gear drive info?

[edwalsh18]

I have a question for the guys that have made the gear drives with servos for hydraulic rams.

I would like to know how many rotations per stroke and how long stroke is in inches and time it takes per full stroke.

The reason is to see if I can change up the components a bit to get similar results. Like maybe using a geared motor instead of servo and a nut and bolt instead of drill bit. Servo is slow so bits need to have fewer "threads" per inch. I am hoping I can get some info on that setup to find something similar but a little more speedier. Any info will be appreciated. Thanks
