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.

See the pictures for forther information!
Sorry, no D-Bitgrinder, no sharp reamers!

Lower axis 5°, upper axis 45° for machinereamers.
I have no experience with handremers, i thing this is not going to work fine!
