not much added to the NA but i have had a go at some trackwork. the points are 5mm gauge.

there made by hand using code 40 micro-engineering rail and nn3 pcb sleepers from fast tracks.

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.

latest revision of a hon30 NA loco.

something else in the works,

a hon30 version of below. just a rough drawing to see the suitability of off the shelf motors and gearboxes.

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.
