Heavy Duty Bar Clamp

You can never have too many clamps, so I made 2 more for fun. These are based on an old style which i was first introduced to in this video.

At first while making these I was thinking they were easier to build than my clamps, but then I realized that it was about the same amount of cutting fitting and gluing. I purposely tried to make them look old fashioned and abused, thus the grip handle and the rusted hardware. I wanted them to look like they were found in a barn somewhere, yet remain functional.

These clamps have a max capacity of 30 inches and a workable minimum of 5 inches. With the screw being so long the actual minimum is 2 inches, but that involves a LOT of screwing on the grip.

The 3/8 inch threaded rod was left over from a failure of early attempts at making my hand screw clamps. It’s a little long, but since I didn’t pin the handles, if the epoxy should ever let loose, I’ll shorten the threaded rod.

After distressing the pieces and aging the wood using tea, vinegar, rusty nails, and bleach (not all mixed together!) I wiped down the parts of the finished clamp with boiled linseed oil to protect the wood, keep glue from sticking and make it look old and then restored.

Great clamps! I like ‘em a lot. If I get some time this weekend I may make a few. You are right, you can never have enough clamps.

Nice clamp Dave. Did you coat it with anything that will prevent glue sticking?

Oldtool,
After I aged the wood through my secret formula, I coated it with boiled Linseed oil. (One more thing that I should add in the description.)

I actually have a few of the originals that are about 6’ long that I’ve been keeping around to use as templates to make my own at some point. Yours are getting me motivated. I think I will have to build some next week.

I think about these clamps, but I want to make wooden screws. I expect when I bring tools for threading.

These are heavier duty. By that i mean they can really be cranked down on without the jaws showing any movement. I’d say they’re about equal as far as usability. On the Nine the stop is bolted on. On these two the stop slides in place, but it tends to slide off when you’re just carrying them. Takes a lot of cranking though with the way I made the handle. Don’t forget that I intentionally made these to look old fashioned. I’d probably put a crank of sorts on them if I were making them to be new and improved, maybe along the lines of the handle on the nine. Thing is that if you need THAT much pressure, shouldn’t your joint be a little truer first?

Dave you are right I have more than once in my comment asked why people
want to squeeze with so much pressure since it wont make the glueing better
becourse they press all the glue out of the joint
some times when you are making big things like a door it is great to have long
bar clamps that doesn´t bow
in general I´m much more to the idea of using light pressure clamps
like the klemsia clamp type so many have made themself here on L J
