I’ve always thought the washer mod was 100% intended to reduce pad stall. It definitely accomplishes that in my experience when working on curvy/complex panels.
As alot of others have mentioned it's not about smoothness. It's about pad stall. The added vibrations is a tradeoff I am willing to take. Great video as always Scott.
Honestly washer mod isn’t really necessary as long as user is adhering to proper usage and is able to keep pad flat. Tool has more than enough power from what I have experienced. The importance of smoothness probably differs from user to user but I would say it does make a difference when using this tool hours at a time and probably also less wear on the tool itself the smoother the better.
@@jrose7381 wrong brother it stall no matter what when encounter just a little curve on the panel and I really hate that because that machine cost 600 hundred dollars
Great video ! Rupes in one of their recent webinars said that they are actually considering making a "mod kit" with a 5 or 6'' plate and their equivalent counterweights because its a popular mod for their 15 and 21mm polishers. (and another way to make more $$ ! )
Best bet is to do a sanding mod. Put andpaper to bp put it on and run the machine for 30-60s. It wears the shroud just so much that you dont have to use washer and you get more performance with less vibration :)
@@dillon599 backing plate. LIke p360. Just putt it 2-4 pieces on top of bf with two sided tape. Then let the machine spin for 30-60s, clean the mess and youre done.
Hey Scott, love your videos. Nothing like it anywhere on the internet! I recently got a RUPES 21 mkiii to replace my Zentool 21e2. To my surprise it vibrates a LOT more and makes more noise... The pad stall is also driving me crazy. Maybe my machine is faulty, causing the vibration? Then again, the Zentool I have is crazy smooth. I'm even using only RUPES pads!
I will never use any Rupes 15 or 21 without sanding the shroud(instead of washer mod). Separating the backing plate from contact with the shroud helps a lot with pad stall.
If someone really feels the need to swap out backing plates the best backing plate that provides the smoothest conditions is the kamikaze beast hands down.
any info on this? i have the 5" and find that it doesnt increase vibration irl. But for 3" id trade slight smoother operation for less stalling and cooler pads.
When using washer mode, the washer used should be thinner than the washer used. The washer must be finely flattened to suppress vibration, not just by cutting the edges. Please test it with a more sophisticated washer.
I wonder why Rupes doesn't make the unit with a factory washer mod ? Is it that it is harder on the longevity of the motor?. I watched a RUclips video of a lecture from Rupes demonstrating the correction not only from rotation of the pad but the orbital motion so that if pad stalls in rotation you are still correcting with orbital type of motion. Would be great do paint correction with washer mod and compare the amount of correction with stock setup I continue use Rupes Pads without the washer mod on my LHR15MK3 . The after market backing plates tried where lighter but about say you used the heavier backing plate out of metal like Kamikaze must really change up the polisher. Scott if that NSX is yours's that must be an origami experience for you to get in that car at 6ft 8.

Great test, very interesting, I'll go remove my washer and cut the shroud, been thinking about it for a while. Thx
Using the 5inch back plate on my 21 till the day I stop working on cars. No complaints here, no washer though just the plate.
Very interesting and informative! Do you have a video that's like this for FLEX polisher's?

What grit and what is BP lol?

It's possible. RUPES machines are definitely very smooth. You can sand down some of the rubber shroud to help with the pad stalling

another good video. Thanks Scott

btw have you noticed decreased pad heat with excel's and does it reduce mini's stalling?

Rupes needs to fix the stalling so we don’t need to do the washer mod
I’ll buy the backing plate
Putting your pad on evenly will reduce vibration.
Awesome as always !!!!
The kamikaze backing plate is butter.
