Builder Tip-
Montana-Designs Turret Kits do not include the TOOL STOPS because typicaly our customers have the tools to make these locally. The only precision element is the pivot hole and that can be easily cut using a router with a pattern cutter.

Ref to the above graphic.
Blue represents a rough out hole on the Tool Stop that will allow you to insert the router cutter. Yellow is the pattern cutter, Purple is the roller bearing that will ride on the GREEN portion of the Tool Saddle. This will then open up the pivot hole to the same diameter as the Tool Saddle.
