After careful examination, it appeared that the reed was rusted beyond recovery, plus it had no lease sticks, shuttles, or a raddle (you get to look up all these terms).
While I had to buy a new reed, all the other pieces are fairly basic rectangular/oblong pieces of wood, some with openings at each end, some with nails spaced every inch. After consultation with the resident woodworker, and researching what each piece should look like, he found some nice scraps in the garage (fir, oak, and black walnut), and cut everything out.
I sanded and finished (Deft spray on laquer. Quick drying, looks nice). Then holes were drilled for the nails on the raddle (nails in drawer in shop area), a bit more sanding and finishing, nail installation, and I had all the pieces for successful loom use.
In the time it took to get to this place, my SIL's friend told me I should take the scarf weaving class at Multnomah Arts Center. It appears that one does not need to be a Portland resident, so I signed up.
It was great fun! We learned how to make a warp, dress the loom, and then, finally after all that (it took almost 2 3-hour classes to get there), weave! The scarf is really a sampler, 9 inches wide, with different threadings for each 3 inches. We'd weave for three inches, and then change to a different treadle order, so we could see the different weave structures.
I had to go in a couple extra times to keep up - here I was thinking I was the slowest weaver ever, but it turned out my weft was thinner than everyone else's. So I had to weave longer to get the same length of cloth done.
(Bicycle tie-in - I'd ride over to the Multnomah Art Center. It is a fairly straightforward route, at least for me. The center is a couple of blocks from the start of the Solstice Ride. Multnomah Blvd is trivial to ride up when one doesn't have 200k ridden through the night, first.)
Now I am trying to figure out what to weave on the loom at home. Dishtowels seem a good exercise, although my maximum weaving width is 15.75". I think it will work.
