For Colt style revolvers, I lube the arbor with bore butter. Hot dry days I need to relube after 4 or 5 stages. Cool damp days, I can go a lot longer. I used a pair of 1861 Navies in three matches over 15 days last fall without relubing the arbors. Only maintenance was wiping down the outside of the frame & cylinder each evening when I put the guns back in the pistol cases.
