Best Method For Cutting Memory Foam?

[sickfab]

Hey guys,

Thought I'd give it a shot to make my own foams out of memory foam since I scored a chunk for free.

Has anyone ever cut this stuff? Should I just bust out the exacto and go for it and try to be as neat as possible? Or, I have a hot wire foam cutter (for styrofoam) Think that would work???

Anyone who has done this, lemme know.

John.

Plasma cutter:twisted:

J/K I think an exact o knife would probably be just fine. If you use a straight edge and compressed the foam while your cutting you would get a nice clean edge."thumbsup"

I would say an electric knife... like the ones used to cut up the thanksgiving day turkey. If you have enough, test out a couple different ways before you hack everything up.

Straight edge would work too.

Are you trying to cut donuts or are you cutting a strip that you can roll up to make the donut? If your cutting a strip, just mash it down with a thick straight edge and cut with an X-Acto or box cutter (something razorbladish).

If your trying for the donut circle, try the same thing, but with something round the same size you need, and then do the same thing for the small one in the center.

I always use an electric carving knife to trim my foams, but have yet to try it on the visco foam.

YES an electric carving knife (think thanksgiving turkey) is the ONLY way to cut foam. Call your local foam shop... they'll tell you the same thing.

i hacked up my temper-pedic pillow with a bread knife. worked fine.

not the only way. bosch makes a specialty tool just for cutting foam. i'll see if i can find a link for it. pricey, but super cool!

You could also use a lightsaber"thumbsup" Personally I'd use a razor blade

Try to find a hotwire.

I have cut all my kreepys with a pair of scissors, perfect lines are not as critical with the memory foam from my experiences, the stuff compresses way diffrent than regular faom

 

[Mnster]

Sissors work the best I've found. Razors are good but since the foam sort of compresses it sort of screws up your cut.

100% correct

If your working with like a brick of the foam, make a template (circle, duh) compress is down on the foam as hard as you can evenly, and take an exacto and cut around the template. Then, make a smaller template for the inner circle. There you go, home-brewed foams.

 

[FrankyRizzo]

I use a hole saw and silicone spray.

 

[frdtrkguy]

I just made a set and used my band saw for the outside and a 2" hole saw on my drill press for the inner hole. They look factory"thumbsup"

just so everyone knows the foam kreepy foams are made of is different than the kind that is in pillows and beds. the stuff used in pillows and beds gets hard around 60 degrees because it is designed to use your body heat to make where you are laying softer. the stuff in beds and pillows gets harder the colder it is, and softer when warm. kreepy crawler uses a different memory foam and he has tested them down to 30 degrees without much change. sorry to burst all of your bubbles, but unless you can get the right stuff you cannot use your homade ones when it gets colder.

i'm glad you found that, otherwise when winter comes alot of people will be kicking themselves for using a pillow, unless they live in a warmer state.
