I saw those....[:0] Unfortunately there isnt much you can do if he is truly having the ergonomic problems he described. If I find and build one, its gonna be midcontrols and dirtbike bars.
Why oh why didn't they drill and tap the plates?
I would have run the tubes all the way to the spine. Of course I would have also turned little inserts and pressed into the tubes as alignment/strengthening aids and made liberal use of gusseting on the outside of the tubes. There is a tube butt joint in there someplace just waiting to surface. The angle iron continues to baffle. Its setup like a little L shaped spring in the frame. Gives new meaning to the old saying "hinged in the middle" eh?
