I'd say just test it through game play, and give it a lot of play to get a feel for it and see how it's going before you adjust anything. That way you're only adjusting it if it's really necessary.

The catches come into play mainly for starting the T-REX modes. Hit the truck to complete the T-REX letters and it'll start a T-Rex mode, and the T-Rex modes start with the mouth coming down to catch the ball. First one is T-Rex multiball. Actual game play will give you the best idea on how well it's catching the ball.

I agree. The main thing is I just wanted to see it work once but wasn't sure how to make it happen. I won't start tweaking until I observe there is an issue, if there happens to be one.

Looks like you're ready for a pinball beach party (the covers remind me of themed beach towels)!

So, I've played a couple of games, and also played with the glass off, but for the life of me I couldn't get the T-Rex to even lower onto the ramp to catch the ball. I probably messed with this over an hour, and right when my frustration has reached is maximum it suddenly hit me . . . when I put my titan rings on the newton ball did I not put something back together. Topside looked good and I thought the bottom looked good until something clicked in my brain. Stupid me, I put the collar on upside down so it wasn't tripping the optos (the metal tab should rotate between the two sets, not above them).

Came downstairs to get an allen wrench, so headed back up to fix my mistake and hopefully feed the T-Rex!

Edit: Wow, so much more fun with a working T-Rex. He chowed down a few times, and even slung the ball once. I like this action even more than my previous DE JP T-Rex.

I love the covers. I see one of them has a tag so I assume they are sold somewhere. May I ask where you got them?

You took something apart there to install rings?

Yes, I removed the collar below the playfield and pulled out the jeep/rod assembly so that I could grip the newton ball well enough to remove the nut holding it on (I tried doing it installed, but I just couldn't grip it tight enough and didn't want to use a tool that might damage it). On the horizontal shaft there are 4 rings which I replaced (tough to see in pics as the shaft is directly below the Jeep).

Holy hell... You are way more dedicated to detail than me!

I just didn't want any black rubber degrading anywhere on my playfield. Also, OCD would not allow me to change out everything but those.

Here are the results if you don't follow the other thread (I didn't have pic at the time where the jeep rings were visible, so I've attached one): https://pinside.com/pinball/forum/topic/jurassic-park-stern-2019-owners-club-welcome-to-jurassic-park/page/160#post-5962762

Nice attention to detail!!! Clearly feeding the inner OCD daemons

Yeah TRex was such a unique and cool part of this game. I was going back and forth between this and Avengers, Keith Elwin games so far are awesome, and almost got Avengers because there was a company who's website claim to have this game but find out they did not and couldn't find it anywhere else, gave him a few days to see if he could get one on trade and low and behold another site just got 4 in IA week before last. So cancelled the order and snagged one of those up and couldn't be happier. Although I think Avengers may eventually get in my collection

Having difficulty consistently hitting the tower shot. In researching this, it looks like my upper flipper is slightly out of alignment (alignment hole should line up with front of plastic/flipper bat). Am I seeing this correctly?

Upper Flipper (resized).jpg

While the bats on Stern machines usually are intended to lineup with the play field indent alignment hole, one of the developers confirms the upper bat should be below. Much like in your picture...

Your set-up is correct.

Dot should be aligned with the top of the bat so that the ball hits the post on a non-flip of the upper flipper. Otherwise the ball will roll off and drain SDTM.

Your flipper maybe marginally back a little from the dot, however mine is much the same as yours.

What pitch do you have the PF? And is it level side-to-side? Lastly have you checked to see if the balll touches the tower ramp flap screw head, as if it does this will cause issues with making the ramp

One other thing to consider is the left screw on the ramp flap entering the tower. I’ve heard removing it (replace with Mylar) will vastly improve the shot. After having my game nearly a week, I’m starting to notice all the rejects from that shot and it does ‘seem’ like it in fact is because of that screw. I plan to remove mine soon - I would have done it already but don’t have the right type of screwdriver to get to it.

The 12 inch long kind!

I removed the ramp flap completely, no mylar, about 200 games and no wear.

I had to buy an 8-inch PH1 screwdriver from amazon for this one screw! It was a $7 tool for a one-time use.... but worked fine!

