I made a new pad for a small 1-1/4" No. 566 clamp using the head of a stainless steel Allen head screw, by drilling a 3/32" hole in the center before cutting it off. (I used the Allen wrench to keep it from spinning while cutting, then clamped the wrench in a vise and put the head on to file the cut flat).

The little pin on the end of the screw was bent over, but soft enough to straighten back out. I'm guessing someone used the clamp on something round and it twisted the pad off when it slipped. The clamp had also been bent, but the pickle fork won the fight. I was impressed by how much force it took to straighten it back out.

Here's a No. 558 I made a pad for years ago, to be able to clamp round stock. It also works fine on flat stuff. I probably should have made another one of those using a piece of angle iron, but the screw head was easier and I was lazy.

Here are a couple of Hargrave No. 1 spring clamps, compared to a pair of Jiffy Clamps. They're very similar but the Hargrave clamps are slightly nicer.

It was fun to see this thread get bumped. Good timing.

A couple more clamps...

20260106_150720.jpg

A 4 inch Hargrave No. 43 and a 3 inch Hargrave No. 44 superclamp...

I have a question for the more knowledgeable here... the Cincinnati catalog lists No. 43 clamps in 4, 6, 8, 10, and 12 inch flavors...

I have a 4 inch, three 6s, three 8s, and a 12... I have been actively searching for a 10 inch clamp for almost a year and have never seen one. I haven't even found any pictures of the 10 incher on the internet...

I'm assuming they actually did make the 10... are they really that uncommon?

Has anyone else out there seen one of these elusive beasts?

I have some 10s of the 540 standard clamps, and an 8" of the No 44. Nothing from the No 43 line.20260106_211808.jpg10s, 12s, and a 14 540. One of the 12" clamps is a Chicago

I've just acquired two more Cincinnatti/ Hargrave clamps...

A No. 45 4 inch...

20260220_213717.jpg

And another No. 43 4 inch...

20260221_233405.jpg

The 43 was an ebay buy, the seller disclosed that the screw was frozen. A little oil and some 'elbow grease' freed it up... it works pretty well now.

The 45 is a standard duty 'deep reach'... 4 inch opening, 4 inch depth, and also has the bronze screw like the 43 does.

I've just acquired a Cincinnati/ Hargrave 18 inch No. 42 clamp...

20260225_132049.jpg

I'll need to replace the swivel pad and straighten the handle... otherwise it's in decent condition.

McMaster sells them for those of us without the skill set to make our own. Of course the one I need is between sizes.

I usually pass on them if they are missing the pad. This is good to know if I find a clamp that I want that's missing the pad.

Nice that they pop into place.

I have replaced several of the pads with replacements from McMaster... so far, I've been able to get the ones I've needed.

If I have to, I'll machine one... and I may have to with this clamp. The ball measures 0.590"... the closest offering from McMaster is 0.575". I have one ordered... we'll see if I can get it to fit.

A while back, I bought a Cincinnati/ Hargraves No.43 8 inch c-clamp with a missing swivel pad... I began machining a new pad for it today.

I chucked a piece of steel in the lathe and drilled a 31/64" hole, then used a 1/2" ball nose end mill as a boring bar to finishe the hole to 0.605" diameter with a somewhat round bottom...

20260515_170416.jpg

I then machined an internal groove inside the hole for a lock ring to hold the pad to the screw...

20260515_172110.jpg

The screw fits nicely...

20260515_172250.jpg

I got into my stash of surplus springs and found one the perfect size and wire diameter...

20260515_172516.jpg

I'll cut a coil off it for the lock ring.

I ran out of time today... I'll finish machining the outer contour later.

I finished the swivel pad this morning...

I made the retaining ring by cutting one coil off a spring...

20260518_084456.jpg

The ring goes around the neck of the screw... between the threads and ball, then snaps into the internal groove in the pad...

20260518_090418.jpg

I did leave some scratches on the top of the pad... the ring proved to be pretty difficult to install. I'll smooth the sharp edges out with a dremel, but the pad is going to be scratched up anyway in use, so I'm not too worried about it.

The pad is on and functional... another #43 put back in use.
