Put two inset T rails on my reloading bench. Sturdy as heck for my press and the same with a vise I can easily add or remove. Also gives the ability to move the press to where I want, even angled. I used JB Weld on the t rails (with wood screws) for added strength. It's solid as a rock.
Pic one, is a close view of the t rail side. Second is the full shot of the rails. Third is the mount of the press sitting on the rails and fourth is the press.
