Files are one of the tools I use the most. Bastards 0 and 2, ring
files 2 and 4, half round 0 and 2 and 4 small barrettes 0 to 4, and a
set of different shapes. They were not cheap but last for years.
Then it is onto sandpaper on sanding sticks and on mandrels for the
flexi. Do not under estimate the use of a sanding stick.
There have been good answers to filing metal to true it up for
solder, but if the metal is under tension as in a ring band or bangle
it is a simple matter. Put the ring in my benchmate to clamp it.
I use a small bastard on rings, open the shank join put in file and
file. There is a video in the Orchid archives about a ring repair
If the shank is wide say 8 to 10 mils I use a number 2 saw and cut
through the join.
To the original poster, while filing looks easy it takes practise.
Filing 2 pieces of metal to true up for soldering when there is no
tension is extremely difficult to do well, so keep trying you will
How to tell if the solder join is good? Put a hair next to the
solder line they should be the same.
Only took me a few hundred solders to get this one down pat.
Also I do not put handles on my files as sometimes I pull the file
towards me and the handle would be in the road, my engineer father
taught me to file like this. If you let the file do the work holding
the tang is no drama.
All the best and file true.
