I'm looking into getting some fractional plates. I don't need them yet but I want to have them on hand. It seems like a set of commercially made plates runs between $50 and $60 a set (5 lbs total), which is quite steep.
I found a blog that mentioned using washers as makeshift fractional plates. They have a 2-1/8" inner diameter that should fit the barbell nicely. They cost $1.90 each (+ shipping). Fastenal lists washers of the same specs as 0.6329 pounds.
I wanted to see what everyone thought of this as an option or if there are other/better options out there.
