working with aluminum angle?
I have a piece of aluminum angle, 1/8 thick x 1 ½ x 1 ½ (about 24 in long). I need the angle to be exactly 90 degrees; it’s probably 92 or 93 degrees now. Is there any way to barely sand or alter one side at exactly 90 degrees, leaving me with an exact 90 degree piece? I have a small shop with basic woodworking tools.

- You might want to take it to a sheet metal shop & have them use their "brake" to tighten up the angle a little. This would be about a 1 minute job for them & they'll probably charge you about $5.00 (to go into their coffee fund) if anything.
- You are pretty much stuck with that angle. If you grind on that aluminum, it will distort and wont be stable. Kind of like releasing internal stresses in it due to the "skin" on the aluminum. I would take that back and see if you can get a perfect 90 from the place you got it. Take a Try Square along and check the whole supply. You take that to a shop and its $50 to reform and it will not stay there perfectly at 90 degrees. Have you though of a drill and tap a few 1//4-28 screws on the near edge of the angle leg spaced along the 24 dimension and to put a 3 or 4 jack screws in there so you could adjust to a perfect 90 against your mounting surface?
