This post has been waiting in the wings for a while but I have been prompted to post by a reply by the Doctor to a question on alt.lasers about parts being suitable for kinematic mounts.
So here is how I have acheived this using cheap or recycled (ie nicked from something else) parts.

I have built about 4 variants of this design 2 of which can be seen in the last image. The projector shown now incorporates 3. the 2 you see with the dichro mount modded slightly and a third that is turning the beam from my twin DVD diode setup through 90 degrees to point it at the dichro.
All of the variants I have made have used the same magnetic spring arrangement that relies on the attracting force of pairs of strong magnets to hold the otherwise unsecured adjustable mirror plate to a fixed upright. most use 4 pairs of magnets but the 90 turning mirror for the dual red is a smaller version that uses 1 pair of magnets only.The Dichro mount is made so the upright is lower than the beam path with the optic mounted in a hole drilled in the green firbreglass adjustable portion that is tall enough to put the dichro into the beam path - if that makes sense!
The magnets are stolen from the focussing part of a cd/dvd drive and are glued inplace with superglue (long before the optics are taken out of thier protective wrappers . The green fibreglass is some really cool and very useful stuff a mate gave me some years ago. its 3mm thick and is the same stuff (but thicker) that PCBs are made out of. It cuts, files, drills and taps with ease and is pretty stable with temperature change. I have also used 2mm aluminium to do the same job.
The greatest thing with this setup is if the tapped hole in the upright for the adjusting screw is snug enough on the screw - ie the screw holds itself and doesnt flap about you can lift the adjustable plate off, clean the mirror and pop it back on without upsetting adjustment/alignment! Well cool.
hope you all like my idea.
