Question(s) about pin-parts.

[Dazz]

Hey Guys,

I'm jumping on board the digital pinball fad and building a new pincab using a 42" LCD playfield.  I'm looking to buy my parts over the next couple days and I have a question about some parts.

I'm going to base my cab off of a Williams/Bally cab and would like to keep parts to that of Williams/Bally parts.

1.  Would anyone happen to have plans or dimensions for Williams/Bally cabinets?

2. What are the following components for and where would they go on a cab?  If anyone has pics of these on a cab and how they are used that would be very helpful.   

a. Williams/Bally Backglass Lift Channel
b. Williams/Bally Backglass Trim - Side
c. Williams/Bally Backglass Trim - Top
d. Williams/Bally Playfield Glass Rear Plastic Channel

3. How are leaf switches setup so the button hits them? 

I'm sure I have more questions, but I can't think of anymore right now... If I could get these answered that would be awesome.

Thanks in advance!

1: there was a few cabinets that where slightly different from the normal sizes... which cabinet are we talking about?...typically wide-body game, has a 25" wide cabinet/playfield, while the "standard have a 22 1/2" wide cabinet/playfield

2a: Item is the plastic trim along the bottom of the backbox artwork. it is a "U" shaped piece that protect the bottom of the glass from damage. it has a ledge on the front side for you to grasp and pull up and out to remove the glass.
2b: Item is the plastic trim along the left and right sides of the backbox artwork. they are "U" shaped pieces that protect the sides of the glass from damage. They are also slightly longer on one side of the "U" to help hold the artwork in place.
2c: Item is the plastic trim along the top of the backbox artwork. it is a "U" shaped piece that protect the top of the glass from damage. similar to item 2b, it is slightly longer on one side of the "U" to help hold the artwork in place.
2d: Item is the plastic trim along the top of the backbox itself. it is a "U" shaped piece that item 2c (ultimately the whole back glass/artwork piece) slots into to create a loose fitting, but secure once the bottom portion of the glass is in place.


3: which switches in particular are we talking about?? usually screwed down, it consists of two tounges of metal, separated by an insulator, which come into contact when pressed together, such as with a lever or button or bumper.  Leaf switches are used to detect a ball coming through a gate or going up a ramp. In older games leaf switches are used throughout most of the game, while newer games rely on microswitches, magnetic proximity (hall) sensors, and optos (optical sensors).
