Thanks to Michael and Hopper I'm not alone in thinking this is useful.

I had to check and yes my chuck does have a logo. I think the reason I didn't think to use it is because when I am centering work in it, I am standing in line with it and can't see it ( it is a 12" chuck). I am going to mark it and I am going to use the A1, B1, A2, B2 which will pair the jaws in a way that my addled brain can deal with.

David.

Just pulled apart my 1920's Burnerd 4-jaw and found it has the jaws numbered as well as the slots. Makes a big difference to the ease of use, as after first cleaning i mixed up the jaws without realising it and couldn't understand why some were so stiff. Now i know, works a lot better now.smile

My 4 jaw is simply numbered 1 2 3 4 in rotation, even numbers one pair of jaws odd numbers the other.

easy to remember when your in a hurry.
