RE: [RCSE] Foam Cutting problems - Answer

[Scobie Puchtler or Sarah Felstiner]

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.

Lift,
Scobie in Seattle
