    Angle grinder straight edge cutting guide

    Today's project is an angle grinder straight edge guide that starts off as a modified store bought angle grinder guard. (Harbor Freight angle grinder safety guard 61680)

    I've had that guard for a few years and never used it because it tended to wander away from the straight edge during cutting. To solve that problem, I modified it as shown. I also improved the cutter depth adjustment so it's much easier to use for gradual depth cuts in thick material.

    Now you just clamp the 3/4 angle iron guide to the material and the "new and improved" guard rides along making a perfect cut every time. (thick material can be gradually cut in small increments safely) Say good-bye to that dreded wander!

    Black angle grinder shown is a Harbor Freight 4.3 amp angle grinder 69645.

    Straightforward, clear pictures and text, no endless youtoob to watch only to not see the critical step 'cause it's out of focus and zooms by in a second, I'd upvote this 1000 times. Very nice!
