Jimmy Ray's MAME Arcade Project - Construction

 

I liked the look of the original Defender cabinet and found the dimensions on the internet.  I based my measurements from that.  I created a grid in excel 49x97 representing the 49"x97" mdf sheet I would be using to build. I used that to lay out my rough dimensions using the Defender as a model.  MDF is normally 1" wider and longer than your standard plywood sheet,  It also has a very smooth finish that should paint very well.   I was basically building this thing from the seat of my pants. I was unsure how this thing was going to fit together, so I built a scale model using black meat trays (you know... the kind you get from the grocery that holds your raw meat).  I licked most of the raw meat off (hamburger .. I think) and built my model. That was a great exercise, all the parts seemed to fit like I thought they should, so the full size version should be a snap.  Right? 
My design was simple.  It needed to be fairly skinny because of the limited space in our game room. I also wanted to keep the measurements simple.  I bought 2 sheets of 3/4 MDF from Home Depot and had them rip them into four 24"x6' pieces and two 24"x4' pieces. That way the cuts were pretty straight (better than I could have done with a circular saw) and they fit in my Rodeo easier.   The 6" pieces were used for the sides and all the other pieces were used the the middle, top, bottom and control panel. I would rip them to the desired length as I needed them.  Everything was going to be 24" wide. Simple...right...
I screwed the two side pieces together, so when I cut them they would be exactly alike.  My workshop was my mothers green house.  I had very little room to work and was working on a dirt floor.  I'm surprised that the thing is straight at all.  Straight cuts were with a circular saw and the curves were finished with my jig saw. All the corners were rounded to make it easier to install the T-molding later. 

I used 2x4's to hold the sides together.  I used 4 to build a base at the bottom. I then put one on the top, back and front.  I also mounted the marquee light.  The main reason for that was so I could see what I was doing.  My only other source of light was the Craftsman trouble light you see hanging from the roof support.  The picture looks very bright, because of the camera's flash.

Once the sides were on I was able to start cutting the pieces for the inside.  That went very quick.  I used a 2x4 as a straight edge and my skill saw to cut.  At this point it is beginning to look like something.  I'm not sure what, but what ever it was it sure was big.
