Atari Gravitar Restoration 2

Here we are with the second instalment of this Gravitar restoration project. If you’ve been waiting patiently for me to get this cabinet completed, I can only apologise. I have too many arcade projects and so little time! To catch up on the history of this cab so far, take a look here for the original pickup post, and here for Part 1 of the restoration itself.

So you’ll see that we were left at the end of Part 1 with a cleaned up shell:

A good starting point for Part 2. One cleaned up Gravitar cabinet

I didn’t really document it with pictures, but I spent many a rainy afternoon rebuilding the WG-6100 vector monitor. With the help of fellow Stateside collector Andy Baldman, I got the thing working again, after much head scratching and testing, thanks to the working monitor I had in my Tempest cabaret, which I was able to use as a reference point.

With that done, it was time to get the cabinet up to the loft arcade. But before that, I thought I’d get new t-molding onto the cabinet, while I had the space to do so:

I’ve documented this process many times before, so won’t bore you with the details again. Suffice to say, a classic arcade cabinet always looks better with new t-molding!

My friend Rich came over to provide some much-needed muscle to get the beast up three flights of stairs. I traded endless cups of tea and pizza slices in return for his help. I needed it:

Rich and I risked life and limb to get this thing up the stairs at Arcade Blogger Towers

The loft arcade is pretty packed with cabinets these days, but to date, I can safely say that the Gravitar was the most difficult to get up to my arcade room. We actually had the machine stuck on a corner at the very top for a couple of minutes – literally. It was balancing on one step with the top of the cabinet firmly stuck against the sloped ceiling of the loft. It refused to move. Just as we contemplated taking it back down and giving up altogether, we somehow managed to jar it round the corner without too much damage to the walls (well, maybe there was a bit, but I managed to repair it before Mrs Arcade Blogger got home).

One empty Gravitar cabinet. I don’t want to think about ever getting it back down the stairs again. Looks like we’re either living out our days in this house forever, or when it comes to selling up, we’ll have to do a package deal

So with the Gravitar safely in the loft, it was time to get to work on the hardware, getting it clean and ready to repopulate the cabinet. First up, was the power supply:

35688043301_99aecfd3a6_z
This was the starting point. Covered in 35-year-old muck and dust
39837665113_42029d15eb_z
I like the patina on these things, so it just needed a clean up
45887798265_538dac8240_z
A few flight checks before we plug it in. I decided to change the Big Blue capacitor as I had one lying around unused. Replaced all the fuses too as a couple had blown
46750550992_1046ebed7c_z
Testing voltages with the multimeter. Everything checked out. We are good to go!

Next up, time to head to the kitchen sink to give some of the metal work a wash:

31861406877_f9a4ae566f_z
That’s a big box of stuff. Washed the cash box and other metal bits that were safe to soak

Next was the marquee:

The three stages of cleaning
39837668713_4870b20060_z
Had a slight disaster (and learned something along the way). It turns out that 35-year-old silk screened graphics don’t like warm water. Not happy! it doesn’t look too bad. I may consider replacing this with new art, but for now we’ll see how it looks on the machine

Back out to the garage to get the coin door into shape. It came very badly rusted and needed a complete refurbishment:

32105236957_995292b41b_z
Step one, coat everything with Paint Stripper and leave for an hour
33171590918_64f13c25f4_z
The paint scrapes off pretty easily once the stripper has done its work. We’re now ready to respray using Hammerite metal paint from a rattle can. I use ‘Black Hammered’ finish

After three coats of paint to the door, I left that to dry overnight and ventured back into the house to get to work on some other jobs that needed doing:

46995000332_54201be6de_z
Here’s the test plate that sits on top of the cash box. This is the state mine was in. The paint has bubbled and rusted right through. Can’t have that inside my cabinet
32108821817_b64440d284_z
After removing the hardware, I stripped the old paint, resprayed with three coats and put everything back together. A vast improvement!
33161689828_467567550c_z
Gravitar has two speaker grilles, and both of mine are pretty rusty looking. This is a job I probably should have tackled in the garage, but I managed to overlook it
40071954553_0cb17cb8b4_z
I wouldn’t normally recommend spraying paint inside the house, but I had little choice. Masked everything off with newspaper, and carefully sprayed the grilles with smooth black metal paint. I surrounded the grilles with a cardboard box to minimise overspray. Don’t forget to mask off underneath your grille otherwise you’ll find paint goes right through to the inside of your cabinet, or worse still, your carpet. Ask me how I know….

