Step 26: Reload a Wirefeed Spool
So clamped a pipe in the vice and slid the big spool over it.
I bolted the small spool onto a chunk of threaded rod with two nuts and two washers.
Then I hooked the end of the wire through the hole on the inside of the little spool just like the wire it came with had been.
I spun the little spool with the drill, guiding the wire on and maintaining tension with my other hand.
Try to make the layers of wire as level as possible. The wire has some memory so it will try to jump off if you let go. When it was full enough I cut the wire. I hooked the end through the hole in the spool that's there for that purpose, so the wire is held on under tension and won't start jumping off or getting loose.
