Hi,

I'm not sure if this is a common way to deal with end play
in a high precision worm/worm gear situation (if it is then
sorry for stating the obvious!), but I found this little
gem in a gearbox I pulled to bits today.

You can see the thrust/ end play of the worm is
taken care of by two ball bearings trapped in nylon races
either side of one of the mounting bushes.
Slop is tensioned by the nylock nut on the end.
I thought it was brilliant and worth passing on to
ATMers / home machinists.

The second pic is the original motor/gearbox reduction shown fitted.
(I had to remove it to get the first picture)
