I thought I would start with some back story. The 'catalyst' for my desire to build a pinball machine--- The first few pics are from my first visit to PAPA 15 a few months back. It was the first time I had seen a real pinball machine since the early 90's.

Seeing all these great old pinball machines brought it all flooding back.

Posted Image
Trophies with working DMD's.

Posted Image
Double flippers. My nemesis!

Posted Image
FIREPOWER! My absolute favorite machine. Ever.

Posted Image
Tournament play: Classics II.

After going to PAPA 15 (and showing poorly) I realized I needed to know more tables and play more pinball. I considered buying a real pinball machine, but really have no desire to try and maintain it. Plus, if I buy one machine, that would only further me being good on that ONE machine. Enter: vpforums!!!

After a few weeks of research and installing Visual Pinball on my PC and getting it to run properly, I set out to find an old pinball machine to convert.

Posted Image
I picked up this old Atari Space Riders by placing an ISO on Craigslist. Only took a few hours to get a response.

Posted Image
This thing had languished in someones very dusty storage space for a few decades. It reeked of old cigarette smoke when I opened it and had a big wad of 30 year old bubble gum stuck to the bottom of it. Beautiful.

Posted Image
Original back glass artwork. 70's ganja-fueled trippy at it's finest.

Posted Image
Original play field, back box and very rusty legs. Cornhole boards not included.

More to come of the tear-down and build after a bite of lunch.

Nice story - looking forward to seeing some more. Once you finish the cab the world of pinball past will be at your fingertips :)

Part II-

Posted Image

Posted Image

Posted Image

Posted Image
Not much to the back box in these old Atari pins. An empty box a translite and a few incandescent bulbs.

Posted Image
The original play counter. Anyone aware of a way to incorporate this into the new Vpin?

Posted Image
Cab gutted and a quick coat of flat black to knock down some of the 'musty.'

Posted Image
Wood filler in the dents and scratches.
Posted Image
Used a wire brush to knock the rust off the rails and lock-down bar. First few coats of hammered black paint applied.

Posted Image
Back box gutted and partially sanded.

Posted Image\
Rails and lock-down finished.

Posted Image
The 'junk' bucket. Many of these parts I would end up re-using.

Posted Image
I always place a multi-meter among the mess to give the appearance I have everything under control. This always puts the wife at ease. Notice how clean and un-handled it looks.

Posted Image
Posterity photo op.

Posted Image
The fun stuff begins!

Posted Image
Putting braces in place to hold 50" LED. I placed them far enough apart to not interfere with the power and connection ports on the back of the TV.

Posted Image
Putting the divider between the DMD and back glass monitor space. I have also cut an access door into the back of box although it's not readily apparent in this photo.

Posted Image
Working on speaker placement on the DMD cover.

Posted Image
Braces for both monitors in place. I had already mounted the monitors in the box for fit-testing and removed them. You might also notice I used some standard latches for cabinet doors on the underside of the shelf to hold the DMD cover in place. This ended up working very well.

Posted Image
A better view of the access panel. Those hinges are way overkill, but I already had them laying around and had no desire to make yet another trip to the hardware store.

Posted Image
DMD panel cut. I gently removed the original piece of trim that held the back glass in place and glued it to the new panel. My thought was to just have a shorter piece of clear glass cut and use the same system already in place to mount it to back box.

Posted Image
In order to get the DMD monitor to mount flush against the back of the DMD panel, I had to widen the access hole in the top of the cab. Used a long jigsaw blade and a somewhat steady hand (well, as steady as it gets) to accomplish this.

Posted Image
Hole cut for sub, as well as removal of some of the original framework to mount a new amp for the speakers mounted in the DMD panel. I wanted the amp close enough to the front door so I could easily reach inside and adjust the volume. Being able to hold one hand on a flipper button and reach the volume knob was the final litmus test.

Posted Image
If you'll look at the back of the cab, I have cut a hole to house a simple subwoofer amp. It meant routing the speaker wire outside the back of the box then on to the back of the DMD mounted speakers, but I preferred this so I could easily get to the subwoofer frequency cutoff and volume. It's not the most elegant solution, but it's the back of the box so no big deal.

Posted Image
When I 'gently' removed the original trim that held the glass in place (the piece I glued to the top of the DMD panel), it 'gently' ripped the bottom of the back box to shreds. I had to pull out all the shards of plywood and apply a heavy dose of wood filler.

Part III

Posted Image
Placed some of the hardware to figure out where I was going to place the button holes. The positioning of the red (magna-save) button on the side was a big mistake because the width of the monitor interfered with them. I ended up moving them lateral of the white buttons.

Posted Image
My wife was NOT happy about the amount of sawdust I was tracking into the house. Not happy at all.

Posted Image
A better view of the sub amp mounting hole.

Posted Image
This is Jon, one of my 3 boys. They couldn't wait for me to get this thing working. Jon is planning on going to Pittsburgh with me next year. He's really taken to the pinball.

Posted Image
Here you can see more clearly the part of framework I removed for placement of the audio amp.

Posted Image
Back box assembled and ready to be painted.

More to come later this evening...

This project is looking good, and having family interested in this hobby is a major plus! Thanks for sharing the pics!

I could have been smart, but I never learned anything by being smart!

Part IV

Posted Image
Button holes finished.

Posted Image
Two coats of primer.

Posted Image
Top-half inside painted with hammered black.

Posted Image
Back box painted with black lacquer.

Posted Image
Outside painted with black lacquer. It was at this point I realized I'm not good at the whole spray paint thing. Oh well. This is my first time with most of this wood-working stuff.

Posted Image
Starting to look like a proper pinball machine now.

Posted Image
Comparison of the 1978 speaker with the 2012 speaker. The one on the right goes all the way to 11.

Posted Image
It's best to mount your HDD's right next to the sub, or so I hear.

Posted Image
Power, audio and back box monitors all installed.

Posted Image
De-cased 50" Samsung. Fearing I would really screw something up and I wasn't saving enough room to get past the flipper leaf switches anyway, I opted to RE-case this thing.

Posted Image
First time turning it on. Still had plenty to finish and tidy up. That's my youngest son, Asa. He was bouncing off the walls to get his paws on those flipper buttons.

Posted Image
Wiring 5V to the switches.



Posted Image
And finally, we have come full circle. Once again, me standing next to my favorite pinball machine. FIREPOWER!

The last remaining item is to install the mot-ion, if it ever actually gets here.
Thanks to everyone who has contributed to this forum. Without all of your pioneering work, there is no way I would have been able to pull this off!

Thanks again fellow pinfreaks.

If I understand correctly, the 50" Samsung cased, fits in that cab? Or is it sitting on top as some do?

No, it fits INSIDE the cab. It is resting on the two steel braces you see about midway through the build.

It is a very tight fit though; only about 1/2 inch clearance on each side. I have to remove the flipper buttons and leaf springs to lift up the monitor.

I have i believe a similar sized Atari wide body, so this is good news to hear. I presently have a cased 42" and was thinking of putting in a 46", now I know I can :). Really nice build, congrats again.

Many thanks.
I'm not happy with the paint job, but I've just got to get better at it. After my wife cools down some, I may end up trying another build.

I got an email from NanoTech saying they had worked out their supply issues and that the next shipments should be going out the "week of Oct. 8." I've been watching my mailbox all week but no joy in the Mot-ion!

Driving me crazy!
