Reamer Grindingattachment for D-Bitgrinder

This is a Reamersharpeningattachment for a D-Bitgrinder.
The Problem was that i couldn´t change the teeth because the settingfinger couldn´t exit the space between two teeth.
You won´t be able to grind reamers in the Dividinghead because the teeth aren´t divided as you would expect. Therefore you use the settingfinger.
My Spacer allows you to grind each tooth on a defined setting, but you can swing it away for changing the tooth by allowing the settingfinger to pass by.
