I will measure and give dimensions as well if needed... as you can probably see, the pin chucking device has the basic 118 degree Tee shape for grinding the bit to that angle - more- let the bit expose a little more. Operation is done by rolling the wheel, dragging the bit on the stone and relieving the tip by rolling to the right as you pull it to you across the stone. Most simple to use and very good results can be seen quickly with the loupe. Keeping the lands equal is still the necessary portion, especially with very small bits.
