Hi

The photos you have shown don't really give the information
that would be needed to find or make a gear set .As it stands
the wormwheel is probably 30 dp around 60 tooth as there is
no sizes given on the worm as far as i can see.
On the assumption the the axis of the leadscrew input and drive motor
are fixed with no adjustment the only essential information needed
is the centre distance between these two shafts.

As i have had my mill set up for some months i found a scrap of
nylon and cut this wormwheel ,is 0.9 mod at 59 tooth a little
larger than 30 dp , the od at the base of the throat is 2.125 inch.
To obtain the best contact it would be necessary to make a worm
that replicates the the hob that has cut this ,this could mean the
to fit in the centre distance a smaller tooth count would be needed.
The only other alternative is to make a worm at any size that you would
need and cut a matching helical gear of the approriate tooth count
again to fit in the centre distance ,either option is just as easy.
If you want to send a PM include your e mail.
