I appear to have succeeded in replacing the tailpiece
The new one is metal and has four fine-tuners like this one,
I know it doesn't suit the old 'strad' but for the moment I really prefer those to fiddling too much with pegs.
Removed chinrest - I used a small nail to rotate the screw-thing, it has pads on it so doesn't mark the instrument. It's a modern chinrest.
Being very very careful as advised I loosen the strings and manages to prevent them from totally unravelling off the pegs by sticking the ends in the f holes. Removes the bridge to see clear marks (made with a very fine
knife?! that would not be by John the Restorer). I can see better now the convex side of the bridge. Takes the old tailpiece off, and the button comes off too but everything at that end looks sound. Old tailpiece, there's a monster crack/splinter at the E-string! and hurrah the tailgut is a screw job, notes how far the screws are along the thread, fits to new tailpiece, then slips it on the button.
Aaargh not sure which string is which! I'll need a photo...... ah, got the other violin out, that was handy
The fine tuners seem to be in 'mid' position so hooks up the strings, and at this point I carefully pull each peg out a bit so I can rub the shiny bits with the block of peg paste that I bought.
Put the bridge up (convex on fingerboard side?) and starts winding on the pegs. I can see the bridge will tilt over if this is done too quickly, spent quite a while doing little adjustments with the electronic tuner thing clipped to the scroll, keeping an eye on the bridge.
I like these fine tuners
That was an hour ago. Going back in a bit to check tuning and try playing - still on the first two tunes
But I'm happy I've done the job, and done no damage (the 'strad' is John the Restorer's though he said he didn't really need/want it back).
Phew!
