So I am trying to figure out the best way to get the manual rotation mechanism installed. (The manual rotation mechanism is that piece that connects to the turret rod that "clicks" the rotation in place.) How do I get this thing to stay fixed though?

I see one example in the AT3K overhaul thread:



He used a piece of PVC pipe and glued the rotation mechanism onto it.

Has anyone else looked into an alternative method? I find it rather haphazard to use a random chunk of PVC pipe.

I rotated it around so it was wedged under the orange L shaped thing the hose attaches to. Only works with stock rotation spring though, anything stronger and it comes out.

EDIT: It appears as if the protruding piece of the mechanism actually rests against where the plastic that the firing pin comes out of on tank. Not sure this is ideal but it works. (pic below)

If you do your overhaul right, you don't need anything to hold the turret in place. the seal between your tank and turret should be tight enough that the friction holds the turret in place. AT least thats the way mine works, I simply gutted everything off the tank and stacked foam until the friction held the turret in place after rotating, then I coated the foam in goop to make smoother and prevent ripping, and added grease. If you need i can add pictures.

So your turret doesnt index?

To keep the rotation mech from spinning in circles and not actually doing it's job, I cut a small strip of polycarbonate. I drilled and tapped new holes attaching the piece of polycarbonate to a piece on an existing piece of the gun. This keep the top piece from moving freely and allows the rotation mech to do it's job. Make sure you line up the rotation mech with your barrels.

There's your answer. You can do this other ways also.

No It does not, But it's not really that hard to line it up.

Just rotate it as close to the shell as you can and hot glue the shit out of it.

Here is how mine looks:


The orange conduit glued in in the background was originally meant to hold the mechanism, but its not actually doing anything at the moment.

It's not that hard to make it indexing which is far better than having to look and line it up each shot.

What happens if you fuck the seal up or something and you have to remove the turret? Would be a pain in the ass.

Yeah. I read that, but I was wondering if anyone else came up with something.

Whoa whoa whoa. Hold on. How does this even operate? Assuming "front" refers to the front portion of the gun, if the front piece of the rotation mechanism is flush against the tank, then that means the rear piece is what is being pushed against when the gun rotates. But if this rear piece is glued to the orange tube, wouldn't it mean that your gun cannot rotate? @_@

EDIT: OH. I think I get it. Looking at mine, it seems the metal part can simply be wedged against the plastic bit that joins the tubing with the tank (this is the stock gun; the overhauled AT3K picture replaced the vinyl tubing). This way, the rear piece can freely move forward and backward but not clockwise.

I wouldn't suggest that.
If you don't align the rotation mech correctly, your rotation will be off and the barrels may not correctly align with the tank.
I will try to post pics of mine later, but what I basically did was cut a piece of cpvc to size and hot glued it to the shell of the 3k so that the metal pin rests on it.

The bit I've circled goes underneath the firing pin on mine.

The only reason there is another scrap of pvc glued to the side of mine was because I cut my cpvc too much.
It looks ugly from the inside, but its barely noticeable from the outside.

Okay. Thanks for everyone's input. This is what I ended up doing:

I first noted that three objectives must be achieved:

1) The forward piece must be moving and the rear piece fixed.
2) The rear piece must align with the barrels.
3) The rear piece must be fixed in a way that permits removal of the barrel.

So I decided to glue the rear piece to the plastic portion of the air tank that the firing pin feeds into.

I first filed down the diagonal slant and the "bottom" of the rotation piece, like so:


Here is a picture of it before, for comparison (sorry for the bad quality):


Here is where I glued it (view from the loading side and the shell side):



I will probably sandwich a piece of plastic or hot glue in between to add more stability.

And yes, the turret is not present. Rest assured though, upside down is just as good as right side up (see for yourself though).

And here is what it looks like installed inside the gun:
