Tool Bit Grinding Fixture

Built a tool bit grinding fixture for the surface grinder. Can hold 3/8", 1/4", and 3/16" toolbits, aswell as 1/4" round using the shoulder from the 3/16" cutout. Still need to make a clamp, but nuts and washers work for now.

Has a 7 degree relief angle built into it, but if I need more I can use the wheel radius to help me, and feed using the (In mill terms) Y axis.

Feinwerkbau 700 Trigger Shoe

Made a new trigger shoe for my Feinwerkbau 700. It's made from 6061, has a serrated flat face, and fits on the OEM trigger post. Threaded M5-,8 and fits right on. Much nicer feel than the original plastic curved one!
