Hi Geo, I had not thought of changing from the raw brass and just buffing when needed. However, your post has got me thinking. If I do anything I think it would be gold plated, unless you have any other suggestions?
Hi Vic, they were done by hand, and I am not entirely happy with them, but time restraints means I need to press on. The method I used was actually quite easy, and it was as follows;
Cut an over lengthed piece of main spring and bend reasonably flat
Soft solder at the ends to a thin piece of oversized brass. I used 0.5mm as it is what I had for the dial base
Drill the hole where it fits onto the hour wheel
Then use a dremmel type tool with grinding disc to shape your hand to how you want it. The brass helps to grip it, and also to control the grinding.
During the grinding the hand will naturally come away from the brass. Grind off to finally release the hand from brass sheet.,
Tidy up as required with dremmel type tool and then sand on a piece of wet and dry, both sides.
I put the hands on a 2mm piece of brass sheet and heated from underneath. As soon as hands start to turn light blue take the heat away
