Poor man's Hobbs meter setup

[radioguy41]

Trying to find an NOS period correct Hobbs hour meter with zero hours for the Cub and not go broke can be a test of one's endurance so I came up with an alternative. Hobbs made nearly identical meters for the airplane industry and they can be found, if you hunt a bit, for a very reasonable cost. The major difference is they only go to 1000 hours, not 10,000 as the original but since there's no chance I'll ever exceed that, and I still wanted a meter that looked period correct, I bought an NOS model MI-261 (6 volt) aircraft style. However by the time I got around to finding a bracket and mounting it I had converted the Cub to 12 volts. It's the law of unintended consequences at work. What to do? Well, I found this nifty little gizmo on Amazon, a tiny voltage converter; 12 vdc in, regulated 6 vdc out. Nothing special, just a make-do fun project.

As purchased.

Oil pressure operated switch.

Voltage converter.

Shelf to hold the voltage converter.

Voltage converter on the shelf.

Mounted on steering support. I made the rubber support from a 1/4 inch sheet.
(Haven't tidied up the cable yet)
