rec.crafts.metalworking. The old-tools enthusiasm that's common amoung
woodworkers doesn't really seem to exist amoung hobbiest machinists,
tho (they tend to have more enthusiasm for old steam engines & such
like, rather than for the tools that built them).
I think it was probably custom made, it's a little sharp on the edges, not
for cutting but from not being sanded (don't know the proper machinist term
for that) and the points are fairly sharp. It's just less than 1/16" thick
and a magnet will stick to it but not very well. I bought it at the flea
market from a guy who sells nothing but tools, it was in a box with a lot of
calipers and micrometers. Don't know if I'll ever find the answer to this
Also I'm not sure if I'll ever know where #146 came from, it's that piece of
metal that says "shut" on both sides. Maybe someone will remember seeing
one years ago.
Thinking way back, the small town (< 100) I grew up with had a small
feed mill. There were dampers and valves throughout the mill which
were activated by pulling on a rope (the valve/damper may have been
20' or more up). Perhaps #146 was attached to one of these ropes
(and there was one that said "open" for the other end of the rope/chain).
I've found things in boxes of machinist tools that I thought were
maybe learning/skill developing projects--something a student would
have made to study a particular technique, or something made for a
particular, one-of-a-kind operation.
The book mark or paper clip worked for me until I noticed that it appears to
be too thick to bend easily as might be required for a book mark. Looks to
be stainless steel also. I'm sticking with ball mark repair tool ..LOL
I've found a lot of enthusiasm for old machines, but there are fewer usable
ancient lathes etc. than woodworking machines, so less discussion. FWIW I've
found woodworkers know less about their tools.
Ya know . . . I always assumed that metal turning was "invented" during
the machine tooling explosion of the 19th Century, thus accounting for
the difference between metalworking lathes versus woodworking lathes.
19th Century machining made the Michaelson-Morley experiment possible,
which called into question the existance of Diethlerous (sp) ether,
which lead to Einstein's Special Theory of Relativity.
I imagine the power source would have been much the same as on
comparable woodworking tools, but I've never seen a woodcut of an old
