Since we come back to the tubes time after time
I am interested to find out how many would like to make
an actual reproduction on reproduced tubes?

The HR1 uses Aluminium tubes

(all dimensions [mm])

inner tube  54x1        235 long
interm. tube    58x1        225 long
outer tube  62x1        222 long

A kit of all three sizes 300 long each would be nice.
Narrow tolerances are required for the outer diameters
to fit the scales, the inner diameter is less
important. If there is a felt lining as on the
original you can easily compensate for 0.2 mm.

Aluminium as the material seems preferable but not
compulsory. I would not like to have stainless steel,
it is heavy and a pain to machine.

To investigate the local possibilities for custom tubes
I have started with a firm that works with perspex.
Maybe plastic is more realistic to have in custom
dimension than aluminium? We'll see.
I will try on aluminium tubes also.

If Douglas is successful earlier it will be even
better, maybe we can get two independent quotes.

How many on the list would be interested in how many
kits?
If you want I could compile a list of all interested so
we know how many metres we will have to order ;o)
