Ok here we go.
I have photos of the screw from the game next to the one Bally/Williams used on all their games.
And a photo with it installed.
Here are the results.
Is it better then the rounded top with ball clearance?
Yes, but just slightly.
No matter how tight you screw it down it will only go so far because no counter sink.
The ball still clips it but just barely.
However you have to put it so tight that it causes the ramp flap to pop up a bit on the other end.
I have now gone back to original screw.
This hole really screams for a counter sunk hole but we have no choice but to play the cards we were delt.

I've tried a very similar screw and it didn't work (since the screw requires clearance on the PF).

A pancake head screw is flat where it meets the surface its being screwed into and would make a better choice although it may still be a bit too high but better.

Agree.
That is the only type I had on hand to test out.

Yours looks like a counter sink flat head to me.

Ah yes, duh.
I was on the sauce and confused it with SC.
Thanks

Hey folks,

I have a wonky spinner on one of my JP's (first photo). I've owned quite a few games over the years and have never dealt with this.

I checked the manual, and this mech isn't listed.

Question: Any experience with getting the wireform adjusted properly? I tried fiddling, and nothing was working.

Thanks for any advice!

Just push the spinner wire through to the next bend, your on the outer one which is causing the gate to lift

Man do I love invalid frenzy. Such a fun multiball!

It also looks like you need to straighten up the main spinner bracket. You can easily see someone has bowed it down in the middle...which has cause the main support on each side (where each hole is for the spinner wire goes through) is spread out to far from each other.

Thanks for the responses. I could see both the of the things you guys are pointing out...my problem has been pushing the spinner wire through to the next bend hasn't worked despite much fiddling. I guess I need to take the mech off entirely to fix it up...hopefully it's not that big a deal to remove.

Aside from the warping, it looks like the leaf switch is on the wrong side of the spinner arm. The arm on the spinner should be above the leaf switch and pushes it down while spinning. Maybe I'm wrong but it looks that way from you pics.

Understood...that's what finally alerted me to fix it...since the right prong wasn't covering the switch properly, the switch would wiggle out of it's correct location.

Once the spinner mech was taken off the PF (which was a minor PITA), fixing it was trivial. Whoever fiddled with this most likely tried to adjust it without removing it (which led to it failing). Who knows...

Works great now

I’ve got a fever and the only prescription is more goat!

I made another easy but IMO important tweak, I bent the wire ball guide in a bit at the control room lane, now the ball rattles less and hits the target more often. This along with repositioning the ball guide by upper flipper on the Helicopter ramp has a made a marked improvement in shot completions.

Help please. This weekend I installed a set of pinstadiums and additional trough lighting. Just realized that now whenever I hold down both flippers, the lower right GI turns off. This is the same place where I have the trough lighting tied into. My guess is that somehow I am overloading the circuit, but this being my first pin, I’m unsure (other than removing these mods) how to fix it. I also notice the flippers will now sporadically loose power during my game. Any suggestions how I can troubleshoot this? Has anyone experienced something like this before?

put in a real amber for the amber shot drilled a small hole underneath and tyed it into the amber light

EaglePin I'm curious, did you actually check with someone on the Stern design team? Keith?

Ever since Insanity_Falls mentioned this, I'm more annoyed by it.

Ok it is still happening. I de-installed the pinstadiums and the trough LEDs. When I power on the game the lower right GI (under the right sling)will turn on maybe 25% of the time. Now when I start a new game, the lower right GI is turning off. Is this indicative of a loose connection somewhere, or did I mess something up during the install of the mods? Thanks for any suggestions.

Thanks. I think you are onto something. I raised the playfield and did a GI test one of the times that the lower right GI was working. I noticed that there are 2 bulbs under the plastic between the inlanes and outlanes that were flickering due to what I guess is a loose connection. I was able to work my fingers in there and just touching them made the flickering stop. Certainly seems connected to this issue because now double flipping isn't causing the GI to turn off. Unfortunately these bulb sockets are directly under the flipper assemblies. Will I need to disassemble those to tighten these bulb connections?

Thanks again. This is the first issue I have had with the game. Glad to know the community has my back

Ever since busterfriendly mentioned this, I'm more annoyed by it.

I’d like to look at buster’s picture. Can you tell me which page it’s on?

Sorry, when I said by design I meant mine arrived that way so that's the way it came from the factory on mine. I have no idea if they're assembling it the way Keith intended.

