Rupes 21 -vs- Rupes 21 Mark II

Nice find. Would love to see a comparison of MK1 with washer mod vs. MK2, I think both will keep spinning.

Agreed. That comparison will be an interesting test of the new vs old machine capabilities.

or against the G21. since it already has more power than the current lhr21, i'm guessing the new mk2 will be on par or the same...

Don't confuse wattage for a measure of performance... wattage on power tools is simply a rating to quantify the capacity for consumption. It does not directly correlate to output or result on the working surface. A well engineered tool will have the capability to produce results with less watts as efficiency is ultimately the game. Excessive consumption really only translates to so much mechanical movement, the rest of the energy manifests itself as heat, vibration, and noise.
 
Awesome video!! I am curious I am looking for another DA. I currently have the Flex 3401 and PC7424XP. Will there be a Mark II for the Rupes 15?

Please correct me if I am wrong with the Model Number as I do not need the Rupes 21 but (I believe) the Rupes 15. Either way, awesome video!!

it would still be a great comparison (no confusion), another company is also coming out with *something* and i can't wait to see how that compares with current and new offerings as well... :xyxthumbs:

You talking about Flex right?
 
i am curious and interesting...I wonder when it will be available to buy.
 
I wonder what the new price on the old Rupes 21 and the new Mark II will be

Will they discount the 21 or just charge more for the new and improved machine?

Maybe the 21 will be discontinued
 
Can't wait to see comparisons to the G21. Looks like they integrated many of Griots features as their improvements.
Exciting to watch!

That would be a completely false assumption. Whether it is the theory of the tool, our innovative counter balancing system, or even the number of holes on our shroud, RUPES is an engineering firm and tool manufacturer.

With the Mark II, we have spent nearly two years improving the design we originated. Unfortunately for our competition, they have copied (sometimes identically) some of the areas we have improved, although I am sure we have helped them to blueprint their next generation as well.

Make no mistake, not only do the Mark II deliver amazing torque to the paint surface, but they draw the least power, run cool, and are extremely balanced.

Excellent reply. In any industry there are leaders and followers. Rupes has led the long stroke da field and continues to advance the science behind it. Looking forward to adding a Mark II to my arsenal of detailing machines. I can see with adding the fresh talent of both Todd and Jason Rose to the Rupes team plus their engineering dept"s commitment , there are many new things coming to the industry.
 
I saw the video and wow is all I an say. Has Rupes finally solved the stalling issue that some of us have experienced. I will wait for the reviews before a purchase but clearly they have listened to some of us who had issues on curves and that is a sign of an excellent company.

Mike P did make a comment that gave me some pause in his review:

"To be honest... there were convex curved areas that required more focus on my technique to buff completely but this was accomplished simply by adjusting how I held the tool in relationship to the panel."

I am not sure what that means but did the tool stall on these curves. I would like to see more videos like the one on this thread to show exactly that issue. I still believe it will stall or slow down on complex curves but even marginal rotation is enough with the 21 orbit.

Any additional thoughts here would be helpful as I am really considering going back to Rupes if the Mark II truly is the closest thing to forced rotation without forced rotation. If that makes any sense.
 
I won't answer for Mike, but add how I've been responding to that question:

The Mark II requires the operator to employ less specific technique to eliminate rotation stall.

Obviously there are those out there with the original tool that have been able to overcome the stall with technique. The increased power output to the working surface just allows for the machine to compensate vs. the operator.

I worked with Mike when he used the Mk.II tools. I will say that he was quite pleased with the performance of the tools although I will leave exact quotes out of this comment because of his position in working with other manufacturers.

All random orbital polishers (large throw tools being more susceptible) will stall in the right conditions. The Mk.II versions are far less likely to stall. However, if you wedge the tool into a concave at an angle, you can stop pad rotation (it is just WAY harder to do with the newer tools).

As far as rotation, a large throw random orbital tool generates at least 80% of its movement on that pad's edge from the orbit, and this number grows the closer we get to the pad's center. Rotation is nice, but not necessary. I have removed P2000 grit scratches while purposely stalling the pad.

I find it funny that the RUPES owners that were bashing the G21 for having a more powerful motor and it not being necessary because the Rupes machine was better and more efficient, what are they saying now...Rupes changed the motor to a more powerful one????
 
Thank you both Todd and Dylan for the responses. As you commented, you can stall the machine on a concave at an angle but I am considering a go all in with Rupes if you can generally answer the following:

a) Is there any way to estimate how much improvement there was on curves? In other words, given I am only a weekend warrior and not interested in "focusing too much on technique" do you think the stalling is reduced by 50 percent, 75 percent or 25 percent.
b) Do you think this tool would work for newbies or weekend warriors who are clearly only taking care of their own rides. Or is this tool geared more to the professional detailer / body shops (where I believe Rupes wants to take their business).

Thx for any comments and the very fact that we have heard from multiple members of Rupes (and nothing from Flex) shows the significant attention to customer issues and that is a company I want to do business with.

Good questions, would love to see the response. Also agree that there is absolutely zero correspondence by any Flex representative/s on this forum.
