wooden repstrap

I have accomplished more the last couple of weeks than I have accomplished in the three years that I have been "playing" at making a repstrap.

What's a repstrap. Go look at http://reprap.org/wiki/Main_Page and you'll know what a reprap is. A repstrap is a way to make a bootstrap of a reprap. Had made something that can then make the parts for a reprap.

Here's a video of what I've been working on: http://www.youtube.com/watch?v=q5N5D4YhE_Q
and here I hooked up a rope drive to it.

It's been going through several renditions and has been taking on some complications to get rid of wobble on the z-axis. Have made changes to the y-axis too. It now uses skates as show in the video. The green plastic that I thought would be slick enough to not use bearings wasn't. Went with skates that I first saw here: http://www.instructables.com/id/Build-a-CNC-Router-from-Scratch-Part-1%3a-Complete/

Mainly because I already had six of them built from attempting to make one of Daniel's cnc's. Too slow using 1/4-20 threaded rod. Same problem I have with the McWire here: http://www.instructables.com/id/Easy-to-Build-Desk-Top-3-Axis-CNC-Milling-Machine/

I have a very detailed drawing done in Sketchup here: http://dl.dropbox.com/u/4861696/Wood-repstrap.skp

As you can see, I've been working hard. The next weeks are going to be interesting.
