Hey guys..this one should be obvious but I'm just checking.
I'm about to order a cylinder to use as a lift cylinder for my bandsaw as John showed in another thread.
The place I deal with seems to sell pretty nice cylinders at a reasonable price.
However...they only sell double actling air cylinders.
So...the end you are not using...do you just put like a filtered vent on the inlet port to allow the air to go in and out as the cylinder operates?
Thanks!

Russ,
Mine is a double acting it's just left open, sure I now know I should stick a filter in it :D

You can stick a regulator - basically just a fancy needle-valve - in the "dead" end of the cylinder, to control the rate at which the cylinder actuates.

This is the usual way of regulating the speed of excursion, and much more controllable than adjusting the flow of the input air. It'll help keep the cylinder from slamming the saw upwards. Ask the folks where you're going to buy the cylinder - these things are pretty cheap.
