Bubble Balancer No Cost Mod

This is a no cost mode for this style bubble balancer, I would avoid the Harbor Freight models as I have seen videos of them showing the inside of top piece and they were very poorly finished very rough with grind marks and weights added to balance them.

The Harbor Freight units I have seen have red bases and the ones on Amazon with red bases are likely the same unit and cost in the $60 dollar range. Spend a few dollars more and get the silver finished model that is finished properly inside the top unit.

I purchased my bubble balancer from Amazon, it is silver in color and cost $104 dollars but the inside of the top is finished properly and there are no wights to balance the top unit.

The mod consists of drilling out the hole in the top of the unit to 3/8 of an inch so the head unit will properly pivot on the hard steel pin it rests on. When it is not drilled the unit will not swing freely and will stop after three to four arcs back and forth. After drilling the center the head unit will swing for a long time many minutes. Do not drill all the way to the bottom of the hole just drill a little at a time until the unit will swing freely.
