Centering block for Dremel 220 Drill press

This block is intended to hold a drill chuck for the purpose of centering round stock under the dremel for drilling or machining. Fully adjustable, this block is attached using four 1/4-20 screw with wing nuts.

The drill chuck came off an old 7.2V Ryobi cordless drill. The design can be easily modified to fit your donor chuck.
