I have been switching the large post for the laser light arm in my Lyle Jamieson system. When I use my steady rest I have to use a short post. I have stripped both screws, and today the nut turns inside the little plastic holder. If I'm going to replace it I want one made out of steel, heavy duty. I will be trying my luck with Google. But if this happened to me, I'm sure I'm not alone and someone has already found a supplier for a steel component. I'm attaching a picture of the piece. Thanks in advance. Stay safe my friends. Aloha
