4 inch pads

yes, just make sure to get the 3 1/2 backing plate to accommodate them..



also... if you're looking for a place to buy the backing plate (amongst others great items) patrick over at exceldetail.com has them, and i've been using mine for a while with no problems...

Dont know why people get confused about this.



What works on the PC will work on the UDM, they are the same machine, one is just on steroids.
 
I think the main reason is from the problem that the UDM currently has with the edge system.Until the new counter weight is available . I think i does have some issues with the 6 inch backing plates as well.But David can confirm this if I'm correct.But the smaller 5 inch and below should not have any issues that I'm aware of.

I agree with Coupe...I used the PC with the edge pads and I was not impressed....seems they bog the machine and the adapter gets hot ..seems the random orbit sorta grinds the balls down and they start to fall out....Edge on a rotary works good..but PC is another story..some have good luck with it..I did not....

The edge2k system is all i use on my rotary, will never go back to the traditional hook and loop system.
 
so will the reduced weight of the 3.5" backing plate work well on the udm? or will it be out of balance?

it will work fine...DavidB did a demo on scratch removal with a 4" pad and he said it was fine...

I have a UDM and used the 4-in pads with the smaller backing plate (2.75) without any vibration issues. I believe the counterweight issue is related to heavier pad/plate combo's so smaller (less weight) is better.

Woah! Consider a 3.5" BP for those pads, you'll find better results with less edge stress, equaling better pad durability....

I sue the 4" pad setup with the 3.5 BP, and have had great results. I would like to move up to a 5" pad, 4.5 BP though.

where?



I have the Sonus kit w/ SFX-1 and 4" yellow and bp. Felt soft to me and especially when pressure was applied(I'm new so?). Whats the best cutting setup for the UDM? believe it would be a 4" pad but which one?(thinking about CCS 4" yellow), and what compound?
 
I am planning on ordering a UDM very soon, but I can't decide just yet if I'm gonna go with the 6.5" pads or the 4" pads. What do you guys recommend, and why?
 
from what I hear you get some vibration w/ the larger 6.5" pads(thats why theres a new counter weight upgrade coming out). If you have to do correction the 4-5" pads are what you want. I just got a DAS kit and works good for polishing. I think 5" are good because you wont get much correction w/ a DA anyway.

I totally agree and completely understand why the move up to the five inch pads. With or without the wrong cw a four inch pad can be very hard to control and unpreditable regardless experience. Even for correction isssues the five inch pad is just as capable, and a lot more sturdy.



My father-in-law wanted a pc setup so i helped him order it and showed him how to use it, he thought he had nothing but four and five inch pads, when in reality he had five and six inch pads. We were a little confused how that happened but it worked out fine anyhow.



So I was using his five inch pads with his pc and love the differencial between the four and six/seven/eight/nine inch pad, it was a very smooth day polishing and I remember very little from the vibration issues.
 
So for a beginner like me it's probably best to start out with a 6.5" pad then. After I've gotten used to that, then I could move down to a 5" pad, and if I'm still not satisfied I could then try the 4".
 
I had struggled witht he 6.5 LC ccs pads with the udm. Alot of vibration and just seemed akward. I saw i had some a few lc orange 5.5 cutting pads lying around from some of my autogeek orders, Tried one of em, and wow, what a difference, correct faster, no obscene vibrations, and just all around worked better. Needless to say im trying to get rid of my 6.5s
