c?rt is right, but at the essence of all this chat
is the issue of "who" is the audience here. full
time slash career builders "need" a table because
it improves efficiency, and improved efficiency
improves everything else. but it has been shown that
this list is mostly home-builders with day jobs,
most of whom are not producing/productive framebuilders.
curt is right about suzy being right about folks need-
ing an entire skill set long before they need the heavy
tooling with which to measure the innacuracies that are
part-of-the-job when you make 2-8 frames a year. the
o.p. asked about tables, and my opinion remains that
they (tables) are not only unnecessary and an expensive
luxury, but they'll give you the false sense of security
that if you fail along the way you can simply put it
on the table and tug. all metals yield differently than
each other. same for b.b. shell castings. just because
you find an error by measuring it using a table, you're
more likely to screw the frame up by leaning on it unless
you've used "that" steel and "that" b.b. shell many times
and have the hand-feel to know what bends where when you
start tugging on it.
