Help with Tandem crank

The pedals would also unscrew themselves on a regular basis, which is why pedal threads are handed in the first place.

 

(If you're a geek or an engineer, google precession)

This could possibly be fixed with Lock tight (If you want to go with the eggbeater option)

with regards to the pedals swapping, can you not just swap the pedal axles around in the pedals?

No, because the left arm is the one with the spider to which you fix the chainring

If you don't use your small granny gear then do what we did. Moved the interlink chain to the right side and put the interlink on the small chainring. Use a normal double crank up front with just one blade and a triple ring crank at the rear. Did have a few alignment issues initially and also had to change from newer bb's to the older style ones. You can have a look at it at kremetart next weekend.

I am considering this, but after this years Panorama I value that granny gear very high

If both the axel and crank were of the same metal, I would have welded them, but unfortunately the one is alu and the other steel
