    Nice work, love the beveled edge and step. I just did something similar for my monitor 5's. I just used some stainless drop from one of our lasers though. I might revisit in a couple of months after seeing these.
    Side note: have you thought about making a counter bore and mounting the neutrik connectors on the inside? That way it sits flush to the surface.

    The 0.5" deep thru hole affords the most sealing surface. The counterbore would be neat if they didn't leak air.
    I'm not even using/needing the Neutrik gasket.

    Thought I read a recent post that the Neutrik 4 pin are not air-tight themselves?

    Certain Neutriks are air tight such as the ones I always recommend. Check the spec sheet.

    Got a couple sets of the billet Monitor plates done.... I also rotated the mount bolt holes 45 deg. on these. It just makes them even easier to install by drilling into fresh MDF.
    I ordered the Dayton Gold posts to see what sleeves/spacers need to be done to install...

    I've cut a couple of the old early 5jr X-over cups off with the lathe, but these were only held/sandwiched together by the terminal mounts. Instead of cutting down the plastic and gluing to back of plates, I decided to glue some 3/16" high impact polyurethane foam to the other half. When it dries I'll glue it to the billet with Aleens.... Simple and isolates even more vibes while making clearance for the binding posts, and moving the X-over another 0.625" rearward....

    Is vinyl tape ok to use as the thru-hole insulator?The Daytons are an oddball 0.280" dia. knurled shank and I only have 0.25" dia. sleeves ATM.

    shrink tubing? I would think tape would be fine just tossing out the tubing as another thought.

    That's a good idea. The knurled area continues directly into the threaded area at 0.240" dia.

    Was playing at fairly loud vol. all day and started hearing a rattle. Thought it was my CRS knocking over sockets in the tool chests again. Nary a situation. Discovered the factory inductor nut came loose, so installed longer stainless hardware with crush washers and added anti-vibe pad to it...problem solved.
    While in there, I wondered if I should solder in the fastons at the Neutrik terminals? Do these tend to vibrate loose? They can slightly wiggle side to side but cannot pull off easily.

    Some Neutrik sockets can take the heat from soldering, others can't. It appears to me that yours can't.

    You can always crimp the rolled edges of the faston a bit to tighten the grip.

    Now those are the kind of solutions I don't mind having delegated. They're snug now.

    I was redoing the tweeter leads in 16g OFC and I removed all the set-pins in the X-over terminals and re-crimped then shot with deoxit....
