If I may add,,,, Get a piece of 1x2 about 16 to 18 inches long. Glue about a 2 inch piece of the various grits on it. But sand it first so the sandpaper won't take on the "wave" of the grain of the 1x2. Write on the edge of the 1x2 what grit it is.
Lay the wood strip down and keep the bolsters flat on the board so I don't "cup" the brass like I would using a piece of sand paper in hand.
I do work the curves with sandpaper in hand as I tend to get flat spots when I tried working the curves on the board.
I started with 320 on the end, then 600, 800, and 1,000. And since I do it sitting here at the couple of desks, I just use brasso to polish it up after I get it like I want it, or just tired of messing with it.
Brasso on a rough cloth (old towel) will leave very fine scratches its self.
So for the final light no scratch polishing, cotton balls or some very soft cloth with a light touch and same direction strokes. Yeah, I am now talking about fine scratching that it almost takes a magnifier or loupe to see them with.
If you can still see fine scratches with the naked eye, you aren't there yet.
See,,,told ya not to go there
Sirusly tho.... restoring a beaten up 110/112 is a lot of fun. But then you have to ask yourself, is it really worth removing the "character" of an old user. Other than maybe just a polishing.
I have enough old beaters that I have done it just to see if I could. Thanks to Dr. D and Trax and some of the others motivational lessons. Results are amazing.
Take before and after pics!! You will abuse yourself mentally, afterwards, if you don't.
now returning the podium (tide soap box) back to Dr. D
ps: Stay back away from the raised scale pins. Sanding those flat is a dead giveaway that a knife has been worked.
