Old playfield stripped

I'm realizing there's less parts I could use from the donor playfield than I realized.  I have completely new flipper assemblies which I'm glad I bought.  Old pinballs didn't have nearly the oomph, plus the mechs are probably pretty worn at this point.  I'm definitely re-using the trough assembly, doesn't seem like you can easily buy a new one even if you wanted to (at least not for cheap).  Going to re-use the sling mechs, but I'll be replacing the leaf switches.  Not going to have pop bumpers, and if I did I'd buy new ones.  Thought about salvaging the spinners, but they're usually a pain to work with.  I salvaged whatever screws that didn't have stripped heads, saved the dirty bands just so I have something temporary should I decide I need a wall.

I do have the flippers all assembled, in theory if I wanted to I could wire them up and start flipping, but it would be pretty senseless since there's no barriers.  At the very least I need to order the aluminum sheet to make the side walls.  I'd also like to figure out how I'm going to do the ball drain.  The trough I have actually fastens from underneath on the left, coming up to the top through a hole mounting to the top right.  I think to keep things simple (at least for now), I'm not going to have any ball save mode from the ship (like woz).  Once you drain, you get a chance to rack up some bonus points.  Eventually if I get some more channels, I may have a mode where if you hit so many targets, a door opens up that you can shoot into which launches the ball back onto the playfield.  I'd rather tackle that later so I don't get bogged down.
