Further mirror mount update.
The alternative double sided adhesive tape between the wiffletrees and the mirror also allowed the mirror to creep sideways and it fairly quickly resulted in the mirror making contact with the surrounding ring - lots of astigmatism. Tried a mounting consisting of screws to attach to the wiffletrees and silicon adhesive between the screws and the mirror. It worked well mechanically, but noticeably damaged the images, presumably through stress from the hardened adhesive. Going back to the original (functional) arrangement with the high strength double sided tape (the clear stuff) and 4 edge supports. I will just have to live with arranging the alignment of the scope so that edge supports are at about +- 45 deg and replace the adhesive tape every 12 months or so. At least it works well optically.
