Don't know if this is the right section but years ago I purchased a blue point straight and 90 degree 1/8 die grinder for port work. I've only done stuff for myself so it didn't get used a ton. A draw back to both of these tools is griping them good enough so they don't chatter without spinning the speed control way up. What i would like to do is actually take a piece of tubing and clamp it to the body of the grinders as a handle covering up the speed control and just use a foot pedal to control it. All I can seem to find are on off pedals like you would use in a blast cabinet. Anyone ever go down a route like this and find something.
