Ok so i figured out a way to unbend slightly bent items i dont know if it will work on short items like spindles and main shafts but it should will def work on tail booms and Torque tubes.. so i had a TT shaft that was ever so slightly bent and i didn't wanna throw it in there like that.. so what i did was heated the oven to 400 deg stuck it in for 10 mins rotated it 45 deg let it sit 2 more mins 45 deg 2 more mins and then i turned off the oven and pulled it strait out by the end and let it dangle till it cooled DEAD STRAIT now ...

Lets hope that you didn't take the temper out of it.

You would have to heat it up to a heat point hotter that they temtered it with, to reverse the tempering. So no need to worry about that .

Most metals are tempered in a kiln not an oven. No oven I know can ever get as hot as a kiln would . Just a small lesson on tempering .

Did you poke it with a tooth-pick to make sure it was done?

Kiln's are used to fire ceramics, vacuum ovens are used in the heat treating business along with a drawing oven to normalize with. In VoodooX's case, heating aluminum tubing that comprises a TT probably just stress relieved it.

I am grilling out tomorrow, so I could just use the bent heli parts for the shish kabob skewers.

I just need to remember to rotate 45 degrees at a time instead of 180.

I don't know one way or the other, depends on the material and what else besides aluminum is part of the TT.

sounds like a nice idea but be careful

Voodoo,
I worked in an annealing department for 42 years and even after the annealing process was stpopped the rockwell readings would continue to drop another 1 to 2 points on the rockwell scale. I just hoped that you didn't soften the shaft too much. Even with only 400 degrees you are softening the shaft ever so slightly. Being that you had it in the oven for a short time you my have not softened it any, and then again you may have.

I would be more concerned with softening the glue joint and resins (if the part contains those) than anything else.

Now if you had an ALIGN you could afford a new part.

If you had an Align, the part would already be softer than you could possibly degrade this one too, so the point would be moot! Let's not confuse quality with cost again, shall we?

Align T/T cheaper I think not The Velocity T/T is a paltry £3 for two tubes. Though I would guess, the power used to heat VooDooX oven cost as much as a replacement tube.
