Thanks Gary. Almost got off on a tangent here designing a 8 foot long
battery powered hand held hack saw with that cuttin wirejust to cut the
occasional urethane sheet. The only time I use urethanes is for gas tank
work I use polystyrene for everything else. I'll lay this topic to rest for
foot.

Mark. I just bought a tail wheel just like yours from Aviation
Products Inc. but haven't been able to locate
a tail spring for it. Where did you get yours?

Building a KR2s
will work out, plus
others could borrow the machine. It would scale easily.

That's probably less time than we've killed dreaming up a "better" way to do

That is interesting Paul
Maybe next time around ask the fellow about the wire.
I could cut smaller blocks and glue it all together or
glue it all together - paste some .25" thick .25" under sized
airfoil templates on the ends - set the wash out - and let the
wire do the work following the templa
I buy my foam from a cool room manufacturer. They make their own
polyurethane foam sheet.
They pour a mix into a steel reinforced mould 1.2m x 2.4m x 1m deep and lock
a lid on before it expands.
This results in a block of predictable density foam that they then cut into
sheets (any thickness)

You've got me thinking here! Is that wire the same that Remington developed
for hacksaws some decades back? What is the diameter and where did you
locate it? I have several aluminum hot wire frames, 2'Long to 8'Long and the
