Quoted from Billc479:I am bothered by you saying that only one side is coming up. The hasp is in the center, so both sides should come up.
Is the plastic edging for the back glass down all the way onto the glass/translite? I’m wondering if part of it is wedged between the glass and the top.
I am bothered as well!
So my scoping, while not useful, was interesting. I may post pics later, but they're not very clear. (my phone in one hand taking a picture of the 2" screen on the scope in the other hand)
I can see the center hasp (when locked). It disappears when unlocked. I was thinking/kinda hoping the lock had hasps on the sides and maybe the right one wasn't moving enough for full movement. Not sure how I'd fix that, but at least then I'd know the problem. But as you say, there's just the center hasp, and that seems to be moving correctly.
There may something in the channel that may be blocking the glass on the right side? The picture are fuzzy, but here what I surmise (keeping in mind this is my first pinball machine, and I've only seen the inside of the back box though my little spy scope):
There are 2 long strips of wood attached to the top of box that form a channel between the strips and the front of the box. The glass sits in this channel. The 2 strips run from the edges of the box, with a gap in the center around lock & hasp. I was able to get my scope in the gap and angle towards the side, viewing down the channel.
It looks like there's something at the far end of the right channel. Like a brown slug on the back of the glass. Is it big enough and the right place to stop the glass from moving enough to be removed? No idea.
There's very little play in moving the glass back and forth. I do not think I could get something like a coat hanger wire up in front of the glass and hooked down the back.
I am going to try to slide paper up the front of the glass and hopefully then around to the back. If not clearing any obstruction, at least maybe I will see it form the side to get a better idea of scale.
