I got mine from toolsplus.com for $119.00. That is the best I've seen. Do a google search.

Adam's had them for $109. That's the cheapest I've ever seen them. I can't find them for that price on the site right now. You snooze, you loose!

Bonus! Nicely done!

OK so I'm a little confused and wanted to get clarification before starting if possible. Asked PC via e-mail what the difference was between the PC 7346SP and 7424XP and answer was:
"This is the same unit, however the 7424XP comes with a polishing pad only. The 7346SP includes both a sanding pad and polishing pad. The 7346sp also includes a heavier duty counterweight which will accommodate the sanding pad."
So my confusion boils down to pad size, counterweight size, and some info. in Junkman's videos. The adhesive backing plate that came with the PC 7346SP is a 6" pad and it is the exact same size as the Backing plate I purchased with the Orange, White, and Black Adam's pads (actually measured the backing plates are 5 7/8"). The counterweight on the PC is a 6" counterweight. Is this the counterweight I need to be using or do I need to get the 5" counterweight? Junkman's video says use the 5" weight with 5" pads and 6" weight with 6" pads. Did Adam's pad size change because they seem to fit the 6" backing plate perfect?

We're gunna need AJ to chime in here. He's the PC expert.

I've posted this answer 3 times in two days!

Here's the deal with the polisher. The main difference between the PC-7424 and the PC-7424XP is the XP is a more ergonomically designed unit that has 800 more oscillations per minute (OPM's) of power.

Now let's talk reality. Will you notice the difference in power? Absolutely NOT. As far as I am concerned (and I have both), they are exactly the same. You will think the same thing if you spend a week using each side by side, all day long at a car show. That's how I came to my opinion. The other models of the PC come with different backing plates or that useless pad. If you bought the Adam's pad kit, then you have everything you need. Just remove whatever backing plate is on the unit, toss that white pad gettup in the garbage and put the Adam's setup on your PC. Bam, you're done.

Now for the counter-weight subject.

Just to clear up any confusion, everyone should understand the purpose of the counter weights. Their purpose is exactly why they are named as such. The technical definition is, "a force or influence equally counteracting another."

The force that the counterweight is counter-reacting is the combined weight of the backing plate and pad. That weight is also influenced by the speed of oscillation and the weight of the moisture on the pad. If you where to weigh the Adam's backing plate and pad, you will find out that both are similar in total weight to the 5" counterweight. Even as your pad begins to fill up with product, the combination is still compatible as long as you work the polisher at the correct speed and do not saturate the pad with product. It is when you get the combination of incorrect oscillations (as in too fast in the operation), combined with too much product on the pad (as in saturated), that you throw the "balance of nature" out of whack when it comes to the PC and the Adam's equipment in question here.

If you operate the polisher at the correct speeds using Adam's pads and backing plate, coupled with the correct amount of product, you will see no difference between the 5" or 6" counterweights. It is when you drastically alter this combination that the vibration truly becomes evident. There are however, various backing plates for the PC-7424 that will require specific counterweights as they are heavier. Here are two such backing plates that I have that call for the 6" counterweight.

At the same time, I also have one that is similar to the Adam's backing plate that calls for the 5" counterweight. The difference here is, this backing plate is made for using the PC as a sander, not a polishing tool. This combination of course is a much lighter setup that a polishing setup would be.

For those who have watch my videos, you know that I do not like to work faster than a speed of 5, with 9-14 pounds of pressure. You can work at a higher speed as Adam does, however, Adam has been doing this for quite a few years and has that technique down to an art form. It takes practice, just as it takes practice to masterfully drive a car in a sport such as drifting. Cars are not meant to be driven to that extreme but in the right hands, it is an art of feel and technique.

All of this is to say that with a proper technique, do not get caught up in the counterweight that you use unless you are working with different accessories that are available for the PC. The 4" focal pads on a speed of 5 with either the 5" or 6" counterweight should present you with no issues. However, if you crank the PC up to 6 with those pads, the PC can become another animal. You will sacrifice control and probably not achieve the desired results that you are looking for. The key again is technique. Take your time and work methodically. If you begin to tire, stop and take a break or call it the day. I often take multiple days to work on an issue. The results will come and like fine wine, you don't want to rush it.

Last question from an OCD machine polishing/waxing noob, is it safe to use my PC 7346SP with a 6" counterweight along with the Adam's backing plate and 7.5" pads? I do not need the 5" counterweight and I can't damage my paint with this set-up, correct (your "How safe is the PC video" is ultimately what caused me to decide I can machine polish/wax my own vehicles)?

You will have absolutely, positively no problems with that setup. If you do, I'll buy that PC off your hands for exactly what you paid for it. There's putting my money where my mouth is and doing it in print large enough to see, period.

It bores the crap out of me and I have found that it puts most people to sleep. That's why I avoid a bunch of it in my videos. When I hear professional detailers start into one of these tirades, I usually glass over and start thinking about doughnuts.

Hopefully Dylan will avoid that at the Stillen clinic coming up.

Thanks for taking the time to answer all my questions. It is much appreciated. I just wanted to make sure that I didn't make a careless mistake (like not putting the washer on the PC) that would lead to an expensive repair bill. Junkman, you are definitely the man.