Be careful without any protection. Without the flap or any mylar protection, any failed attempts where the ball starts it's upward climb will land the ball smack down on the front of the ramp where it meets the playfield (where the flap would normally be), likely damaging the wood/clearcoat after awhile. The ball will be essentially dropping a few inches over and over from each failed attempt.

Cliffy has a new carbon fiber replacement flap that adheres to the surface and is made for the exact location.

I used a ratcheting right angle screwdriver. These come in handy for hard to reach places.

I had time to get the tool so since I noticed that Stern made a nice little cut-out above the screw for a long screwdriver, away I went!!! Your rachet may have worked good too as you had it in your toolbox already. All I had to do was remove one of the Tower roof triangles first. (I have since replaced the whole roof with a home-made thatched/bamboo version)

To remove the screw, I got the "uxcell #1 Phillips Screwdriver 8 Inch Round Shaft Non Slip Comfortable Handle" from amazon, now $8.79

During T-Rex Multi-ball the T-Rex doesn't release the ball until after the 2nd ball is drained. Then, it only releases it on a ball search.
For all other T-Rex functions, it works fine. Catches ball properly, registers properly, etc.

Any Ideas?

It's a screwdriver. I promise you'll find another use for it.

LOL

best yellow and black combined, not?

I have one of these but there isn't enough clearance between the bit and the side of the ratchet to turn the screw it hits the side of the ramp. Just my experience

Yellow & black combined would look good, I think. Would support a caution theme approach. Even so, personally I would still switch over to Titan silicone rings instead of rubber.

IMO Titans regular flipper silicone is way to bouncy, their low bounce ones are very similar to Super Bands. If going with Titans, and you have never tried the low bounce Titan flipper silicone, give 'em a try.

Most definitely. I have the thin flipper bands on all my pins.

Now that you mention that I may have used a small extension on the mini ratchet to get around that.

Quick question, what's wrong with actual rubber? It's actually getting harder to find real rubber rings. Everyone seems to have this silicone crap. From my experience, the silicone actually breaks faster.

My PF is at about 6.9 - 7.0 % and level side to side. I will check and see if the screw is impacting the ball flight. Thanks to all that reviewed and replied.

I finally have all Accessories for Jurassic Park in stock at 1 time.

I've had Titan silicone rings on pins for around 5 years with zero degradation. Ordinary rubber can degrade and leave residue. Not to mention all of the colors that silicone offers to personalize your pin.

However, I know there are traditionalist that prefer rubber for the "feel" and control. To each their own as far as I'm concerned - go with what you like/prefer.

If anyone in Canada is interested in a Stern JP shooter rod, Nitro has them back in stock:

https://nitropinball.com/collections/stern-shop/products/jurassic-park-led-shooter-rod

I purchased my JP premium, topper, shaker, and amber plunger from CGR. Was a great over experience overall, communication was great every step of the way, and I would highly recommend doing business with them.

Nothing. I tried titan, super band, etc... the bounce of factory rubbers seems the best for my liking. But, as someone mentioned, regular rubber leaves more residue. Not such an issue in a home use environment where you can clean your game at leisure. But for location or large collections, I imagine silicone would be better to help reduce maintenance.

See for yourself. Here is the one I just received from CGR: https://pinside.com/pinball/forum/topic/jurassic-park-stern-2019-owners-club-welcome-to-jurassic-park/page/162#post-5966179

Thanks for letting me get some plays in!

Game is legit. Great sound effects and choreography. Some shots are definitely on the tighter, more difficult side...which I actually liked. Made them more satisfying to hit. I really liked how many shots there are on this pin. Very cool.

Do you happen to have a link for the cliffy flap?

[email protected] is his email. Just tell him what you need and he will let you know cost and send you an invoice via PayPal.

Ball search isn’t going to find this magic spin ball. Bounced up from a hard pop bumper hit on the chaos shot and just spun there

Surely that shots gotta be worth some points??

The best I've done was the other day, I shot a very fast right loop and the ball got to the up post as it came up. The orbit trajectory combined with being launched into the air by the up post resulted in the ball being fired like a cannon at T-Rex - not sure whom was more caught off guard, me or dino!!

What is the angle of your playfield?

Yeah something is definitely wrong for that ball to sit on the wireform. Your playfield is flat or tilted backwards

It almost looks like the ball is magnetized. Can you repeat it by hand (try all 6 balls to see if one is the culprit)?
