Big news tonight. I got a lot accomplished today spending way too many hours when I should be doing math.
I got the admin buttons in from lizard lick. Because of space constraints, I had to find some short buttons for the front of the panel. They are Seimitsu 30mm GN's. Unfortunately, they do not quite fit in a 1 1/8" hole so I had to open the holes up a bit. Now they fit fine as you can see in the picture.
To get to the wires, I cut a big rectangular hole in the bottom below the control panel. I totally forgot to install the joystick mounts (which are still in the mail) before gluing things together. I'm hoping I have enough room through that bottom hole to drill.

If not, I don't know what I am going to do. Maybe drill from the top and fill the holes in before painting!?
I cut my marquee retainer system. I will take some pictures soon and let you guys know what I'm up to.
I also cut the plexi for the control panel. It worked very nicely with the router and the flush trim bit. Man, my router is becoming the most useful tool in my garage.
Once all that was done, I assembled some of the boards. I attached the top to the top of the back and the vertical piece that meets the monitor. I attached the front admin panel to the control panel. Etc.
Then came time for biscuit slot cutting. This was my first time using a biscuit joiner and I think I am getting it figured out. Some of my boards are 1/2" and some are 3/4" so I had to keep changing the joiner settings. I did make a few goofs but they are hidden (luckily). I didn't take many pictures of this process as I was too excited to get the arcade assembled.
I put all the pieces together to make sure everything fit. Then I glued everything up, threw it all together, and clamped it down tight. I just went out to clean the excess glue off now that it has had time to film over.
Tomorrow I will get the clamps off and get a few more pictures taken. Later this week I will cut the marquee plexi, install the monitor mount, and install the joystick mounts. Then it is time to get the name and artwork finalized and start thinking about paint.
