Anyone who has laid out 100 ft or more of string line knows what a pain it is to wind it back up on those stupid plastic holders.
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
You will need a 7 inch piece of 2 x 4 preferably a hardwood (I used a piece of scrap dunnage).
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
in off top of screw bit adapter, this will be your insert for the screwdriver bit.
Measure the diameter of the piece you just cut off, this will be for the size of the first hole to drill. (Mine was ⅜ in)
Step 3: Drill hole
Center the hole on the side of the block of wood and drill a hole all the way through it's width. Don't put the insert in yet, set aside.
This hole will be for your handle.
Step 4: Drill out some waste
Now you're going to drill two 1 ½ inch holes
2 inches on center on each side of the block.
This is to help with waste removal later
Step 5: Making the retractable handle
Now we're going to make the retractable handle out of the quarter inch bolt by rounding off the head using the drill press and a file.
You want to file the head down until it's just under ⅜ of an inch so it will slide through the first hole that you drilled easily
