Shaping HD foam for pedals

Recommended Posts

I'm going to refit my pedal board with High Density foam, rather than what it came with.

But i want my  3 pedals to sit IN the foam and not ON  the foam, so i need to shape it. I've looked at hot knives but they seem to be more for cutting easy shapes

for cushions or whatnot, but i need some kind of hot knife that can cut the foam down to half its depth and scoop out the shape of the pedal. I will not be cutting

all the way through the foam, so i;m struggling to know what kind of tool this is called or if they exist.

Anyone know what i'm talking about ?

Great idea - cheers

Unfortunately,   the foam has been ordered already, and i dont have that luxury now.  Should have waited i suppose and now i;m doing it the hard way.

 

So a hot knife - do any of them have a kind of wire loop on them so that can cut down to a certain depth and then scoop along to cut the bottom ?

Hot knives , wow , that takes me back a bit 😉

A multitool might work , it's effectively a tool which will cut by vibrating a blade , though if you haven't got one or access to one with the relevant blades , it would be cheaper to buy new foam !

Cut through completely, then, then cut the cut-out pieces in half in thickness. A hot wire can do that pretty easily. There may be modellers near you that do foam 'planes..? They may well have hot wire equipment (although it's easily cobbled up, too; search t'web  for 'diy hot wire foam')... ;)

That sounds like a great compromise,  ( and based on the what onehandloose said ) now that i've done it all back to front.

yes, cut through the whole foam in the shape i want, then slice the bit i've cut out in half, longways. I can then ' plug ' the hole with half of the shape i just cut.

Nice work daddy o.

It means i dont need a specialist cutter, just a plain old sharp knife
