New Gauges

My Tailwind must be a liberal. There are nine gauges in the instrument panel and every one is a different brand. How’s that for diversity?

Red arrow: Generic auto parts store oil temperature gauge held in place with zip ties
Yellow arrow: Japanese brand oil pressure gauge
Green arrow: No-name fuel gauge that isn’t hooked up
Blue arrow: 1960’s Piper or Cessna amp meter held in place with an adel clamp
Purple arrow: Duct tape to secure the glove box

I have decided to update several of the gauges with some Bosch automotive parts as follows…

SP0F000051 – Electrical Voltmeter – $21
SP0F000052 – Mechanical Oil Pressure – $23
SP0F000053 – Oil Temperature – $23
SP0F000059 – Ammeter – $14

The first three part numbers can be purchased as a single kit which is part number SP0F000054 for $50 which is about $17 less than buying them all individually.

The oil temperature and pressure gauges will be going in the red and yellow arrow locations. I used Solidworks to design some backing plates to secure them to the panel, then had them lasered out of some 16 gauge aluminum.

Bosch oil temperature and oil pressure gauges installed.

There’s no more room in the panel for gauges so I used Solidworks to make a dual-gauge bezel mount and it will go in the blue arrow area.

This is what the finished setup looks like. I might end up moving the dual gauge bezel a couple inches to the right so that it’s perfectly centered to the panel. The reason is because the tip of the pilot’s control stick makes contact with it, but only under full down elevator with a fair amount of right aileron. I can’t imagine a scenario in which I would be applying enough forward stick to make contact with the bezel. I’m not sure what the FARs state in this aspect. I know for a fact that I’ve never applied full forward or backward elevator in flight. I don’t think I’ve ever applied full left or right aileron in flight. The Tailwind’s flight controls are very light. They do not need much input because they’re incredibly responsive.
