So I've been thinking of making some form of test bench/block to troubleshoot cars and break in motors. I wanted to use materials I had around the house and came up with something that seems to work pretty good thus far. Two 1x2 sandwiched vertically on top of a 2x4 was what I came up with based on my collection of cars. I had an old Radio Shack multimeter that died - so I used the test leads and trimmed their tops to allow for the brushes to make contact. Two small machine screws where used under the leads to raise them up to the proper height for good contact. The way the leads are butted up against each other at their bases seems to provide good clearance for the guide to slide through - while maintaining a snug fit in the process. The four felt pads on top reduce vibrations and keep the cars steady - another four taller rubber ones under the main base keeps it from sliding around. Some banana ends to connect to variable DC supply was also done for ease of testing. I applied two coats of black paint and an "appropriate" decal to try and "pretty" it up. I'm happy with it so far - took about two days to assemble (mostly waiting for paint to dry).
