A friend of mine works at a machine shop. They have a oven that goes up to 2000 degrees for heat treating metal. First I would test the metal to se how strong it is. They take this machine that puts a little dimple in the metal and it will tell you how strong it is in rockwell. Then I can have them heat it and retest it. Has anyone done this before? I was also talking to a guy who has his DR. in some kinda metal ****. He was telling me that the heat treatment will remove carbon from the metal making it stronger. They also cool it in oil. He also said if you want to heat up metal and not make it stronger to cool it off real slow and the carbon will not be able to excape.

Then I asked about shrinking and expanding of the metal. He said that if anything it might expand 1000th. Depending on the metal, but it might not. 1000th is not that much I really dont think it will make a difference. There is not woing to be any warping either since the whole piece is going to be heated and cool all together.

A set of harden gears is about 7-800. I am will to give this a try. Tell me what you guy think.

 

i dont know about hondas, but in the world of RWD v8's pro gears are softer then street gears. they take harder hits without shattering, so id imagine heat treating them would make them brittle.

This has always been my thinking as well.

 

So the aftermarket ones that they sell are softer! That makes sense. I just assumed they were harder.
