I have access to a cnc plasma cutteer, a 100 ton press punch, tig and mig welders, and stainless steel. From what I hear ther really isn't much to these kits other than some kind of stainless steel bar that goes through the mast. If someone has a sketch or drawing or photograpg of these bars I would be glad to see if I could duplicate them. My guess is that I could fabricate them for about $50.00 or so. The rivets I am sure are available somewhere. I haven't seen the kit myself so I'd need to see what all is in the kit.
