Anyone know a source? Very very light torque and no precision requirements at all. Simply need to transfer perpendicular motion to eight separate rods along the length one threaded rod. Am considering a few other options such as .25 pitch spring as worm and 25p sprocket as gear. Hard to source a dependably pitched spring of a useful (for my purposes) diameter. Also considered an acme rod and thin spur gear of same thread/tooth pitch but it gets expensive for this little experiment.
Optimal would be a 1 to 1.5 inch diameter gear that would mate up with standard (cheap and available) 1/2-13 threaded rod. Precision is NOT necessary. Thrust angle, wear considerations… not a problem just as long as the gear turns with/by the rod.
Any suggestions please?
Thanks
