Making an eccentric strap

[tel]

I couldn't agree more Marv - some mastery of the file is almost essential in this game. Quite often a part can be produced with files in the time it takes to even start thinking about setting up a machine.

You are right about button shapes as well - the scope for shapes is limited only by your imagination. One further word on buttons - a lot of folk advocate hardening them, they must have a far larger file budget that wot I have, in most cases the buttons are only required for a limited number of pieces and with care unhardened mild steel is fine.

Like you, Tel, I prefer them unhardened. Not only does it save the file, but the file marks on the buttons when you reach the right dimension are a very good visual cue to tell you to stop. (Those of us who become entranced while beavering away with a file need such clues.)
