Can the PC be modified tormove safety?

[carsfeverguy]

I understand that when pressing too hard the PC stops turning to prevent damage...

I would like to know if there would be a way to make it keep on spinning even when increasing pressure.

Basically removing the idiot proof feature the PC is so famous for.

It is not a safety it's the way it's built. If you're looking for something more powerful and/or aggressive take a look at the flex 3401 or a traditional rotary buffer.

It's a lack of power issue not a safety issue. My GG DA with a 5" backing plate and 5.5" pads is almost impossible to stop with any amount of pressure at speed 5. If you used a 5" backing plate with THIN pads it might help-- like the new Megs 5" thin pads.

Yeah, you should be buying a rotary or FLEX then not trying to use a machine for something it is not.

Thank you for your opinion.

Plenty of tools are modified to suit ones needs.

The PC stopps spinning when it considers too much pressure is applied. Where in the system does this variable come from. And where can it be adjusted from?

If you don't know that is ok, but no need to advise buying x y product.

What they are saying is that there is no "safety" that can be turned off or adjusted. If you disassemble the unit you will observe that there is no clutch or gears driving the pad rotation that can be modified. If you Google dual action polisher modifications, you will get an idea of what can be done. What is it that you are attempting to achieve?

You'll need to find a way to overcome

"Free Floating Spindle Bearing Assembly"

"What is the mechanism called that causes the polisher to stop rotation when excessive pressure is exerted upon it?

Some of us are having a discussion on an online auto detailing forum and I incorrectly referred to the mechanism as a 'clutch' (such as my drill has). I'd like to clarify this for the sake of accuracy.

Thanks."

[Porter-Cable's reply]:
Dear James, we believe the following information addresses your inquiry. The pad itself may stop rotating temporarily with excessive pressure, because it is mounted into a free-floating Spindle Bearing Assembly. However the overall mechanism is fixed & therefore never stops orbiting when the machine is running, unless something is damaged or worn.[End reply]

"So there you have it. I guess our 'mechanism' is called a "free-floating Spindle Bearing Assembly"[unquote]

I had read that before, but thank you for posting it here.
I found the schematics of the porter cable...

I guess one would have to take it apart to find out.
It's not magical...

the answer has already been provided.

the essence of the machine's effectiveness necessitates the free spinning aspect. it's not a safety feature, it's a part of the function. it just so happens that it's safe because of this function...and lack of power.

considering that, and what was said about the GG6, which is true, then you have your answer - do not try to remove the free spinning part, but simply increase the power of the motor in a major way so it mirrors the output of the GG6. however, doing so might compromise the rest of the system as it was likely not designed to handle power that it otherwise would never, ever see. this includes gearing, fasteners, cooling/breathing, power wire gauge, terminal/contact size, etc.
