When I first started out in the hobby I was lucky enough to get a Gay 90's from a local collector for $50.

I got a machine that was fully intact but reeked of years of smoke. The playfield had planking and major paint loss. The backglass had some flaking but not terrible. I managed, with the help of Clay's guides, to get it 100% functional. Then I tore it down and had to do the fabled "degreaser and pour hot water on it" to finally purge it of the deathly stench.

Maybe I should have left the flaking damaged paint but not knowing better at the time and perhaps being too ambitious, I scanned it with the HP 4600 Scanjet and then sanded all the ink off. There it sat for a few years, while I gained more experience at touchups and airbrushing.

Finally this summer I returned to the project. I repainted the cabinet, and then moved onto the playfield. I'll take you through how I did it...hopefully if anyone tries to tackle something like this they can learn from what I did and avoid any mistakes I made.

The starting point was a sanded playfield. After sanding, I glued in the inserts (all new except for the clear orange that I reused) slightly proud. Then I sanded the inserts flush to the playfield. I sealed the bare wood with Createx 4050 UVLS gloss clear. Then the repaint process was to start.

Here I'll detail the tools and techniques I used.

I scanned the playfield at 600 DPI using the HP Scanjet 4600 on Windows 10. I use the Vista 64-bit drivers, it works fine for me. If you have a Cruze scanner locally that would be even better. I stitched the images using Microsoft Image Composite Editor (https://www.microsoft.com/en-us/research/product/computational-photography-applications/image-composite-editor/).

The scan is brought into Inkscape and played in a layer. Originally I redrew discrete parts of the playfield in separate files but I found it was much better to have everything in one file, with one color per layer. For the Black layer I created sub-layers for different small parts as I found it too hard to handle large stencils.

So yes, much time is spent in Inkscape redrawing all the artwork as vector to be used with the Silhouette Cameo cutter.

Silhouette Cameo Cutter -- the workhorse for creating stencils

Full size printout of the black layer on 24" transparent material. A screen printing service did this for me for $30. Without this it would have been near impossible.

GerberMask Ultra 15" paint mask. Also shown is Oracal 813 which is a transparent mask, and transparent MT80P transfer tape.

I also used a very fine brush for some touchups.

The first job was to paint the white layer. If you sand back the screen printed artwork, you'll find that white ink is at the bottom of everything. Other inks vary in their opacity so having a white base gives a uniform look to all the other colours.

In order to paint white, everything that is not white must be masked off. This is accomplished by cutting stencils on the Silhouette Cameo. I originally had visions of laying down a couple of big stencils in one blow. After a few trips to the garbage can that was abandoned, it is just too hard to place and manage very large stencils with the kind of accuracy you need (or at least I found it so). Instead I did it in smaller pieces and got there eventually.

Here is an example of stencils that cover areas of the playfield that remain bare wood.

Stencils are floppy and sticky. To help position them, transparent low-tack transfer tape is placed on top.

Using my 24" transparency of the black layer (taped to the playfield) I position the stencil.

GerberMask also comes in yellow, I'd probably buy that next time to avoid white-on-white problems.

One side of the stencil is taped into position

Now I peel back some of the backing paper on the stencil and cut it off with scissors. Then I can adhere the stencil to the playfield while it remains taped in position.

pasted_image (resized).png

Now all of the backing paper has been removed and only the transfer tape remains.

Pull off the transfer tape slowly at almost a 180 degree angle and the stencils are placed. Push the stencils back down if they are getting pulled up during transfer tape removal.

Here is the fully masked playfield. Took a while to accomplish this. GerberMask really works well and is easy to remove once done.

I painted the white using Createx opaque white mixed with 4030 balancing clear. I used an Iwata LPH-80 spraygun. I was originally going to use Createx paints but I didn't want to bother with mixing reducer and balancing clear. I went with Golden High Flow instead which sprays out of the bottle, plus I got to use the awesome Virtual Color Mixer.

I could have used my airbrush to paint it but for a large area I chose the Iwata spray gun.

After a few coats. If there is one lesson to learn it is GO LIGHT on the paint. Many light coats...if you get the paint wet, it creeps under the stencil or makes ridges, both of which are bad. Resist the urge to rush, light dry layers.....

