Getting Narrow M... ähh... Gauged

[Schraddel]

Hello,


Fitted new softer springs from NWSL.





The gearbox get it's torque lever.
Then i reassembled the running gear and tested it by pushing onto a glass plate and track. It was running smooth without any binds.





The other end of the lever was attached here. Drill and tap and the screw.





The new motor was fixed by glueing into place. Universals by NWSL.





The pilot was spring loaded by an self made coil spring. The trailing truck got the same treatment.



The come test running ...       
No Messr. United this is not the way gearboxes should run.
In backwards direchtion it moves under own power, but a very loud gnarling noise. That was the good news
In forward direction it blocked itself. That is the bad news.
Why? 




 
The gearbox was removed again and examined carfully.
Bugs found:
- there was not a correct mesh between worm and worm gear
- cause: the half bores for the driver's axle were not in line
- one has the correct depth for correct mesh
- the other one not
- as said before Messr. United, this is not the quality level we are accustomed from you

Now a thouroughly and cautious filing by me followed to establish the correct mesh with these mod. 0.3 gears.



The running gear was reassembles again.

And now it runs like it should:
