If you are not looking for exact size, you can use 1/16" (1.59 mm) and 3/32" (2.38 mm) aluminium tubes with the standard 1, 2, 3 mm aluminium tubes.
Hi CK,
Good to hear from you mate. The reason for wanting metric sizes only was two-fold:
- much easier to calculate scale sizes when I am measuring the kit piece with a metric calliper and the piece uses metric measurements to the nearest 0.5mm.
- metric tubing will telescope precisely with very little wobble. Not sure if imperial sized tubing would allow the same tolerance.

I believe that medical needles are made from stainless steel and are probably too hard to work with - I don't have a lathe or mill, only rudimentary hand tools - but I do have a couple of Dremel type devices.
If all else fails then I would probably resort to styrene rod and tube before looking at working with stainless steel.
