Proof of Track Idea

Rob got a chain! He went down to the tip yesterday morning and because we only want the chain (not the whole bike) he managed to get one for free! The plan is to use a segment of this chain as a test piece to prove the idea.

Rob ground the ends off the axles and we used a center-punch and hammer to pop them out, completely disassembling the segment of chain.


We reassembled the chain by replacing axles with long nails and placing (over-sized) spacers between the chains.
Obviously these spacers are way too big, but just to give the feel of what it could potentially look like.


Looks tough!!
If we can get some long mild steel axle (instead of nails) from a steel shop and cut it down to size, and find some sort of spacers (steel or even plastic should be ok) that will be all we will need to build the tracks as we planned.

The fall-back plan can always be similar to that instructable which doesn't involve disassembling the chain at all and just drive it from a roller-blade wheel or something, but we think this was would be cooler :)

To make the tank look real-ish, the ratios have to be proportional.
The length of the chains and the width of the spacers is going to depend of the overall size of the tank. This means we have to work out what else the tank is going to house (air compressor, etc.) and help from Google Images will be useful!
