Ankle Locks

Since Im using a single caster on the middle foot i need to lock it from pivoting. I just took some 1/4" aluminum and cut out some wedges to lock it in place.

To make the template i held up a piece of card stock level with the top of the foot and took a pencil and rubbed along the edge of the ankle radius. This transferred the curve perfectly. Then cut and traced that onto the aluminum and cut with a band saw. Next i smoothed and adjusted with belt sander.

Then i just tapped a hole in the ankle and attached. Seems to work quite nicely. No play either way.

Ill do a little more trimming to make it pretty.
