Hi All,
I want to fit a clock movement to a gramophone record.
I will need to open up the hole in the middle just a little?.
Shellac is known for being a lot more fragile than vinyl.
Would people recommend.
Sandpaper?
A file?
Or a Dremmel?

A shallow cone of sandpaper wrapped around a dowel and run in a drill?
something like that, yes. shellac will melt and it will dissolve in meths...
I haven't had to do it, but I'd try some abrasive paper on a tapered reamer. What size do you want to go to?
Yes from both sides. I still say though that given the age of 78records actually made of the stuff they are become more brittle with age, so it might not be a very long lasting clock. They did towards the end make them of vinyl you know. I had seen Parlaphone copies of the early Beatles singles on that format. Brian
Shellac is thermoplastic so maybe enlarge it with a soldering iron tip?
Try a tapered hand reamer, you would need to go through gently from both sides alternately, until the correct size hole is established.
