in other words if it takes 1 ounce to move one side a noticeable difference, your accuracy will always be about +/- 1 ounce.
Not saying your ISN'T accurate enough - just that if you want to know, it's easy enough to test.
Just put some typical weight on both sides to get it perfectly even. Then add small weights to one end to see how much it takes to get it to move an amount you can notice.
If you don't have known weights to test with, try dimes. A dime is 2.268 grams. If that's too heavy, cut one in half - not super accurate, but close enough.
Once you establish how accurate it is, your other problem is consistency. Take the weights off - try it again and again. You might find it takes a different amount of weight each time to offset it.
And then on top of all that- the accuracy (friction) will change with the weights being compared.
If you're always measuring cutter blades, that's great, but if you're comparing items of various weights - heavier objects may prove to be much more innaccurate.
Try it. If it takes one dime to offset two beer cans - it might take 50 dimes to offset two cinder blocks (if you really wanted to hang that much weight on it - but you get the idea)
