Building an Arcade Cabinet, Part 4: Side Panels

I bought the board to really start making the cabinet!

I bought 3 melamine boards, $50 a piece from Menards. 

Two of the boards in my "building room/vegetable store"!

This Stuff is HEAVY

When I was in the parking lot, I had three of the large particle boards, 4 foot by 8 foot, that I had to load into the truck. I had an employee help me load them into the cart at the store. But in the parking lot, I was by myself. It was an overcast day, and wasn’t supposed to rain quite yet, but was getting misty. The water would destroy the boards, so I was worried. I worked for a while to line the truck bed with a tarp, and then was preparing how to drape it across the top of the boards. It was even difficult adjusting the tarp as it was a large 15x30’ tarp (just the best one we had) and it took some wrangling to lay it out nice in the truck and get ready to lay the boards over it and then cover them up because of the mist.

I was standing next to the truck, sliding around a board, trying to get my head around the best approach for how to lift this heavy thing into the bed of the truck AND not tear up all the corners on it.

As I was standing there, an older man got out of a large delivery truck and started walking to the store. But he stopped and asked if I needed help! I was so grateful. It was even still a pain for the two of us to get all three boards into the back of the truck. I’m sure without his help it would have taken me much longer, and I would have make a big mess of the boards trying to get them in there. So thank you nameless, kind gentleman! You helped me make this cabinet.

Why Melamine? 

 

Melamine is particle board with a special paint coating

Melamine is a type of particle board. Particle board is different than plywood. Plywood board is made from very thin shavings of wood that are glued together. There is still strength from the grain of the wood. In particle board, there is no strength from natural grain, though particle board is still plenty strong. It's wood dust that is ground up and glued together. It's homogeneous, not slices of wood. Particle board is very heavy.  It is tough, but it can break differently than plywood. It's often cheaper than high end plywood I would use for a cabinet.

You would use much finer grain plywood than this for a cabinet (cabinet plywood) but here you can see the wood pieces of plywood.

A 3/4" melamine board that is 4x8 foot, weighs around 88 pounds. The same size plywood piece may weigh around 66 pounds. My cabinet is heavier because it's made from particle board instead of plywood. That's kind of bad!

I made it this way because if you use plywood, you have to paint it. And painting plywood and getting a great arcade cabinet-style finish is a lot of work and takes special tools. 

I watched a lot of videos and read a lot about it, but the issue is like this: Plywood is real wood which has fibers. Painting it is tricky. You paint a primer layer, and now the fibers in the plywood soak up paint, and rise up (very tiny fibers) but it feels and looks rough. So then you sand it down, over and over. Now you paint it your black color, and the same thing happens again. You have to sand it more! And if you want to do two, three, or 4 layers to make it look amazing, you have to paint a sand so much! Youtuber Way of the Wrench has an amazing video on painting his cabinet.

After looking at everything involved with building my cabinet, I saw many special tools and tons of effort involved in the painting part of the cabinet. I decided if I could remove this step of work, building the cabinet would be more of a possibility for me.

 

That's where the melamine board comes in. It is pre-painted with a tough surface.  Yes it weighs more, but the pre-painted part did it for me. If you are not careful, the edges can chip. It does make it tough to cut cleanly. Plywood is better that way. But the enormous amount of painting work involved for plywood turned me away from it. 

How I Cut Melamine

Did I mention it's pre-painted which is great, but is a little harder to cut? Okay, it's not that big a deal, but you can screw it up if you're not careful. Basically the special protected coat of paint is tough, and chips when cut. You need to use fine-toothed cutting tools. That means you probably need special circular saw blades, and maybe even new jigsaw blades. 

New jigsaw blades were worth getting to make sure they were sharp.

Notice all the 140 tiny teeth. This is not a standard blade like I use for cutting simple 2x4s!

I used the circular saw for cutting my straight lines. Then I use the jigsaw for the curvy lines. Yes, I cut the jigsaw parts by hand. I'm good enough with it to make it look good. My straight lines are much straighter though, because I used guides and a circular saw.

My standard blade is 40 teeth. It was worth getting a "plywood blade" with at least 140 teeth, to get a cleaner cut. 

 

The black paint on the melamine makes it hard to see your lines. I never found a perfect solution, but I used pencil sometimes, and a white-paint marker other times.

I made a test cut at the bottom of a panel with the circular saw. My dad and I noticed that the top of the board has chipped edges but the bottom did not, since the blade spins under and upwards (hitting clean) and comes out the top, throwing material away. We decided to proceed, but to remember to simply flip both side panels, so the previous “outside-facing” side that I had planned would be on the inside (since the outside edges looked chipped). 

The Workspace

My dad is retired, but runs a farm selling vegetables. He has several large barns. He also has a barn-store that is pretty big, nice, and clean. And it has power, and lighting. He let me build the cabinet there. Also he’s helping me work on it some too, since he is in the farming off-season. I own a home but it doesn't have a garage, only have a shed. I would not have attempted to build the cabinet in my tiny shed!

