Topic tags/keywords: question clamp pipe pipe-clamp

Hi there,

This is my first time posting o this forum – and I’m still a rookie in the woodworking world so I apologize if the question seems amateur-ish! I need some pipe clamps for my first woodworking project (ongoing) which is my workbench. I’m going to be laminating about 25 2X3s to form my bench top, so I was going to use some pipe clamps, like the Bessey ones, to help glue up everything firmly.

The only problem is that I can’t figure out where I am supposed to get these pipes! Lots of distributors sell the clamps, but almost none that I can find sell mating pipes. I assume that I should be looking for standard black threaded gas pipes, but I can’t find any in the 3/4” size. Are these hard to find? Where’s the best place to look?

I’m thinking about just going for bar clamps if I can’t find any in the near future, but if anyone who reads this has an idea where I can start looking I would much appreciate it!

Most all of the Big Box Lumber Hardware Stores down in the states carries black pipe in various lengths, ie: Home Depot, Lowes and such. I am not sure what comparable stores you may have up in your neck of the woods.

I belive galvanized is preferred to the black to prevent staining of your work…. As Panhandler and Max said, both my local Home Depot and Lowes have the pipe. If you get a variety of sizes you can swap them out for different projects.

I agree that the galvanized is better but either will work. Big box stores and hardware stores carry various sizes.

Any plumbing supply store could fix you up with 3/4” black pipe probably cheaper than the box stores. Get both ends threaded, that way you could extend them with pipe unions and get longer clamps if you ever need them.

Thanks everyone – you guys are quick! Yeah, checked out the HD in Bellingham, WA near my home and they carry all those types of pipes. For some reason, nobody seems to carry them up here in Canada. I found Home Hardware selling PVC pipe, but I would be a little hesitant to use PVC although I suppose it would probably work so long as it was threaded.

Thanks guys, looks like I have a trip to Bellingham in my future.

Take care,

Even Sch 80 PVC would have too much give for this application.

Don’t they have a Rona Store in your neck of the woods? They have black iron pipe. I don’t like galvanized because the zinc coating is soft and can make your clutch discs fail to grip properly. Plus, the zinc may react to the tannin in some species, mainly oak. I think the old Jorgensen literature specifically advises against using galvanized pipe. Check this:

Wow, I make a lot of stuff out of red oak and can’t say I ever got any discoloration from the galvanized pipe, never had any slip either, and they’re all approaching 15 years old. I must live right. :)
