Re: [RCSE] Foam Cutting problems - Answer

[Bill H]

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.

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.

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
