A simple animation rig can be made with some simple items.
- Some rare earth magnets
- a few K'NEX rods and connectors
- a block of any material that you can drill into
To get maximum holding power and maintain ease of use, I chose one inch diameter by one eigth inch thick neodynium magnets. These will hold my robots in place and are not too diffucult to remove from the sheet metal base.
For aesthetic purposes, I chose to cut my base block on the CNC out of some 3/4" scrap phenolic sheet I had laying around .This is the same material that high end router table tops are made out of. However..... A simple block of wood will suffice.
It is important to use slightly oversized straws like the ones you can get from Harvey's. They are slightly larger than 1/4" diameter and K'NEX pieces will fit inside them perfectly.
