I have a good number of 45s myself, been collecting them for years. I generally reserve my globe 45s for SE use, since it's so difficult to find a pair that will bias together, even with adjustable bias. I've not had an issue with microphonics with them though.

I friend of mine has a small company that makes the chassis for me and I can highly recommend them: LandfallSystems.com. I do the chassis design in AutoCad and send the .dwg file to Dave. He sends me a complete (flat pack) brushed and anodized chassis. They can do other finishes as well such as powder coating. I do the labeling layout on AutoCad as well and I have a local person with a 65 watt laser engraver to do the lettering/artwork for me.

Nice, thanks for the chassis info. Oddly enough, I found them years ago, but at one point, I couldn't remember them.

I started using AutoCAD back in the 80's... had a licensed copy for testing early PS/2 Systems with the 386 and 387 math coprocessor. Can't believe how many different stepping level 387s Intel sent, before I got one that actually worked correctly with AutoCAD. I'm still using the same code... running on a Model 95 with DOS, as that older version used DOS as a launching pad with the old PharLap DOS extender to kick the 386 into protect mode. I ended up building a custom menu and a large collection of electronic symbols to create all of my schematics with... and another to do the chassis layouts with. I would then use an IBM 6180 pen plotter for 1:1 templates and create the chassis work from metal stock or modified Dynaco parts.

Funny enough, I also have a old friend/colleague that has a CNC router table with the laser burner/engraver. Once I get a bit further on some other projects, I'll be looking to get some anodized work from Landfall Systems for some new designs. Thanks again!

The person who does my laser work has issues with anodized aluminum, but she's got it figured out. She uses Ceracote (I think that's the spelling). It's in a spray can and looks like a tan paint when applied. Laser the images into the coating (two times I think) and then wash away whatever wasn't hit with the laser. The rest is black and very durable.
