I'm using the standard schedule 40 PVC piping to construct railings for a platform. No water (or any other fluid) will flow through the pipes but I need to disassemble the railings for storage, hence no gluing (but the same question would apply even if there was). Connection will be secured by drilling a hole through the fitting and pipe and putting in a bolt and nut.
The problem is that the fittings are an interference (or worse) fit on the pipe and short of cutting about 1/64" off the inside of the fitting or the outside of the pipe end I can't get the pipe to bottom out in the fitting. Up to now I've laboriously used a belt sander to grind back the last inch or so of the pipe (just chamfering the end doesn't help) but there must be a better way!
I remember many years earlier having the same problem with 4-inch sewer line (the current pipe is 1 1/4") and there I was running water (and other things) in it. The sewer line didn't leak but I doubt any pipe was bottomed into its fitting.
So what's the secret?
