The other side will be a reasonable press fit, you might have to sand a bit off to get it to just start in. I epoxied both sides after final fit and alignment during the assembly making sure I had continuity between the tubes and center cap, so remove all ano at all connection, and make sure you align the battery cavities. You don’t need to use very much epoxy, so use it sparingly, don’t want to insulate the contact between the three.
When you cut the cap leave enough material to sand/file flat and square, a general idea of material removal marked in red on the center cap. Then remove a few threads from the right tube, leaving a couple to thread the cap on, I marked them on the pic with red to give a basic idea. Now you can epoxy the connector ring to the right tube, or wait and do it all together when your happy with the final fit, you only really need to just fill that o-ring band. Measure now from the inside, what you’ll need to remove from the left battery tube, shown by the green tape, it usually ends up with that o-ring band still intact, which is what you want, for your press fit and then you’ll pack that band with epoxy, before you press them together and align the battery cavities.
You only need to use enough epoxy to hold it all together in place, check to make sure you have a good connection, and battery tube alignment, then you can use a wood flat stick to pack the epoxy in heavy, just don’t go crazy with the stuff, then clear the battery tubes of excess epoxy with a round file.
If you need anything you can also PM me, take your time have fun (I really enjoyed it ) and good luck! :+1:
