Odd parts of a used Macomber
I'm hoping the group can help me with two questions about a large Macomber loom that I purchased.
For starters, it has a strange, thin, single iron "arm" sticking out from the back of the loom and I can't figure out what it is. It's the only one, and doesn't appear to be attached to anything on one end, so I'm not sure of its purpose.
Second, there appears to be a second beam (equal to the front beam in size) with some "claws" on both ends that I'm also confused about. It slides onto the front beam, but I can't see the purpose. As is, the loom appears to be good to go, but I thought I would inquire about these two parts.
The loom came in peices, so I've put it together myself. Any help would be appreciated! Thanks in advance:)
