What Kind of Foam to Carve
I am planning to carve an XB-70 from foam. Years ago all we had to use was foam from the lumber yard. Now I see several kinds(EPP,EPS etc)of foam for modeling. What type is the best for shaping? I can't find any modeling foam in blocks but I did find some foam in thick sheets. I suppose I could glue several sheets together and go from there. Any recommendations as to foam type and supplier? Thanks.

RE: What Kind of Foam to Carve
A little late but. The old insulation foam still works well but if you want bigger stuff you might try a marina where they use large styrofoam bocks for floating docks. I still have a block that is 2ft. by 4 ft. by 6 in. thick.

RE: What Kind of Foam to Carve
The denser foams are easier to work with but they are heavier. All depends on your needs. EPS is the lightest and can be cut and shaped with a variety of tools. It is soft though and needs seinforcement. Many people use depron for the structure and fill in with EPS. You should test out a few of the locally available foams. RCFOAM has a density chart on their website.
