Best way to cut soft foam...

What is the best way to cut soft foam. I know I can use a hobby knife for outlining it.....but how can I cut the depthness?? I dont want it to look all trashy so I don't really want to try to tear it out. Any ideas??? Thanks!!

Jason

P.S. I thought about cutting it to the depthness (is this really a word?) and then glueing it back onto a flat piece.....but I dont have anything that will cut it in half....

Remember when flying inverted that down is up and up is EXPENSIVE!

I bought a custom made foam lining for my helicoper bag and I watched them work on it. They used a electric knife to cut the soft foam. It's the same electric knife you use to cut turkey or a roast. Make sure it's really sharp before you try to cut the foam. It will cut the foam really smooth and straight. They also used a hot wire or something like that, but the electric knife was easier and faster to use.

Take Care,
Cheers, Patrick

A razor saw will do it, I use a hot wire, made from some electric heater element stretched on a bow and connected to a car battery

Once you get your initial outline cut, if you are extremely careful and use a new blade you can work your way through the foam without too much trouble. You need to be sure that as you fold the foam back, you don't wind up cutting on an angle, however that is a piece of cake. As I said, the secret is a brand new and extremely sharp #11 blade on your Exacto.

you can get those 'breakoff' blade type knives
and use that. About 3" long.

i think that a pistol grip type soldering iron with the stock tip removed and a piece of coat hanger or a piece of wire with the same OD as the tip element.


I have never tried it but I have seen it done first hand.

Hope that helps.

Weigh it down

Weigh the foam down with a heavy object on both sides of the cut. I use a couple of steel plates and the use a regular exacto to carefully cut it. The plate makes a nice straight edge.

that is one of the best methods
I like copper wire is just a little easier to shape than a coat hanger
if the wire is more than a few inches you may need a soldering gun
with more wattage

Put the foam in the freezer for a few hours, then use a sharp bread knife to cut it. If you outline your cut lines with masking tape, its pretty easy to get a straight line.

I set my big car battery charger to 6 volts and clamp a thin guitar string from pos. to neg. and it cuts VERY clean and smooth. I had to change strings occasionally as they do burn out at 6 volts. I think 4 v. would be perfect. I cut a 5"x12"x17" block to fit my box . 12"x17"x3.5" in the bottom and 1.5" in the lid

Nothing will cut it better than a band saw, slices up foam rubber like bread...try it, I've been doing it for years!

I've been making custom AV cases for years and the fastest, cleanest tool I've found for cutting foam is an electric turkey carver. You can achieve very intricate patterns with multi layers of depth by cutting the foam horizontally severl times and then reassemble and glue when done cutting the layers.

Next case I make, I'll post some pics.
