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.

i finished the drive to the spur gear. runs well. I was a bit worried that the reduction on the g15 motor was going to bo to slow, but it looks ok to me. sorry the video is a bit blurry.

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.
