Sorry ladies, didn't mean to leave you out, if you can help, step in. This should probably be posted in the craft forum, but not too many men go there. Not to say they don't, just thought I'd get more of a response here. Here's the deal.......... Lamp made with steel tubing and river rocks, tubing appears to need welding, according to instructions here................. http://www.hgtv.com/hgtv/cr_metal_wire/article/0,1789,HGTV_3257_4243842,00.html Question, couldn't I just solder instead of welding? How about if I replace the steel with copper tubing? Could I get away with just soldering the copper tubing? Would that be a strong enough bond? And if you have an interest, more lamps made in the same manner here........ http://www.festaco.com/tablelamps.html You could check out the other products as well. I have no connection with the site, just looked after seeing the Lamp instructions at HGTV. .
