aluminum if i remmeber right would heat up alittle quicker but also disapates heat more quickly.. (i could be wrong its been awhile since i was in machine shop ) i was about to make a hammer-style shift **** for my car right before the end of the year but then the instructor gave us one last project that took the last 2 weeks

 

I just happen to be very lucky that I have access to these tools, my camaro would have taken 3 times longer to do if I didnt have these tools. Now Im trying to figure out if there is any way to do a parking brake handle.
