This is a little off the "art" topic, but I'm redoing my basement shop (the wood shop, not the welding studio which is out in the "barn") and want to replace two lally columns with an I-beam so I have more clear space to work. I have looked up load-bearing info on some span tables to see what various beams can carry, but I don't know what the current load is. Is there any kind of scale I can put under a temporary column to take the weight off the existing column to see what the current load is?
