Hi all!

Been thinking about this and researching on and off for quite some time. It was always a far away future thing. Now, however, I see a candy cab in my not-to-distant future. Space for two isn't really feasible, but one is!

So now I'm wondering if anyone knows of anyone adding a rotation mech to something like an Astro, a Blast, or even a NNC. I know it wouldn't necessarily be simple, but think of the potential benefit! I have a buddy who is a metal worker, so crafting something from scratch could be possible... But... How!?

I can't be the only one who would love to make this work, right?

Ideas!?

I'd also thought about this, since I have a NNC and play fighting games with my friends but shmups by myself. My first thought would be modeling it after the Egret rotation mech but not sure how that'd work.
 
Hi, I've never seen the rotation mechanism of the egret in person, but here is some info about it:
EGRET II
And some images:

I think this mechanism is very dificult to port to NNC like cabinets because doesn't have the front door open mechanism.

For a NNC I have a couple of ideas, but I think all of this must be like a removable tooling or aid joke to make one person able to rotate itself without too much effort, but removing the front panel and screw the monitor cover in the new position will be mandatory.

At the moment I'm just continue to restore my NUC, but can be fun this thread to discuss the posible options!
 
I took mine apart to repair it, I would say the toughest parts to duplicate would be the corner pieces, the pieces that attach to the monitor from the wheel, and the plate.
 
The biggest issue es room for rotation. It works on the Egret because you can move the monitor surroundings out of the way. Once had a woody where you could pull the monitor towards you and then rotate which also eliminated the space issue for rotation. On that cab, the bezel was rotating with the monitor.
You can see it here: https://www.flipper-stern.fr/borne-...ard-borne-arcade-wdk-eurogames-multijeux.html
 
Some great ideas in this thread already!
Has anyone here actually done a diy of this on a candy? From how it looks, I really agree with the above comment that "it's not that complicated .... but its not easy either!"

I bet if someone came up with a kit that fit some common cabs, say an Astro or a Blast, they'd sell swiftly.
 
I've not seen it done on a real candy before, but I have seen someone make a rotation mech using a big ass bearing from a lazy susan on a DIY sit down cab.

It might be possible to make a mech for the Astro since the top cover removes easily and gives a ton of clearance, but probably not with a Blast given how tight the clearances are, and how much of a PITA it would be to actually take apart.

I'm not sure how useful it would be at the end of the day. You would still need to take the cab apart, and by the time you went through the trouble you may as well manually move the monitor anyways. The simplest solution is still having a dedicated tate cab if floorspace allows, and from my own experience and watching plenty of others, cab ownership rarely ends at just one anyways.
 
I'd welcome a rotation mech even with cabs like the NNC that require you to remove the front panel simply because those tubes are bulky - it's difficult to rotate one by yourself currently without scraped knuckles and/or banging the tube on the edges of the opening.

One factor to take into account with an after-market rotation mech is the chassis PCB. On the Egret, the chassis mounts separately from the tube, and you have to be careful not to snag the B+ wire when rotating the tube. On the other cabs I've seen, the chassis PCB is mounted on a tray that's part of the tube frame and rotates along with it.

The problem with those lazy susan designs is they would never work on a 29" monitor.

The utility even when taking things apart is not having to lift a heavy monitor, maybe even by yourself, to re-mount it. I hear what you're saying WRT multiple cab ownership, but I do suspect if there was a kit or even plans to make this actually happen, it would be appreciated and utilized by MANY!
 
There should be plenty of clearance to do this on an Astro/New Astro. Blast is unlikely since the monitor is recessed into the cabinet body. I forget what a Naomi/Net City looks like but it might be possible.

I've been planning to make something like this for a while now but life has gotten in the way.

Great points! Btw, long time no see. Hope you're well. 😁

Preach! 😂

Life always does that!

I think you mean 27" (29" is the overall size of the tube, and not a standard measurement outside of Japan).

The original design posted used a considerably larger CRT (32" viewable), so I don't see how it wouldn't work with a 27 incher if clearance isn't an issue (which very much might be the case since it's a giant ring around the monitor). Regardless, that wasn't so much of an example to follow more than it was a curious memory from me that popped up when I saw the thread topic.
 
Ideally, the rotation mechanism on a cab without rotation clearance would allow the tube to "pull forward" in some manner, rotate and then "push back". I'm thinking something like the telescope mechanism on a steering wheel of a car, or a swing-out mount on a flat panel TV.

For example in NAOMI/NNC cabs first you have to unscrew the front panel and the monitor bezel, then rotate the monitor.

I think the hardest part is to think about a jig (to support all the monitor weight) while you are rotating the monitor, I don't think an automatich mechanism would be possible without modifing to much the original structure of the cab .
