When I was building my Sierra race car, I needed to bead
the aluminium for the interior. Not knowing how beading was
done I went to a machine dealers and asked if he had a beading
tool for sale, so I could get a look at how it worked. The
bloke said "you need a jenny" he dug around in a
pile of what looked like scrap produced a thing that resembled
a heavy duty hand drill; he told me "it needs rollers
and a new handle, so you can have it for £275",
if it had been £20 I wouldn't have bought it. I didn't
really get a look at how it worked before it was chucked back
in the pile of junk, something to do with me laughing?
I new that it used rollers so it was fairly obvious that
I needed to roll the metal between two rollers that had the
required bead on the radial surface and were driven at the
same speed, in opposite directions. That's about all there
is to it.
The beadroller was used on racecar interior, 22 swg ali and
16[drivers floor]swg ali; I also used it for stepping repair
panels for cars, so it also worked with 20 swg[?] steel. I
would include a picture of it but 10[?] years behind the polisher
and it looks disgusting. Figure 1 and 2 are renderings of
the autocad drawing of it, yes I haven't mastered rendering.
i.e. views, if any dimensions needed etc.
