So I made one with a retractable handle that you can use a drill with any quarter inch screwdriver bit to wind the string up faster than hand winding.
I have put on over 300 feet of string on one of these with no problem.
Step 1: Materials List
One quarter inch bolt (3 - 3 ½ in long).
One 5/16 inch threaded insert
One 5/16 inch bolt with the head cut off and nut.
One quarter inch screw bit adapter
Step 2: Cut top off screw bit adapter
Measure the diameter of the piece you just cut off, this will be for the size of the first hole to drill. (Mine was â in)
Step 3: Drill hole
This hole will be for your handle.
Step 4: Drill out some waste
2 inches on center on each side of the block.
This is to help with waste removal later
Step 5: Making the retractable handle
You want to file the head down until it's just under â of an inch so it will slide through the first hole that you drilled easily
