I devised an inexpensive way to build my own line spooler. Start with a 4- by 12- by 1-inch piece of wood for the base. Then affix two upright pieces of wood measuring 4 by 7 by 1 inches, one to each end of the base. Make sure there is enough space between the two uprights for your bulk line spool and two springs. Drill a hole through the two uprights at the same height. Insert an 858-inch bolt through one upright and slide on a washer, then a small spring and then another washer. Next, slide on the spool, followed by another washer, spring and washer. Push the bolt through the second upright and screw on a wing nut. Now you have a spooling device that allows you to adjust tension by tightening or loosening the wing nut.
