Make hyd hose "shield" yourself

[Rustyiron]

In going thru my pics for another post, I saw the tubing "slicer" I made to slice regular plastic tubing (well pipe, pex tubing ect.) into that curly hose "protector". They charge a fortune for that stuff! I just took a short legnth of (about) 1 1/2 black pipe, guessed an angle to cut it on, and made up a little rig to hold a short pc. of a heavy sawzall blade. I figgured that it was pretty hard, and made a little "hook" type cut in the side of it with a little cut off wheel. It really works well! The pictures are not much, and if you would like a better pic or description, I'd be happy to help.

Neat idea.
I could use one of those myself

That is the most unique idea I've seen in a while. How do you establish the pitch of the helix? Looks quite uniform.

That's a great idea. Is the thumb bolt used to help guide your pipe as you're turning?

How do you turn it? By hand?

 

[Rustyiron]

The angle of the blade makes the even spacing. The pipe is 1 1/2" and works well on std. 1" plastic well pipe. For smaller dia. tubing, I stick a pc. of EMT, steel or pvc inside the (bigger) pipe and hold it down with the thumbscrew (towards the knife) against the cutter. At about $5/ft. to buy the stuff, this works well. I hold it in the vice and twist the pipe to be slit with a pipe wrench.

Thanks for the info. There's a few hoses on my old backhoe that need a little more protection since the backhoe is used mostly in the woods on the farm. Every little bit of protection helps.

If I could just find out where to buy me a "Round-To-It" I'll get right to building me one.

Great idea.
Looks primitive; works great.
What's not to like?

Nice work. Wish I had the tools available to build this kinda stuff.

That's one of the slickest ideas I have seen in a long time! :thumbsup:

You should have started up a company and made a mint selling to Home Depot with that idea. Minimal capital investment.

Very clever!

I have bought some of the spiral sleeving like that for my hydraulic hoses. Now I will have to give your technique a try and build one of those jigs.

On the ends of the spiral sleeving after it is wound around the hydraulic hose I use a tie wrap to secure it from coming unwrapped.

I'm trying to figure out if your jig is made on an angle or is it just the pics? I'm also trying to figure out how to make it motorized!

That is a great tool. How do you turn it or how do you turn the PEX tubing? It looks like the cutter could be mounted in a lathe and let the lathe turn. I would want someone with a hand on the switch ready to turn it off if necessary.

 

[Rustyiron]

A lathe (slow, metal) is an excelent idea, I was thinking of an electric pipe threader. I stick it a vice and turn the tubing and it feeds in at a consistant rate, no reason it would not work by spinning the cutter.

 

[TomSeller]

This is a great concept but the original configuration is about as far as I would take it. How much of this do you need anyway? The angle appears to be obtained by the blade being offset from the grinder wheel when it was ground down.

It really only takes a few minutes to make 8' or so, I only use it in chaffing or wear locations.
I'd be happy to try to give some more pics or a measurement or 2 if someone wants to copy it. Pretty simple, it worked on the first shot at it and if a guy had a vertical mill, he could make something that looked much better:laughing:

 

[jwmorris]

Rusty, everyone that looks in BIY wants to copy it. More pics are always welcome. After that you will shortly see a PTO powered version.

Id lover to see more pics maybe even a utube of it in action.:thumbsup:

Sorry, I kept forgetting to take some better pics during the day (light). It is as simple as it looks, I'm just going to make a list of things to keep it simple.
1 The angle is 20* to make the cut in the pipe for the washers (mounting surface) this angle controls the width of the spirals. On 1" well pipe, the spirals are about 1 1/4" wide. With the small 1/2", it's more like 5/16.
2 Those round things are just big washers, about 3" across (you'll need to "egg" them out to accomodate the angle)
3 That "cutter" is a small chunk of a wide sawzall blade, the cutting "hook" is just cut with a small grinder with a cut off wheel.
4 I welded some pretty heavy lumber banding to the lower washer to act as a spacer (equal to the cutter thickness) as well as a guide to keep the cutter from wanting to rotate when cutting. The banding is just the first thing that I found in the shop that was close in thickness to the cutter.
5 The thumbscrew is to hold a smaller pipe inplace when cutting smaller tubing. This keeps it down & against the cutter, when cutting the (blue) 1" water pipe, it works just fine in the 11/2 main black pipe.

It feeds it's self through, I just use a pipe wrench on the "in" side of the tubing, with the fixture in a vice. Can't think of much else to tell you, I just "cobbed" this together and it was done. If you had some milling equipment you could make a nice recess for the blade, and instead of those "egged" out washers, a nice milled oblong hole. I used the sawzall blade figuring that it was pretty hard and should hold an edge.
