RE: Thecheatscalc's 36 tuning and assy
Fixing the tail shafts:
I had the need to try to fix a couple of bent tail shafts yesterday. One for a #36 and one for an #22a.
For main rotor shafts I usually use a Panavise, Vacu-Vise which has a "V" groove cutout in the head that can grip the shaft securely, by applying a LOT of force on the shaft I can usually straighten it out.
With the tail rotor shafts, this doesn't seem to work.
TINY variations in the shaft cause it to look perfectly round, but still rotate with vibration or a side to side movement... I had no luck straightening the tail shafts...
Looking for a solution to this, I tried heating the STEEL tail rotor shafts using a propane torch.
I heated the shaft until it was red hot, then inserted it into the vise, and clamped it down as tightly as possible to let it cool.
Once cool, I repeated this with the shaft rotated 90 degrees around it's own axis.
My gosh it worked!!!!
It was absolutely PERFECT after this.
Remember I tried this on the STEEL tail shaft holding the blades.
