motor advice for rotating crt setup
bfauska:
Getting a cylinder to bind is all about the angle of travel, in the drawing shown the cylinder rotates a total of 9 degrees throughout the course of it's move. Again I don't think that it's the best way to go in a cab, but I have NO doubt that it would work. I've done bigger, realworld, and the problems I've had are more about the uneven power transfer of a compressible gas. If you look at the cylinders on most heavy equipment they are almost always converting linear motion into rotary, they aren't causing things to rotate in an obvious fashion but they are are pivoting around a point.

Makes sense. My stuff is small, and the cylinder ends up swinging something like 35 degrees.
You need to stop trying to talk him out of pneumatics and talk him into using high pressure nitrogen.
We need more amusing "hold my beer and watch this" videos. :)

At least my stuff aint small....

Yeah, over the course of a 35 degree cylinder pivot the load changes dramaticily, I could see that being a problem.
I suppose I could try to convince him to use CO2, if you regulate it way down it actually makes a good compact tank for a system that needs many cycles between charges. I totally agree that one of the things this forum has too few of is "hold my beer and watch this" videos. :laugh2:

After Ed's comment about the videos I was already chuckling, but that put me over the edge, good stuff.
