From www.kevincaron.com - Artist Kevin Caron explains what J clamps are, why he uses them instead of C clamps, and a cool little modification to make them even handier ....
People have asked Kevin Caron about the clamps he has spread out across his workbench. Theu are called J clamps because they look kind of like a J. That's as opposed to a C clamp, which has a fixed arm on the top and a screw that goes up and down.
Why use a J clamp instead of a C clamp? The answer is simple: with a C clamp, if you want to hold 2 pieces of metal plate together, you've got to run the screw all the way to the bottom before it ever actually does anything. With a J clamp, the upper section moves. Then you only need, say, a quarter turn to tighten it, and you're ready to go to work. J clamps are a lot more adjustable.
J clamps also have much deeper throats. Kevin Caron shows a J clamp and a C clamp side by side so you can see how much deeper the J clamp's throat is. And they're just faster and easier to use. They just work better!
There are a couple of other differences between types of J clamps. Kevin Caron shows a J clamp from a German company that makes really high end clamps. They captured the foot on the screw by crimping the edge over around the ball that's on the end of the screw. So it can swivel, it can move a little bit, but you can't replace it. If you're welding right next to it and get it too hot or hit it with a grinder or whatever and it gets damaged, you're out of luck. You have to go buy a new clamp.
A different manufacturer attaches the foot with a nut you can change. You can buy the feet separately so you always have a good foot on the end.
Kevin Caron then took it 1 more step. He welded a little piece of angle iron onto one of the feet. Now he can clamp a piece of metal on its edge. It just makes the clamp more versatile. You can just buy the feet and swap them back and forth depending on what you're working on.
Of course, they come in all different kinds of sizes - Kevin Caron shows some of them.

Never heard of a J clamp before. They're called F clamps everywhere I've experienced them before.
There are super handy F clamps that have a quicky clamp/release lever.
Ive been in the trades (steamfitter) for 15+ years!! The removable/interchangable jaw is new to me, build your own for a specific task seems like a game changer.
I sure use the heck out of these!!
Thank you for watching and posting.
I've just found this guy and I love him.
Thank you for watching and posting! Welcome to the club!
I bought 3 Wilton J clamps with missing feet. I was able to fab up a new swivel out of a nut and flat disc. I drilled the nut undersize and heated it to go over the ball end. then welded a 1/8"disc to it and peened over the top of the nut. It's not ideal but it beats throwing them out. Either way, I agree, best clamps out there for my uses.
Tried that once with a Bessy that lost the pad. Didn't work out as well as you.
I’ve used these types of clamps for years, and I love’em.
Cool
Wayyyyy stronger than a c clamp too. We used them all day long with structural steel beams. You can exert a lot of force with one of these and dont have to fear it ever coming un clamped
cool foot design!
I think so too!
Good explanation, thanks for share, regards
You are welcome
I don't have any J clamps , but am going to get some . Thanks Kevin . :)
I use the heck out of all these clamps. Really need to get a few more just in case.
The same objects with different names depending on which side of the pond you are on. In Britain they are G clamps and F clamps.
So true! Long has they hold things in place, all is well.
Great tips! Thanks
You bet!
I made a half dozen for myself with some 1" x 3/8" flat bar a few connecting lugs 3/4" and some all thread 3/4" iirc
Oh yeah! Old school!
Never used C clamps in all my years of metal working. It seems obvious to me that those things are clearly obsolete in front of an F clamp
I agree. Thank you for watching and posting.
Heeeeyyyyyy Kevin.... why are you calling these "J-clamps" when the manufacturer's call them F-clamps? ;o) I do appreciate your sharing your insights.
That's the way I heard them described. Long as I have them to use that is all that matters in my book.
Those really are great clamps. Expensive...but worth it for sure.
Kevin, I do have a question that I bet you can help with...I work alone and often need to grasp 3 or even 4 pieces of material of a couple pounds or less at the same time, and they are usually oddly shaped (NOT lovely 90's and 45's and 30-degrees etc, but more organic). The reasons are complex, but I can't always weld one piece of an assembly to another, THEN add the third, THEN the fourth, etc. Have you ever created a reusable clamp -- not just a dedicated 3D fixture/framework -- that can hold multiple pieces at multiple angles so you can at least spotweld them in the right orientation? I was thinking something along the lines of those "Helping Hands" multiple spring clamp soldering stations, but those are way too weak for even smaller steel items.
Thanks for all your great videos over the years!
