Removing scales/pins

Ok guys, here's the deal.

I'm gonna start work on a beautiful Bengall 6/8 that I have.

The pivot has a small layer of rust (shouldn't be much problem removing). To get at this part with a dremel (which I hope to obtain soon) I would need to remove the scales.

The scales are in incredible condition for the razors age, they're almost like new but are originals. So I would like to keep the original scales but perhaps just replace the pins on each side. I can't seem to find anything on how to remove pins, but only to install them. How is it done?

Would you all agree on replacing both sets of pins to make the scales look uniform in appearance.

The blade itself will need a slight polish and I will strive for a mirror finish. From what I'm reading, a progression from 220 - 2000 grit is what is needed for the foundations. The some chromium oxide on a felt wheel to finish?

Any thoughts on this projects gents?

Since you want to keep the old scales, use caution. Apply masking tape around the pin to protect from scratches. DON'T use a Dremel or any other power tool, or the heat build-up may melt or burn the scale material.

Start with a fine flat jeweler's file, and get a nice flat spot on the end of the pin that has a washer. Then, make a tiny dimple in the center of the pin using a sharp point of a #11 Exacto knife and turning. Clamp a SHARP 1/16 drill bit in a small pin vise, and proceed to drill a hole in the center of the pin. When you have drilled enough to get the bit point about a mm or so down, switch to a 5/64 bit. As you drill down, the washer should come off. (Might need to go to a 3/32 bit next, in some cases.) Use a small, sharp pair of dikes to snip the pin flush with the scales. If the pin doesn't fall out, lift the end of the scale a little, slide a flat knife blade between the end of the pin and the inside of the scale, and push down. You may then have to grip the other side of the pin with small pliers and rotate/pull to get it out. It often happens that the pin gets bent inside, so won't fall out easily.

Yes, usually replace both pins. Easier to find 1/16 brass rod and washers rather than German silver ones.

If the blade is already in pretty nice shape, I certainly wouldn't start with 220. Try 1000 first, and go down if needed. You might try the Dremel #512E 320 grit "puff buffs" first, as those are good at leaving no scratches.

Seriously.

I agree with avoiding power tools. I usually hand-file them off. Mask around the washer with tape--I usually use electrical tape. Make a hole in the tape just big enough for the top of the pin.

I then grab a flat mill file and hold it vertically, with one end resting on my knee. I'm sitting down for this. Then carefully file the razor up and down on the stationary file.

Keeping the file still and moving the razor gives me a lot more control. The danger is letting the scales roll up or down, in which case the tape should save your butt. :)

I sometimes repin restorations two or three times if necessary to get the blade centering properly, and this way I can remove a pin without messing up a nice CA finish. Should work just as well on your minty scales. :)

Sounds good guys (but also tricky) I'll give that file technique a shot Josh.

I bought a dremel today (with a view to sell again before I head to Uni in Sept). I now need to find a cheap source for some chromium oxide and sandpaper grits.

Our local stores are complete rubbish for such items.

Anyone got any good links?

You might try a jeweler's supply. I get my best stuff from Rio Grande but shipping to Eire will be a problem. Send me a PM with your shopping list and I'll see what I can do.
