Anybody know anthing about this Tippett Timer. I found a case of these at a swap meet but have not been able to find anything about them. I would guess it used the compression stroke to move the indicator up to TDC. Any info would be appreciated.
It looks like it actually is put in series with the high tension spark plug lead. But then what? You mentioned you found a case of them, surely one of them has the "Complete instruction" in the package still?
A newer version of the same tool? Both say "Time Rite" From: www.aircraftspruce.com Time-Rite is an instrument designed for precision timing of aircraft engines by direct measurement of piston travel.The features of the Time-Rite design a moveable slide pointer, and an adjustable calibrated scale, eliminate the need for finding top dead center and compensate for the variables involved in accurate piston positioning. Calibrated scales are available for most types of engines, and scale calibrations are obtained in cooperation with, and are approved by the engine manufactures. Because of the difference in spark plug locations and piston dome shapes, different pivot arms are available to adapt the Time-Rite to most aircraft engines. All arms are easily interchanged. Carries a Lifetime ATS-Pro warranty The complete Deluxe Combo Kit contains everything needed to handle every engine listed in the timerite manual. Engine Information Install Time-Rite in the spark plug hole of the timing cylinder and turn the engine through one complete cycle which leaves the slide pointer at the highest piston travel point, permitting alignment of the zero degree position on the calibrated scale with the slide pointer. Timing degree positions measured from the zero degree scale mark represent angular, crankshaft positions relative to true top dead center as obtained by methods using a pointer and protractor on the crankshaft.
It is basically an indicator like a dial indicator you would use when degreeing in a cam and finding tdc. Just for after the heads are on. And it seems you can then convert piston motion to degrees crank rotation to be able to set the timing.
Where does the short piece of high tension lead come in? Is it a red herring that actually doesn't belong with the tool? And no, I didn't read the four pages of fine print in the patent application.
