Secondary Timing

so that's a smidge over 4deg per tooth.

Thanks!

Though now I am looking for a protractor scaled in "smidges"......

Down here in Florida, a smidge is .0909. Up north you have the contraction factor which is equal to the square of the hypotenuse times the slow blow hole.

And it changes out west where the temperatures are over 100F half the year! Those darn Sin, Cos, and Tan get involved.

An old fashion timing light is your friend ;)

I would have thought the smidge was a unit of measurement we inherited from the UK, and then never let go. You know, like all our other measurements.

It's kind'a like calibrating your airspeed indicator in "Furlongs per Fortnight".

I can assure you that in Scotland (from whence I originate) we never used the "smidge". We used "the thinness of a haggis's b@ll hair". Ahem...

Now - anyone want to answer my question about the mag drop?.... :-)

[Area 51%]

I don't know how you could reasonably expect a 0 rpm drop after shutting off one of the mags unless it was faulty and wasn't pulling it's weight.

Based on the semi-shielded location of the bottom plugs and a relocated flame front, I don't know if you can expect an equal drop between the two mags in the first place. That's why my money is on the 50rpm differential between the two.

Having said all that, I couldn't get the bottom magnatron wires to reach the top rear plugs without adding to the wires. So I have them firing the bottom rear plugs while the upper magnatron fires the upper fronts. So I have a more or less apples to apples comparison between the ignitions sources.

The drop is 50 on either source. The difference is 0.

I recall when building missiles, a typical lab designation for a very small dimension was”rch” or “red c_ _ _ hair”. Anything close to a “smidge”?

RPH.....rch......smidge......haggis'......frog hair.......any others?
