I built a v-spooler (by Fryby Additive) but wasn't thrilled with the hand crank. So, I downloaded Maker Dave's "V-Spooler Drill Attachment" and gave it a try. While it worked for slow spooling, I needed something sturdier to handle the torque of my 20v drill. I went through 3 bits in one spool.
I made some tweaks to increase tensile strength and handle higher torque:
I've already spooled 3x 1kg spools from a 3kg spool, and it works like a charm!
