The Cable Tie Track Trick
I had another nutty idea all of a sudden. Would cable ties work as a precision track? So I rolled a very funny-looking gear by hand and found it might. I put a section of it in the jig we use for making Darwin gears, and it came out a little strange but definitely worked.
As you can see, I didn't break the jig or anything - the polymorph (yes, I dyed it black with candle soot) was just a little too cold. Stabbing it with the wrong size screwdriver for a shaft didn't help either. However, it is getting late and I must away. And soe once more to bedde...Vik :v)

High-rise RepRaps
I had a daft idea the other day: It started off with a double-decker RepRap, and ended up with a vision of RepRaps in a 19" rack frame. The RepRap below was building the RepRap above...
In theory, RepRaps should work upside-down or even in zero gravity. The extrusion is forced out in contact so doesn't need to fall anywhere. So, time to get 2 Darwins running simultaneously in the workshop and then get creative with some 2x4. Anyone near Auckland with an unused 19" rack who really likes RepRaps?
