Flex 3401 Modified Backing Plate

[JustJesus]

Lake Country already makes the 4" backing plate. Flex makes it at 4 3/8. Not sure why Flex would want to make something that is already out there (a 4" version). Heck, not even sure why Flex went with 4 3/8 instead of 4 right from the start. Maybe the same reason?

Then, it seems as if the 3401 is being shelved in favor of long throw machines by people.

I don`t use all of my weight on the polisher. I let the weight of the polisher do most of the work.

Not applying too much pressure to the Flex 3401 is a good idea anyhow; pad-to-polisher housing contact can cause problems and it`s easy to apply enough for that to happen.
