I started cutting the center out of a (non stock) rim to put in another rim. When you made your m-7-1-hummer rims, how'd you cut out the centers? The one I've got is the rivet design, that looks like the center will not slide out of the rim once the rivets are cut out. I will probably have to cut around the whole rim to get the center to come out. I am just looking for others ideas who have done this and yours was a decent post. Do you still have that stuff? If anyone else who has done this wants to chime in, by all means, help me out.
