I think that a rolling fixture is useful only when making the blade from a blank. Othewise two strokes per side on an aluminum oxide do for me. I let the flat guide itself and slide in one direction only. . Of course the smaller the driver the less tactile feedback.I hqve one screwdriver holder with an embedded oxide strip and find it extremely handy.
Even though your package is opened I don't suppose you get a picture of the bits and pieces of the package for us?
Then a caution factory packages or basically the paper envelopes that typically watch parts come in except balance completes usually come in very special packages but any of the paper envelopes always require caution because it's standard operating practice for a lot watchmakers to put the old part back in the package. Often times they didn't label that it's the used parts sometimes they do.
Hopefully I'm on the right forum this time!
Thought while I was struggling getting my first project back together, I would try a pocket watch as I'd read they were a bit easier, so I bought this off Ebay.
I've fallen at the first hurdle as I can't work out how to get the back off! Don't think it screws off, as I've tried without success, so thought it must prise off, but again no luck. I don't want to apply too much force, just in case it actually does screw off. Anyone any experience/thoughts on this please.
