K7NV has a web site and builds PP motors for the owners or for resale, his  
site has a lot of info on how to take these PP motors apart, rebuild them 
or  lube them for service. Hope this helps-

What is  the maximum DC voltage used successfully/recommended for one of 
the  "small"  PPM's ?  What speed was accomplished and how was the brush  life 
at that voltage ?
I 'm building a power supply to put at the base of  the tower and can 
change the voltage from about 30 to 48 volts in 6 volt  steps. Cable to PPM 
be 100 feet of 3-#12's. I'm figuring about 0.5 ohms  and about a ten amp 
demand  i.e. a 5 volt drop.
Any suggestions will  be greatly appreciated.
