Thanks!
I won't be able to get a picture of the axle until tomorrow evening (it's at a shop) but do know that - to accommodate the drum brake - the axle is thicker in the middle. Once I pick up the axle, I'll take some calipers to it...
I'll have a look for hubs. Are there any that you'd recommend with a drum brake that would accommodate a six speed shimano cassette? All those that I've seen have internal gearing (there's nothing in the Tester Approves thread).

Picked up this Chris Paulson tandem from a forumer a few months ago (it's a beaut!).
I took it out on its first >10 mile excursion and the rear axle broke (no one was hurt). I suppose this is to be expected from a bike of this age. Unfortunately - as with everything else on the bike - the axle size is irregular. I've been to my LBS who've stated that the options are to 1) Replace the wheel (maybe losing the drum brake?!) 2) Re-weld the axle, or 3) Get a new axle machined.
My preference is currently 3 (2's a non-starter as my gf will be on the back). Does anyone have any experience with getting a new axle made? Are there any metal turners that you'd recommend?

5.38 (probably about 6 including stops) on 48x17 gearing.
Day was marred by an incident in which the other party cracked his carbon frame. I don't believe I am at fault and the guy - rather decently - refused to take my number at the time. But if the other guy is reading this and would like my details, please pm...
I was the black guy on the cinelli mash.I don't really go on any other cycle forums, so if anyone sees anything, feel free to direct them my way.
Thanks!

Guys,
Thanks for all your help. I think a new wheel is out of the question because the current wheel size is 32-630 (27 * 1 1/4). - Is now the time to change this?
In terms of my preference for a screw-on 6-speed freewheel - I've had very little (no) experience with gears and am aware that nearly every part on the bike is bespoke, so thought the best options would be to try and keep as much of the wheel constant as possible. As has been alluded to upthread, this will likely mean slowly changing every part of the wheel in succession as it fails...
So... my next steps will be to determine whether my current drum brake is screw-on and to buy a new hub. Given the potential for a catastrophic failure and my wish to do some light touring with my significant other on this bike, I think it makes sense to change the hub.
@mdcc_tester - Thanks for your kind offer nonetheless.
