Free-Up Recoil Spades (cont.):
Eventually, the steel bands holding the eccentric pivot shafts of the recoil spades had to be cut. The cuts can be seen in the top of each band. This allowed some expansion. Then a hole was drilled into each pivot shaft cover to allow penetrant to reach the inside of each eccentric.
After disassembly, cleaning of the shafts and eccentrics, the assembly operated smoothly. The cuts and the holes in the shaft were then welded closed.
