Just finished my tool post grinder for my Sherline lathe. Made from a piece of 13/4 round 2 inches long and a piece of 3/4 by 5/8 bar. Bored out the round to 1 inch to accept the Foredom hand piece. Cut a shallow keyseat for the bar. Attached bar with two screws. Added two set screws to hold the hand piece in place. Milled out the bar to fit the tool post.
Photo shows the assembly.
Next task truing up my chucks.
