Looks like a very good job.
I see you doing a few tools as well so.
I am not sure if it interests you but a linisher fitted with a Scotch Brite belt my be of some assistance to you, it cleans up metal a treat.
Its not really woodworking but could be related.
Here is a few shots of before and after and the setup.
The product.
Excellent for cleaning glue off clamps too
