Thanks Amarin,
I didn’t think of the YouTube university’s self help information.
There are quite a few ideas on dealing with exactly I imagine could go on with the journals of the camshaft.
I was amazed how the one you sited using what I call a straightening fixture and heating the whole thing.
In my trade we call that normalizing or some called it annealing.
The length of time used in an oven is normalization with an induced force to make an intentional direction happen.
Also this guy was setup to do it in business.
I wonder if he does aluminum rims straighten. I’ve seen that on YouTube.
A rapid cool in done with non ferrous but that was not included with their process and I can understand why due to the mass involved.
Just exactly how would you introduce a quench on a “casted part” has to be considered.
Guess it depends on ferrous or non ferrous materials with temperatures and the time soaking.
That presentation you found seems more logical that the next person who uses an acetylene torch in the center. He made a statement, “ to heat the spots surface until it almost melts!” Really?
No heat stick crayon or thermometer, seemed a bit scary to me for a one and only head that one might have.
Some crazy stuff on YouTube. Gotta be careful.
Aluminum takes up heat and lets heat go differently with each recipe used.
High silicone content in aluminum was quite the rage some time ago. 1970’s ?
But then, so was running the pistons and rings right inside the bores of the engine. No liners.
We know how the Chevy Vega’s German blocks killed that car life.
GM made a 9 million dollar total investment. Championed as the cheapest production car ever made from the start on the design boards until Roll off. Of course our military didn’t fund it or get one! (:)
A brother-in-law had one that he let ruin his credit to get rid of it.
This Years before the Lemon Laws got on the books in California and elsewhere in our country.
Thanks for giving me your time and I hope we can both can keep ours heads straight! (:-)
