Neverending Project:
Does anyone have the dimensions of the spacer bearing? David has used all his stock for the yoke orders (good news to the dirty dozen), and my game is basically unplayable until I get a spacer in there. I was thinking of crafting something temporary out of PVC pipe until David has a chance to make another run.

If you have a bit of patience I can measure the one on my yoke. I'm currently disassembling it, or should I say _was_ disassembling it.
There I was, all prepared. I had my set of "weird-security type of bits" ready, like my freshly aquired imperial hex-set ready, so I was all set to disassemble the whole thing.
Eveything went well until I had to remove the spring pin. I needed a 9/64 th hex for that. WTF ? Not in my set ! I tried a couple of the bits instead and one was really tight. Had to use my battery drill but it came loose fine.
Then next, to remove the big gear the manual says I need a 7/64 hex. W_T_F ?!?!?! How many of those xxxth/yyyyth hex kinda things are there in the imperial system anyway ?? Of course this wasn't in my set either ! Tried something else, but I was wearing it out a bit so I stopped right away, will have to get the right hex tools......geez....
In metric it is _so_ simple. You have either 3, 4, 5 etc. and in between you have halves AND THAT'S IT....
Sigh....
Anyway, as soon as I get further I will measure it fot you !

Well, they don't go finer than 1/64th of an inch, so technically I suppose there would be no more than 63 sizes in between every inch. ::)
(personally I hate the imperial units, but what are ya gonna do?)
Thanks, whenever you get a chance. I basically need the thickness and hole diameter (which is approx. the same as the shaft). You can even give it to me in metric units, if you wish. ;)

Hope this helps...
Pay attention to the "inside" of the spacer bearing - it needs enough clearance for the flange of the bronze bearing.

P.S. I'm using all of *my* spacer bearings for the assembled yoke controllers. I didn't make any spares above and beyond the first 1000 units. I'll be making some more very soon.

A small update for this one... I rebuilt the A/R II board the other night, since I already had the kit. When I pulled the board and examined it, it was in excellent condition and the solder on the back was actually still shiny. I decided to only replace the electrolytic caps, instead of replacing the transistors as well. After all, the power all tested fine anyway, I was just performing some preventative maintenance on it.
All went well except for one of the larger caps which I inadvertantly installed backwards. I had a weird suspicion about it too... I always double-check the orientation before I pull the old cap, and then I only install one at a time checking them off as I go. In this case I pulled two since they were right next to each other, and they were the same size and all. Well after I pulled them, I forgot which way they went (even though I double checked before pulling them), and the "+" sign on the PCB was ambiguous. So i did my best at matching the new ones with the old ones, even going as far as holding the old ones back on the board and comparing dust "traces".
I was wrong. It turned out they were installed in opposite directions, even though they were right next to each other. I had already re-installed the baord and began testing the game before I realized this. I pulled the board, fixed the cap (I turned it around since there were no signs of failure and it tested good on my DMM) and re-installed. The game still didn't work... Drat.
A little stress and googling later, I found that it had blown two 4-Amp slo-blow fuses in the power supply. to my luck I had exactly two 4-Amp slo-blow fuses left in my reserves. I replaced them, powered it up, and all was good. Phew.
Oh, and I replaced the Big Blue too (with a Big Black). I am stalling on the temporary yoke spacer bearing because David said he will be making some more very soon. I am considering slipping a piece of paper or something in there in the meantime to prevent the bumpers from sticking, so I don't have to pull the yoke apart two more times.
