You shouldn't need anything but some bolts. I guess it would depend on the type of jig you have. My jig has two small mounting holes to secure it to the press. However, I didn't think it was secure enough after it came loose and I gouged my ball while cutting down plug. So I used JB Weld and went around the base and smoothed it out with my finger to bond the two together. It ain't gonna move now!!
