Converting to Warp-Weighted Weaving

I always wanted to build a warp-weighted loom, but with a 48" Cranbrook ("Louise"), a 52" hand made, and a 40" handmade in a small house, I just don't have the space.  A woodworking friend traded me weaving lessons for what he calls "loom bears."  My friend used and finished maple to match Louise, and rounded the egdes and ends as well.  A solid polished aluminum rod from which a 250 pound man can do pull-ups and I am in business.  I put 1 pound of sand into a zip lock bag, and then put that into another zip lock bag - 100 times.  I put those bags into cloth bags I sewed from thrift store sheets, with a loop added. 

I am in business!