Buttons next. I depopluated the control panel and dismantled everything:

46984833462_17790c2bbe_z
Here’s the buttons from the control panel. Pretty mucky. They’ve never seen water by the looks of it. I dropped them into hot water and detergent and left them to soak overnight
33161687258_d4c2686091_z
After drying them off, I grabbed the drill, put the button shafts into the chuck and spun them in an old tea towel with a spot of polish
46312796424_2b537d7855_z
The clean and polish really brought the colour back to these old yellow buttons. Nice!

Next up it was time to tackle the control panel:

46750552632_79792869f7_z
Here’s the control panel that came with the Gravitar. Looks pretty nice at first sight
32927240678_38ef74e3a7_z
But I wasn’t happy with this. Fairly typical of control panel overlays of this age, the vinyl overlay starts to crack around the edges, and my panel was pretty rough-looking in places
47036869481_0ded00b0c8_z - Copy
Thankfully, I acquired a reprint from This Old Game. This particular reproduction uses the same materials, and the graphics were done using the original Atari film screens. This is literally an exact copy of the original – I had no qualms about replacing it
46984833862_d41c6e93c9_z
So let’s get the old vinyl off
47046863281_22d9e0488f_z
What the vinyl leaves unfortunately, is a thick film of adhesive on the metal panel. Now there are lots of restoration jobs to be done when working on old cabinets, but this is the worst job of all. All told, I spent a good three hours with a scraper and copious amounts of kitchen paper and WD-40 (which I found to be the best remover). I finally got there though

So with our panel stripped, prepped and cleaned, it was time to apply the new artwork:

46312796014_41377b16d9_z
Take careful measurements and mount the artwork to your panel using masking tape
46984829662_e047b2e9ee_z
This is a job for two people really. Fold out and remove the backing film from the top to the middle of the art, then cut it away. Use a soft cloth to press firmly from the middle upwards
46123242205_f0b885984b_z
Repeat the process from the middle to the bottom
47036848341_3b7c984993_z
Get a sharp craft knife and cut out your button holes using the holes already on your panel as a guide. Here’s where you find out if your measurements were correct!
46984828232_54132d90c1_z
With your new art applied and button holes cut, its time to replace the hardware
46995000352_b7d6f79492_z
Et Voila! One spanking new control panel. Very pleased with how this came out
46123241035_dce6bc32c4_z
Thinking outside the box. There was a strip of foam applied by the factory at Atari on the back side of the control panel that protects the monitor glass when its closed up. It came off when I stripped the vinyl art off. To replace this, I used a cut length from a roll of window & door insulation tape. It came with an adhesive edge – does the job perfectly!

Couple more jobs:

46123268825_f8c0604647_z
Got to work on the badly rusted marquee retainer bolts with a wire brush
46123246575_d2a5375907_z
Grabbed the Hammerite paint and gave the tops a couple of coats with smooth black
46984834172_38eca39df7_z
I wasn’t happy with the vinyl on the front of the cabinet. it was badly faded and looked very tired. A great product to bring this back to life is AutoGlym Bumper & Trim Gel. it really makes the vinyl look like new again

There we go, that’s Part 2 finished. Join me for the third and final part, where we’ll get the cabinet repopulated and fired up! Almost time to play some Gravitar!

See you next time.

    This looks great! It’s a pity there’s not a cabaret version, but then it would probably just have boring wood grain on the sides. What would you suggest for volcano buttons for which the plastic has become scratched or pitted? Is there a way to polish or shine that?

    Hey Andrew. There is a cabaret version of sorts that didn’t see a wide release. It was built in the EU factory in Ireland. A couple of examples are out there. Volcano buttons – attach them to a drill bit (or not) and go to work on the cones with a very fine sandpaper, then use Novus polish to bring them back again. Here’s a pic of the cabaret Gravitar: http://www.andysarcade.de/data/picseries/gravitar_eu/pic001.jpg

    Great post, Tony. These are my favourite to read. It is coming along very nicely indeed. Great tip on the adhesive insulation tape, too. Muggy be exactly what I need for underneath my Asteroids cocktail.

    I can almost feel your pain after the marquee cleaning!
    It was in so good condition under his dirty coat!
    Anyway, the work you’ve done on this cabinet is amazing! I especially like how the new paint looks on the test plate
