LC backing plate comparisons - new(er) DA design

Due to some recent posts regarding Lake Country DA backing plates coming apart, I figured I would make this post to clear some things up.

First off, I mainly attribute failure of the "old" design to both the newly designed DA machines (7424XP, Griot's DA, G110v2, etc) and their generous amounts of power, and user techniques. A prime example would be the KBM (Kevin Brown Method). Not bashing the KBM at all, as it's a very effective technique, but the fact of the matter is, it's harder on your tools than more traditional methods.

Here is a picture of the older LC 43-125DA, as seen on our website.

In comparison, this is what the NEW design looks like. You can clearly see why these backing plates are stronger - they have 6 rivets holding them together.

When you order any of the Lake Country backing plates from us, you will receive the newest version!


Another problem people were having was the rotary backing plates coming apart. I've never had one come apart using an actual rotary, but we do sell DA adapters. Before, this wasn't an issue, but once again due to more power and more aggressive techniques, people began running into problems.

This is the LC rotary plate. You can clearly see that in comparison to the DA plate, it is NOT made to hold up to the excess vibrations that a DA polisher will produce. It will be fine for waxing or light polishing, but for compounding, or using the KBM, I would NOT recommend using a rotary plate with a DA adapter on your DA polisher!

Hope this clears a few things up! :props:

Good paint about the DA adapter. Also when using a rotary BP to DA adapter your fingers are open to the counter weight spinning around and could result in some pain!
 
I have the new LC 5.5 on my Griot's DA, let me tell that thing has some power. I'm very happy with the LC backing plate...
 
I have the older 43-125DA Backing Plate still in the original Plastic.

Do I get a new one, or do I just use this one, until it breaks ?

I bought it on 9/7/2009

How far back in time, would AG go ?

I have used my old style LC 6" backing plate via the Kevin Brown Method, with both foam and Surbuf pads.

I simply reinforced the unit by taking out the nylon washer from the screw threads, then fill the crevice around the screw head inside the backing plate plastic with super glue. The super glue polymer fills the crevices thereby reducing flexibility of the screw head, improving its strength and reliability.
 
How is the KBM harder on the backing plate?

The KBM is harder on EVERYTHING including the machine. I don't care if it's a PCXP, putting stress like that on ANY machine is hard for it and will shorten tool life.

:iagree: No doubt! It's logic guys :)
