I'm having some difficult finding a place out here, do you think they would turn another pair?I've had it done.. They are hardened steel. The first time my machine shop didn't realize and busted something..

I will have to get my parts back first. I am trying to get them repaired/remade.I would love that. I need to re-make both Caps from scratch. I was going to wait until I had CPOs and joysticks before doing that, but having the measurements and full pictures of the parts and the inside pan of the cabinet side would be really helpful.

I can try to grab a pic, but I have to disassemble the coin door again. It was stamped on the back of the CoinCo metal plate and slightly transferred the wood of the coin door underneath.That's great - it would be correct. Can you take a picture of it and also a picture of where you found it?

Thank you. I really lucked out that the holes were the perfect fit for a 1 1/4" dowel. I think the control panels are going to be the biggest challenge.Coming along nicely, I like your fix on the coin door for player 1 & 2 buttons
Tasks that have been performed so far:
Board Set:
I sourced a Rev D CPU board that had "memory problems" from QuarterArcade. The board was in good physical shape and other than the battery holder having been removed, and appeared to be clean of hackery. Hooked up the CAT BOX, and my Stargate ROM board and started doing some checks. Replaced all of the RAM, cleaned the sockets, and the memory errors were gone! Booting Joust gave random RAM errors, but the game would start. Within about 15-30 seconds there was graphic glitches and reboots. I tried with Robotron as well, same as Joust. Still on the path to do easy things, I swapped out the video decoder ROMs. All the Memory errors were gone, all the graphic glitches were gone, and all 3 ROM boards booted with no issue and ran RAM tests for about an hour per board with no failures. Installed a coin battery mod, and (I think) I have a perfectly working CPU/ROM board set.
Widget Board:
In my box of random Williams parts, I found a widget board that I had been trying to get working, but had stopped for a bit due to lack of time/parts. Turned out there were two issues with this board. Pin 1 on connector 3J2 was stuck active, and pins 4 and 5 on connector 3J3 were connected to each other. The pin 1 issue on 3J2 was due to a bad 4049 at IC7, swapped that and all was happy again. The tied pins were annoying, mainly because the obvious and right solution was completely overlooked by yours truly. I started poking at the signal resistors, the caps, the pull-up resistor network, and none of that was the cause of the issue. The 4049 these lines were tied to seemed to be working correctly, so I was stumped. Looking at the back of the board where all the signal resistor are located showed an area on the board that looked mangled. The pads between R7 and R6 looked like they were incorrectly screen printed, and were connected. A little bit of careful cutting with a #11 pen-knife, and the issue was resolved. Another board ready to go.
Misc/Power Supply:
I have a sound board that I rebuilt a while ago, just need to make sure I have a proper ROM for it.
All that is left was a power supply. Thanks to @SCUBA King I was able to get a power supply and after a re-build and jumping to be a Cocktail power supply, the set of boards are complete.
I have most of the parts sourced for this, but there are certainly going to be some fun adventures with some items. While I have a solution for a power transformer, I would love to get an actual Williams Cocktail power transformer brick and mounting plate.
Items that are needed:
Wiring Harness - Sourced
CRT - Sourced
Cocktail Power transformer and power supply mounting plate.
Sound Board rails - Sourced
Joystick shafts, yellow and blue (the sticks in the machine are 8-way microswitch sticks for the JROK)
New CPOs
Cocktail Instruction Cards - Sourced
Light sockets for all the GI
Wiring strip and resistor for the GI
More things that I am sure I am overlooking.
This is going to be a lot of work, but also a lot of fun. I am really looking forward to my first real project machine!
Special thanks to @lilypad19 who has been giving me advice on the side and for all of the Joust Cocktail restoration photos. Having them as a reference has been INVALUABLE!

Thank you for the offer. I wish these worked, but the upright joysticks are too tall for the cocktail cabinets. The mechanics won't fit below the control panel.Will these help you?
They were rare, but also very easy to convert. Many survived due to this reason. If it weren't for the funky monitor shroud, it would be a great candidate to make reproductions.Does everyone have a Joust cocktail? For being rare, these seem to be everywhere!
Cool cabinet. Nice to see them being brought back to original.
My only stumbling block right now is the control panels. I need new CPOs, proper joystick bats, and to build the actual panels correctly.
I have a workable temp solution, but that will be the difficult part to finish.

We sent my control panels and start plate art to TOG a couple years ago. Rich has scans of them so I know its possible the art could come back on the market.
Funny enough I got a shipping notification from @ThisOldGame today for the Joust CPOs and start plate!I called them a couple months ago to check and they had just done a run when I contacted them. They hadn't put them on the site when I called. I purchased and received all three plexis. My "super attention to detail" eye caught a couple lines that were missed on the start plate (ostrich's foot on the player one side is one of them). That being said, I am still happy to have them.
