Rupes LHR 15 Legacy or Mark II

The 40% increase in power was been discussed here from 15 ES to 15 Mark II but I don't quite understand how it's possible if the motor is the same. The description on Autogeek says the power draw is the same but it "feels" more powerful. I don't doubt that it feels more powerful, but how much more powerful can it be with a very similar motor as the outgoing model?

Good question. I guess you can tweak percentages. Last I heard it was 30%, now its 40%!!

30% was the conservative average, the minimum value. Also the American or 110V version of the 15ES was 10% less powerful than the Euro 230V version and the 30% performance increase was over the more powerful 230V models so in actual fact 40% increase over the 15ES you guys got.

I have the 15ES 230V model but the facelift model with the newer cable and rubber trigger which I think might be tweaked even further as it corrects faster than my 3401(now that I have spent loads of time with both machines).

I'm still curious on the percentage figure between the 15ES and 21 MKII, me thinks 50%+?
 
I was gonna get the 15es cuz the reduced price is very appealing.... But me being the way I am and wanting "the best" I can get I decided the extra $100 for the new guy on the block mk2 was worth it.

Without a doubt, you made the right choice. I bought the 15ES a while back and sold it a few days later.

Please expound on the reason for the quick sale of the 15 ES. You seem to be a fan of the 15 Mark II yet were so turned off by the 15 ES that you sold it in three days? Are the two tools really that dissimilar?
 
I decided to get the standard 15 ES and spend the extra $100 on some Lake Country ThinPro pads and this HD Speed everyone is raving about. I got a $15 bottle of HD Speed to go with it. Thanks for all the input guys.

You'll be good with the ES, man.

Depending on the pad, I found the pad rotation to stall very easily with the 15ES. The Mark II power has been upgraded significantly, therefore, less prone to pad stall.

Autogeek's description that it "feels more powerful" is both accurate and inaccurate...

Yes it feels SIGNIFICANTLY more power because IT IS SIGNIFICANTLY more powerful.

The confusion is because tool makers and tool sellers (since very few tools are actually made..) in the USA have attempted to draw a correlation between watts and actual power.

Watts is a measurement of how much energy the tool sucks off the grid just like MPG is a measurement how how much fuel (energy) your car burns to move down the road. At least with MPG, the EPA has designated certain standards to allow measurement for comparison. If you idle around in high gear at 30mph on a downhill slope you will generate a very high fuel economy rating. If you run it full throttle in low gear up a hill you will generate a few low fuel economy rating.

Wattage is similar... If I run the tool under very light load it will pull very little energy and thus have a low watt rating. If you lock the spindle of the tool and run wide open it will suck a huge amount of energy off the grid and thus have a high watt rating. The problem is that there is no standard for power tools, and since marketing tells people that a high watt rating is better (this is the same as marketing trying to convince people that a low mpg rating would be better) some creative techniques are used.

In fact, a lot of power tools will claim a high rating, but under full load they cannot pull anywhere near there claims.

Both the legacy BigFoot Polishers and the MKII Polishers will pull a maximum of 500w under high-load, but pull significantly less in most situations. However, the difference is torque (twisting force or working force) is different. The MKII produces 30% more power torque while drawing the same energy as the legacy.

Imagine we have two cars, both which get 20 mpg city (watts). However one produces 200 lb of torque and the other produce 260 lb of torque. Both have the same energy consumption rating, but one is more powerful. I would leary of a marketing company that tells you that a third car, with 10 mpg and 200 lb of torque is better cause they burn more energy.

Good to know, as the power of the ES15 was NOT my cup of tea! IIRC, the power jump from the ES15 to the Mark II 15 is greater than the ES21 to the Mark II 21.

Wish the Duetto was upgraded. I would have purchased that before any of them.

While the official advertising is that the tools are 30% more power... the LHR15ES actually sees closer to a 40% bump due to the reasons Zubair accurately described.

Whoa, seriously??

To be clear, on speed 4, the Mark II 15 will have ~40% more power than the ES15 on speed 4?
 
Yep as Todd mentioned above, getting my 21 MKII in a couple weeks, never been so excited in a loooooong time :-)
 
I think the Mark II with 5" backing plate is prolly my best choice.

I think its almost everyones choice lol. Rupes will probably start selling it that way me thinks as its the most correction one can get from the Bigfoot range, 21 MKII with 5" BP.
 
I'll tell you the real deal.

I owned an original 15 - and now a MK2. I did a crude video review of the Mk2. I'm too lazy to link it - but it's on Autopia (and You Tube). Yes, the Mk2 is worth it IMHO.

Why? Because it is SIGNIFICANTLY more powerful, and can muscle through concave and convex curves the original unit could not. I proved this to myself after using the new polisher on the same areas of my car I used the old. It's not a gimmick - it is more powerful. Dunno how they did it either - but they did it.

I would compare the original unit to a PC7424 and the MK2 to the Griot's garage 6" in terms of the power difference - since most peeps are familiar with these machines.

I had an early MKI - so, compared to that machine; the MK2 has a much better cord, better BP, and a backside rubber resting point. IME MK2 still can stall at lower speeds, but when you bump it up to 5 it's pretty hard to stall.

I just couldn't see buying the older machine - when the new one is much better IMHO.

Just to be clear about the whole "watts" thing. I have said in the past that "watts" matter with free spinning DAs. Yes, in the past this was true.

Why? Because, in the past you were comparing apples to apples. Similarly made CHEAP Chinese motors, bearings, and mechanisms. Since the motors for PC like machines are similar (knock offs), it doesn't take a rocket scientist to conclude that the higher wattage THOSE machines had - the more powerful they would be.

But, Rupes pioneered a new system and new machines. They are a tool manufacturer first. So, in their case - they put in the R & D to change the game. But, if your buying Chinese DA X - you prolly need a 900 watt motor to make it feel powerful.


****please support trans-species humans.
 
I'd love to hear comparisons between the 15 & 21 MKII's from those that have used both. From what I have been told the 21 edges the 15 in speed of correction naturally, but a 21 with a 5" backing plate shifts that goal posts even further.

That's a very interesting comparison, and good one at that that I can relate to....when I went from my PC to gg6 i noticeably felt a difference in power and overall smoothness....that makes me even keener on spending the extra dough on the mk2 15 :dblthumb2:
