After some adjustments I got the weaving going this week. I immediately determined that it is physically impossible to throw by hand through a 60" shed on this loom. There's just not the leverage to impart the velocity needed to get the shuttle to the other side. So I learned how to use the fly shuttle and about adjusting the drop boxes which is critical. If the box is lower than the shuttlerace, the shuttle launches over the fabric and ends up on the floor at the other side of the loom. Quite exciting.
The dobby is working great. It's nice to not have to worry about treadling with a 100+ pick sequence. The weaving is not as fast as I'd hoped, but acceptable. I am so fortunate to have got connected with this loom when I did. There's no way I could have accomplished this on the Macomber; I would have been crying.
