I cannot find the posting, so if you are the one with an original 3- stack Thant would like to convert to a 5 stack or 7-stack, I may have a solution by mixing in some of my metal drag washers with 0.5 mm thick Carbontex washers that I have cut. Please let me know who you are and when time permits, I will post the washers and sequence.

Not my post Bryan, but I had the same issue with an older 114H. I simply used one of the original 3 stack metal keyed washers, which was much thicker than the 5 stack washers, as the first keyed washer in the sequence. That raised the bottom of the stack enough for the slot to grab the first eared washer.