I have several of these www.bing.com/images/search?view=detailV2&ccid=luajfOVt&id=EE6FE3554511EEA4DC39F5A44F1538C84E019D26&thid=OIP.luajfOVtAK74ExF_JC_UtAHaHa&mediaurl=https%3A%2F%2Fcdn11.bigcommerce.com%2Fs-pb6zsppwmp%2Fimages%2Fstencil%2F500x659%2Fproducts%2F1274%2F2971%2F41100A-take2__24599.1508536154.jpg%3Fc%3D2&cdnurl=https%3A%2F%2Fth.bing.com%2Fth%2Fid%2FR.96e6a37ce56d00aef813117f242fd4b4%3Frik%3DJp0BTsg4FU%252bk9Q%26pid%3DImgRaw%26r%3D0%26sres%3D1%26sresct%3D1&exph=500&expw=500&q=magnetic+clamps+welding&simid=608013691234111801&form=IRPRST&ck=B79335371CBA209596C00F682B8E3E0A&selectedindex=136&ajaxhist=0&ajaxserp=0&vt=0&sim=11 and they work great!

@@KevincaronSculpture Excellent -- Thank you! The many images shown in that link really help generate thinking of a number good approaches.
Hey, Kevin, you are like a member of the family to so many viewers, so have you ever done a sort of a bio/timeline on how over the years you became the artist and youtuber you are today? If not, you really should -- it would be so interesting and I bet would earn a zillion views. You are clearly a great guy that we all admire.
Nice! Mahalo for sharing! : )
Thanks for watching!
Just watched one of your videos yesterday from 9 years ago and you should do a video on “how not to age”.
Thank you!!!!! If I could just get rid of the gray hair I would be happy.
DOUBLE DITTO ON THAT!!!!!!!!!!!🤣🤣🤣🤣🤣
Hey Kevin can you tell me the difference between Ag-60p consumables & AG 60 ???? I got a Ag60 torch and noticed some consumables are marked AG-60 & some are marked AG-60p. & and some say they will both fit AG60p torches. Thanks
Sorry Charles, but you got me on this one. I have no idea the difference. Anyone out there know the answer?
What brand has the replaceable pads?
BESSEY.
Name of the company that makes those J clamps with removable feet?
Strong Hands. Better than Bessy in my opinion and cheaper to boot.
OH BOY, SHOWING MY AGE!!!!!!!!!! THE FIRST ONES I BOUGHT WERE 24 INCH, AND THEY CALLED THEM " QUICK " CLAMPS THE HD MODEL WERE $300 BUCKS EACH!!!!!! STILL, WORK GREAT!!! SAY HI TO MARRRRRRRRRRRRRRRRRRY! 🤣🤣🤣🤣🤣
GOT TO GET YOU TO THE 100K SUBS!!!, JACK
Right on,, Wondered where you got off to! Thanks for watching and posting Jack!
Very similar to the "F" clamp. I can't help but wonder if they are as prone to slippage as the "F" variety. My dear old dad who wouldn't say shit if his mouth was full of it always maintained that they were called F'n clamps for a reason!
Bessey make the best clamps in the world in my opinion but are hotly pursued by Carver who make brillaint clamps too. Neither company makes anything cheap so expect to pay a small fortune for one clamp!
Welding is not for the faint of heart or cheap of wallet!
@@KevincaronSculpture That sums up welding quite nicely!
Where are the bessey ones made?
Hello my friend, did the welder company promise you a solar powered laser beam guitar / welder yet?
Maybe in a couple of years. Not holding my breath!
Where do you buy your clamps from?
Local welding supply.
And here I thought there was a new clamp on the market... but turns out they are bog standard "F" clamps.
They actually do make C clamps that slide, you just press a button. Harbor Freight Special !
Have to look for those!
@@KevincaronSculpture THEY WORK BUT A LITTLE FUSSY VS A SLIDE AND PINCH. THERE IS A PRICE DIFFERENCE.
A J-Clamp is just an F-Clamp doing a headstand..., 🤔🧐 see?! ↕️🙃🤯
there, debate over! 💯😉👍
Thank you!
You're welcome @@KevincaronSculpture , just stating the obvious. 👍
Interesting your C clamp is our G clamp Ahh the English language 👍
It's amazing the world can communicate at all.
It's a F clamp, Kevin.
So everyone has been telling me.
BESSEY
No such thing as too many clamps!!
Long has you have the space to store them!!
Challenge accepted!
Know your subject before you attempt to teach.
What brand is the best? Bessey? Where are they made
Bessey is a very good clamp! They are made in Germany. But Real Gear is a very strong runner as well. I like that the Real Gear clamps have changeable pads on the screw. Bessey is fixed. Been slowly changing over to Real Gear for myself.
@@KevincaronSculpture I've been doing alot of research and Bessy has some called Bessey classiX they have changeable end pads as well.
