Topic tags/keywords: computer table pipe clamps pocket hole jig aluminum bar clamps

I am a beginner. I am about to start a simple computer desk. On a tight budget. This video “https://www.youtube.com/watch?v=6FWnPRRT5JU” & my new gig working from home inspired me to take this on. I am sure there will be several questions that come up. Here are some I already have, please help!

One tool that I am considering buying are pipe clamps. 2 reasons: Obvious one is to clamp the 2×10’s together while the glue sets up. Two, to get the boards up off the table so it doesn’t glue itself to my work table. Here are my questions:
Are they necessary?
If so, 1/2” pipe or 3/4”?
Brand of clamps do you all recommend?
And, my table will be 60” wide (long). If the clamps are important, how many sets?
I am also considering Aluminum Bar Clamps. But I still need something to go under the table top so it won’t glue to the table. I am concerned that the Alum Bar Clamps might not hold up under the weight of the table top (if I put 2 under to get it up off the table – and they might glue to the table due to their shape).
As shown in the video, I’ll be using the Kreg Pocket Hole Jig. I am wondering after I apply the glue, if I go ahead & also apply the pocket hole screws, will this apply the necessary pressure instead of the clamps?

It’s great to be part of this group. I look forward to your expertise!

Welcome, Keith!

Pipe clamps are a great economical choice and they will work well for this application. I like the Harbor Freight ones. They are cheap and work fine. Definitely get the 3/4” ones. The 1/2” ones will flex considerably.

The more clamps, the better. I would suggest at least 6 clamps for that project.

I would skip the pocket screws on the top. If you glue and clamp it, they aren’t necessary.

If you want to skip the clamps, and you can get the boards to stay flat and tight, the pocket screws will be fine.

Clamping pressure fans out at a 45° angle. If the seam is in the middle your first clamp should be about 1/2 the width in from each end and then spaced a little less than the width apart.

Use clamping cauls to keep things flat.

Wax paper or alum foil between the glued pieces and the bench will prevent adhesion.

Make sure you get 100% coverage on the join but don’t drown it in glue. A small piece of lexan makes a great glue spreader. Hold it against one edge at a slight angle for a thin, even, glue layer.

Pipe clamps are OK, but are heavy, bulky, and a bit overkill. F-clamps (bar clamps) work well.

After considering the suggestions above & filtering thru my budget, here is what I am thinking. See if this will work –
Wax paper or aluminum foil under the glued areas. After glue is applied, apply 4 aluminum bar clamps on top AND add the pocket hole screws. Will this add the same amount of (or close to the same amount of) pressure that bar claims would offer with no screws? Thanks you guys for your advice!

No drawing. But here is a photo of how it should look like:

I’d recommend the A frame type pipe clamps. They are much more stable and easier to use. Only a couple bucks more. HD, rockler, and grizzly have them. I’m sure others do as well.

Good luck with your project.

Cauls should be used for flatness. This will also raise the workpiece off the bench. Once clamped up stand the glueup against the wall to keep glue off the bench.
