A Dremel has been my "machine shop" for years. Very handy devices and one quickly gets over the expense of sanding disc and other bits when considering alternatives.
I've been dreading reaming the horizontal stabilizer bushings after reading comments of slowly twisting reamers with vice grips or grinding the end square and using a small wrench. That brought visions of spreading the task over two or three days in order to not go craze with the drudgery. Looking at the 7/16" reamer I decided to try and grind a hex shape that might fit the ratcheting box end of a 5/16" Gearwrench combination wrench. I introduced the reamer to Mr. Bench Grinder and soon had a rough hex that was good enough for the box end to get a secure grip. The pictures show how rough the hex shape can be. The small box end clears the aluminum tubing but blue tape protects against an awkward slip. Reaming all of the bearing tubes took a little over 10 minutes, including stopping to take a couple of pictures. It was such a pleasant surprise that I went ahead and installed the bearings using the drill press / sandpaper "lathe" and frequent test fits. It all went without a hitch.
