I just read Mike's recent review of the new Rupes bigfoot LHR 19E rotary and I was impressed with the machine.

Problem is I previously decided on the Flex PE14-2, but fortunately have not bought it yet.

Directly comparing the two I can't see significant differences between them except for the RPM ranges - 450-1700 for Rupes and 600-2100 for the Flex. Since I haven't used any rotary yet I'm wondering if the Rupes represents an "overshoot", so to speak, in exploiting the trend for lower rpms in new rotary models for car paint polishing. I say this because I've seen it before in other product markets - some manufacturer takes a trend too far and ends up with a black sheep product before industry realizes it took a concept to far then abandons the stupid feature/product and returns to making a proper product.

In Mike's review though he supports the ultra-low 450 rpm feature. Unfortunately this has put this question in my mind about which range of rpms is better after taking all into consideration. So it looks to me like the two models are otherwise practically identical, complicating the buy decision. If I could fondle or try running each model I belive the decision might be easy but since I can't do that I just gotta pick one.

The way my brain works I don't like choosing between identically good products. On the other hand I like Flex products based on my 3401 forced DA, the quality is outstanding. But the quality and design of the Rupes appears to be identically outstanding. I also prefer to avoid first release products of any kind, but given Rupes' reputation the Rupes might be a reasonable risk purchase. Unfortunately all this makes me a little crazy because I like to have clear winners for decisions. The last thing you want is going crazy detailing someone's car. Ha !

How might you guys approach this decision if you were in my shoes ? And though it's probably a long shot, if anyone owns both or has used both I'd sure like to hear your thoughts.

If Mike was forced to make the choice himself he may not be able to write about it because they're both great machines and Autogeek sells both.

Maybe this is a case of it doesn't really matter - just flip a coin. I don't like to flip a coin when dropping a whole lot of coins.

Or maybe it's a brand-loyal decision versus a best of breed decision.

I'm not committed to either philosophy because I practice both buying philosophies myself in other areas.

Any thoughts much appreaciated. And if it helps any I'm an "experienced newbie". I haven't heard that classification yet but I think that's where I'm "at" more or less.

Here is a review I did on the Rupes

Rupes LH19E Rotary review


I have both the Flex and the Rupes rotaries. Both are awesome machines and you certainly can’t go wrong with either.

The 450 Rpm range is certainly legit.

I hate the Long cord on the Rupes and that’s my only issue with it. It can be cut and shortened.....ask me how I know. Lol. The trigger on the Rupes is amazing and gives you infinite control.

It would be tough to make a decision but personally I would choose the Rupes for automotive. Perhaps if I was doing automotive with occasional boat or RV buffing I would choose the Flex.

Check the specs out on both. Maybe one has an option or options you like better. Both are indeed great tools and you will NOT regret either choice.

Here's the deal, I just obtained the RUPES RP a couple of weeks ago, right before we buffed out an aluminum Grumman Van.

So I have not put hundreds of hours behind the machine yet to be able to make a valid comparison. I HAVE put hundreds, if not thousands of hours behind the FLEX PE14 so I do have a VERY valid opinion of it. I've been using it since it was introduced, in fact FLEX gave me the #2 production unit which is about 4 feet away from me on a shelf with all my other low production tools or beta tools.


Boat Detailing
Tell you what... the really hard buffing for a rotary is when you're buffing out neglected boats, both removing sanding marks or just removing oxidation and I've done a lot of both with the FLEX PE 14 and it can take it.

So if the RUPES can take that kind of torture then it's a contender. If it can't then I'll have to give the edge to the FLEX PE14 but only time will tell, which means I have some hours to invest into the RUPES RP.

Hi Mike, I look forward to hear more about the 19E as you're able work more hours with it. Dr Oldz, that is great information, after reading your take on the Rupes I like it better than before. I have noticed a significant difference between them but I don't know enough to make a judgement, and that is the difference in gearing design between them. I don't know much about gearing technology so I haven't a clue regarding any tradeoffs between the two designs. But my guess would be that the Flex might be stronger such as in Mike's boat jobs, with the ring gear. A worm gear running on top of a ring gear seems like a good situation for handling torque, but I don't really know. If any of you guys have knowlege about gearing design that could be significant.
 
any reason the L3403 doesn't get as much love as the PE14 or seemingly even the Rupes? Looks like a nice lightweight alternative.

I think it was mentioned above but the lowest RPM option is 1100 RPM

Could just be personal preference, but I usually buff from 400RPM to 1100RPM so I prefer the PE14 and now the RUPES rotary polisher.

If I go with the Rupes rotary at 600 rpm at low, vs 450 rpm at low for the pe14, will I miss that 150 rpm slower speed difference or wish I had that low range available ?

Can you use a shallow trigger press on the Rupes at the lowest setting to get down to 400 rpm ?

You have them reversed:

Rupes=450RPM
Flex=600RPM
 
I'm looking for a rotary to polish around emblems and small tight spots only. Which one would be better for this situation?

I have the Griots G3 with 1 &2 in backing plates and extensions, but I'm scared I will still do some damage with the oscillation.

I personally prefer Flex 14-2 my other rotary is the Dewalt (Bumblebee) which is old school heavy workhorse. Rupes makes a great polisher as well although I have yet used the new 19E.

