Have you ever wondered this? (Nichrome VS Steel)

Dear Modeler,

There’s a pretty common question when it comes to foam wing cutting — with two competing answers.

Some modelers swear it’s one way. Others swear it’s the other.

(Don’t you wonder sometimes if people like to disagree for the sake of disagreeing?!)

It’s about the wire you use to cut the foam.

Most older books on foam wing cutting insist you must use nichrome wire. Nichrome is a highly-resistive blend of nickel and chromium, commonly used as a bridge element in homemade rocket motor igniters. (It heats up fast as it resists the flow of electricity through it.)

Other books say you can use steel wire. It’s fairly resistive, and works just as well — with one caveat.

So who’s right?

Well, both are, but Bob prefers steel, and here’s why:

First, steel wire is cheaper than nichrome — much cheaper. One hallmark of Bob’s approach to modeling is with a fixed budget you can do more of it if you find thrifty ways to accomplish your goals. (If you’re thrifty too, then the more you learn about Bob’s foam cutting methods the more you’ll like them.)

Second, steel wire can do pretty much the same foam cutting job nichrome can… if you use it right.

So how do you use steel right? Simple…

Add a little more current. Since steel isn’t as resistive as nichrome, it takes more current to heat it up. So with a little more current, steel can do the same job as nichrome, and you’ll still keep a few more of your hard-earned bucks in your pocket.

Bob’s 2-hour video on how to cut foam wings is full of money-saving tips when cutting your own foam wings. In fact, even though you spend $29 up front to get the video, you’re going to come out ahead in the next flying season alone for the money you save by using Bob’s easy and affordable methods for cutting your own foam wings.
