Talking to "The expert" down the pub who reckons the case hardening on valve shims is 10thou thick on each face. He said hes never bought a shim in 25 years, he just grinds 1thou of at atime until the shim is the correct thickness.
Anyone else heard of this?

That's all well and good except when you need a thicker one. For the sake of £4 I wouldn't risk my engine on a home ground shim even if I did have a grinding machine.
The shims are 25mm daimeter and sit on top of the bucket. Old XS & XJ Yams are 30mm. To shim mine over winter, I took off the cam caps to lift the cams slightly to get the shims out. Saves spending on a special tool.
