Harbor Freight Chicago Electric Dual Action Polisher Vibration Test 

Dual Action Polisher Modification Vibration Test Using A 3 Inches Lake Country Backing Plate And Modified Counterweight.
The reason I modified my Harbor Freight dual action polisher is because I mostly use it with a 3 inches backing plate to perform Headlight Restorations and already had one backing plate flying off the machine. The backing plate came off along with the nut where it bolts in to the machine. The problem was that the vibration was so much that it loosen up the snap ring which holds the nut in place. I was lucky the flying pad didn't strike me on the face. Now, before I go to label my Harbor Freight DA polisher as "A Piece Of Junk" like many people do with HF tools I have to look at how have I've been using the tool.
Using a 3 inches backing plate puts the machine under a level of vibration it was simply not design for; that is not a fault of the machine but from the user. However there is a way around it and it is by balancing the counterweight with the backing plate. That is exactly what I did on the preceding video • Harbor Freight Dual Ac... and that I am trying to validate on this one.
Items that I have used for the modification and test:
Porter Cable Counterweight: amzn.to/2DPkdpi
Lake Country 3 inches backing plate: amzn.to/2Qqp4yH
Chicago Electric DA Polisher: amzn.to/2QsGgDX
Litter Giant Ladder: amzn.to/2Cu5JK7
Black And Decker Table: amzn.to/2QK47yS
The two washers I bought at Ace Hardware and drilled the holes to the specific size needed.
