Well here's a right todo and no mistake. I've just started putting the return rollers on and the roller mountings are 5mm too low. This means that the road wheels will hit the return rollers....

Oh B%^^#r!!!

That means a strip, redesign and reprint of the four suspension units that have return rollers in them. Wayne I do hope you haven't attached them to your hull yet!

Oh well back to stripping and rebuilding!

Thanks Wayne. The problem did not become apparent until I attached the return rollers on either side of the centre suspension. Of course with the front and rear suspension it wouldn't have been a problem as the return rollers sit between the road wheels as on the Chieftain, but the Centurion has, believe it or not 6 return rollers on each side as opposed to the chieftains 3.

Bother and Damnation, I hate redoing work and especially the 6 hours of reprinting that will now be required for the modified suspension. At least I managed to remove the old suspension without damaging the hull by careful use of a large blade and a couple of thin screwdrivers.

Ho hum the joys of scratchbuilding!

Another beauty taking shape quickly, Alwyn. I was interested to read about how you orient the print for strength, I've wondered how strong and durable the printed running gear would be (particularly if they're not completely solid). Looking forward to seeing more!

[AlwynTurner]

Thanks for the good words guys. Regarding the durability of the components I have been obsessive about the thickness of the components and the direction of deposition when printing. Whenever there is going to be lateral stress I have tried to design so the component is strengthened by a bolt, for example in the swing arms of the suspension. Only time will tell, but on the Chieftains outing at the LAD meet I ran it for about 10 minutes with absolutely no problems. I am confident the the sprockets in particular will hold up as they are heavily over-designed.

Hi Wayne, sorry I didn't pick up on the tracks/gearbox question. I am using the KV1 track

same as the Chieftain with the edge wings trimmed off and the gearbox from Forgebear is the standard Heng Long long shaft gearbox
