Perhaps you needed a better design...? If you want to use Aluminum, I would make a dog-bone style riser like Fly manufactures, and simply find a piece of 7/8" tubing for an adapter if you need one. Fly uses 6061-T6 and they hold up quite well. I realize you would not need to utilize any welding to create these, but they work.Empire087 said:Ok, do not make them out of aluminum if you make pivot risers, I just made some in welding and they lasted literately 5 minutes. I made something similiar to the universal powermadd pivot risers.
