Carpenters Marks

I found this nice illustration at this blog and a piece on Roman Numeral Carpenters Marks.

I have found these Roman Numeral marking where rafters go on several log buildings I have worked on.
Usually the Roman Numerals were used in log buildings to mark rafter positions if a log building was going to be moved.

Unlike timber framed buildings, log homes were not pre-fabbed then put up again.

Regular numbers, 1,2,3,4 etc. would be to hard for a pioneer craftsman to make with the limited tools available. But with Roman Numerals you could get all the way up to 89 using just an axe, or an axe, hammer and chisel.

Just thought you would like to know.
