Mechexperts: I'm working on a secret [read:unworthy] project and have been trying to think of achieving a certain type of motion without success. I'll try to describe it: The motion/mechanism I'm looking for needs to be able to achieve some sort of (...) (22 years ago, 7-Aug-02, to lugnet.build.mecha)

i to have had a similar problem involving a scaled-down version of some of the big mech joints, and your problem has reminded me of a version i scrapped a few months ago. try getting some of the flex tubing that can be found in the anikins podracer (...)

Luke, I'm stummped too! Although I'm just not sure at what your trying to accomplish. Maybe these two pix can help. I use a Cam Mechanism to achive linear motion. The end out put is a controlled recipricating motion. see the pully wheel behind GG's (...) (22 years ago, 8-Aug-02, to lugnet.build.mecha)

Interesting solution! I had tried the long pins and found that the end I wanted to stay stayed for the most part...but it wasn't reliable. Increasing the friction of one end is a novel idea indeed. I may just use it in the end. The option of making (...) (22 years ago, 9-Aug-02, to lugnet.build.mecha)

Interesting! Up until now, I had categorically dismissed all non-discrete forms of linear motion. Cam mechs are a wonderful idea! I gave them a try though, and sadly, didn't work out as I had hoped. As always, space-constraint was the issue. Don't (...) (22 years ago, 9-Aug-02, to lugnet.build.mecha)

(...) I think this is a great suggestion for what Luke is trying to accomplish. Just place the tubing in the center of two long friction axels. If flex tubing gives you too much flex, you could alternatively use the 4L lightsaber blades in it's (...) (22 years ago, 9-Aug-02, to lugnet.build.mecha)
