1958 united 3 way shuffle alley, and general questions

hi,
i'm working on my first shuffle alley, a 1958 united 3-WAY . first
question: the replacement rebound rubber( from pbr) has a narrow
channel in the back, its not solid rubber. the one i removed is the
same way, but has hard a hard piece of rubber slid into the channel.
its looks like it belongs there, does it? do you have the alley
level, or pitch it toward you to aid in the return of the puck. makes
sense to pitch it a little , but if so , how much?

also, every part in the game has an ID sticker, but the big relay
bank. can anyone ID the relays ?there are 16, i think . tripping some
by hand raises pins, but it would help to know which relay should do
what. i have some paperwork, but nothing on the relay bank. i think my
pin trouble is there.

thanks much
 
I replaced the rebound rubber on mine and had zero difference on the rebound. You need to "slick up" the formica. You could polish it with the various products or the easy way is 100% silicone spray. Search for it on here, that's where I got the info, works like a charm!
 
the rebound rubbers i have used were brown in color and had no pitch to them. They mounted flat and were screwed on by thin metal rails and then bolted to the game with larger bolts and washers. When the rebound rubber gets old and hard, they lose the nice bounce needed to send the puck back to the players. I always used a good paste wax on the playfield and with the powdered shuffle alley wax used to play the game, I had no issues with the puck able to travel back to the throw line. As far as the big bank of switches, its been along time since I have seen one with the labels , but you are right, some were the pins, shot relays and such. I don't have one I can send you the information with.
 
Installed my new rebound rubber on the Midway Cobra and it had no pitch. I cleaned the formica surface with Novus 2 to pull out all the dirt, then used Meguire's Carnuba, sprayed a good amount of silicone, then Sun-Glo 5. Silcone holds the Sun Glo in place for a while longer than without.

If the rubber was installed with a pitch I would think that it would create a downward force on the puck rebound and slow it down more vs. outward...

Regarding the relays I'm the odd man out with the Midway Cobra and have never worked on a United.
