heated gears

[drs23]

02,

Didn't have them in anything, just lying on the porcelain burner, two hash marks from the off position.

Billy, thanks for the response. Didn't get a chance to pull them yet as I've been swamped but will try to get to them this PM. Would bead blasting them return them to their original color and pardon this question but where would one go to have the hardness tested?

Thanks,

Dale

Take em to a good machine shop and they should be able to test them. Since you had them directly on the burner, unfortunately there is a good chance they where overheated. I don't know the hardness of the Andrews gears normally, maybe someone else can answer that. But a good machine shop should be able to tell you if they are useable. Good luck and let us know how this all goes.

get one of them ir temp guns and put the burner back on simmer and see how hot it gets.

Dale, yes bead blasting will do it. As Tsani says a good machine shop will be able to hardness test them. Maybe call ahead to make sure they can do it.

Good luck.

if you have a local college and they offer any physics or shop classes alot of them have a rockwell tester and would probley be more than willing to test it for you. A good project for a student...