White is done. Painted in a $60 spraybooth from Amazon, it is actually really good for the price. https://www.amazon.com/HomeRight-Shelter-C900038-Portable-Painting/dp/B011L3DVVO/ref=sr_1_2

Layers should generally be painted from light to dark. Here is the aqua colour painted.

So black is your friend. Generally it goes over the seam where two colours meet. I made the mistake of being too cute and not fully butting up colours that would be covered with black keylines. The sub-millimetre positioning accuracy it required could not always be achieved, leading to discarded stencils or me having to rescan and tweak the artwork.

So the next lesson is leave room for error. If you paint light to dark, the darker colours can slightly overlap the lighter ones. That's how the original screen printed artwork was done. I would have saved a lot of pain had I done this better.

With the black transparency on top it is starting to look like something!

pasted_image (resized).png

Now blue...most of the playfield is this colour. The Golden paints have no problem with taping over, never had any issues with paint lifting at all. No intermediate layers of clear were sprayed during the repaint.

Stencils again took a while for this one.

pasted_image (resized).png

Stencils removed and the black layer transparency on top. Looking like maybe I can pull this off!

pasted_image (resized).png

There's a small amount of royal blue to go down...

Painted!

I don't have pictures of green but it was the worst. My first mix was too dark so I resprayed. I sprayed too wet and got a bunch of creeping leaks under the stencils. If only I had kept up the mantra of LIGHT COATS I would have saved myself much pain. Oh well, it's not perfect but for a first attempt I'm satisfied.

Now orange...if you wonder how accurately the Silhouette Cameo can cut -- very. The only issue is with letters like "A" where the little triangle in the "A" is so small that the tiny stencil bit either gets dragged off by the knife or doesn't have enough adhesive to stick. You can try to put it in its place with the magnifying lamp and x-acto knife; touch it up by hand later; or instead later cut a stencil with a hole and spray the colour back. I did all three.

Here you see that I positioned each stencil individually rather than trying one big one. I had more success with this.

pasted_image (resized).png

Orange is done, green is done, and what's this? Some black down...looking very nice! Again, I would have saved myself much pain if I had not been too fine in my redraw and gave myself some wiggle room.

pasted_image (resized).png

Here is close to the final job...just a few more bits left:

pasted_image (resized).png

If you're wondering if things look a bit off-centre; the original was like that and I left it. Part of its charm!

So I mentioned that certain small letters are problematic. At the top of the playfield are some "A" in black. I need to fill in the little triangle with green. I cut the transparent Oracal stencil, put the little triangle in place and sprayed green. Always mix enough paint to do touchups later and use high quality bottles so it doesn't dry out. I prefer the GerberMask but the Oracal has its place where you can use its transparency to your advantage.

Pretty much all done and all touched up. It is very faithful to the original, I made a couple of small deviations to fix up a few paint mistakes and to cover up some damaged wood. Even though it is the "simple" pointy people artwork, redrawing it all makes you appreciate the effort and detail that went into it. I'm no artist so that was interesting to experience.

pasted_image (resized).png

SprayMax 2K and that's a wrap! Any questions please ask away.

pasted_image (resized).png

There's a first time for everything! Only touch-ups on a Williams Spitfire (1954) and Bram Stoker's Dracula before this.

The repaint itself I'd say 20-30 hours -- much of that was placing the stencils. Redrawing all the artwork -- probably double that.

You can see the cabinet that was repainted with laser cut stencils here: https://pinside.com/pinball/forum/topic/what-are-you-working-on-right-now/page/23#post-5801111

The rest is standard cleaning/polishing. The only interesting thing left is recreating a plastic, which I've done before with success, and pondering what to do with the backglass. It has some flaking, but I know they are very hard to do convincing repairs on. Or I might just buy a reproduction, not sure yet.

Bingo guys in Europe sell a repro backglass http://www.coos.net/bingo_e/backglasses.html

Found a "before" picture:

I’d buy the 15” one — be prepared for sticker shock on GerberMask Ultra too!

But I’d also look at 24” or 30” cutters.

Everything is done with stencils! Perfect results, the vinyl cutter does them with ease.

I left the bare wood ones on for several colours yes.

I did it online from a place in Toronto (https://www.screentec.ca -- check under "Film Output" service). I'm sure you could find someone local to do it.

Nice thing is it mostly requires patience and a modicum of skill -- no talent!
