This guy has done some cool things with beam scales. I didn't want to fill the base of my 505 up with plaster of paris so I used lead shot instead. Makes the scale much more stable. I also got a piece of 1/2" thick by square foot glass to set the scale on and it has made a big difference. I'm going to try some of the other things he has done as well. https://m.youtube.com/watch?v=A2PF2xv_OPs
