Mounting PVC Fitting for Boring

 

I've got a 70's era radial arm saw with a dust collection port that doesn't match current vacuum fittings.  I bored one end of a 1 1/4" PVC coupling to fit the saw outlet and the other end to fit the vacuum hose.  It works, but for long term a 90-degree fitting would be much better.
 
I have a 1 1/4" PVC 90 that I would like to bore out to do the job.  However, having trouble figuring out how to mount on my 3" 4-jaw chuck (see photo).  I need to mount so the opening(s) is centered on the spindle so the 4-jaw adjustment capability would be great if I could get it mounted.
 
Any ideas on how to mount?

Turn the jaws around first . Then I would drill a hole through the 90 centers with one of the openings & run a piece of all thread or a long bolt through the spindle with a washer & a nut on each end I think that the jaws would just keep the 90 from moving , not sure ya will be able to get much clamp pressure that's why I suggest the bolt/allthread . Ya don't need much speed to get this done . Ya could also  cut one side of the 90 off & glue the original bored part to the 90 with PVC cement .

Hi Mike. Personally I would take the easy route and use short pieces of plastic pipe bored etc to suit and connect all together.

One piece to fit dust collection port, other end to fit 90deg fitting, then the next piece from the fitting, other end to suit the vacuum hose.

As short as possible, shouldn’t take up too much extra room.

That would work.  I could use 1 1/2" pipe and have almost the full length buried in the 1 1/2" 90 degree fitting.

It sounded like he wanted to use his lathe , thats why i piped in with my idea .

You are correct.  However, I will still be able to use my lathe.  The 1 1/2" pipe will need to be bored to fit both the tool port and the vacuum hose end.

If you have room  for it, a sweep elbow would be a better choice than a standard elbow.
 
 
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.

Electrical grade PVC pipes have even longer radius sweep ell's if you have the room...
They can even be 'STREET' style and can be had at Home Depot and Lowes, (and others in your area).

Just a generic Home Depot webpage, perhaps your location can not see this page intended for a "Georgia" audience...?

Jon,

Thanks a lot for the picture and yes, I'm located in France. I had a poor idea of what shape you were talking about.
 

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).

Glue or bolt it to a piece of material (wood or aluminum) that you can then mount in the 4-jaw.
 
 

How much do you want to bore it out?  Can't be much looking at the wall thickness.
Use your lathe to make a boring tool, then move to the drill press

Better still. Turn a wood dowel to the desired ID and use it to expand the PVC after slightly heating it

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

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.

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.
