I removed all the casting and machine marks mostly with files before wet sanding #220 #320 and #600. I give them a quick polish as it helps me see if I removed all the casting marks. I then dull them a little with a medium scotch bright. Next after degreasing I used Jax black rinsed well and took it back with a scotch bright pad. I did the same on the steel parts.Nice job JohnBHM. Like the wood color and of the brass. Wondering, how did you get the finish on the brass to turn out the way it did? Darken with some solution and then lightly rub with steel wool? Would like the same look on future project.
