Drilling holes in PVC pipe...

[white]

don't drill the holes too big and then find out you can't thread them anymore.

 

[IronWing]

Use really slow drill speeds. You want to minimize the amount of plastic melting to the drill bit.

 

[Rastus]

Don't use PVC, there are much better materials out there to make a bong with.

 

[Scarpozzi]

PVC is hard to drill when it's at too low of a temp. I suggest heating it with a propane torch before drilling through it.

 

[Zontor]

Be sure to hold part your drilling in your lap....and push really hard on the drill....

but might try to put masking tape on top of it to get you starting, and start by making a small hole, then use the larger drill

Why masking tape?

if its a small pipe then the drill can easily slip, easier to keep it steady with a masking tape

Tape also helps reduce splintering and rough out.

Doesn't sound like it's an issue, but use twist bits if possible. If you need to use a spade bit, make sure it's sharp & go slow.
I had a bad experience along those lines.

I've found making a small divot first with a dremel helps with this issue as well.

PVC is very easy to drill.

If you are a beginner, a drill press can give better results especially if the holes have to go straight through.

What's the diameter, schedule and application?

Its two inch diameter, not sure what you mean by schedule, and the holes are going to be threaded to fit metal nozzles which will converge 6 tubes to one larger tube.

Also, any tips on capping the ends of this pipe?

2 inch diameter hole? Then I would use a hole saw.

Use a condom and a hose clamp to cap the ends.

Avoid glue if you don't want little ratsies to choke on fumes.

How about cutting PVC? Can I do that with a normal Hand Saw?

Did you notice the first sentence of his post?

[RollWave]

on that subject, would duct tape work if I cant find any masking tape?

[Juice Box]

There will be a hole in the PVC pipe when you are done :shocked:

 

[RollWave]
