Using what resin and catalyst in what type of mold and how are you getting it in there??

I'm using Alumilite clear with a 2 piece mold (1 half HS3 and the other half quickset RTV )
I've been measuring by volume instead of weight, because I don't have scale.  That could be the problem.
I guess I need to find a very accurate scale because I'm making very small molds like volcano button lens that only require a few drops of resin.

I've been heating the molds in a microwave and letting them cure overnight in a 45 PSI tank.

That's almost certainly the problem. If you measure 5% by volume it won't be the same as 5% by weight as the resin and the catalyst are different densities.

Electronic kitchen scales are quite good enough... and to get accurate mixing, you should never mix less than about 200Ml

Ermmm.... not a good idea!.... let your molds cure naturally over a period of about 4 weeks, before you use them. You'll get much better results.

Found an interesting vid on casting with a silicone mold - I'd never seen it done before.



Can't wait for some Tron repros!

I have seen video before.

That equipment is very very expensive, and not really practical for most hobby/small business needs.

It is very cool though.  Depending on the model, it will vaccum de-air the resin, pressure cast and heat cure all in the same device.

It's been long enough. Where are pics of a new home-made tron shell??

Patience!!! Please!!!   I'll be posting part 2 of the mold making tutorial in the next two weeks....

After that, I'll get the first pics of the first shell out of the molds up! Just be patient! Good things come to those who wait......  ;)
