What kind and size cans are you guys using for your pipes? I am going to make one for a 46 fx,40 fx, 40 fp, and a Webra 40. I have a buddy that is going to Tig weld them for me. It should be lighter. stronger, and look better as well. I didnt think he could weld on stuff that thin but he showed me that he could weld on a Pepsi can so I argued no further.....John
