Cutting Foams

[Aqua sobriquet]

Someone on here, I can’t remember which thread it was, rather cleverly suggested freezing foams before attempting to cut them.
In my case I wanted to cut two 20mm thick foams from a spare 50mm thick Biomaster foam. Freezing and then cutting on my Bandsaw worked perfectly! Thanks for the tip.

Thanks for the tip.

You are welcome. Good work with the band saw, a very neat job.

For those without access to a bandsaw you can get similar results (but not quite as neat) with a large and very sharp non-serrated knife. Dampen the sponge before freezing. I tried serrated knives and hand saws but they did not work for me as the teeth snagged in the sponge.
