A review of Keller's Pro Justa Bridge

Hello everybody,

I finally received my Justa Bridge from Pool Dawg (great doing business with them by the way). I ordered one without really knowing if it's good or not, or if it would work with my jump cue. There is precious little information about it on the net apart from Larry Keller's own video and photos of the device on several online stores' websites. Since I got my hands on a Justa Bridge, I figured I'd post some pictures and videos of the thing, as well as my impressions.

Firstly, a small digression: I live in Europe, and there aren't many ways of getting a Justa Bridge here, other than ordering from the US. When my package arrived, the packing slip mentioned that the origin of the device is China. So, since "Made in USA" is written on the bridge, I suspect the parts were manufacturered in China and only assembled in the US. Not that it's a problem as far as quality is concerned though. Also, I'm not a very green-minded person, but a small device like this taking such a tortuous route to arrive from China to my home in old Europe seems wrong somehow...

Moving back to the thing itself: it is very light and looks quite flimsy, but it isn't. It is mostly made of hard plastic, held together with 12 (!) screws. The device is 120mm wide, 75mm high and 46mm thick, the shaft guide plates themselves being 7mm thick. The overall thickness of 46mm is the device's main disappointment: it just doesn't fit smartly in a cue case like a Moosehead bridge does. Even if you have oversized pockets, it'll make one huge hump in it, and if you bump your case against a wall, you'll likely damage the Justa Bridge. Not cool, but then, given how the device works it's unavoidable. Myself, I think I'll make a hard polystyrene box for it that'll strap onto my cue case. My Justa Bridge didn't come with any bag, box or user manual, but maybe Pool Dawg stripped away the packaging to lighten the box and lower shipping costs, I don't know.

The shaft guide slots are lined with hard white felt that looks like the dampening felt found inside pianos. The felt is sandwiched between plastic flanges, which explain the high number of screws to hold everything together. The upper edges of the felt look like they don't need much of an excuse to come off though. Other than that problem, the felt lining is great to guide a cue shaft while protecting it.

The Justa Bridge attaches to the end of a cue shaft by means of a rubber ring, tightened by an outer sliding cone. It's the same principle as bit holders on milling machines. It's a super quick and secure attachment method, but the problem, as with milling machines, is that the range of shaft diameters it can accept is rather limited: open, the rubber ring is 13.2mm in diameter. Closed tight, it is 12.3mm. Therefore, it'll only accept "standard" 1/2" pool cue shafts, between 12.5 and 13mm in diameter. Oversized 14mm jump or break cue shafts won't go in (without enlarging the rubber ring), and undersized shaft won't fit tightly, if at all. Look at the videos below to see the device fitting great onto my Eliminator pool jump/break cue shaft, and not at all on my Chevillote carom cue shaft.

The twist-to-raise magic happens thanks to a plastic spiral cam that turns along with the cue shaft holder and drives a pin on the upper shaft guide plate. On my brand new device, everything is nice and tight, and twisting the cue takes some effort despite three teflon washers. Not enough effort to unscrew a two-piece cue, but enough to flip the Justa Bridge on its side if you don't have a cue's weight in one of the guide slots. Annoying, but I think the mechanism will loosen up over time. If not, it's easy enough to loosen the axis screw a little I suppose.

Also, be aware that the device doesn't quite hold its position on its own if you let go of the bridge cue, especially with the main cue in the furthermost guide and you push down on it. This is why you see Larry Keller playing while holding his bridge cue's shaft in his video. It's not a problem though if you already leave a hand on the bridge cue when you play, as you should. It's very easy to get used to the Justa Bridge's extra degree of liberty, and you quickly forget that you have to hold the playing height.

As far as playing is concerned, I confirm Keller's jumping of the cueball from the middle of the table isn't fake: I did it first time out, and it's very efficient and comfortable. For regular play, I found myself getting used to the Justa Bridge very quickly: raising an lowering the cue tip immediately becomes second nature, and it becomes addictive too. Going back to a regular bridge, I felt something missing. The main trap to avoid with the Justa Bridge is to play like you would with a hand bridge: it's easy to feel too confident and lower your cue too much to draw for instance. But no matter how good a mechanical bridge may be, it's only a mechanical bridge, it's not as good as a hand bridge, so chances are you'll miscue. I had to remind myself to go easy on draws, follows and english with the Justa Bridge.

So, to sum up, here are the pros and cons of Keller's Pro Justa Bridge:

Pros:

- Innovative,
- Well built,
- Guides the shaft great and protects its finish,
- Quick to install at the end of a cue,
- Doesn't pull on the cue's tip when you remove it,
- Intuitive and easy to get used to,
- Affords many stable cue positions,
- A great conversation starter,
- Relatively cheap, value for money (your opinion may differ on that one. We in Europe are used to paying through the nose for everything...)

Cons:

- The edges of the felt look fragile,
- Too bulky to be truly portable,
- Addictive (if you lose it, going back to a regular bridge may be a bit disappointing),
- Only accepts shaft diameters close to 1/2" in diameter,
- Light "plasticky" feel. I believe it is solid, but it's not very convincing at first sight.

Finally, some photos and videos of the Justa Bridge. Sorry for the poor quality, I shot them with a very old digital photo camera:

I've had one since they first came out... even have one that is powdercoated, before they were plastic. It's a great tool. I carry it in my soft case and is one of the reasons I like a soft case, another is the Tony Ryan cue extension.
 
Nice review! I just ordered one for a friend, but played around with it for a little bit. It's certainly well thought out and well designed. If you are planning on using it on a thin shaft though, it is an issue. Not sure if you can wrap something around the shaft to get it to hold. Oh, and as far as the packaging goes, there is none. I ordered from PoolDawg too and it just came with a loose plastic bag. I'm thinking about getting one of these for myself now!
 
