You can use plumbing o-rings for smaller size shutters a lot of time. If you get a tight fit they hold really well. Ace Hardware or Mclendon's will have you covered on those.

If it's worth keeping get a retaining ring, if not get rid of it. L
One method of fixing a flat tire in the middle of nowhere.
Is stuff the tire with grass, hay, weeds, rags what you. Keep at it.
I have seen this done, it's hard work, but it saves the tire from total destruction and will get you down the dusty road. Remember this is middle of nowhere...
Flight of the Phoenix is one of my favorite movies. The first one, made in 1965.

I really like the snap ring idea.
just buy a retaining ring instead of a sloppy workaround.

Thanks but...this is a 'junk' lens for a specific application. I spent $10 for it and will use it for paper negatives with the shutter rigged to open as I press the cable release and close when I release the cable release plunger. Someday I spend around $200 and get a used 150mm something something that will operate within nominal limits. I'll make sure my $200 lens comes with a retaining ring.
And hey, this is a step up from a single element, series 6, +5 (200mm) close up lens that I'm using now and stopping down to f64 (1/8 inch hole).
epoxy it in if its a junker.
I agree. If it's a junk lens, improvise a junk lens board and epoxy it.
Easy way to epoxy it might be the putty type epoxy, mix and form a thin rope and wrap the threads, press it into the back of the lens board and let it set. Might even be removeable of the threads are wiped with vaseline before the procedure.
