Square drive coupling and key for taper lock pulley
Hi All
After broaching the square in the adaptor to drive my slip rolls via the industrial clutched sewing machine motor setup. The keyway and key needed to be cut and made. Link to motor set up: https://www.homemadetools.net/forum/...angement-77400

This post covers the adaptor bush completion and the making of the key.
The taper lock pulley and bushed arrived so the first process was to cut the keyway. The adaptor bush was set up in the mill vice and to ensure the orientation of square to keyway position a parallel was used to align.

After milling the keyway this was then used as a gauge to make the key.
The key was made from a piece of 3/8" square steel cut just over length and ends filed to full radius.

The key is pushed into the keyway and this highlights the tight spots once removed.
