Nakedanvil - Grant Sarver Posted January 16, 2010 Share Posted January 16, 2010 Here's some pictures of my steel weight calculator/slide rule. The first one just shows the whole thing. The second is a close-up and I'll explain how it works. As you see, I've lined up 1" over "square". You can immediately see that it is equal to 1-1/8” round. Just above that shows you that it also equals .25 X 4 flat. Moving down to the second row, you can choose a length and find the weight 20” is a little more than 5-1/2 pounds. If I wanted to forge that from 1-1/2 inch round, I'd set 1.5 over round bar, go to the bottom and look at a little over 5.5 pounds and I know I needed to start with 11 inches. http://img64.imageshack.us/i/weightcalc1.jpg/ http://img198.imageshack.us/g/weightcalc2.jpg/ Quote Link to comment Share on other sites More sharing options...
