Ok, so the #$$%^& table insert is not optional :-(
At least I got to cut a little steel before breaking my first blade.

I've been catching up with various projects but one that's been a bit difficult is mending a music box. I'm not sure why I'm bothering - probably because I think things ought to work even if you don't use them.
It hasn't worked for at least 55 years, and there is part missing from the governor so I thought I'd try and make the missing part. I had no illusions over how difficult this would be. I don't have a drawing or a part to copy. It is about 2.5mm diameter at the widest part and the pivots are 0.65mm in diameter. It requires absolute minimum friction as it is a worm gear driven by a gear wheel.
I've had several failed attempts - the first photo shows three of my attempts, the second photo shows what I was trying to make. I was hunting for a better picture when I came across photo 3 on a suppliers web site. Apparently I could buy the missing part for $2. I sent them an email. Well it tuns out that's $2 for the part plus a $3.50 small order fee plus a $3.00 document & processing fee for an international order plus $16 for the postage.
Back to plan A!

I picked up a lovely SIP P1-2 (swiss made) 200mm rotary table a few weeks ago and have spent the last two long weekends adding an indexing adapter (i'm pretty sure SIP didn't make an adapter for this model , contrary to what Tony @ lathes says)
I have had a pair of double-sided index plates and brass fingers hanging around for a while and though they looked about the right size for the job.
The only way to attach the plates is to make a slide fit into the SIP's dial cover. The bronze tag on the left -back of the adapter is adjustable from the front via a tapered grub screw so the adapter can be locked against the fiducial marker quadrant (and no, this has nothing to do with me assuming the Swiss would obviously make the quadrant 90 degrees and machine out the section without measuring, then spending half-a-day machine a fiddly-arse bronze piece to fix the problem .. oh no I always meant it that way - cough cough)
The handle was a ********* I could only find unknownium stainless bar in my stock and when I put it all together it just stuck an galled up *&**&***!!!!! so every thing had to come apart and have little fiddly-arse bronze bushes to keep the SS S*** apart. Oh and then the ****** only right sized spring I could find was cut too short by soneone when I wasn't looking so I had to make another fiddly-arse bronze spacer for that ...
Next task is to make a setting ball ...
