Buyers remorse

whiteWRX · 05-11-07, 06:49

Hi,
So in my adventures to the world of rotary use, I just purchased the Edge 2k 8" wave pads. Just have to say these are HUGE. Now I am a little concerned that they may be a little too hard to maneuver around. Just wondering if I would be better off getting some 6" pads instead. So my questions are:

1) Are these the 'safest' bet for a beginner (ie least amount of heat build up)

2) If and when I get some 6" pads, should I go flat or wave style (again safety/ease of use are my primary concern)

Thanks

from what I have read 6" is safer than 8"

I have the wave style and like them tho i have not used anyhting else

Is the white or blue better with PO106FF?

white is a much softer pad but i finish with a PC

try sending them back to the vendor and getting the 6 inchers or contact Aaron directly.

It's all all in what you learn on, I have used 6.5" and 8" wool pads, I prefer the 8". It's like when I did lawn care - there are two basic methods of controling a commercial walk-behind mower - Toro's T-bar and Scag's grip levers, most folks get brand loyal quick but the guys that run Scags - NEVER arm wrestle them unless you're Popeye! To me, it's easier to run a buffer with the 8", wider base made it steadier.

I always trained people with an 8 incher without any problems. Start on the large flat areas to get the feel of things before moving into the curves and edges. You'll be fine. Just work slow and stay loose.

The people never mention about bigger pads is they make the rotary act more aggressive. At 1000 rpm, the outter edge of a 6 inch pad is traveling 18.84 inchs per rotation or 1884 inches a minute. That is how fast the pad is abrading against the surface at the outer limit.

A 8 inch pad @ 1000 rpm is traving 25.12 inches per rotation or 2512 inchs a minute. To achieve this level of working power in 6 inch pad you would have to spin it at roughly 1320 rpms.

What produces more heat, and 8 inch pad @ 1000 rpm or 6 inch pad @ 1320 rpm? They should be about equal (setting all variables equal) so the question becomes which pad with disipate the heat better? An 8 inch pad is producing its working power over a greater area, so the in this case, the 8 inch pad @ 1000 rpm is producing the same working power as the 6 inch pad @ 1320 rpm and removing heat from the surface faster.

People are correct in assuming that at equal RPM's, the 6 inch in pad produces less heat. It also is doing less work. To be equal you have to spin the 6 inch pad roughly 30 percent faster.

So see what you llike, try the 8 inch pads (I don't like them as I feel they steer me too much). See what you feel the best with, but remember that 8 inch pads cover more area, do more work at lower, so if speed is a concern.....

I've never really thought buffing was this critical of a science for people. That pretty analitical.

Wow

Thanks for the great replies! I think I will hang on to my 8" blue pad (from what I read its all I really need).
I'm attempting to contact AG to see if I can trade my other 8" for some 6".
For the 6" should I go wave or non-wave. It almost seems like the non-wave might distribute the polish better. Any thoughts?
Also, would the white or blue be best for PO106FF?

Thanx again.

Heh heh, I really like explanations such as that post from TH0001. IMO it's not like people overly apply the ol' brain cells to this stuff (or much of anything else) and good, logical thinking is, well, good

On-topic, I found the 6.5" pads easy to use from the start. IMO a rotary-newbie might find the larger pads a bit harder to control, at least if DIYing the learning curve as opposed to having expert instruction. Havng somebody with experience there at the get-go would be *so* valuable!

Just my opinion, but I personally, like the smaller pads for a rotary. I find them a lot easier to control than the larger ones, and by doing a smaller area at a time you can concentrate a little bit more on the polisher vs. the pad.....make sense? In other words, I used a set of large pads when I first used my rotary, and it skipped and jumped all over the place. I had such a hard time trying to figure out how to keep the pad from going crazy that I wasn't even thinking about technique. Since then, I have stepped down to the very same 6" flat pads that I use on my PC and haven't had any problems.
