With steel shafts start with what you call npb at 12 as you will find flo around this area quite easily.

Gee, I have to wonder about TT's QC process. Until the recent
reintroduction of the Chinese Apollo's, they were consistently the worst
shaft I measured for residual bend. Some worse than 40 thousandths of run-out.

Thanks for the input Al. That's interesting. I know you can do ultrasonic
welding, I'm not sure how they would weld tubing with it but I am sure it
can be done. Cold drawn shafts are also possible. Cold forming strain
hardens the metal and you get stronger material, but I would think that it
Alan,
Just sat in a TT seminar in Austin and they claim, as they have for years
now, that the weld is done without foreign material and is sort of
"vibrated" together. I am sure they used that term for us laymen and it is
somehow symbolic of the actual process. They say after the weld, it is

Hi guys,
I did feel compelled to snip. I believe that shafts are drawn hot and it
is probably the residual stresses due to the heating and cooling and the
large amounts of strain associated with the drawing process that leaves
residual stresses in the shaft and these are what produce the resid

The modulus of elasticity for the low carbon steel and higher carbon steel is basically the same. It is the yield stress that is significantly different and would have no affect on frequency differences. The

ALL, the easiest way to check out on just how much carbon is in the steel, grind some of it on your bench grinder. If the sparkles are a lot and stay near the grinding wheel it has a very high carbon, but if
