Dremel with appropriate attachment?
Yep, got a Dremel but it's a bit vicious on little bits.
After a bit of experimenting this is what I've come up with if anybody has a similar problem.
I cut a 300mm piece of 5mm steel down to 25mm wide. One end is clamped in the vice and the rest of the bar sticks out on the side of the vice you want to work on - depends if you're right or left handed. On the bar I put a bit of 25mm emery tape held on with a tiny ratchet clamp on each end.
The little bits I want to shape and sand are very thin and only 10-20mm long, but the bits are cut 20 - 30mm longer to provide something to hold on to. When finished, the handle part of the job is cut off and the piece will need just a couple of whisks over the sandpaper to tidy up the cut off. Holding the bit between thumb and forefinger, the front part of the forefinger runs along the edge of a steel bar which gives good control but just make sure it is properly de-burred.
Young at heart.
