Well, it’s been a while since I’ve posted so it’s time for an update.
The backbox has been completed, but not after some pain. I had it mostly done when I accidentally knocked it off the work bench

All the joints came apart and I had to rebuild it, doing the best I could to smooth out anywhere it had become uneven. It will never be quite the same as before, but overall I’m happy with the outcome.
Since I decided to go for a dedicated monitor for the DMD, I had to make a panel to house it at the front of the backbox. I will also fit the speakers in this panel. I started by routing out a space for the monitor.

I rounded the top edge of the panel, and cut a DMD aspect ratio size hole where the monitor sits. A lot of the small 7”monitor will not be seen, so that the correct aspect ratio can be kept. I also cut out some round holes for the speakers and routed a square cavity behind them where I will eventually put some speaker mesh.

Here is the mostly complete backbox, and a view from the top showing the hinged back panel and where the monitor slides in. That grill at the back should look better once I paint it black.

And here it is with the rest of the cab. I got some authentic pinball cabinet legs – these make the cab look a whole lot more legit.

Some photos from the back showing the slide out drawer for the PC and the backbox access.

I put all the guts inside for a sanity check and to see if I have to make any adjustments to the cab before I start prepping for painting. Everything fits ok but I will have to make some extra holes to run some cables to slightly different places. Lastly I gave it a test run. I think it looks a lot better than my original 2 monitor setup.

So I'm happy with the build so far. I think it is time to start getting some coats of paint on this thing. My plan at this stage is to throw on a few undercoats first, inside and out. The outside sides and front surfaces I am planning to cover with printed vinyl, so I will spray these with gloss black (I read a smooth gloss surface is best for adhesive vinyl). All other visible exterior surfaces will get a few coats of satin black.
