I use a really simple set up for a shuttle race when needed. Just tie a lease stick around the beater using a strip of nylon fabric (you could use some old nylons). Tie it fairly tight. It's easy to raise or lower the shuttle race and it provides just enough support so your shuttle doesn't do a nose dive. It's also flexible so that when you beat, the race doesn't hit the woven fabric hard. And, it didn't cost me anything!
Nice solution Kathleen. I added a permanent shuttle race to my Woolhouse Tools Carolyn, but it isn't as pretty as the one on the Jane loom in the photo above. I wonder why table loom manufacturers don't think weavers LIKE shuttle races????
