Need help removing elbow type arms from Instron machine
Hello. I am hoping you might be able to help me. I have an older Instron machine that I think came from the 70's or 80's (maybe even earlier). It has this elbow looking thing at the top holding a roller style grip. I am wondering if you could help me in telling me how I can remove the elbow thing as well as the roller grip? Everything I try doesn't seem to work.
