RE: [RCSE] Foam Cutting problems - Answer
Thanks for posting this follow up, Jim. I agree that the single point method is a really good idea, especially for any extreme taper. I had totally forgotten that with your type of system, the pull points (clips) are ALSO the power points, meaning that a shorter span between clips means less resistance in the circuit. While not necessarily a problem, it makes me realize that my wire is always powered from the points where the wire mounts to the bow, and thereby produces the same resistance regardless of the insulated pull points, so I've never had to consider this issue. I imagine that the single pivot method allows you to go back to pretty much whatever 'power span' works best, saving you from the risk of having your pull points too close together for your given type of wire. Anyhow, thanks for the cool insights into some of the many subtleties of the hotwire world.

Re: [RCSE] Foam Cutting problems - Answer
I have cut MANY tip's of the same size. I believe your problem was that you had you wire clipped at 10". What current setting were you using? I cut with the wire clipped @ 28" with the current setting slightly below the 28" setting with no problems.

[RCSE] Foam Cutting problems - Answer
This is the solution to the small core wire breaking problem from my earlier post. Thanks to all who replied. Several people suggested a different wire. Several people suggested a different bow. Several suggested too much weight on top of the core. One person suggested to use the single point cut method (cut around a ivot) - The 1 was Roger from Tekoa I tried his method first (I already had everything I needed). It worked great. Easier to set up than the 2 point pull as well. Roger did say that the T-370 (his wire) may not provide enough resistance at the short wire lenght I was using (I had the power clips about 10" apart while using the 28" bow). Roger did not indicate if other wire (fishing leader being the most common suggestion) would work at that length. After using the pivot and single point I will never cut a large taper ratio any other way. It was way to easy, and eliminated all of the set up issues I have had in the past.
