The Tachometera did indeed have two hands. One was stationary and attached via a knob inside the glass so the user could set a reference point similar to later tachs. The rest of the unit is nearly identical to the speedometer internals. I have three or four of these in my shop and one of the right angle adapters. But have never seen the generator itself as big Kev mentioned.

Kev, All,
My speedometer biz soace is C4Q-28 in chocolate north. I don't spend all my time there, however. Like most of you, I am also looking for goodies in the flea market and hope to meet those of you i havent before in the Packard area.

What 39 Six parts are you seeking?

Wheelhorse, all,
As Kevin pointed out, the small brass cup and wick allow a lubrication point to the input magnet shaft. It is important to keep this lubed as it gets quite a bit of rotation, thousand RPM at 60 miles an hour.
However, lubricating this point will not correct for a weak magnet or other obstruction keeping the pointer from moving to an accurate speed. Also deeper inside the speedometer, the odometer geartrain also can suffer from old dry lube. Unfortunately the engineers never figured out a good way to provide lube to all those different internal points from the outside of the unit.

Regarding the cable, although graphite will not hurt it, originally, the rotating inner core was given with a thin coat of grease; you don't want to pack it in or pump it in from the bottom. I've repaired many speedometers of which somebody had pumped grease up through the transmission and and all the way into the speedometer making one amazing archaeological dig for me to explore. A little grease is all you need.

I hope this helps, Pat

I'll have my speedometer biz space in Chocolate North (but will be scouring the meet for Packard, Hudson and Speedometer parts!)

It appears the hub of the pointer is within the speedometer, but arm of pointer missing.
If this is an AC unit, the pointer is available (I believe I've got them in stock, unpainted).

Great progress Kevin. Getting glass done is a great step. Same for woodgraining. That dash is gonna be b-e-a-utiful.
