Interesting. I like the idea of being able to dismantle a razor to give it a good clean out once in a while.
Peening kit for my first set of scales, recently:
* A spoon makes a great ball hammer
I guess the secret to this job is to hammer away with just the right amount of force: too little will take forever and too much could bend the pin. A spoon seemed to have the perfect weight.
* Axe head: a solid "anvil" to hammer against so the energy isn't dissipated.
* Flush-nose cutters were really handy to make a final adjustment to the pin length. After I'd fitted the pin & all the washers etc I could just nip a little bit off if there was too much to flatten down.
I used nickel-silver pins which were really easy to work with (ebay).
The big problem was drilling the (wooden) scales. I was sure I could manage by eye without a drill press... nope! It was kind of shocking just how bad a job I managed to do.
I got away with it though - I think because the pin hole in the blade was much larger than the pin (2-3mm v a 1.6mm pin). Even though the pin is lying at an angle, the blade can still rotate through 270 degrees and closes perfectly centered.
