Need Help Building Desk


Okay, so I'm definitely a novice experience-wise, but I do have the knowledge to do this, I believe.

I'm trying to build a desk using four metal legs that I already have.

The top is an 18mm piece of wood that is 150cm by 50cm.

I haven't taken any photos yet, but the problem is this:

It seems to not matter at all what I do to fasten the top to the legs - as soon as it's standing on them, they rattle and eventually break.

So, I searched on-line and found something that looks JUST like what I built.. but it looks extremely sturdy.



So, if someone can explain to me what those people did, and how I can finally get this thing to be stable (I feel like I'm missing something vital here), I would REALLY appreciate it.

Hello and welcom Track, to the best darn DIY'r site on the web.

Thats a nice looking set up, there is a good chance the depicted setup is fastened to the wall for stability. or

The frame around the parimeter is steel and the top in fastened from the bottom up into the underside of the top.

With no apparent bracing I would say that this needs to be fastened to the wall for stability, regardless of the frame material.

Your top is only 3/4" thick. It has no meat to it to stablize the legs. The pictured table top is about 3" thick and the legs are inset into it about 2/3 of the way. The legs are also at least 3" in width so the area of inset is substantial. There might be internal fasteners you don't see.
If you want to keep the top thickness you have, you'll need lateral bracing to compensate for it's thinness.
As Jackofall1 said, anchoring it to the wall will help.

No, I definitely don't want lateral bracing.

But how did they fasten the 3" thick top to the legs? I also want to know that.

Then, I could add 1-2" pieces of wood to the sides and back and fasten the legs to those.

It just seems like nothing I do works. The legs literally wiggle. And this is with a dual-tipped 1/3" screen in the middle.

*sigh*

I suspect there is a thick mounting plate similar to this welded into the top of each leg.

You mean there is a metal plate attached to each leg and literally welded to it?

That's intense. I can't recreate that..

This would be a way to expose more of the leg on the outside while also giving you a lot more of the table wood to screw into.

And, of course, plates like this could be made as large as you choose them to be....... could even be welded into a frame that would run around the entire perimeter of the table top... although I can't see why you'd need to go to that extent.

That's what I suspect.

You CAN cut each plate, leg, and drill the holes. Then all you'd need to do is find someplace that will carefully weld the plates to the legs for you. Maybe $100 USA. (Roughly 60 pounds, in England?)

I agree with WillieT, there's more going on under there than we can see.
Photos of what YOU are doing will help us to help you faster.

I'll post photos when I get home.

But.. there is no way I can have this welded. I'll have to find another way.
