Circle Cutter - Imperial Version

To better serve the needs of non metric users I converted some parts to the imperial system.

This thing only provides the conversion kit. For basic parts and Instructions see [Precision Circle Cutter](https://www.thingiverse.com/thing:3382980).

I changed the scales to 1/2" and adapted the length. This applies to the arm parts in the first place, but the width of the blade holder and the clamping bracket are also changed to 5/8". The scale on the backside of the clamping bracket is changed to an 1/16" pitch.

The screw holes are also tuned to no. 4 screws. The thumb knob is not changed, since I couldn't figure out the dimensions of #4 nuts. Evan Google had no idea. But if some one out there could help me, I will deliver this later. (For metric M3 nuts the wrench size is 5.5mm this might help you to scale on your own.)

Have fun!
