So, for those who have no common sense and who are so scared :
please don't use nor drink water, whose scientific names are also
di-hydrogen monoxide and mono-oxygen di-hydride.
It is well known as being very dangerous. Among the risks are : an
excess can cause landslides, it dissolves rocks, perforates stone
and metals, and also clouds the pastis. Drinking too much of it can
lead to an edema.
That said, whatever the liquid, gas, or material is, always wear
googles, use gloves put a breathing mask and avoid breathing the
vapors or fumes. I assume that any adult would know this but, you're
right, a reminder may be useful.
In addition, don't cross the streets. Finally lots of people die in
their bed. A word of advice: don't go to bed. Keep sitting instead
:-)

HCL?? Reads article… yup, HCL. ? Yeah, don’t heat up PVC so much where it goes past being all gooey, it releases chlorine (nasty stuff) that combines with water in the air to create hydrochloric acid.? Now breathing that isn’t too good for your lungs, but even worse it’ll make your lathe & other tools go rusty really quickly.? That’ll really upset you. ? Like most plastics PVC will start going soft at about 100C (boiling water temperatures), well below the stage where it’ll start outgassing and causing trouble. ? It’ll be fine. ? I once tried laser cutting polycarbonate.? It didn’t work, emitted a nasty looking yellow-brown smoke and made things go rusty, not recommended.? Yep, chlorine & HCL. ? Tony ? ?

Heat it by immersion in boiling water.
Ventilation is also welcome, always, for many reasons as well.
So yeah, don't lock yourself up in an airtight room to burn some PVC. That would be just as stupid as it sounds.
Be sensible, the rest is fearmongering.

I can confirm that Mario's method is an excellent one.
In addition, if you want to restrain the diameter, use a glass
jar into you push the elbow in after hot air heating it. Don't use
a flame, it may damage the PVC and/or give a poor result. You also
may turn a piece of metal tube at the required dimension. Keep in

restrained the nylon tube using the second method. No leak @ 8

In the coupling I bored the diameter out about 0.08" at the opening and tapered it about 1/2 degree as the bore extended into the fitting.? The vacuum fitting and the saw fitting required slightly different diameters.? That gave me a nice press-on fit.

Visit a local auto parts store; they'll probably loan you an exhaust pipe expanding tool that'll do the job.

I made the bore with a slight (about 1/2 degree) taper which gave a nice press-on fit for both the vacuum fitting and the saw fitting.? Couldn't do that on drill press or with hole saw (I don't think).

I'd probably do it on the drill press, but to keep it a lathe project, you could mount the elbow on the carriage & use a boring head or suitable hole saw chucked in the spindle.
