[CAUT] buzzing truck

[Fred Sturm]

Ditto on the swivel cups. And since you can't access the slotted screw  
head, you have to swing the arm away to tighten (lift under that leg,  
having braced under the other two legs - wooden wedges under the truck  
ends). It can be done pretty quickly with the stuff all gathered  
together, especially with a jack-in-the-box arrangement (though I just  
use a folding sawhorse and lift with my legs straddling the piano  
leg). We're talking less than five minutes a leg, not a real big deal  
in terms of time.
	I can't imagine replacement of a truck being needed to eliminate a  
buzz. I would shoot some viscous oil wherever there was contact (use  
some kind of oiler with extender tube), maybe linseed thinned a bit,  
as an alternative to PVC-E, either as insurance or if you are actually  
hearing a buzz from those other contact points.
