How to make compression members?

You know, these little gadgets. I tried Home Depot but they lacked tubing thin enough. Any ideas?

The link says 1/2 inch PVC...

THey have something on line that should work:

http://www.homedepot.com/prel80/HDUS...gln.0&MID=9876

I can't imagine they wouldn't have some 1" or under in the store. 1" should be small enough for that purpose.

EDIT:

I just checked the link, and it didn't work. Search for "PVC 1/2" and they have 1/2 risers in packs of 10 at 8 inches for $5.49 and 12 inch individual for $6.95...

Hmm, didn't think of Home Depot online. BTW, your linkie makes no sense. I don't even know how to do a search on HD's site myself. A search for "PVC tube" gives useless results.

I just realized that my link didn't work... I editted to show the search (PVC 1/2)

Lowes.com lists 10' sections of 1/2" PVC pipe for $1.56 but it lists my local store, so I don't know if it is in store pickup only... I think home delivery of a 10' pipe would get expensive....

Any large hardware store should have something in the right size range... (under 1") Maybe even garden supply stores, as it could also be used for sprinkler systems.

Or a local plumber... Call and ask if they'll sell you a few feet of 1/2" PVC pipe.

I suppose my concern is that I'd like to get the parts in person. I have a few of the little discs from wheel deliveries...

Does the "half inch" refer to the inside or outside diameter of the pipe? Outside would clearly not work with the little discs I have.

No, they are not. Pipe (NPT) dimensions are "nominal" and, in smaller sizes, not even close to the actual diameter, either inside or outside.

The actual outside diameter of several pipe sizes, and the corresponding inside diameter of schedule 40 pipe, all in inches, are:

1/8" NPT; OD = .405, ID = .265
1/4" NPT; OD= .540, ID = .360
1/2" NPT; OD = .840, ID = .618
3/4" NPT; OD = 1.050, ID = .740
1" NPT OD= 1.315; ID = 1.043

Schedule 40 is most common in metal pipe while a lot of PVC is Schedule 80 which has thicker walls and, therefore, a smaller ID. The OD's remain the same for all nominal sizes in all materials.

BTW, PVC pipe is available in 3' lengths at any hardware store or home center in various standard diameters at very low cost. All you need is a hacksaw.
