My first experience using a tension box was when Bob and I wound my first warp onto the restored Weaver's Delight loom. I didn't own one, since none of my other looms have sectional beams, so I borrowed a homemade one from a friend.
Now, I have a whole box of rug warp, with lots of colors, and am ready to wind on my second warp. I gave the tension box back to my friend after putting the first warp onto the loom, so I showed Bob what I needed.
He drew up some plans, and when I came home from work this afternoon, he had most of it completed.
I found a wire coat hanger and made the two wire gates to keep the yarn from popping out of the tops of the open reeds.
Bob finished it after school. He picked up some 1" dowel at Ace, and some wing-nuts, cut the four tension dowels and added the posts for the wing-nuts to tighten them.
