    Hi, Just a quick question about old fashioned carpentry terminology. While looking up some ancestry information, I found an entry for my grandfather from 1905 that refers to his occupation as a “mounter”. Since we live where there were railroads, timber yards, canning factories and founderies, my assumption was that this had to do with carpentry – via timber yards. Do you think this is related to woodworking of any kind?

      Hi Laura,
      It doesn’t ring any bells with us, it could be a term unique to where you are located (are you in the UK?)?
      If you’ve got any more information then let me know and I’ll do my best to help.
