Materials:

Wax paper
Tape
Epoxy
A penny


Tools:

pliers
exacto-knife


Take appart your turret, rip out the 4 small cylinders.



Take your penny, shove it into the gears, the top of the penny should be flush with the top of the center.



Get a smooth surface, tape down some wax paper.



Take a large amount of epoxy, dump it on the paper, and smash the turret on top.



Once the epoxy has hardened, scoar around the edges of the penny and remove it.

Drill out the holes in the epoxy.



Cut away the excess epoxy



Take a neoprene washer, cut off a small piece, glue on each part in the respective areas.



And your done, now you have a rear loading 1500 turret with a perfect seal and inter-changeable barrels.

The smaller piece of the neoprene washer makes the turret distribute the load of the spring more evenly stopping the turret from bending and ruining the seal, However you may need to spray some silicon lube in the turret as it becomes harder to rotate.

Great idea. I have very little experience with epoxy, what kind do you recommend?

[chefdave]

Just get either standard or plastic epoxy. Curing time doesn't really matter.

I'm trying out Metals Epoxy because thats all I have, I'll give you the results on how it performs after it cures...

That's cool, but unless I'm mistaken, the gear parts won't even come into contact with eachother.

Nevermind this, just looked over it again.

Disregard.

Alrighty, tried out the epoxy metals. It cured fine, but I'm still have rotation issues. It feels as if the two pieces aren't intertwining with eachother. So now I'm going to try another layer of 5 min JB WELD.

I had similar issues. Sand down the epoxy a tad, add some silicone lube. Also, don't shove the penny down into the rotation mech, just shove it down enough to hold in place. This will allow very little epoxy to get inside.

EDIT: Merz: Have you done Tantum's fix of the rotation mech? That should also help.

I have not, but I'll try the sanding after this stuff cures.

Yeah, that's why it's not working. If you look at the front half, the epoxy is at the same height as the upper rim, which is above the barrels. There is also the thickness of the epoxy to consider. Do tantum's fix and you should be in business. It isn't hard, only takes 15 minutes + drying time. To better comprehend what was happeing, I took a stock back half, and tried it with my epoxied front half. Gears did not meet.

EDIT: SOmething I did that I forgot to mention.... I filled the areas needed with epoxy first, and then slapped it down on the wax paper. That should make it less prone to caving in.

@ MSDFS, you have to make sure the outer rim of the turret is firmly touching the wax paper, so there is only a very small amount of epoxy over the rim. If you are still having problems, tantum's fix should work fine.

[mystefansdontflystraight]

I've already done Tantum's fix, so that's fine. Thank you very much for posting this, it has helped me a lot.
This makes rear-loading 1500s and 2ks a breeze. I will finish my 2k next.
