Did you ever wonder what was simply discarded or burned when
in the past closed due
to changing economic conditions and technology changes?
Lots of hand tools survived but
many of other ancillary but related things did not.
My post today concerns a model set
of millwright joints used in the constructions of factories and
mills in the 19th Century.
This model set of beam joints must
have been used in training carpenters and framers or were
actually taken to job sites for reference. They appear to have
been made by a single craftsman and all were fashioned from the
same species of wood that was 1 1/2 inches in diameter.
I am pleased that I was able to
find these beam joint models to preserve and pass to others in
This is the set of eight model wooden beam joints.
Top left is a tusk tenon joint and upper right is a simple
mortise and tenon joint.
The top model is of a dovetailed corner joint and the bottom
specimen is a dovetail saddle joint.
In the set of models are three end-to-end beam splice joints
at the top to more complex T the bottom.
This photo shows the complex beam splice joint taken apart on
the bottom specimen. Bolts would have gone through the holes to
secure the splice.
