[TR] Grinding aluminum

[Ian]

NEVER grind it with a high speed stone such as on a bench mounted grinding
wheel.  When it "loads it up" there is a possibility that the stone will
come apart with catastrophic consequences for you.  I was taught this the
first day of machine shop training when I was an apprentice aircraft
maintenance engineer back in the olde country. I seem to recall that it was
due to differential heating.  If you have done it, then get the wheel
"dressed" (or whatever you call it over here), or even better, just replace
the wheel.

Subject: [TR] Grinding aluminum

Quick update on my DCOE project, I purchase a new set of intake  
manifolds, Cannon instead of TWM, and the fit is much better.  I'll  
be able to use my existing header without any modifications.

But now I want to do a bit of port matching between the intakes and  
the carbs.  What is the proper way to grind aluminum?  It always  
seems to load up the stone/paper/whatever.

Thanks,
Darrell
