have you looked up homemade lead hardness tester?
Here is the pencil test.
Hate the annoying back ground music.
There is always the bearing/bb test.

I've been surfing some of the home made ones. I like the simplicity of the saeco but am intrigued by some of the inventions I've found on cast boolits and other forums
I don't want to screw up your ad, but I'm going to comment anyway.
I have considered the same thing you are considering, knowing if my lead is of the correct hardness.
I thought I would just use a ball bearing and a small clamp to press into my lead.
Then compare it to a ball bearing pressed into some lyman number 2 alloy.
I would not care what the actual hardness is, I only care if it is near the hardness of the number 2 alloy.
I guess you could weld a nut to the end of the C-Clamp bolt to use a 1/4 inch torque wrench for consistent pressure.
