    Default Cutting AN braided hose

    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.

    How I used to do it http://www.dsmtuners.com/forums/arti...-fittings.html

    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.

    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!
