New PC- my hands are going to fall off...

I'm with the "must get used to it" camp. Even though I've used it on a lot of cars, it still bothers me a little. I'd much rather use my Makita though.
 
Hi everyone.!

This is my first time on this site

I would like to tell what I really like this project "index.php"

I've been reading it for a while, and I have learned so much here

So, I decided to try my luck asking a few questions...

How can you IM, PM or whatever you call it to certain members?

I'd like to ask more questions about this project.

By the way, nice domain name autopia.org
 
yeah, i dropped mine once and thought i knocked off my counter balance. but it never was smooth. the pc on 6 has to be the most miserable at long time use. my brother has a griots orbital and it is a dream, you can barely tell it is turned on.
 
The vibration just takes a little getting used to. Using it on speed 5 will lessen the vibration but for polishing purpoes 6 is the way to go. After a couple rounds w/ it you won't even notice it.
 
I'm a office computer type guy and my initial experience with the 7336 using PC polishing pads on 6 was terrible. I could barely control it. Like you, I ended up with numb fingers and had to take a break every panel or so.



I ordered a flexible 5 inch backing plate, some LC pads and ditched the handle. Went through a run with SFX-1 with orange pad, FPII with white, and AIO with white non stop on the entire car. HUGE difference with the lighter backing plate and pad and no handle.

I've read reviews of Griot's orbital where reviewer was saying it wasn't as strong as PC. There might be a correlation between that and "smoothness".
 
I certainly am no expert, I haven't even turned on my new PC yet!!



But, while researching the product i was told to get the LC 5" backing plate to use with 6 1/2 inch LC pads.



I was also told that you use the the rotor weight associated with the size of the backing plate, "not" the size of the pad.

In other words, 5" Backing Plate, use the #5 weight , 6" backing plate use the #6 weight. These weights are marked right on the counter weight.



Don't get confused by the terms Backing plate vs Backing pad. The Backing plate screws onto the Porter Cable , the backing pads have a Velcro backing and stick onto the backing plate.

Also, the PC with a 5" backing plate and a #5 weight used in conjunction with pads up to 6 1/2 inches is considered "ideal" for this tool.

No one explained this completely, so I am giving you the information I have gathered in putting together my PC and pads. Check all these things to see if they are correct before you jump to conclusions. If you still feel that something is not right, go down to a local body shop and ask one of the guys to take look at it and see if he thinks it is operating correctly.

Certainly hopes this helps you.

I take a different approach:



Remember that the PC was really designed for use as a sander. The counterweights were designed to match up to the backing plate *with a single sheet of sandpaper stuck to it*. That sheet of paper weighs a *LOT* less than a foam pad (let alone a foam pad soaked with product). So I use the largest counterweight (the one for 6" plates/pads) with *every* size backing plate and pad, even the little 4" ones I like so much.



I've been using the larger weights with all my plates/pads for a long, long time now, with no problems at all. *IMO* the larger counterweight cuts down on vibration with no adverse effects on the PC. I haven't used my 5" counterweight for years.



But then others swear they can't tell any difference between any of the counterweight/plate/pad combos so :nixweiss

Thank Heaven you came in on this, it appears, IS, a situation where I listened to the wrong expertise, this makes me a "Parrot", and I will try to not give advise that I have not tested ! I did mention that I had no experience with the PC, but was using information NOT gained from experience!! Weak excuse, I know, I apologize to all.

I think I damaged a tendon in my right hand/fore-arm (keep the jokes to yourself) on my first PC use. Seriously. Swelled up like a golf ball!