I doubt most people can tell the difference in 150 rpms in rotation. There are many ways to control the cut other than just rpms.

Keep in mind one of the best combos on a rotary is wool and foam/wool hybrid pads, just amazing vs the DA methodology. Many fear the rotary the 14-2 is so perfectly balanced you can run it with one hand and is much lighter than most other rotary polishers.

IMO every Detailer should have a rotary in their arsenal. Just keep in mind you’ll need some different pads and compounds/polishes to really make the package complete.
 
Would the Rupes and Flex be a good tool for 1 and 2 inch pads as well? Should I keep it at its lowest speed with those smaller pads?

I would like to learn to use a rotary so I would prefer to get one that can handle al pad size and still be safe enough for a newbie to use.

Get the Flex 14-2, Buy Once Cry Once. That polisher can do it all. The quality today means it really come down to personal preference.
 
For me, the ability to spin the pad faster has more value than I'd think I'd see on the low end. I did own the PE14-2 and it sure was a sweet polisher for it's light weight and ergonomics. I sold it to get something more HD and recall regretting it a time or 2. I honestly don't think you'll top the build quality of the Flex branded tools. I wasn't impressed with any of the Rupes machines I've tried, considering the price.

They were nice machines, just not worth the money IMO.

Sorry I missed your question about smalle pads. Yes I run smaller 1, 2 & 3” pads on my Flex 14-2. Now I run dedicated 3” pads on my PC (Porter Cable and leave the 1 & 2 inch pads for the Flex 14-2 when I’m doing small detail work. Remember any time you start running smaller pads due to their size the are more efficient (aggressive). Definitely run them at slower speeds. You should also put an extension on the buffer for more clearance.

From my perspective I prefer forced rotation but I grew up with the Dewalt and large wool pads. Several decades ago Da’s were new machines and the rotary was the be all end all. Now we have light weight rotary buffers and 5.5” pads with hybrid and new technology wool pads. LOL its not your father rotary buffer!

I also use Fles 34-01 DA forced rotation. I try to keep machines, pads and polishing products simple. I wind up using a rotary (my preferred tool) 80% of the time. I keep the other buffers configuresd with smaller pads so I don’t have to stop and reconfigure buffers when I get to the smaller areas.

Hope that helps you.

Thank you for response! I think I'll pull the trigger on the 14-2!

I think you'll be very happy! My PE-14 sees pads ranging from 2" all the way up to 8" (on rare occasions), and hasn't missed a beat in the 3 years I've owned it!

I'm sure the Rupes polisher is fantastic too, but I'm leary of the forward grip on it becoming uncomfortable over time. When I owned the Mille, in order to put enough downward pressure on the pad, I would be using primarily my thumb, which fatigued my hands way sooner than my 3401. On a long throw, its is less of an issue because you tend to use less downward pressure.

With the large head grip on the PE-14, you are able to center the "Pad" of your hand on the forward grip which makes putting downward pressure that much easier. Also, the center of gravity (referring to distance between the front grip of the tool to the polishing surface) is less on the PE-14. Again, using my Mille as an example, it felt more "tippy" than my 3401. I imagine this also translates to the rotaries.

If you use a side handle, then these are moot points, and it looks like Rupes has a far superior side, and bale handle design.

Overall, both are great! Let us know how you like the PE-14!
 
Min rpm with the Rupes rotary 19E is 450 while min rpm for the Flex PE14 is 600, ok got that. But is the difference in minimum rpm between these two machines (150 rpm) significant enough to warrant getting the Rupes over the Flex, assuming that other variables are equal (whether they are or not, just want to consider the 150 lower rpm difference alone). I want to know what you guys think about that extra lower 150 rpm capability means to you, particularly for small sections of damage on car paint, not working on boat hulls etc. Will the extra low 450 rpm give me additional benefits over a 600 low rpm in those scenarios ? Also will 450 rpm give me advantages in jewling over 600 min possible rpm ? I have not used a rotary nor have I jeweled, but I'm going to give it a shot after I can answer this question about the 150 lower rpm capability between the two machines. Also some driver installed a 4 ft paint transfer/scratches/dig to the metal combination of damage to the rear box panel on my F150. So I would like to start my rotary experience in working on those different types of damage very lightly, slowly, and delicately with one or the other of these two machines. I know I could do it by hand very safely, but that's not really my question. Any advice about that 150 lower rpm would be greatly appreciated.
 
To me yes the lower RPMs matter. For you learning on 450 is better than 600. When buffing edges or high spots, I like to take it easy so being able to keep the triggerlock on and work at 450 is valuable to me. The Flex will go lower than 600 if you throttle the trigger but the trigger isn’t as precise or comfortable as the Rupes. Jeweling I do like to do at the 450 RPM range if the paint reacts to it well. Sometimes I will bump it up to 600 or maybe 750 but having the option to go to 450 is great.

Just so you are aware the 450/600 speeds are on the trigger lock. Both machines go slower but I like to work with the trigger lock ON As much as possible so I con concentrate on what I am doing. Make sense??

To add: the lower RPM doesn’t matter to me when using smaller 2 or 3 inch pads as you will want higher RPMs for those but when getting to 5 inch or bigger pads it matters to me personally!
