De-pinned
Congratulations on a successful mission.
Its always less stressful when you dont want the scales. Hang onto them though, you might want them someday.

Well done!
+ 1 on keeping the scales, I never throw away anything that might come in handy one day.
A little tips when unpinning this way to help save the scales is to put a piece of electrical tape over the pin and scales, that way the tape will protect the scales when filing.
will keep the scales in my box of treasures hehe,
was going to put electrical tape on but thought I would test my luck and wasn't to bothered if I scratched them
+1 electric tape
Very handy tip, with and accidental slip of the file there is no worries.
Glad to see you didn't crack the bone. I agree with the others, that someday you may want them for something.
I noticed you have a drill press in the background. Have you tried that method before? For me, the drill press is easier than the "hand" work.
No I have not as I feel that I do not have as much control over a drill press as I do with a small hand file. I will give it a go but not on my ivory scales hahaQuote:

As above ~ it's all about slow & steady, especially with ivory.
Drill presses are great IF you have a centre bit to start the hole. Well done though I bashed a few to oblivion before I got the hang of unpinning.
I just tried the drill press method, worked out pretty good as you can see I filed the pin first to get it straight so it was easier to centre the drill bit

The blades are now being treated by the Electrolytic process
I use these to drill out the pins in my drill press - they are stiffer and less prone to 'wandering' than standard bits.

You still have to be careful though
