ohcrap, sorry to head that craig.
I bet the same was about to happen to me. I was charging this old lipo and it was defenetly the right polarity and the charger was plugged into a SLA batt also the right polarity.
But for some reasson the battery slowly got fatter and fatter. I turned it off once I realised but it looked like it was gona go so I dumped it outside.
I recorn its just an old battery.

for kwijebo i got a custom hub CNCed and fitted from UK robotics - i think i paid about ?15. The plan now is to buy a lathe, mount it in a clamp and run a drill bit through one side and out the other - tap and grub screw.
If you have the weapon and pillar drill the last bit is possible.
Any other ideas?

If you want to drill holes for grub screws the tricky bit is getting them to go though the centre of the bar. Remember most motor shafts are only 2mm dia where as the grub screws are usually M3 or 3mm. To drill from the edge of a round spinner and exactly hit the shaft hole up the centre you need a V block. This is a block of metal with a precision V macined in it. If you clamp the V block on the pillar drill bed so that the drill when lowered is exactly in the base of the V then any round object placed in that V will be drilled through the centre.
