eng rod balancing thread

Most important is how you measure the big end vs the small end. If you don’t have an accurate scale and a rod weighing fixture than it’s all for not.

I was wondering about that myself. there's a utube vid on making the fixture (yes it needs to be perfect) & I was thinking of a HF scale, way back I had one & it was just as accurate as my buddys high dollar one.
