Hi guys! I've had a problem with my orange cutting pad... For some reason whenever I start buffing (usually on speed 5-6) the pad likes to stop whenever I apply VERY little downward force. I find this extremely irritating. Any suggestions?
 
actually, you need to apply some force to get the pad rotating but it will stop if the pressure is uneven. What makes it safe also makes it kind of annoying...

is your bp marked? what kind of machine are you using? first gen PC?
 
How much experience do you have with the DA?

Are you making sure you are putting even pressure on the pad and not favoring one side of the pad or the top or bottom?

Does this happen with a softer pad like a black or blue pad?

If you can pull out a scale and try and measure how much downward force you are applying for us.

I have the latest PC 7424XP. I barely apply any force and it just stops. And I never have any problems with soft pads for some reason.
 
And yes the backing plate is marked.
 
i had an issue like this with one of my yellow pads. couldnt figure it out then i noticed. the glue on the back of the pad that holds Velcro must of failed the backing of the pad was only being held on by a small area on the outer edge of the pad and the pad wouldnt spin due to it. it would if i bared down extremly hard but eh pads wear out specially if u let someone use it that has no clue what there doing and ur not around to teach em. and they let the pad get so hot it made the glue fail lol (for the record it was on there own car and they said they've used it before a friend of mine lol can u say BUSTED lolol)

That's correct.

If you just let the tool kind of flutter on the surface the pad will actually stop and sometime rotate backwards or go backwards and then forwards and then backwards and forwards etc...


Now take and press down on the head of the tool and it will start rotating the pad in a clockwise motion. (Assuming you're on the 5.0 to 6.0 speed setting)


It's a strange phenomena...

Try pushing down hard but not so hard the pad won't rotate. You need to make sure you're holding the pad flat to the surface all the time.

Also, see this article,

and everyone else for the feedback!
 
Also the size of the pad has an effect to, are you using 6.5" or 5.5" pads?
 
It is just my opinion, but when I use a random orbital polisher, the jiggling motion gets most of the work done, and the pad doesn't necassarily have to rotate.

If that works for you then that's all that's important.


As for me I want to see the pad rotating and thus pushing or moving the abrasives over and against the paint, not just jiggling against it. If I'm using a DA to remove swirls that means I'm using a DA to remove paint and again, jut my opinion but abrasives being moved against, (that's downward pressure), and over, (that's rotating, not jiggling), the paint is going to remove a little paint faster and more effectively.


Kind of like if i take my hand and work and abrasive product over the paint I move my hand over the paint with pressure, I'm not sure how far I would get to put the applicator pad on the paint and then jiggle or vibrate it.

Actually, when people join forums and ask if they can use their wood sander in place of a Porter Cable 7424 I always tell them it won't work because while it's the same type of tool as a PC in that they are for sanding wood, most all DA Wood Sanders except the PC just vibrate the pad because they don't have the power or ability to make the pad rotate.

Some then try and use their wood sanders to remove swirls but if memory serves me correctly, in every thread on the subject the person with the wood sander ends up giving up on their wood sander and buys a PC style polisher.

One more thing just came to mind, the first DA Polisher Griot's introduced was a wood sander and the number one complaint everyone had about it was that it would not remove swirls and the problem was that it couldn't rotate a pad under pressure... just jiggle it...

Point 100% well taken.

I was hesitant about even posting that, given your recommendations about rotation, and drawing a line on the pad etc., but I guess @ the end of the day, whatever gets the job done!.

You work on far more cars than I do, so I would definitely recommend anyone reading this thread follow your directions!

I've seen one other guy "allude" to the idea that the pad doesn't need to rotate or that it isn't important but that's as far as he goes.

Big picture... if you can find a way to reach your goal that's all that matters...
