97.0. "clutch anyone ??" by BZERKR::DUFRESNE (You make 'em - I break 'em) Fri Mar 20 1987 16:33

    Ok.. this one is for the car freaks out there:
    
    	I am going to build a simple minded dynamometer to measure torque
    and RPM for my project (see note 93) 
    
    We have the torque watches. I need a clutch. I know that some cars
    are gas powered. how do you guys transfer power to the wheels ?
    
    I would find hard to believe that one just fires ups the engine
    and keep the wheels off the ground until you ready to roll.
    
    So ??
    
    tx in advance

		Centrigugal clutch,well that's what stops the 
	rotors on my helicopter removing my kneecaps.


		'Spect cars are the same.

    hobby shop ??

    Went to hobby shop today.. bottom line is that cars & helicopters
    use same type of clutch: centrifugal.
    
    Kyosho is apparently the only mfg of gas powered cars. The parts
    catalog gives clustch in pieces, not as unit. And there is no parts
    explosion diagram.. I guess I get to call Great Planes ..
    
    Unless.... Its there someone out there with a car or heli out of
    commission that is willing to donate a clutch assembly to worthy cause??

    RE: all
    
    Are you sure that a clutch is what you want?  Most Dynos. use a
    brake.  The brake drag is varied to set the RPM at which to read
    the torque.  A centrifugal clutch will just lock up (engage) above
    some RPM.  Are we talking about the same thing?

97.5yes we are..I thinkBZERKR::DUFRESNEYou make 'em - I break 'emWed Mar 25 1987 13:226
    after some research, a centrifugal clutch may be what I want.
    
    I'm back to my orignal problem: DOes there exist a inexpensive Dyno
    set-up that I can use for my engine ?? Do they exist at all ??
