Hi all, i have reworked the shaft. There is another support and a universal joint. Its hard to see but these are uni joints supplied by hollywood foundry. The mechinism still needs a good run in. need to build track. there is a piece of lead on top for traction. this will be replaced by the boiler and side tanks.

a few more images so far, the cylinders need to redone as there isn't enough clearence for the rods. i will increase the spacing by 0.7 mm from the centreline.






hi all, i have reworked the design of the rods and cranks to improve the assembly. the centre photo shows the jigs to press the wheels onto the axle muffs.

hi all, a few more recent shots of the Na. the last photo shows the motor in the background.
the chassis is free rolling at this point. This design is far neater than the earlier one, assembly is simpler too.