Glad you got it working! I imagine getting to the screws to take it off was really tricky if you don't have one of those bendable screwdriver attachments!

This quarantine is great for my JP scores...

I have a question about the sound on this game. I’ve noticed a faint buzz or distortion in the mix in a few places. The one that is the most distracting is the “horns section” that plays as the main music during play accompanied by drums, after the JP theme. I’ve also noticed Nedrys call outs during attract mode sound super hollow or in a tunnel or something. Have I maybe messed with some settings? Anyone else notice either of these? I’m on code 1.00

Anyone else having an issue with the auto-launch not being able to get the ball up the reverse ramp?

Did you just adjust that in settings?

Is the general consensus with JP to go premium? Both seem like fabulous games, but that moving TRex is super cool. I'm turning 30 next month and heavily considering pulling the trigger on a NIB Prem as a bday gift while they're still in stock (at some places). Probably not the smartest move during a pandemic, but meh.

General consensus is to go with the Prem; however, I have a Prem, and could live with a Pro here; the layout is identical; and that's really the draw of the game. Given the pandemic, maybe go Pro with a shaker and save some $$

This is really interesting. I'm also talking to a friend who owns a premium and he's recommending the pro... I was not expecting that.

Raptor pit and moving T-Rex are worth it I think. But, if you can only afford a pro you can't go wrong there either.

Premium here, can’t imagine the game without the T-Rex grabbing the ball. Never had a problem with the T-Rex. Launch ramp on the other hand...still getting that one to work smooth.

If the pro would allow you to skip the T-Rex multi-ball annimation then I'd say Pro all day long... but since it holds the ball for what I suspect is as long as it takes for the dinosaur to eat the ball and throw it back you aren't missing much flow by going premium. Maybe there is a setting I can disable to turn off the up-post at the start T-Tex multi-ball.

Much like the sarcophagus in IMDN on the premium, it was fun for the first little while of ownership but now I wish it would just put the ball back in play so I could keep playing. Quit holding on to my balls!

Have you tried hitting both flippers while it's holding the ball? On my premium any time a ball is being held by a post all I have to do is hit both flippers to have it released early.

That is interesting...I have the premium... and I've had to do A LOT of tweaking on my T-Rex...and I would still recommend the premium. It's a pretty sweet feature when it's working. Plus I think the raptor gate and helicopter blades are pretty cool.

So the heli blades I'm completely indifferent about. Do they actually do anything in terms of gameplay? I do think the raptor cage turning into a bash toy is pretty neat though. I've played both the pro and prem and had a blast with both so I don't think either is a bad move for me. I certainly wasn't expecting a premium owner to recommend the pro though.

Loving the premium.

The T-Rex adds a whole extra level of interaction...now is worth the extra cash? I thought the moving T-Rex was and is worth it so I went with the premium. The Raptor gate is also pretty fun to lock your ball and bash it. The pro is a great game no doubt, but if you can add a little extra spice to a great game then it’s just more of a complete package.

decided on a purchasing a pro today. i was considering the premium but money is money and i haven't had a 3 flipper stern since sharkeys shootout. looking forward to a non typical shooter layout from stern this time around.

Works for the paddock selection, kind of, I'd like it to kill the post altogether before the ball get's to the post... but on T-Rex all the mashing of both buttons won't kill that animation or get the post down.

This is one of the greatest games of all time, just like Newman saids "dont go cheap on me" I would go LE/Premium all day long, I couldn't imagine owning a pro version of this game. The T-rex alone is worth the extra money, plus I love the sound of the helicopter blades as they spin.

Just ordered a Pro. I should be a member of this club tomorrow or Friday! Super pumped here.

My premium, built 3/20/20, had a spinner that wasn't registering. I bent the spinner wire to get it to push further on the switch leaf, but no luck. I could have bent it more, but didn't want to mess up a smooth spin.

I Took it out and bent the leaf. Works great now. I probably could have done this without removing the switch, but removing it wasn't too bad, and allowed for precision bending. This technique also filled up some unemployment time. There was no screw that could be adjusted as mentioned in post 3324. Loving the spitter sound effect now!

I had to tweak my TRex a little - adjusted center - adjusted height (loosen mech from behind) - and did the tape trick on the ramp before the revised part became available. Since dialing it in, I haven’t touched it once.

The TRex is one of the best mechs/toys/features in pinball I’ve ever seen. I’ve played a pro and they play fine but that TRex.... it’s a must have imo.
