And then there were three

I made the other 2 trucks this weekend and decided to make a short photo series of what I do to assemble the truck. I start with a simple M6 x 20mm gutter bolt tied down in the vice. I file off a 45 degree angle to make it just small enough to fit into the aluminium extrusion. Here is the resized/shaped bolt ready for assembly. Slide it in and position it to have the edge of the head flush with the edge of the extrusion. Add a simple M6 by 1.5mm washer. Notice the gap between the 608zz bearing and the M6 bolt. The 608 bearing has a 8mm inner diameter while an M6 bolt has a 6mm diameter. Add some electrical tape to form a bush. Add the bearing which should now fit nice and tight. Trim the remaining tape. Just a shot of the trimmed tape. Add another washer. And tighten it all up with a nut.   The final steps involve adding a neo magnet to the end of one of the bolts and adding heat-shrink to hold it all in place.
