Bshappered, your VPI has a synchronous motor I beleive. That means it should sync up with the 60 cycles from an outlet. The 60 cycles is almost always accurate. The voltage will vary a lot in some places, but not the 60 cycles. You could check the outlet voltage with a multimeter. Read the instructions, and be careful. You could also get a P3 Kilowatt meter that just plugs in. Your voltage could be from 114 volts to 126 volts. With that voltage variation, the VPI should hold its speed. Something else must be going on, unless you really have voltage out of the 114-126 volt range. The 60 cycles will keep it right with 114-126 volts. A link for a P3 Kilowatt, that might be sold at your local home center. [http://www.mcmelectronics.com/product/28-10985&CAWELAID=220321019]
VPI Scout - slow speed , help ?
Hi
I've recently purchased a KAB speed strobe which has indicated that my Scout is running very slow (notches moving counter clockwise); over 100 notches in 60 seconds.
I have the newer black belt with unknown time on it; I've cleaned the belt, motor grooves and platter grooves. I get power from a dedicated 15amp plug, through an Audience AR-6 conditioner and stock power cord to the motor. I've tried using different notches on the upgraded 300 rpm motor pulley, with little effect.
I suppose the cheapest experiment is to buy a new belt, and lube the spindle bearing (for which I'll have to purchase oil) and see if that changes things. Short of buying the VPI SDS, are there any other actions which may help here for little money? Perhaps a used Variac would essentially do what the SDS does?
Your constructive feedback is appreciated.
Regards,
Bryn
