Im a very very noobie restorer, just dabbling atm. But ive cleaned up a couple of blades from rusted crap to what i consider a 'ok' condition using pure hand sanding.
Quick it is not, but its oddly relaxing
Started using 80 Grit and working up to 2500 Grit - Wet sanding with Grape seed oil on a Magnetic Jig i made.
Its basically just a pine block inset with a couple of Neodymium Magnets, Covered with several layers of Duck tape.
The back has a raised bar that the spine rests against. Allows me to sand without the blade slipping.
On previous scales ive managed to drill out the pins and save the scales.. All save for a pair with Terminal cell rot.
I junked the scales and saved these
Something ive done then as apparently its in the contract - Bear in mind im a total wood working beginner here - beyond a few lessons 25 years ago ive done nothing since.
Im learning as i go along, and having a bit of fun into the bargain.
Blade / Scales aren't perfect, it uses micro fasteners for pins and needs more work but hey ho. Got to start somewhere.
Scales are Maple lined with Brass. It probably wont ever be shaved with , more a folly really.
(For the purists the original razor cost me £2, one scale was in 2 bits, the other had a crack down the centre so there was no saving them at all)
Honing the blades up after restoration is something i may learn to do in the future, but its a hell of a learning curve so ill likely end up just sending a few of the better blades that appear to be sound to be honed.
Till i feel im ready to start the long learning process anyway.
