I am ordering the PC 7424 from Coastal Tool and the accessory kit from CMA. I noticed that the PC from Coastal tool is listed as coming with a counter weight which supports a 5" backing pad. However the CMA kit is a 6" backing pad. Is it necessary to switch the counterweight to prevent vibration?? Or is the 6" kit from CMA light enough to countinue with the 5" counterweight?
This is what it says on the Coastal Tool site about the counter weights:
"The counterweight is a half-moon shaped piece of metal attached to the shaft of the tool. This smooths out the random orbit action by providing a counter balance to the elliptical orbit of the rotating backing pad. If you change the pad size you must also change the counterweight or suffer unnecessary vibration and possible damage to the tool.
There are two different counter-weights which are clearly marked to indicate use with either the 5" or 6" backing pad. Therefore if you decide to outfit the 7335 5" Sander with a 6" backing pad for sanding or polishing you must switch to the counterweight for 6" backing pads. The same goes for the 7336 6" Sander. If you decide to outfit it for 5" sanding or polishing you must switch to the counterweight for 5" backing pads
The only exception is when using the 54745 6" Foam Polishing Pad. Due to its light weight and the small-diameter backing pad used (included with pad), it can be used with either the 5" pad or 6" pad counterweight. Porter-Cable outfits the 7424 6" Polisher with the 5" pad counterweight."
I didn't realize this would be so complex!!
