crown guard lost pin fix

[Netbis71]

I had to find a solution for missing cg pin, and I am very happy with final result.

I tried to sand down original pin to make it flush and was a bit careless handling it. Pin ended catapulting from my tweezers across the room and I was never able to find it even after few days moving furniture in the room, so I had to come up with a solution.

Thanks to DIY section here, I used paper clip which didn't quiet fit so I had to grind down the diameter and sand it until it fitted nicely took me about 2 hours.

After mounting the pin I used 320 then 400 grid sand paper and refinished top and bottom of cg to make pin nice and flush with the surface, and give crown guard fresh brushed look, it was easy enough but I was a bit frightened. I think result looks great. I can still pop it out and touch it with polishing paste to make it shine, but I kind of like the way it looks now. This is for 47mm 1950 Luminor 372.

Tell me what you think, and if I should polish it to be more accurate.







THIS WAS ORIGINAL PIN. I think it looks better now. unk:

Looks great!

Agreed -- well done. A simple, albeit time-consuming, cheap fix. Bravo!

Final touches, pin sunken and polished with 800 grit paper, CG brushed with 3M extra fine steel wool.

It looks really good! Great job there. Would never have known it started life as a paper clip if you didn't say so.

Great looking mod/fix!
If you want to go for more accuracy imho you should polish the top more, I use grits up to 5000, then a final polish with a felt wheel and dialux green paste. Also, you should try to carefully soften/chamfer the sides of the pin. Something very very light.
Maybe you can see better here:

Notice how the edge of the CG pin is ever so slightly lower than the flat top.

Thanks kilo. I am in the process of making another pin. Nice round shape and more accurate with chamfered top edge. This one came out good, but under magnification it shows that it is not perfectly round, so it needs to be replaced, and I have fun doing it, so it's all good.

On your pictures is it a gen 372 or modded rep ? Looks beautiful!

I polished top of my pin for now.

nice work but the hardest part of modding pins is the chamfer on the pin which gives it the 'recessed look'. easy if you have the right tools and troublesome if you do it manually
