Cary, and everyone out there in Orchid Land,
"DO NOT USE OIL ON YOUR FLEX SHAFT"
Oil will only run down your flex shaft and into your handpiece.
You should use a "High-Temp" type grease which will not run down the
shaft, but will stay on the shaft and silencer spring where it
Or better yet, try contacting the motor manufacturer, Foredom,
Pfingst etc. and ask them what you should use.
Just thought you may want to know.......
Sincerely, Richard Lucas
