Ahhh......  now you're talking :-)

Here is one I made earlier:

http://clive.bel-epa.com/IMAGES/Norton.gif

Even the exhaust pipe was made from scrap - it has about 6 or 7 cut and
shuts to make the curves.....  Every single nut and bolt was made on my old
1941 SouthBend lathe out of high tensile stainless steel stock. All bolts
were drilled through and the ends chamfered - nuts lockwired etc etc etc
etc.

So there must be a reason why I am still looking for a set of tubes - from
memory it was something to do with the arrangement that would be necessary
for locking the lens onto the tube and the tube onto the body without
making modifications to either body or tube.

If you have the time and a milling machine in addition to a lathe then of
course anything is possible :-)

I do still knock up the occasional alloy or brass part for various cameras,
however would rather spend what little spare time is available taking
photos.


All the best,
