Quick question. I was playing STTNG at my friend's house and his flippers seemed like they are too shallow when held up, so I find it difficult to cradle the ball. Is this correct? At rest, they are in line with the guides.
20150130_230243.jpgThe coil stops may not be the correct part.
If the "plug" on the coil stop is too long, this will happen.

Quoted from EEE:Wrong length plunger in there. Replace them both.
Quoted from ChrisHibler:The coil stops may not be the correct part.
If the "plug" on the coil stop is too long, this will happen.
I don't think this is true. I think he just needs to change the angle of the bats.
Without seeing them at rest it is hard to tell. But I would agree that the flippers are not coming up enough.
-Could be the flippers are set at the wrong angle at rest (not likely)
-The plungers could be too long and/or the coil stop could be too long.
Not uncommon with random rebuild kit being used to rebuild the flippers. Figure out the correct sizes for those two parts and measure what is on his STTNG. Put in the right ones or break out the saw and/or file and change the current ones to the correct size.
At rest, the flippers are in a straight line with the ball guides. I don't know how this game was designed so I didn't know if they were shallow or not.
There's one we pay locally that is set about the same, but that doesn't mean that it is correct.
Quoted from Anth:I don't think this is true. I think he just needs to change the angle of the bats.
You might not "guess" that this is true (vice "think"), but without a pic of the flippers at rest, or more info as the OP has now provided (that the flippers are in a straight line with the ball guides) we couldn't prove anything. Now that we know the flippers are adjusted correctly when at rest, the only remaining possibilities are incorrect coil stops or incorrect plungers.

The one resource that I have not been able to find is a good guide that gives the actual sizes for parts (like the correct length for a coil plunger). I can look up part numbers in the manuals, but that does not tell me very much. I will buy a kit that claims to be the right set of parts, but I don't really know. I can compare it to what is on the pin currently but there is no reason to think that is the right part either.
Is such a guide available for commonly available parts (plungers, coil stops, bushings, etc.)? I am guessing as spare parts dry up a list of substitutes would also be great or parts that would work as substitutes if a small change was done.
Quoted from mg81:Is such a guide available for commonly available parts (plungers, coil stops, bushings, etc.)?
Your guess is probably right on.
I'm unaware of any documentation on this other than the OEM manuals.
Sounds like a good thing to add to the PinWiki if you ever come up with one.

Here is a guide for Williams flipper parts:
http://www.pinballnews.com/learn/flippers/index.html
Per this guide, STTNG uses the longer coil stops. This means the flippers will not go up as high as games using the shorter stops. All plungers are the same length (per this guide and by my personal experience) so the only variable is coil stop length (or a bent bracket).
I have asked repeatedly what is the proper flipper stroke for the new vs old coil stops, but no one has ever had an answer to the question for me. I have read that the stroke with the old (short) coils stops is 2-3/8" from the flipper tip at rest to the flipper tip fully up and that agrees with measurements I have taken on my own games. With the long stops, as in my own STTNG, the flipper stroke is about 2-1/8" so you lose about 1/4" with long stops.
So it seems the OPs STTNG flippers are functioning as they were designed to function. You may not like that they don't go up farther and using the short coil stops would change that but it would clearly be a modification to the game away from the original design. Some will tell you that modification is unacceptable or cheating, but this is your game so make it work the way that makes you happy.

And just for fun, here's what happened tonight when a ball came screaming out of the right cannon VUK.
EDIT: Also, you should be able to make the Alpha ramp from a moving ball that's going down the left inlane, although it's not easy. Your flippers look just a bit too shallow to pull that off. I would adjust them up just a little. My flippers aren't just recently rebuilt but they have been since I bought it, so it should be pretty close to spec.
