Rupes 15 dial knob question

**tpr1634** · 06-29-2015, 07:54 PM

For you guys who have the 15, there is no speed difference from 5 to 6. The dial knob does feel vague how are your polishers is there no difference, this was my test run with my 15 or is there an issue ?

I have one and I just got a GG21 and I have the same thing on it. I don't notice a power change on either between 5 and 6.

The GG21 dial is definitely an improvement over the Rupes and so is the cord.

Seems odd, I know on my PC as crappy there are compare to the Rupes at least when you go from 5 to 6 there was more mustard.

As per my post here: http://www.autogeekonline.net/forum/...es-2015-a.html

After reading this I quickly went and checked each speed on mine, there is certainly an audible difference and an rpm change for the greater going from speed 5-6. Its not as pronounced as going from 1-2 or 2-3 or 4-5 but its certainly evident enough.
