I'be tried taping it up, but it will be a nightmare to undo and redo for repairs or modifications.

Rowland, I agree it is a task to undo and redo, I typically just put a new bag on if I had had to remove it for any reason. Re your pressure test, I don't agree that's a good way to test, as it will normally sit at atmo pressure and not be subject to pressure stress - it's there as a simple barrier to keep the gas contained (not a pressure vessel). Heck even a normal drinking glass will contain argon as it is to heavy to move upward against gravity - unless there is a breeze to disturb the surface and blow it out. My long imaging run test did not produce any condensation or fogging inside the bag (or the adaptor tube) and the images were great, which tells me the argon is doing its job. But yes it can be a pain to setup.
