Varial Foam: Machining

Varial foam cuts like any normal PU or EPS blank, but we still recommend cutting with the highest bit speed.

Although no melting will occur, Isopropyl alcohol gas will be released when cutting so cut in a well-ventilated area. Varial Foam is non-hazardous but we still recommend wearing a mask.

Due to the high strength of Varial Foam, some internal tension exists in the material. After the first side is cut, the blank may spring towards the side which material was removed from. For highest -precision results, measure the rocker and secure the blank into the correct rocker positions for cutting the second side. After the second side is cut the blank will relax back into the natural rocker.
