Fender Roller Again

Today I finished my friends gun case so I started the fender roller.  Its coming out really good but my welds are rusty so they aren't very pretty. In the half hour I worked on it i got the to arm pieces cut and ground down. Also I welded a 1/2 inch nut over a 9/16th hole in the outer arm and am using a 1/2 in bolt to lock the inner arm down, it works good.
