  • Tecumseh Vibra-Tach -- anybody ever use one?

    See: http://www.manddsmallengine.com/tecu...ls/670156.html



    How do you use it and read it?

    I have one thats identical but the molded lettering says Treysit Drehzahlmesser Made in Germany.While touching it to a motor for example rotate the knob CCW till the wire vibrates at maximum amplitude.The upper window shows RPM and the lower shows per second.
    Mine is at least 50 years old.I have not played with for a long time and can`t say how good it is.

      Thanks. That's exactly the info I needed.

      It's the same thing with a different badge.

      I was hoping for something I could mount on an engine and just read the rpm without having to do anything.

            I just remembered this thing that I've been saving for several years:



            It came off a piece of junked exercise equipment. Maybe I can figure out a way to adapt it to the engine. I ran it with my ~2500rpm electric drill, and it goes around to the 6 o'clock position on the dial.

            I don't really need the exact rpm. I just need a easily read gage to set the engine speed for using my Briggs winch. That way my flying buddies can just set it to 6 (or whatever they've learned is the best speed for their plane) on the dial, and go. So far we've been going by the sound of the engine, and some of them have a little problem getting it right each time.

                Digital with analogue display.

                Why not use a digital controlled analogue display engine speed dial from almost any Auto store? Or from an Auto-wreckers yard?

                The kids have them on their dash for more show than go - but they should be OK - especially from a wreckers yard.
