Bernhard, many thanks for the photos and the update. Do I take it that 8 blobs of epoxy was not enough, and that you now used maybe 18 or 20 more blobs?

(I have an HP-25 which was disassembled before I got it, and I can't tell how many of the little plastic pillars would originally have had mushroom heads and be holding the keyboard together. Do all of them need reconstruction?)
