Hex head grub screws ??? Don't you mean socket head ?

Roy

These have been made by watchmakers using hand held gravers for more years than I care to think about. Many driven by a bow.

Roy

Fairly easy with graver by hand

Roy

is it not the same as 0-1 ?

Roy

Do the collets belong to what appears to be a milling chuck ? Are they metric or imperil or a mixture

Roy

I have just cleaned up a thread gauge that I unearthed in my shed. It is marked Starrett No 7 there are 26 blades the finest marked 60-021, the coursest marked 4-320. there are 60 teeth on the finest and 4 on the course one.

Question what is it for ?

Clock makers usually use engraving brass, not suitable if you have to bend it

Roy

John

If you you need to bend it, engraving brass is not suitable, it will crack

Roy

I have seen a straight piece of brass shaped like a tooth soldered to the side of a wheel on a thirty hour long case

Roy

I believe the good book says " Ask and ye shall receive "

Roy

If you case hardened them I doubt that you could sharpen them after

Roy ( I could be wrong )

Clock oil to lubricate. Really should be dismantled to be cleaned properly. Could try washing the pivots with lighter fuel applied with a small paint brush ( But not really recommended )

It is a straight rod and contracts in warm weather and expands in winter ie the clock gains in summer and loses in winter . The pendulum bob is mild steel and is supported dead centre. As I said before I was told that it should have had heat treatment before I used it, and I believe that this would have been two days in a butchers fridge then left at room temperature for two days then repeated. This was from an RHS member who contacted me after I contacted them for advice

SOD

I have an invar pendulum rod that expands with cold and contracts with warming up

Roy

ps I have been told that it should have been heat treated before I used it
