Today James (left) and Jason (right) finished mounting the rear wheel and differential assembly into it's new position.  The v-belt now connects the engine and the drive gears directly and the idler pulley was relocated to where the clutch pulley used to be.   This allows the clutch to tighten the v-belt to engage the rear wheels rather than release tension from v-belt.    When this was done, they lifted the completed drive train into position and began planning how to mount it to the vehicle frame! 

Meanwhile, Nicky finished his steering mechanism.   He found a geometry that seems to give a good amount of leverage to the driver and made a clever use of drilled strapping to tie it all together.   Strapping has great tensile strength, but not a lot of compression strength... but by putting strapping on either side, one side is always under tension.   And because the steering wheel and front wheel linkage are not in the same plane, the strapping seems to provide just the right amount of flex to allow the connection to work well.  Tie rod ends?   Who needs them?  Way to go Nicky!Nicky had to weld together two pieces of the 1 1/2 inch square tubing to get a beam long enough for them to support the engine and then James and Jason took over and cut this long piece to the correct size.
