Shop press accessories that fit the standard diameter common shop press. For example a hardened steel rivet set the reduces the diameter of the press piston to that of a narrow rivet set.
The same may be accomplished by using a plumbing pipe and cap and drilling a center hole in the cap and threading it so that it accepts a narrow rivet set that has a concave ending. Also needed are rivet set bases. The top rivet set adapter could be made with a thumbscrew to tighten it to the piston.
The narrow extension should be about 2" long, and about 5/16" to 3/8" in diameter.
And really for the adapter and the bottom plate the cost shouldn't be much more than $15 United States dollars.
