So you think the RH crank will foul the timing chain and ring, it does look pretty close, but I might be able to save 1mm with a change of washer so I think I'll take a punt on the Milremo cranks. Not sure what to do if that doesn't work, probably put the kiddy cranks back on and wait for my daughter to have her own kids, thanks again Bruce

This link from LollyCat shows some five pin Milremo cranks that look like they might do the job, Robc02 suggests they will fit, hopefully I can keep the same set up with all the drives on the same side. Thanks for all the helpful advice, Oliver

Thanks for the help. The tandem does have a front changer, and I was hoping to keep the feel of the vintage set up, so I am reluctant to swop all the kit and go to taper square bottom bracket. It looks like the Hilary Stone site might have the answer, there are a couple of cranksets that looked right. I'm not sure about crank length though, I guess I might need some crank shorteners, they do look a bit clunky though. Any more thoughts very welcome, Oliver

I have a c1966 short wheel base, kiddy back, lugless, Claude Butler tandem. It has kiddy cranks fitted and I want to change to adult cranks. Does anyone have some advice on this. I think I need left and right cottererd cranks with five pin spider. I might also need crank shorteners. Please see photos attached, thanks
