Re: SAFETY <<< WAS: RE: [7x12MiniLathe] Mounting PVC Fitting for Boring
Lots of interesting ideas.? I'm particularly interested in working with heating the PVC for future projects.?? In this case, using the PVC coupling, once it was mounted and centered it literally took only 3-4 passes (on each side) with the boring tool in the lathe to zero in on the tapered fit I wanted.? The 90 degree fitting should progress in a similar manner once the mounting is solved.? Seems like that's the easiest solution. I like the idea of mounting the 90 to a block that I can put in my 4-jaw chuck - I have some aluminum blocks that I had originally planned to use as tool holders that should do nicely.

Re: Mounting PVC Fitting for Boring
开云体育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 :-) |
Re: Mounting PVC Fitting for Boring
开云体育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 ? ?

Re: Mounting PVC Fitting for Boring
Bull.... Overheating / burning it is a problem you want to avoid for more and bigger reasons than some fumes. 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. On Sun, Oct 27, 2024 at 9:06?AM WAM via <ajawam2=[email protected]> wrote: Careful when heating PVC... It gives off nasty fumes |

Re: Mounting PVC Fitting for Boring
开云体育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
mind that in this case the metal tube shall also be heated
otherwise it will be difficult to restrain a plastic tube being
cooled by the cold tube during the operation. I used these two methods a lot of times and it always worked. If the result isn't what you wanted, heat it again and it will almost recover its original shape :-) It also works well on nylon tubing. I purchased 3/8" tube for my
compressed air distribution and it happened to be 10mm. My
fittings were 3/8". Instead of wasting time with a new order, I
restrained the nylon tube using the second method. No leak @ 8
bars for at least12 years. On 27.10.24 02:38, mario mohl via

Re: Mounting PVC Fitting for Boring
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.

Re: Mounting PVC Fitting for Boring
Better still. Turn a wood dowel to the desired ID and use it to expand the PVC after slightly heating it On Sat, Oct 26, 2024 at 6:32?PM Mario Mohl <mario.mohl@...> wrote:

Re: Mounting PVC Fitting for Boring
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.
