I had the link saved, but that was on a laptop that is no more. Seems like it was maybe two or so years ago? For the life of me I can’t recall the details, but was sure it would be good for a static balance.
Here’s a list of hamb posts. Some talk of a home made balancer. https://www.google.com/search?q=bra...gMEGAEgQYgGAZAGAQ&sclient=mobile-gws-wiz-serp
I've balanced drums using our spin wheel balancer. In GM training cl*** decades ago this was an approved method. Attaching the weight is the difficult part.
Seems it was kinda like a bubble balancer of sorts. I looked at the HF one, but via the pics it appears the cone would not be large enough for a hole that’s in a drum.
