Rough gas pipe router, absolute accuracy not hugely important. currently 5/16" -18 all thread 42" long. Stepper 127 oz in, 200 step per rev, which torque falls off quickly about 800 steps/second. Budget is a consideration, but I'd like to get to 2 or 4 pitch leadscrew rate. Is there a reasonable cost method to mechanically multiply via gears or pullys. Or do I bite the bullet and replace with new leadscrew? Is this
www.mcmaster/com p/n pair: 99030A716 screw and 6350K153 nut a reasonable solution?
