Final Design Commit: Triceratops Two

Image
This is the beast I'll be building as the weather in Melbourne begins to improve with the impending spring, the Triceratops Two. For now, T-One is DOA because I think there will be less tweaking involved to get the tracking aligned on T-Two and the cornering will be as tight as a road bike under Cadel Evans' captaincy. The preliminary OpenSCAD code for the design resides on my GitHub.

Bunnings Ozito MIG Welder... DOES NOT WELD ALUMINIUM!

Image
I bought one of these and love it. Great welder for steel. Really pleased with my purchase, but I bought it to weld steel, so it really is a great little unit for THAT job. (Building my first trike, which will be steel.) I bought it from Bunnings online, Linda did the collect and when it got home, on the box it says it can weld steel or aluminium. You can imagine a maker like me would be pretty stoked by that, so I checked out the manual before looking at any other part in the box. The manual has this to say.. The problem is, flux cored aluminium wire, at 0.8 or 0.9 millimetre, is actually unobtanium. There is no such thing because it can't be made stiff enough to not jam or crush in the wire feed pinch roller. Ye cannae change the laws o'd pysics, Jim. To claim this welder could weld aluminium with aluminium cored wire is not only a misleading statement, it's possibly quite dangerous. What you can buy is 0.9mm aluminium "solder"/brazing wire, which is only suit...
