This is my version of a Wire Clamp Tool.
This is a great tool for making pipe clamps from wire.
The claps made with it are low profile and no snag.

Step 1: How I Made it -1

Picture of How I Made it -1
The parts I used.

1.   5" length of 1/2" copper pipe
2.   2 of 1/2" copper end caps.
3.   5" x 1/2" spring. ( I just stretched the spring to get the correct length ).
4.   5" x 3/8" threaded rod. ( look in the electrical conduit section of the hardware store its cheaper ).
5.   5/16" x 1" bolt.
6.   3/8" wing nut.
7.   2 of 5/16" nuts.
8.   Old o-ring.
9.   2 of 1/8" x 1 1/4" roll pins.
10.  1of flat washer with 3/8" hole and 1 of spring washer with 3/8" hole and 1/2" diameter.

To Make the tip I took the 5/16" x 1" bolt and clamped the bolt head in a hand drill.  I spun it in a counter direction on to a rotating belt sander to get the taper. The notch I made with a small round file. Using a press drill I drilled a1/8" hole just under the bolt head.

The end caps I drilled a 5/16" hole in the center of both and a 1/8" hole on the sides of one cap.

On the 1/2" copper pipe I cut 1/8" x 3 5/8" slot on both sides using a rotary disc cutter. I put the end cap with the side 1/8" holes on the pipe an marked then removed and drilled the holes in the pipe.

To assemble the tip I put the 5/16" bolt tip in the pipe  and then the end cap over aligning all the 1/8' holes, then driving the 1/8" roll pin through with a hammer.

I have one of the commercial made ones I bought at some trade show and use it when needed it does not have a spring and that would be a very useful addition. Never thought of making one before great!!

Hey, I'm trying to build this, and of course, 5/16 nuts and wingnuts won't fit on a 3/8 threaded rod...
DavAnt DavAnt1 year ago
I get that you drill out the nuts, but you still can't thread them on like you suggested...
MartinMakes (author)  DavAnt1 year ago
Sorry for that. I have some of the sizes mixed up. You are right it is a 3/8" Wing Nut
and the 5/16 nut for the spacer, that you would have to drill out and not be able to thread on.
I will correct the instruction soon.
'cuse my ignorance how do you use it, could you show this in your instructable?

I added "Step 4: How To Use It" I hope this helps.
Brilliant! Couldn't be clearer, thanks for taking the time, much appreciated!

Yes. I'll see what I can do soon.

These things work great! I made one several years ago out on an old turnbuckle. It still gets used when needed.

Nice job on the tool you have made there. I made one similar several years ago and I may have to go out to the shop and find it if I can. Your cuts in the sides do look a lot better than mine do.
Keep up the good work
