Cutting AN braided hose

[Doug Liedblad]

I used to cut AN hose using a dremel tool and cut off wheel. Wrapping it in tape first.

In looking for a better way I found this:

A method I would never have thought of.

I've not tried it yet but will soon.

I'd post this in the wiki if I knew how.

Looks simple enough. It reminded me seeing my uncle cut hoses that way in the 60s. He was a shop mechanic for a trucking company. But I believe he used a lead brick.

I tried that method, learning it directly from the owner of that shop.

I sharpened a wide chisel and gave it a go. It didn't really work out, although I don't know why. If Doug is having better success, I'd love to know.

Aha, I didn't use the alu block as a foundation when I cut. That probably explains why my attempt failed.

I'll have the wide chisel Wednesday and let you know.

I suspect it needs to be very sharp, maybe sharper than intended for bricks.

The soft block is important to at least not dull the chisel and maybe to make a better shearing action.

Also the solid backup.

Update later this week.

Tried it just now on AN3 line.

Works great. Much better than the tape and cutting disk method.

I used the chisel as it came out of the box. It could be sharper and should work even better.

I have an easy way that I used for all my fuel lines.

1) Use painters tape to wrap the area you want to cut
2) Take a hoseclamp and tighten it down at exactly the point you want to cut
3) Use a fine-tooth hacksaw to cut right at the edge of the hose clamp (IIRC I use ~30 TPI)
4) You may need to use wirecutters for the final few (4-5) strands at the end
5) Having a vise will also help keep the hose in place though in my case I was able to just do it by hand

I was amazed at how quickly and easily I was able to get the job done. And yes the chisel method is even faster but I was too lasy to go out and buy one :)

I used the Dremel on taped hose method, and found it adequate. If I ever need to make more, I think maybe I will try this chisel method. Gotta love caveman technology!

What I really want to try is the Koul Tools sockets, but I reckon I don't need to make hoses regularly enough to justify the cost. Anybody used one of these? The demo video on the web page is damn impressive to me.

[Doug Liedblad]

Any way that gets the job done is fine.

I've used the dremel, hacksaw, and now chisel method.

The chisel method is by far the best I've found. I suppose you could buy the special cutting tool or a cable cutter and it would work better but with a chisel from Amazon.com for $6.18 and a block of alumnum I had lying around I'm set for life.

I used something like the Kooltool many years ago to assemble braided hose for a welder to braze during a summer job. They work but I'm too cheap.

(They lowered the price since I bought and now I'm really:mad: ).

The price dropped thirty-four cents. That's like, one good blip of the throttle. :)

Yes but I still feel cheated.

Note for cutting the hose: The big hammer is essential!
