Also: Use a 12mm Trantorque from SPI to link to the shaft.

One more thing, once you have this nice round shaft to connect to, I recommend that you use a 12mm Trantorque from Small Parts Inc. to lock a sprocket or gear to this shaft.

All you need is a 22.5mm hole in the sprocket or gear and you are in business.

Also, make sure you use a metals sprocket or gear. A plastic one will not provide the hoop strength needed to make the inner side of the Trantorque clamp onto the 12mm shaft with sufficient gusto.

Finally, I recommend that you support this new shaft with two bearings (one on each side of the Trantorque). If you do this, the job of supporting the beautifully sculpted but difficult to mount drill housings is a snap. The two bearings support the drill, all you have left to do is keep it from rotating. Not a brainless task but with thought can be done well with ease.

Good Luck to all.
