    The parts are all here. I guess it's time to get on with this. The first hard part is knowing where to begin. The scanner block? The heads themselves?

    The second hard part is psyching myself up to apply that damn drill to the pristine baseplate for the first hole and then, hoping I continue to drill all the holes in the right spots.

    I hope you have a drill press! Also, I don't want to tell you how to do something you already know.... But working a tap is an art. You cut about a quarter to a half turn at a time and back it out. Use cutting oil. There is even a specific formula for Aluminum. Compressed air is great for blowing out the cuttings. Run the tap in and out until it moves freely. You should be able to thread a bolt of the same size and thread with your fingers.

    hey brad! looking good there!

    i would start with the green, fix it in place, then fix the green bounce mirror and then get the beam on the scanners.
    then the blue and the red and the dichros

    keep the shutter for last

    I fix all the heads first. Then the scanner block, then I add the steering mirrors and dichros one at a time working towards the scanners. This way you can align by eye as you go and you reduce the chance of breaking something fragile. I use good quality taps in a handheld electric drill but start with coarse one and work up to the fine one

    You are using Bonetti's defense against me, ah?

    I thought it fitting, considering the rocky terrain.

    Beautiful. Thanks much! And that also makes sense. The one thing I do need to do still is shim up one of the heads as it's just a touch lower than the others but, I think I've got some thin aluminum that will work.

    Next dumb question is, do you typically put in your drivers and power supplies first and finish the underside or, do you do the modules and optics first? I've seen pictures where people appear to do the optics side first then flip it over and support it on a wooden form to keep it steady and then work on the drivers/power.

    Personally I drill, then dry run the fixing position, then remove everything again until the only thing left to do is the optics mounts. Then fix everything, mount the plate and do the optics.

    Do all your lasers have the exact same beam height? If not you will never get near field right without shimming them. Just checking.

    Actually, you can just add a steering mirror for the furthest 2 heads and forget about the shims. This was by far the best solution in my big RGB

    Agree 100% but that isn't how he had it laid out.

    Ah, I didn't see his pic earlier as work block some images. Food for thought anyway
