Pads Hotter Than Your Morning Cup of Coffee

[AaronE]

So maybe the title is misleading, but my pads are warming up to the touch when polishing or compounding on my 21mm orbital. I polish on my machines number 4 setting (3800/3900 OPM), only apply enough pressure to keep the DA on the car, and use three pea size dots of polish or compound (AIO is a swirl as recommend by Mike), and brush my pads off after each section pass and swap to fresh every panel. I use Lake Country 5.5in flat pads, CCS pads, and thin pro (these ones don't heat up much for me).

For those using the 21mm throw orbitals, how are you cooling your pads down or keeping them from getting warm in the first place.

Hey AaronE,

Now I don’t run a long throw 21 all that often so I’m probably not the best one to answer your question but I’ll have a go.

Basically anything that involves friction is going to produce heat, it’s just how it goes. How much heat? Well you’d have to check that with a gauge to know for sure. How many passes are you doing per section? Obviously the more passes, the more heat will build up but I’m of the thinking that what you’re experiencing is totally normal.

Also the thicker style pads will hold a little more heat than the Thin Pros too.

Be sure to have plenty of pads on hand & if the heat build up is still concerning you, try alternating a couple of pads between sections to allow them to cool down. :buffing:

Agree with Aaryn.

And will ad that some polishers also building up heat differently through the gears. That's often why you see the holes in the pads for the longthrows. I have a 21mm longthrow knockoff and it's horrible with heat build up. Will change the grease in it and see if that helps. If I polishing in warmer temperatures I have to put down the polisher between every 2 pads and 2 panels. To let it cool off some before polishing again. Especially when I use pads with no center holes. They tend to be sinking in in the middle easier.

Aaryn NZ. :dblthumb2:That's where I'm at now with my Flats and CCS, I swap them out between section passes to let them cool. I do four passes a section with the 21mm.

You’re using the wrong pads. Using pads made to use with the machine will help. But, TBH, that may not be the whole answer. I’m sure I could use those pads fine on my 15mm. Likely something else is incorrect as well. Here are a few things that will cause heat in order of likelihood of occurring:

1. Too much downward pressure.

2. Too much polish in the pad.

3. Ambient temp of polishing surface too high (think black paint in sun).

4. Wrong pads/ incompatible Velcro’s.

5. Something mechanically incorrect in your set up: BP rubbing, machine broken in some way, motor defective.

Also a 5mm pad on a 21mm machine is not the best idea.

I think when it comes to the wrong pad Theory, the thicker ccs and standard Flat pads from Lake are retaining the heat because the thin Pros don't warm up like the others. I'm also inclined to think as well that the 5 and 1/2 inch pads are too small for the 21 mm throw, and I think I'm going to start buying 6 in 6 and 1/2 inch pads for my 21 mm now that I have it. the motor housing on my DA does not warm up as well. So it's not the gears in the motor warming

Pads getting warm and in some instances hot is normal.

Pads getting hot isn't good but it happens with some tool.

With saturated pads, the "moisture" holds heat in better than air. Air = dry pads.

Also - I don't use or recommend pea sized drops when using an AIO. In fact I recommend the opposite. I recommend you use an AIO like a compound or a polish. I figure the guys that recommend pea sized drops only do demos on flat demo hoods, they never buff out entire cars. If they did, it would take them a LONG time.

:)I use your swirl for the AIO (loving my D166 from y'all!) and pea size for my Compound/Polish.

I just took an infrared reading on the back of my CCS heavy cutting pad and it was at 152°F as the last pass for that pad before switching to a fresh one (one body panel completed with it).

So that’s about 66°c . . . I don’t think that’s unusual at all. The Thin Pro Pads are designed to be used on Long Throw machines but I don’t believe the CCS Pads are. Sure they’re going to work somewhat but for optimal harmony perhaps stick with the Thin Pros or even give the HDO Pads a shot, these are incredibly nice pads.

Maybe someone from Lake Country Manufacturing can chime in with some better advice than I.

Aaryn NZ. :dblthumb2:Well ok! Maybe I was being a little worried just because it's new for me to warm up a pad. My GG6 hardly changed the temp on the pads using them. My new 21mm can warm them up pretty good. So far in my project today, my CCS Heavy Cutting Pads haven't taken any damage or have any "bacon crisp."

Maybe you could try cutting a hole in the center of a test pad in order to duplicate the dimensions & design of the original intended pad, Rupes' pads, or Rupes-like pads. LC's pad version of for the long-throw has a hole. Maybe a hole would help.

21mm with 5.5 inch pads? Pads are 2 small?

21mm with 5.5 inch pads? Pads are 2 small?I think they're just barely sufficient for a 21 mm throw.
