Alec Tiranti (the named man sadly no longer with us)invented a mould system in which plates and rings enabled moulds to be made using cold cure rubber.

A base plate, then two rings. The lower ring filled with wax. Models pressed in. Top layer RTV (cold cure )rubber.
Let it set. Flip it over and remove the wax.
Then fill another layer of rubber to make two layers of rubber.

I tried it and found it horrible.
No need to help me as I gave up on it 40 years ago.

For the sake of a nice chat; any good/bad memories you have??

I used the cold cure rubber to make drop cast moulds back in the 70's and 80's.

They worked well enough for me at the time.

I made my own masters of course.

Hello Jim
Good memories or did you ruin the kitchen stove?
I made some masters out of aluminimum blocks back in the 70's

Terrible material (Ha)

Brilliant foolproof system, I use it.

I was a tidy worker so the kitchen stove survived well.

It's cheaper than a vulcanising press, plus it handles Fimo masters without destroying them. Tony Barton (AB Figures) uses the system for making production masters, and few people would argue with the quality of the results. 🙂

We have one for sale if anyone is interested.
I've never used one before, clumsy me and molted metal probably not a good idea.

Great machine for small batch production. Simple, accessible, inexpensive. And it allows you to mold figures printed on a 3D printer.

We have one for sale if anyone is interested.

Is it still available? I may be interested.
