Re: Robot Pit Lift

Kevin and Sanddrag,
The motor speed device is listed for AC/DC as series wound motors will run on both but at 120 volts. If you look at your plugin drill it may say AC/DC. (Parts of some cities are still running DC in older sections. Milwaukee is rumored to still have buildings downtown with DC, for instance. )
A rheostat will work but it's value must be matched to the load impedance or you don't get any control. Just on and off.

Re: Robot Pit Lift

We've got one on our cart - it creates a more elevated workspace for us. Four 8" throw pneumatic lifts.

Haha, honestly I don't think we've ever tried to weigh it.

You can use the white needle valves ( the ones with the thumb wheel on it that was supplied in this years kit to control how fast the cylinders fill. Or you can use SMC controll valve or the ASV Speed Exhaust control
As to the issue of multi positioning the lift you could use one of the designs in this thread Multi positioning pneumatic actuator