I also own one of these. When I was in Vegas a couple of years ago Diamond products had these in their booth with different colored felts. Since I had only seen the white felt I did ask them where a person could buy a different color. They advised the only option was to remove the existing felt and dye it. I did so with Indian Black dye. Mine actually came out more blue than black. I suppose a good food coloring might work as well. You have to be careful because the felt does swell from the moisture. It wasn't a real problem but it did mean having some problems with the holes lining up.

The felt is supposed to be replaceable. Unfortunately I can't find a source anymore.....:frown::frown::frown:

It is a great bridge that offers so much flexibility as the different videos I've seen. NOTE: the BCAPL website used to have a terrific video demoing the bridge but it has since been pulled down.

Here is another link of it in use..... http://www.youtube.com/watch?v=RfwVNK8p8as

Thanks for the review. I also have one of these and use it quite a bit. I have never heard of using it for jumping in the middle of the table before though. I am going to have to try that.
 
This device is extremely innovative! Are any prominent pros using it?

I'd have to think if ... for example ... Archer whipped one out for a couple shots during the Mosconi Cup, that'd probably provide quite the buzz!

I know I'm not quite on his level, but if the owner sends me one and $10,000 I will not only use it, but I'll even tell people where they can get one. I know, I know... I'm just that kinda guy. :wink:
 
Coincidence

:groucho:A week ago I bot my second one. I ordered one for a buddy. Both are the hard plastic. I bot the first one about 6-7 years ago. They will loosen up (too much) over time-then you have to tighten it back up.

I didn't buy replacement felt first time around. I was I had. I think I bot it direct from Keller out of Sonora, CA. If memory serves- I think original R&D units were aluminum and came in different powder coat colors. If anybody comes up with replacement felts-let me know please.

It's a cool bridge -works well. It was used in some prominent Tournaments several years ago and got some good exposure. A little pricey-but not out of line considering the protection the felt provides to shaft-especially if you're cranking up the speed for a bridge shot (hate that shaft grindage from some plastic bridges).

I find that in storing it in the side pouch of my case-I can zip up to the protruding collet but not over it. Works OK for me that way.

It's like being a Bass fisherman-you got to buy all the cool stuff

I don't think it's a must have-but a useful tool.

PS: great photos

You got me all figured out here :) I love gadgets, and I ordered the Justa Bridge because it looked like a cool gadget. I like it, and its flexibility grows on me, but I could well do without it. Heck, I don't even use the bridge all that much... But I'm not sure I could do without the coolness factor it gives me at the club :grin:
 
love it

That is one of the best gadgets I have found .I like that it will not dent
,ding or scratch a cue
 
I've sold a few over the last few years. Most buyers liked it and it held up well. My only complaint is that when the cue slides over the felt, there is too much resistance and I feel like I have to "push" it through the felt. Also, the felt does get blued by the shaft going over it. I love to use the upright position to shoot over balls!

I would like to buy one and I figured the logical place to buy it would be AZ Billiards but I couldn't find it on their site.

That is one thing I like about the Justa Bridge. I play most of my shot with a fairly tight closed bridge (hand bridge that is), with a glove. The Justa Bridge feels quite similar. I don't care much for the excessive glide and the atrocious wood-on-something-that-dings-wood noise provided by most mechanical bridges.
 
I think I am sold on this, I play one pocket and sometimes your jacked up or shooting with the rest so it might be best to have something like this. :smile:
 
Here's a quick update after using the Pro Justa Bridge for a few weeks:

- A friend of mine found a way to dislodge the pin from its spiral plastic race. All it takes is forcing the bridge to turn using the cue guide plates while it is at full extension. A little creative bending fixes it in no time however, so no harm done.

- I found cue cases that have pockets big enough and rigid enough to hold and protect a Justa bridge: the Buffalo Pro Bag line. For some reason, I can only find this site that shows some of them. There are other colors and materials than dayglo-colored plastic though: mine is tan (probably fake) leather. The front pocket in these cases is just about the right size for the Justa Bridge, about as deep as the cue driving mechanism is high, and semi-rigid to protect the content. With the Justa bridge inside the pocket, there's still plenty of spaces for a lot of additional small accesories. These are cheap cases too.

- At the table, I now can't do without it. I reckon the best part of this bridge isn't so much the up-and-down action as the quick release system. *Click* it's on your spare cue, *click* it's off, and there is no risk to the tip. A classsic moosehead bridge just can't compete with that.
 
i don't own or use this bridge.....but I may buy one. I noticed a number of people asking about felt.....aside from it being available in any good fabric store.....consider using the felt pads that come in those inexpensive eyeglass repair kits....I lost a screw from my glasses the other day and had to buy a kit.....I think it had about 3 pair of those little white felt stick on thingys......Dan
 
Thanks but, nose pad thingys-won't work

The fabrice store might have this heavy felt. You'd need to make a pattern from the old one and cut carefully. The felt seems to be in one piece with the 'fingers' cut out as part of the pattern. The felt is clamped in place by the two outer ridgid bridge sides via a series of screws.

It would have been a lot easier to buy the replacement felt when I bot the bridge 5-7 years ago. I figured I'd buy em later. Later is now. Now I can't find em. Sounds about right.

Anybody know where the felt replacement can be purchased?
 
I haven't opened the flanges, but I think the felt is in one piece. Provided you can get your hands of a piece of felt with the right thickness, it should be easy to cut the openings with a pair of scissors or an exacto knife. Either that or replace the felt with balsa wood, or some other soft wood that might be stronger than balsa.
