SR-11 plugs

[Deweycoon]

Can someone tell me what size hole saw blade you use for HDPE SR-11 pipe?
I have tried the standard sizes I have at home and they are to big/small.
Is it a metric size?
I only need 14 plugs and the plugs would cost $18 with the shipping/handling.

It's a 2 1/8th hole saw. I know this for a fact I've made hundreds but they will be a bit oversized but thats what you want. I generally use a rubber mallet and tap them in. Some companies that manufacture those plugged tubes use a press to press fit the plugs.

I tried that 2 1/8... I geuss I'll have to get more aggressive with the pounding.
My plug come out measuring 1 15/16", is that right?

How in the world did they come out like that? I just went and measured like 20 plugs i made the other day and there all about 1 7/8ths. The plugs you made maybe a little to big. But thats the same hole saw I've used on all of mine and i bought it at Lowe's. Plus im using a drillpress so the plugs should be as big as they get.(not as much wobble as using a drill by hand)

Well the general I.D. of 2" SDR-11 IPS HDPE is:
1.926 in.

And if your plugs are 1 15/16ths thats:
1.937 in.

That should work.

I am using a blade from a cheap set...very thin metal.
I am going to make the plugs using a heavy duty hole saw blade at work and they will come out fine. Thanks for the tip.
PS - I did get the plug in.

I've been thinking of another route to make plugs lately and if you have the means, I'm pretty sure it would be easier and faster. Wonder if you get a long peice of stock like say a 4X4 post or even laminate a few peices of thinner wood together then throw it on a wood lathe. Turn down the stock to the diameter you need then use a miter saw or chop saw to cut the plugs the thickness you want. Right now, I dont have access to a lathe but when when I do, I'm gonna try it. Seems faster to me.

put your drilled plugs in the freezer for a few hours so they contract and then put them in your tubes and when they warm up will expand and fit nice and tight

I use the 2 1/8 bimetal holesaw from Home Depot or Lowes. Its a tight fit so I take a dull pocket knife and bevel the inside of the pipe. It doesn't take long and worth the extra effort. Then pound the plugs right in. Be careful if you are using soft pine though. Sometimes the wood can tear and split if its not seated properly. You'll be able to tell if your nails or screws go in way too easily.

Thank you for the offer. I did get the right hole saw blade and I made the plugs.
