Shardlow micrometer adjustment

[grim_d]

Hi all,

Recently bought a nice little shardlow 0-1" mic from a member, i like the shardlow ones because they have half thou increments on them.

After a clean and lube it works nice but it's half a thou out. Usually there's a little hole on the barrel to use the setting spanner to move the barrel to set the zero but not here.

I've gripped the barrel with soft jaw pliers and tried to move it without success. Don't want to force anything without knowing better.

There's a grub screw on top but as far as I can see all it does is plug the hole that the pin for the lock comes out of.

Anyone know the secret or is it just seized?

I missed this post Graham, my Shardlow 0-1 Vernier Micrometer below. My spanner is not correct for this micrometer other than the C end fitting correctly, I think it is a Moore & Wright spanner. Lovely micrometer, hardly use it now and seems to have developed a small rust spot on the anvil but still good considering it was secondhand and I was 15 when bought so I've had it nearly 40 years.
