Finally got around to making my DIY Spindle Square for my small mill/drill although with my lame leg the doing wasn't easy like a half hour here and there.
Material used was a 4 & 1/2" of (oversized .0005") by 1/2" drill rod and a piece of 1"x1"x 6" of aluminum. Two 5/8" long by 1/4" 20NC cap screws and one 1/4" 10-24 grub screw. Cap screws with 3/8" heads are inset 1/4" into the aluminum. You will also notice the cap screw head are apposed to each other for good reason. Plus a couple of drops of weeping lock tight on the main shaft and two low cost dial indicators with your basic 3/8* standard stems and spindle.
Photo one shows my mill purposely moved out of tram with indicators not quite touching the vise. You can easily see by the horizontal aluminum bar the mill is way out of tram. Due to the fact I wasn't pleased with the pressure fit of 1/2" shaft I put some lock tight on it and a grub screw in the back.
Pimped it out some by rounding the ends with a 1/2" shaft 3/8" router bit and 1/8" ball mill then colored the ball mill grove with permanent red marker for contrast. Also made a temporary foam like case. Here's where I got the idea.
Rather than holding the tool in the drill chuck I held it with my MT3 - 1'2" collet and my mill is now in tram to .0005".
