Hello, I have a new to me counterbalance loom, handmade, thirty years old.   It has 5 shafts, with the middle one being a counterbalance and no heddles.    I cannot for the life of me figure out how to tie up the treadles.   In the pic I posted, the middle two treadles attach only to the counterbalance.  I have the treadles tied up 1, 2, skip the middle two, and then 4, 3.  4 and 3 don't move consistently and when I press the 3, the 4 often stays down.  I also cannot press the 4 and the 2 together.   I am so lost.   Completely new weaver here.
