Quoted from mof:Hour 67:Removed posts from plastics, and reattached them to new CPR plastics. I started with the three ones that were clear acrylic previously.
I used a soldering iron to heat the post, and then pulled it out of the old plastics.I dremeled away all the splayed metal.I then hand-polished the post, and inserted it into the new plastic.

So how are you attaching the old bell post to the plastic, or aren't you?

Quoted from mof:The fit is so snug, that by simply rotating the post, and pushing it in, it's coming within 1/64" of "fully seated" in there. Screwing it in finishes the rest.
Ideally, I'd like to have a hyper-thin nylon washer in there to prevent plastics from rubbing against metal.

MOF,
I ask because I just went through this procedure for a friend's Black Knight plastics.
We heated up the original plastics with a hot air gun just enough to let the bell post pull out. I then used a needlenose pliers to reshape the crimped end of the bell back to cylindrical. We then put it in the new plastic and ended up using a punch with enough taper to it to flare the metal back out enough to hold in place.
In the end, when it is held in by a screw, it's only convenience that it stays attached to the plastic.
BTW, your work is inspiring. There is a lot of patience going on to get everything right before you go to swapping it all over to the new playfield.

Quoted from mof:Hour 80: installed two new fresh diodes on the L and R flipper switches, to see if the switch matrix issue goes away.

So did the switch matrix issue go away?
Quoted from mof:So far so good. I'm about 1 hour of game play in. If the fix holds, then that would be the second time (for me) that switch matrix problems have gone away by replacing what appear to be good diodes.
-mof
So what drew you to those specific switch diodes?
I'm watching your progress closely because a friend has a CPR playfield for his HS that we will be tackling in the coming months.
My woodworking experience has taught me a pilot hole is almost always recommended as long as it is undersized properly. Sounds like it would not hurt to ream out any clear that has accumulated in the top side holes on the HS playfield before we start ours.
Nothing eats me up more than having to dig out a broken screw and repair the damage from doing so only to have to start that screw again. I can't imagine how I would feel if I broke one off on the top side.
