Clamp Extensions

Here are some clamp extensions I made recently for my coffee table project. My longest clamps are 48” long, but they weren’t long enough as my 2nd picture shows. So what to do? I suppose I could have bought some pipe clamps and tried to find pipes that were a good size. But Instead I decided to make these things, which ended up working quite well! I made sure to countersink the bolts so that the extensions can lay flat. Also the 3rd picture shows how I left the very bottom piece longer than the middle piece. That is to keep the extension from slipping off the edge if I really crank up the pressure. The result is that I have to weigh down the opposite side, but that wasn’t a big deal. I clamped to full pressure 2 of my strongest clamps per extension set, and they worked like a charm! I’m very pleased with them, and I’m going to keep them for sure.

I doubt that I’m the first person to make something like this, but I will say that I conceived of it without having seen them. It’s fun to invent solutions like this in my opinion. I’m almost as pleased with the clamp extensions as I am with the table! Well, maybe not that much.

Yeah, no problem! I’m just happy that someone can take something helpful from me for once. I’ve taken more than my fair share of ideas from this site and I plan to take more in the future!

Great, you just gave me one of those “DUH” moments.
I have struggled with how to clamp boards without longer clamps before.
This seems so obvious now.
Thanks for sharing.

Excellent idea. Have to look into making a few just in case. Would have been nice a few weeks ago when I went and got a longer pipe. LOL
