Ok, so now I'm starting to mentally plan the stages of building a projector.
One thing that has occurred to me is that some of the spacing of components (laser aperture to galvo block, dichro mirrors to galvos, etc) is very critical.
How do you go about aligning these things, and then how do you make up the parts for it?
I'd have thought that having some kind of adjustable bed for the laser to sit on wouldbe easiest, you could just screw it up and down as needed, but I notice that lots of you guys seem to have machined blocks under your laser sources. Do you get these made up specially, or can you buy ally block, or fixed height heatsink easily?
