Just want to share about some clamps I found that work great on the longarm. I don't like the clamps that came with my longarm so have been looking for anything that would work. I found something called a lilWeggie today at The Tool Store in OKC. I tried them out when I got home and they work great, no more hurting my hand, they work with just your thumb. Check them out
