Man 14 pages of stuff and no one offered how to make the frame better. Metal, get yourself a piece of cromemoly about an 1/8" thick, make a plate shaped like the front of the frame with a hole in it to match the whole for the pipe. Make the outside about a 1/4" smaller all around the edges, then weld it on the front. This will add to the strenght of the frame. Before you weld the plate on, grind down all the high spots on the front first. Good luck man.
