6.5" pads on a Rotary?

It seems that most of the dealers recommend 7/7.5 inch pads on Rotary polishers.

Is there any problems/conditions to be aware of if you use 6.5 inch pads on a Rotary (with 5" backing plate on Rotary).

Reason: I have lots of 6.5 " LC CCS pads I purchased for the PC. Is the 5 inch backing plate correct for these pads on a Rotary?



If there is a problem or whatever please explain so I know what you are talking about.

Thank you, Changeling
 
you will have no problems using them on a rotary..I use 6.5 all the time..in fact I just ordered the 5.25 CCS pads from danase for the PC and plan to use them on the rotary also...



you have better control with the 6.5 pads..less buffer hop..easy to manuver ...



your all set..no problems

Very cool, thanks Al, I read loud and clear. Mind if I ask what Rotary you are using?

I use a Hitachi and a Makita...the Makita is out of service now..waiting for a part...If I had to do it again I would do a Metabo..I used my buddies and its nice..very ergonomic fitting...seems lighter and just seems to go with the flow as you use it ..if you know what I mean...it is a quality machine...quiet also..

Yes you can use the egde 2k 6" pads with a rotary..just need the rotary adapter...and your set to go...I find the 6" pads work so nice ...no fighting the rotary...they just flow...easy to keep flat..less hop...



Hope this Helps

I'm going to be buying a Metabo within the next few months. It would sure be nice to be able to use my 6" Edge pads with the rotary. No need to buy another set.
 
I don't know does smaller pad on rotary end up more aggressive like it does on PC (I guess I will know soon) so watch out for that. At the same time I hear CCS pads are running cooler than others of same size so keep that in mind too if you end up using them.
 
We just recently tried this technique as well and have found what most everyone else is saying. In fact, we decided that we probably will quit buying the larger pads altogether and use only the smaller pads for both the rotory and our PC's.



The only thing I can think of is that you may want to reduce your RPM a bit until you get comfortable with the smaller pad. Then you can probably kick it right back up to where you were with the larger ones. (The edge of the smaller pad will spin faster thus potentially creating more heat)



Other than that, you should be fine.

Actually, the larger pads will spin faster, well seemingly. Sine the larger pads have a larger circumference, they have to travel further to make a complete circle. thus a 6" pad and a 8" pad at 1000RPM, the larger pad will spin faster. Is it enough difference to notice? IDK

that seems strange, wouldnt the smaller pad make a revolution quicker than a larger pad, more rpms? can someone witha degree in physics clarify?
 
this is from another forum.



"The speed at the outer edge of the pad will always be greater than the speeds inside when the pad is spinning. Simply put, the outside edge travels a farther distance in the same amount of time as the inside, which means its moving at a faster speed. Make sense?"



"Makes perfect sense. If you placed a mark on the outter edge of a 8" pad and then one at a 6" point, they would be back at the same spot at the same time. The outter HAD to move faster to get back around at the same time.



Remember a DA is oscialating. A smaller pad on a DA will move faster giving more cut."
 
Let me add this, Aaron from Edge pads is the one who helped clarify everything on this other forum. Neither of the quotes above were his quotes, just customers relaying what he basically said. Hope that and everything makes since.

Al what is your feelings on the Hitachi vs the Makita? I still plan on getting the Metabo.



Since you are used to the Makita and Hitachi, when you used the Metabo was there anything you "Didn't like", are particularly care for?



I thoroughly understand everything else you explained.



Thanks, Changeling

Forgot a question Al. When you are using the 6.5 inch pads are you using a 5 or 6 inch backing plate ?

I use a 5" plate...I like that security of some extra foam on the edge so I can get close to mirrors and handles and not worry about the plate hitting it so easy.....that way the plate does not hit it by accident...







I liked every thing about the Matabo...seen no faults with it...ran like a swiss watch...



I like the Hitachi it runs nice...I like it a bit better than the Makita..seems a bit lighter..but all in all there is not much difference in the both except price and warranty...Hitachi has 5 years and makita 1...but I never had a problem with the makita till I dropped it off the roof and cracked the housing....I use it as a sander also...both great tools....



I got my Hatachi when they were $99.00 so it was a steal...

Thank you for the clarification. I got it backwards. I stand corrected.
