No need to fit anything for hand guiding as the tension arm is lathed down for the manual wire guiding.
So just jog it into place before putting the machine into manual mode and run your wire left and right.
As long as you make the round bobbin plate balanced right, it should be fine with the stepper motor. Uneven and it can cause vibration and cause the stepper to jam at higher speeds.

Honestly Sean, this is an amazing piece of work you've done here! The guys you had providing you input on design did you well. You've almost got me wishing I hadn't built one of my own.
Take Care,

In the immortal words of Dr. Johnny Fever, “When everyone is out to get you, paranoid is just good thinking.”
I have had a hand full of emails asking if it has a scatterwind routine in the software and tempted in the future to maybe add one.
Was thinking along the lines of a random number generator to just pick a different position on the bobbin for each turn.
But another thought was to maybe allow the user of the software, to set the height of the bobbin and then set the speed. Then control the feeder arm via the cursor keys of the computer keyboard and have the movements record into a script as they move back and forth.
They could then save that scatterwind script if the pickup turned out ok and play it back on the next bobbin also.