The vegetable table turned tool pile.

 

It's very good to have a pair of extra hands sometimes, to have my dad to help. This is very slow and mostly boring work. There's lots of standing around while lines are drawn, measured, re-drawn, and measured again. 

Cuts don't happen fast. When I do one cut (straight or curved) it takes me about 15 minute to set up the cut. That's a long time. It feels like a long time. It feels silly. It mainly involves measuring, but a lot of time is adjusting the cutting guides, and setting up all the clamps on the material. It's very important to take your time.

Cutting the Panels

I made the straight cuts with a circular saw. I used a jigsaw from the curved edges. The first panel came out pretty good. It was very tricky to use the jigsaw and get nice curves. 

First panel is cut!
The dust from particle board is very fine and not good for your lungs. Wear a mask.

 

We used 2 saw-horses to support the bottom, and quickly move them around as I cut with both saws. We did this to give them most support underneath. It’s important to not let the board start to fall, as this would pinch the blade as you cut. (Pinching a moving blade is bad!)

The shape of the "Bumpy Grumpy" cabinet is unique. 
It's just big enough that I can't fit two in one panel, sadly.

 

After the first panel is cut, I laid it on a second board, and used that first piece as a template.

We flipped the panel onto the second board and I traced it. I then cut the second panel like I did with the first. It came out pretty close to the first. Slightly off in places, but I plan to sand those discrepancies down.

Can I play the game yet???

 

The side panels are cut!

Building the Arcade Cabinet, Part 3: Cabinet Design

After I bought the IP rights for Bumpy Grumpy from the parent company Occidental Designs, I was surprised that they kept pretty loose business records. For a company that had a sterling record of professionalism, I was shocked they didn't even have any photos of their own cabinet! And allegedly all the paper designs for Bumpy Grumpy burned during the great Arcade Fire in '85. 

That meant I had to work pretty hard to re-create the design of the iconic Bumpy Grumpy cabinet! You see, having played it as a kid, I could definitely remember some high points of the cabinet. I knew the profile of the cabinet was unusual. And I also know that I had to figure out the angle at which the monitor was set inside the cabinet. 

Monitor Tilt

The first step was figuring out what angle I wanted the monitor. The monitor angle is important because it effects how the average person will stand and position themselves at the cabinet when trying to play. The Bumpy Grumpy cabinet is a full sized 6' tall cabinet. Which means, if you are six foot tall or taller (like myself) you typically have to look down at the monitor to see things. This help explain why arcade cabinets often have the monitor tilted back, down inside the cabinet.

There are some cabinets where it makes sense to have the monitor tilted upright, such as gun game cabinets like House of the Dead. But if you are right next to the cabinet, using a regular joystick, you'll probably be looking down into the monitor somewhat.

I took a look at cabinets through the years, and it seems like older games typically had the cabinet tilted back more.

Nintendo used this cabinet style for several games including Donkey Kong in 1981

Also in 1981, Galaga, by Namco had a more extreme monitor angle.

It did seem like cabinets ended up near 30 degrees in the later years as a good tilt.

While still sorting all this out, I tried out some heights and tilts with my tv monitor in our bedroom to see what would feel good. 

First up, after getting all the controls working, I made sure windows worked on it on the TV. 

In the bottom right you can see the PC desktop that will run the game.

I set my test version of the Control Panel inside my sock drawer. This was a good test, but wasn't sure how to test the monitor tilt angle. The TV is bulky and heavy after all!

I ended up with the right side version, with more tilt backwards.

I eventually rigged up several pillows on my bed, to continue to test the TV, leaning it back and trying the game at about the same cabinet height in the final version to see how it felt. I ended up with closer to a 40 degree angle.

Cabinet Profile

Occidental Designs was always a pretty provocative company and they knew how to turn heads. Most cabinets through the years have been angular. 

Many cabinet designs over the years. Only Burger Time (upper right) had a similar curved top design to Bumpy Grumpy.

But not Bumpy Grumpy. It had a signature circular side panel! Easy to spot, and easy to accentuate with some exciting side art.

Bumpy Grumpy's CURVY design!

Yes, that makes it tough to cut the curves in the side boards, but once you get a template going it's all about the same. That first cabinet is tough to make though!

The red line is the side shape. The black bars are in the "cross parts", like the control panel.

 I ended using Adobe Illustrator to measure things in my picture to get a properly scaled drawing. I really wanted to make sure the actual TV I bought was going to fit, and at the angle I wanted. After some time  measuring, drawing, and checking, I got a decent layout figured out.  

The Build Starts Next Week!

That's it for this week's cabinet update. With all the designs triple-checked and planned it's time to buy some boards and start cutting!

In the meantime enjoy one more picture of testing with the heavy TV on my bed. 

You might call it a "Test Bed".
