I have a 4.25 inch diagonal bonded at 3 places on my holder.
It has not let go in 10 years. Just use RTV with about 1/16"
thickness. I use three small pieces of double sticky foam tape
next to the spots where the RTV spots will go. This hold the diagonal
while the RTV drys and give you the 1/16" thickness. RTV is used
to hold optical elements in the optical trade. RTV is used to hold
the primary mirror to the cell in those SCT's
