honeycombing foam cores

[Rcmaster199 at aol.com]

The easiest way I have tried is using the "Hot Knife" device I purchased  
from CST Sales. It's a steel probe about 5" long that gets hot enough to melt  
the foam, and is used like an Xacto knife. It is easily powered by a  12V, 
700-1000 mah regular wall charger (old Duralite wall charger is  perfect for this 
application), and only one hand is needed. I added a  push button switch on the 
handle of mine (Radio Shack) to give me heat control. 
 
I make a cardboard template, fit it around the core, and then cut  away. It 
takes much more time to make the cardboard template than to cut the  foam. Give 
it a try. I think you will appreciate the ease and simplicity.

Hi Gents,
 
I am in the process of trying new things, and I  have the need to honeycomb a 
few wing and tail cores. What I am trying to find  is a source for a power 
supply/variac and set up with the probes so I can  accomplish this. I seem to 
remember someone having a home made one that worked  well, but of course it's 
been a while and I can't remember who or  what.
 
Can somebody help me out here? 
 
Thanks,
-Mike
