anyone else seen that program, How It's Made? I love it, but the
edition where they were building a carriage blew me a way! The
carriage body was welded from square pipe which was no
particular surprise, but the construction of the wheels was
felloes were laid out upon a flat steel table in their correct
position, then a steel hub was bolted on top and through them.
Then the ends were cut to length, chamfered and tenon cut by a
powered version of the appropriate handtools.
They used two rim
sections which were pneumatically pressed in place, a rim was
welded and I missed a part about something being soldered. The
the tire was dropped up and down until the rubber tire seated
itself. Somewhere along the line it got a coat of white paint.
What astounded me was the pneumatic table with pre-spaced bolts
and the ease with which they just slapped together a wooden
wheel. There was no dishing, no wooden hub, but the process was
sort of a bastardized version of a carriage wheel. The process
was meant for mass production, but I wonder how these wheels
hold up? They use Ash for the spokes was the only wood
wonder if these town-used carriage wheels aren't meant for a
short lifetime? I cannot see how the hub bolts in wood would not
eventually elongate or break out. Of course, it wouldn't take
much to de-construct and repair the wheel or just toss it and
save the hub plate, if even that!
had no idea that a carriage wheel could be built that fast with
so little labor and even less wood! They have found a way to
automate a centuries old process that just sort of shocked me,
but maybe I'm the only person who wasn't in on this
