What Size C Clamp is Best?

As a proof of concept, I made a C-Clamp out of wood. I intend to eventually make a few more, but I’m wondering what would be the most useful size to build. The one in the photo is about 6 inches square with the clamping capacity of only 2 inches with a 4 inch deep throat. Any suggestions?

Tough question – it depends on your needs. I have C-clamps from 2 inches to 8 inches. I use the 6 inch ones the most – mostly for holding jigs to my bench. Building ones with throats that are deeper than their reach seems like a good idea – those are harder to find.

The capacity between the jaws varies based on the use, but the C clamps I use the most have a very deep throat. Got a 6 pack of Jets years ago and it’s amazing how many times those things come in handy…

It seems I grab the 3-4” C clamps the most. I do wish they had deeper throats.

It sounds very like I should keep the deep throat, since those type of clamps are expensive in metal. just did a test and my little example clamp (above) is already big enough to clamp the finger board on my wife’s dulcimer. Since that’s the most likely use I’ll have immediately, I think I’ll make a few more of this size. I can move up larger from there, maybe going in 2 inch increments to maybe 6 or eight. I know I can add reinforcement with a length of threaded rod near the spine. I like the primitive look of these.

I think an upper case ”C” is the best!

I have two deep throat C clamps and use those a lot.
When my local OSH, Orchard Hardware Supply, moved to a new location they sold off a lot of items instead of moving them and I bought two of these for only $20@.

And I wish I would have bought the other six that were avaiable!
