OK....then you must have done what ARG did...that being a sequential removal of metal off the bounce mirror mount " Post "....????
One must acheive two (2) degrees of movement....Pitch and yaw...I have been thinking how to shrink down the size of a Flexmount !!! The bottom foot COULD be machined off....and the Flexmount bolt secured from the underside. The underside bore thru could be slightly oversized to retain a small amount of flexibility in X/Y placement on the optical plane ???
The mechanical demands of beam combining can be acheived ....even on a small HH platform.....Really !!! I guess it ALL depends on how small you want to get....and, what you need for thermal managment.
We are somewhat limited....when combining modules....in that we will need a fair amount of metal....for cooling.....and a fortunate consequence is that we end up having more space too !!!...Space for optical combining components.
One final note....It is a typical accepted practice...in beam combining in the Projector Build....to have adjustabillity in your beam steering mechanicals. Such adjustabillity has the down side....that the system may become out of adjustment...BECAUSE... the mechanical mounts have adjustabillity !!! The upside is that If ( When ) the modules/diodes themselves get knocked out of adjustment....one has the abillity to
retune....to realign the beams !!!
Kinda a Catch 22 !!!! But then....Engineering ALWAYS has trade-off's !!!
Yikes....just another rant about the glories...and challenges of " Combiners" !!!

See Pic....It is ALL an issue of how MUCH stuff ya want in da box, how big is your box...and how deep are your pockets !!!!!!!

About the LPM I think you are having the skills to build one for around $50 like this one
