking for help on casting small parts

[e-paw]

I would go with a two part RTV ( Like they sell at Micro Mark ) to make your molds from. I have used it several times with very good results. As for your casting resin I can't say as I have no experience with that brand. Generally you want a thinner, as far as the viscosity goes, casting resin. A thinner resin will get into more of the fine details. You Tube has tons of videos on casting parts for pointers on technique.

Hope this helps.
