Paul, I am including the solidworks and a .tif file of the flying buttress tube flange mount I
mentioned in a previous reply. I hope it works. (the file I mean) The band shown is made of 321SS
and stitch welded to the tube. The flange and stub has a single blade machined in or welded on. I
am sure you get the idea. I have also seen similar set-ups with the tube band on both sides of the
tube
