[Obi-Wan is lost...]

I need a tiny bit of welding done on the axle of my unicycle. Yes, random I know but its a genuine request. It's quite a awkward space on the hub so the welding head would need to be quite small. I know very little about welding but I think it's just two bits of steel so should be quite straight forward. Any help gratefully received.

I have got a welder (well three actually) but not in sheff.
However should you be planning on visiting Bridestones or Widdop in the near future then I'll happily weld/set fire to your unicycle...
