Arrow cresting

[Bowsander]

Ive been brain storming ideas on how to make
an arrow cresting jig.  I wanted to make a post
to see other people's homemade jigs.  Thnks.

Here's mine. A sewing machine motor with a foot pedal to control the speed. Works great for the 25 bucks I got into it.

another question horatio, how does that arrow nock on to the motor? Do you just nock it right on like it was a string?  That was another thing i was trying to consider on mine.
