Last time I talked about how to create exactly parallel rods for sliding machine axes. To make it a bit more clear, Sean (another Media Labber), my Aussie friend Owen, and I created a quick video that shows the construction of a Mantis 9 Y axis. Check it out...
As much as I'd like for it to, not everything goes to plan in these videos. Here's our first blooper.
More videos soon.

Goodness, I wondered what you meant when I first read it. I thought you meant you drilled your holes through both pieces at the same time, and I guess you do that as well. But you do the same thing I did with my plastic slides, nylon 1/4 on 1/4 steel rod with some white lithium for lubrication. Nice video :)
ReplyDeleteisn't drilling both holes at the same time negated when the board is rotated to make the "s" shape?
ReplyDeleteI like the use of epoxy to ensure good alignment of the bushings. A few of my experiments had alignment and binding issues. Someone on hackaday.com commented that the epoxy could break. While I haven't built your machine myself, I'd be concerned about this too. One solution might be to put the bushings in a small block of wood. Then epoxy the block in place just like you do the raw bushings. Once that dries, you could use fasteners for additional strength. A few extra parts, but possibly more durable.
