Hey guys,

 

I just had an idea. I make bamboo fly rods. In as much as the form would be
hexagon in shape, do you think it would work for what we're trying to do
here???

I could taper these puppies to whatever I wanted to and if only the power
fibers of the bamboo were used to make them, there would be hardly any flex
at all.

Same problem here; even tried drill rod on my south bend with the traveling
rest and tiny, tiny cuts, and the deflection was still unacceptable (not to
mention genuinely scary whipping about of the work piece. Aluminum and
brass were an utter waste of time.

 

Many years ago, I bought a tapered STEEL tail-boom form, bright yellow in
color with a threaded end and a hex fitting - clearly a ??? for some piece
of machinery. Mine is about 15" long, ~5/16" at the fat end, ~.070 at the
thin end, and straight as a string. Happy to post pics if there's a
scrounger out there who thinks he might recognize what the original purpose
of the ??? was. It APPEARS to be a piece that, due to fragility, was
designed to be replaced fairly frequently - perhaps cheaply?

Bill,

I've tried turning down some boom forms on my lathe and the trouble I'm
having is with the material flexing to the point that I just can't get them
done right now. If your friend is able to make them, I'd probably purchase
one. In the mean time, I'm going to check in with some of the guys in
another group I belong to, to see how I can overcome the present problems
I'm having with making these booms.

 

Thanks and please keep me posted as to your success with these puppies,

Ren

Hey Gang,

Other than the .25 x .110 x 18 form that Ray Harlan sells, is anyone using
other sized forms and if so, is there a commercial source or are are you
having them made? or, are you using the Ray's form for smaller and shorter
booms? I have a friend with a CNC lathe and we're have bartering some work
back and forth so I'm looking into havinmg him make me some custom booms if
practical.
