Chris, that's a really nice mold! What's it made of?

Hi . The mold is made of 8@90x45 building pine laminated into a block and then CNC to shape. Then I vac bag a 3 mm MDF sheet to give it a hard surface. Sprayed with white furniture lacquer to make it all look clean and to stop any spilt epoxy sticking to it.

This is the mold being 're-cambered' (I changed my camber profile) on the CNC you can see the 3mm MDF comming off at the top and the pine core being re cut.
Here's a sketch.

90x45mm is metric 4x2. 3mm is 1/8inch. I use the pine rather than MDF as it's much lighter (for loading into vac bag etc.) and cheaper.

@Chris: do you have any issues with warping? i wasn't sure about using regular wood for the molds because of possible warping, so i chose mdf instead.

Hi. No warping so far. I'm not heat curing at all so that helps.
