As the title states..what is the difference between the two? Would like to pick up a 7336 for Lowes cause they are on sale for $105, but want to make sure it's the same. TIA :xyxthumbs
 
Why do they (PC) outfit the 7424 6" Polisher with a 5" counterweight? I thought you were supposed to use the appropriate counterweight as per the size...
 
I think different combos of backing plates and pads cause different amounts of vibration through the PC. This is where the counterweights come into play - to counter-act the vibrations. Does that make sense?
 
I suppose they supply the 5" counterweight as standard because this works best with the plate/pad that Porter Cable supply as standard with the unit. The package from Coastal contains a 6" hook-and-loop backing plate.



You won't really know if you need the 6" counterweight until you start changing to different backing plates and pads. Always handy to have the two I reckon.
 
I've got a 7336 and it came with a real nice steel carrying case that holds the (never used) sanding attachments, vacuum suction, etc.
 
I don't understand why someone would purchase a 7424 when they can purchase a 7336 for cheaper? They are exactly the same machine. The defference is how they are set up, the 7336 comes with a 6 inch counter weight, the 7424 comes with a 5 inch weight. So if you buy the 7424 and replace the counter weight like you should with a 6 inch weight you now have a 7336 that you could have purchased in the first place for less money. It seems like there are a lot of people purchasing 7424 models and converting it to a 7336 model, why?



I asked for and received a 7336 for Christmas. It was $20 cheaper than the 7424 and it already had a 6 inch counter weight. The 7424 comes with a stock polishing pad but from what I hear it is not very good for paint. The $20 savings between the two models went to the purchase of a backing plate and some Megs pads. I can't see any benefit at all to purchasing a 7424 instead of a 7336.

The white pad that comes with the 7424 is light enough that the 5" weight is what matches it best. That pad is 6", but it doesn't have an actual backing plate with it that you can use. If you were to buy the sanding machines 7335 or 7336 they would come with 5" and 6" PSA backing plates respectively, and matching weights.



A lot of people still look for the 7424 because it's called a polisher, is marketed as such, and was the "original" PC model number that everyone referred to. The 7336 does make more sense to actually buy, but then you have to explain to them that it's actually a sander, etc etc etc...





Also check out the thread I have compiled, linked in my signature below. It's not very user-friendly, but it explains a lot.

Thanks for the info. So I will be fine with a 7336 with the kit from Detailers Paradise?. I called them and they said they would throw in the 5" counterweight in free for buying the polisher kit that comes witha 5" urethane backing plate. Then, the only difference will be that I have Model 7336 instead of 7424, but equally identical with the same counterweight, right?

Yes, the machines are identical except for the accessories and the counterweights. Honestly you probably will never really need to use that 5" weight unless you want to use the included white pad or want to do some sanding someday. ;)

EXCEPT when you consider the PC 7424 "Bonus Kit" from Coastal Tool. $119 US gets you the 6" velcro backing plate & 6" counter-weight already included. Granted the counter-weight is an inexpensive part by itself (typically $2-$4 US), but the 6" backing plate is usually $15 US or more depending where you shop.



Also you're saying a 7424 model + the 6" counterweight = a "7336 model". Correct me if I'm wrong but doesn't the 7336 come packaged with a sanding plate(s) instead of a polishing pad? Most people probably don't use the PC pad, but maybe some do? :nixweiss



And I've done local pricing surveys here in Alberta and I haven't found the 7336 to be consistently cheaper. They are usually within ~$10 CDN of each other but it flip-flops from store to store as to which is the higher priced, but it doesn't really matter because its expensive at all Canadian retailers. I found the Coastal Tool deal to be WAAAY better -- especially since they will ship to Canada via US Postal Service if you ask (so you don't have to worry about brokerage fees).
 
I second MacGirl's suggestion. My wife ordered my PC from there for our anniversary, and the service was outstanding. They even sent me a free gift as an anniversary present (which I've used and really like. When I'm out of this bottle, I'll order some more). I thought it was a very nice touch.

Back to the original thread, everyone seems to agree that the 2 machines are the same, just marketed different, I guess. I have the 7336 that came with the 6" counter-weight and 6" original PC pad. I've used that pad, 4" spot pads, and my Lake Country 7.5" pads. I don't feel any difference in vibration with different size pads (even taking the speed to 6). I don't know what a 5" counter-weight would feel like. I guess not knowing may be a good thing, because I'm very content with what I've got. I don't think the PC vibrates excessively with what I've got, but I only use it a few hours at a time.

I thought you had to use the 5" counterweight if you want to use a 5" backing plate, and same for 6"?:nixweiss



And being that I am going to order the 5" urethane backing plate, I assume I will need the 5" counterweight.
 
A few of us UK Autopians have the 7424 with the 5" counterweight and 5" flexi backing plate that's sold in the Autopia shop. We all use the 6.5" Megs pads as they're easily available over here in the UK. No-one has compained about that combo yet, everyone seems perfectly happy!



I got my PC from the Autopia shop, but I would of went for the Coastal deal if they'd have replied to my email with regards to shipping costs. But, I'm glad I did buy from Autopia - the service is excellent and very quick - I got my PC after just 6 working days (US to UK in 6 working days is very good!)
 
Inzane,



I don't know what price they are selling a PC for in your area but I purchased a 7336 here in Hamilton for $198.00 CDN. No shipping, no waiting, and no problem bringing it back if there was something wrong with it. The Coastal Tool package is a decent deal but work in the exchange rate plus shipping and it works out about the same.



Also you are right the 7336 does come with a sanding disk not a polishing pad like the 7424. There is a $20 difference in the models where I purchased it and I used that difference to purchase a new velcro backing plate. Also there is a 7336SP model that comes with the sanding disk and polishing pad and 6 inch counter weight. I think this is the model that was on sale at Lowes in the U.S. for under $100.00. That is the best deal I have seen on a PC.

Check out coastal tool's explanation of the differences between PC models at

I got the one from them for xmas. It comes with both the 5 and 6 inch weights. I think the 5" was installed. I use the 6" and do not have a vibration problem. I tried the 5" and noticed some vibration. It depends on the backer plate you use.
 
txz28,





I know the difference between the PC models.



You proved my point. You purchased a 7424 and removed the 5 inch counter weight and replaced it with a 6 inch counter weight, you now have a 7336.



Many people are buying 7424 models and replacing the counter weight with a 6 inch weight and now have what is basicly a 7336.
