Warning - I am about to databurst again...
I can see what eric says about the counter system - and I wander if if
could be simply overcome by having a set of two worm gears meshing
with a set of two 40t gears on the same axle - you can have the worm
gear axles linked so you can do the large adjustment together, and
then take advantage of the backlash of the gears in the system
connecting the two worms to turn them slightly against each other to
oppose the backlash on their link with the 40t's. This would then mean
it could be used without having to take it into account as part of the
balancing of the creation.

To try and save peoples brains from bursting - I went and had some fun
with MLCad and LPub:

I've done a similar solution however:

I put 2 worm gears on 1 40t gear. One on top and one on the bottom. My intent
was to counter the slipping that happens under severe loads. Though it's a pain
to turn (you have to turn 2 axles in opposite directions) it works well.

That said you can do the same function as your idea above by turning one and not
the other.

Hi Brayton, While erics reply is pretty comprehensive, have you posted to .technic to see what they have there? Warning - I am about to databurst again... I can see what eric says about the counter system - and I wander if if could be simply (...) (18 years ago, 22-Dec-05, to lugnet.build.mecha)
