Not too long, maybe three hours tops. Biggest key is getting the correct Dremel bits, I started with grinding stones to cut the big forged checkering off and progressed to steel carbide cutters to remove smaller amounts, shape the curves, and smooth things out. I did run some of the polish wheels over the surface to further smooth it out, but I never went back with and 600 or 800 grit wet/dry paper to clean off the tool marks.
