Foam Factory Hot Wire Cutter

I'd like to try a build. I will be using Dollar Tree Foam. Has anyone used the Foam Factory Hot Wire Foam Cutters?

I've heard that a hot wire cutter won't work if you leave the paper skins on the Dollar Tree foam board . I just use a new razor blade .

Rats. Tried the Exacto knife. I did a lousy job (not too bad on straight lines).

Don't try to do curved cuts, a bunch of straight cuts taking off the high points works better. Sand the curve smooth if needed.

That is correct, if the paper is left on the DT foam the HW cutter will not work. I use the DT foam all the time as templates for wings and curved fuse sections.

I use the Olfa cutters with the slide out blades. Thinner and sharper than the Exacto. Break the end of the blades off when they get dull. The foam seems to dull any blades in a short time.

No Hotwire cutter will cut foam and paper at the same time. The only way to cut with a hot wire is bare foam. But you can easily peel the paper off, then glue a new coating paper back on. Just keep in mind that the paper may shrink a bit from the glue drying and curl the foam. Lots of threads here on how to cover foam.

I can use an exacto blade until it is worn away to nothing. The trick is that i have a sharpening stone on the table to touch up the edge often. Very often.

Never try to make the cut with just one swipe of the blade. First cut mostly top layer of paper, second mostly foam and third is the rest of it. Never try to cut with the blade straight up and down, always with blade angled to the foam. Even with the paper off, it is better to do multiple cuts.

if you ever get any MPF foam, you will love it as it cuts like butter compared to DTF.

Oh yes and as Balsa or Carbon said .........Practice

MPF ? I googled it. Is this what you are referring to?

Yes that's it. There is also a thread on rcgroups about it. It came out as a replacement when blue fan fold foam got hard to get. It's basically all I use. About 6 millimeter thick with no paper or plastic coating. Another reason I like it, is that the fellow that sells it, only lives a few miles away from me.

now that I am at my computer and not on my phone.....


Go to the site you had and click on "about us" and it gives you some different links and a little of the history.
The company is run by "Springer" here on RCG, who also does "One Sheet Kits"

MPF is what we have as a Depron alternative !

US made Right here in the Midwest aka Michigan

Deprons' maker and the EU have LET US DOWN !!!

So, as a consequence, I support MPF, totally !

Is there a substitute out there right now (in the USA) for depron in thicknesses other than 6mm? Particularly 3mm, or maybe even some thinner material.
I am aware of MPF, but as far as I know they only supply in 6mm.

The easy way to end up with foam of whatever thickness you desire is to make a hot wire cutter and slice it yourself.

You can get VERY thin slices if you like. The one I show here is 1 mm and was sliced from Dollar Tree stuff.

Showing my hot wire cutter. Its big enough to cut off 4 foot sections of foam and I added an adjustable tension bar for cutting up smaller pieces so I only need one hot wire cutter for any job.

I buy full sheets of eps, 2" stock gets me about a dozen or much more planes out of it depending upon the scale. I have tons of laminate "Formica", on hand for making jigs and patterns with. Its a little tricky getting used to cutting out the pieces with a hand held but once you are used to it, its a breeze.

I used stainless steel fishing leader on my other ones, this one uses stainless steel crafts wire. I tried guitar strings in the past, i barely got a few cuts out of them before they broke, i also heard of some people using piano wire.
