Two of the threaded inserts on the mirror cell have pulled away from
the particle board. It has the nails heads for the push screws to
contact. Two of the threaded inserts in the back plate where the
collimation screws are, pulled away from the wood awhile back. I
repaired them by drilling a 1" hole & filling with hardwood dowel,
redrilling & installing new threaded inserts, seems to be holding okay.
Maybe I should do the same on the mirror cell as well? Getting tired of
messing with it. I realize a new light weight cell will mess up the
balance & create new problems. I see no flex problems with the thin
mirror on only 3 points, but I suppose it's there, star test & images
look good. Seems a layer of carpet glued to the wood mirror cell in
place of the 3 discs might support the mirror better? The tape & large
hose clamp seem to work okay supporting the edge. Wondering if drilling
some extra holes in the back plate would help with cool down?
