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 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 (...) (18 years ago, 22-Dec-05, to lugnet.build.mecha)

| Hey Danny, thats interesting. You may be on to something. I'm wondering, when a corrective tension is added (turning the opposing gear) the center of the axle will twist. Also, because the two drives are linked with z16's, when you turn one, the (...) (18 years ago, 22-Dec-05, to lugnet.build.mecha, lugnet.technic)
