New Rupes LHR75E Mini in action at SEMA

Interesting...according to this spec sheet (assuming this is final production data):


the minimum opm (rpm) for the Duetto is 4000, and maximum is 5500.

Compare that to the Rupes 15: 1700-4800 rpm, and the Rupes 21: 1700-4200 (although I've also seen 5000 as the max in some places).
So the duetto, in terms of OPM, is always on the high side of the OPM range, even when the speed control is set on low (or I guess that's how to interpret this).

I guess you could emulate this on the 15 and 21 by only using settings above 4 or whatever, and it's a tad short on the maximum rpm. However, most people seem to be using the 15 and 21 below the max speed anyway.


That IS interesting, considering Meguiar's MF Correction System is designed to work with 4800 opm in the correction stage and 3800 with D301 in the finishing stage.

I know it seem to work well, enough so that Mike has offered to be the conductor of the train (the Rupes train). ;) I just wonder how the heat buildup is within the pad, and especially at the backing plate side of things. :dunno:

Being as the engineers at Meguiar's went back and designed their system to work as an integrated design, including the backing plate and Velcro system. (In an attempt to stop the heat buildup that was causing early pad failure.)

Perhaps Mike, or someone else that has worked with the machine could chime in after some testing on JUST the heat issue. :idea: (We know the correction aspect works.) ;)

Would also be interesting to know how other manufactures feel about operating their pads, compounds, or both at only the higher speeds full time. Guess if we all work our machines at speeds 5 and up all day then it's not an issue. :confused:

Makes one wonder if the engineers at Rupes tested with the most commonly available pads on the market or designed it ground up to work with ONLY their pads?

Just a bit concerning when you have hundreds of dollars worth of pads and suddenly you are faced with reinventing the wheel. (Says the guy with a hundred or so pads.)

Need someone to chime in on this thread on Thursday and remind us to check the surface temp when using the new MF pads on the Dodge Charger. We have a Thermo Gun in the garage.

Marco told me it creates little to no heat.

Marco told me these are their exclusive designs for their tools.

Mike,
You are a legend in this craft and people value your opinion, with that said when you are king of the jungle people will always attempt to see where they stand in comparison with you. You have helped myself and my shop in many many ways. Like you said the personal preference is just that. If YOU say a product is amazing then I'm going 100% on your word and buying it. I have many polishers and as they come out will buy many more. That's the entire reason I am on this forum. To get the insight on the best tools, products ect... Thanks for taking the time to respond and thank you for all that you do.
 
Really sorry for misquoting you Mike I read the thing a while back and I know "bogging down" was said somewhere in the write up although it wasn't the main focus of the post.

And for the record, I never took it in any negative or other way that could be confused as something negative. This forum is HUGE and there are hundreds of thousands of posts and now days one of the hardest things to do is to remember where everythings at, for both you and for me!

(Note to self... hang in their memory)



Mike,
You are a legend in this craft and people value your opinion, with that said when you are king of the jungle people will always attempt to see where they stand in comparison with you.

Statements like the above always can always be a little uncomfortable to read and also to reply to in such a public forum. Thank you for your compliment, statements like yours are always nice to read and I use them to remind myself I started out in this industry exactly like everyone else and that's knowing nothing. This is also why I consider myself a perpetual student... too much new stuff always being introduced, there's no way to know it all.. never...


You have helped myself and my shop in many many ways.

And first hand accounts like the above are in fact the most rewarding parts of this job.


Like you said the personal preference is just that. If YOU say a product is amazing then I'm going 100% on your word and buying it. I have many polishers and as they come out will buy many more. That's the entire reason I am on this forum. To get the insight on the best tools, products ect...

Thanks for taking the time to respond and thank you for all that you do.


And the above is just as powerful a post as anything ever posted on this forum.

Sometimes I have to walk a very fine line in that I represent over 70 companies and thousands of products and these lists are growing every day. I also need to be true and honest to myself and to this forum and everyone I interact with, in other words... the world.

So what I wrote before was I was never on the Hype Train for the Rupes 15 and 21 polishers. I like them and I like how they work, in fact I'm amazed at how well they work considering the technique is 100% exactly opposite of everything we have all practiced all of our lives with all the other tools.

I've also watched for the last year to see a lot of people in this industry really throw their weight and reputations behind these two specific tools.

Me? I like them, I use them and I even teach classes on how to correctly use them but I never became the fan boy for them like I've seen displayed by others. Nothing wrong with this, it just shows me something about others.

When it comes to the Rupes Duetto, I really like it. I've been using the Porter Cable as long and in most cases longer than anyone still breathing. I was working in this industry when it was borrowed from the wood sanding industry, a foam pad was slapped on it and it was introduced to the paint polishing industry.

In fact I have an article that covers this topic here,

The history behind polishing paint with a DA Polisher

W6000EarlyDAPad005.jpg



I think the above article is the only one like it in the entire forum world and a person would have had to been there and done that in order to write about. By "done that" I mean calling on body shops and showing them how to use a air powered DA Sander to polish paint because the PC had NOT been introduced yet.


I also posted that I didn't know exactly why it was that I like the Duetto as much as I do but after attending SEMA and talking to the engineer behind its design I "think" I now know and that's because it has smaller orbit stroke AND a faster RPM rate. At least that's what I understood Marco to explain to me.

You still need to use perfect technique when using these types of tools and there's still a limit as to what these tool and any tools for that matter can be expected to do.

But now that the Duetto is public knowledge I think you can expect to see more write-ups from me personally and the cars I work on being buffed out by this tool.

In fact, I have a customer car this Saturday to detail and I'll be using the Duetto to buff it out and Black Label Diamond Paint Coating to seal the paint.


and thank you for all the nice things you said and all your positive contributions to our forum in the professional manner in which you post.

The older I get the more I appreciate a person's professionalism in the Cyber-World than their detailing skills.

I am working right now taken my lunch at the body shop. I brought my Rupes 21 with 5" back plate. And it is keeping up with the Dewalt :xyxthumbs:


I wet sanded a repainted fender and bumper 1500, 3000

I tested out the Rupes with 3M rubbing compound and fine polish and it came out very easily and great.
 
Just to note,

I took some good before and after pictures of the condition of the paint on John Mayer's 1935 Ford before I worked on it. I have not had time to process them as I know it will mean more when you see the before condition versus the after condition.

I'll get those posted first thing tomorrow morning as I'm sending out an e-mail blast to my e-mail list and want to include those pictures.

Here's the placard at the back of the car while it was on display, as you can see this was a very high dollar build. It was a runner-up for the 2013 Ridler Award.
