Lots of guys have" holed " the junk TOO THIN CMB pistons due to abnormal combustion and the fact that the piston dome between the dished dome and the overmilling underneath create a dome that is flat out too thin . Well Mike costanzo gave me his to try and fix and I am happy to report that the process has worked flawlessly and we are now awaiting field testing . I made a heat sink /grounding /clamp fixture to do this and it worked great . I did not try to replicate the dish in the dome 100 % but did blend in the area welded after trimming on the lathe . The resulting weld sink on the underside of the dome in the area that was " Holed " is now 3 times thicker than it was and does not require any machining to clear the rod upper end .
