DIY: How to make braided stainless hoses.
Well forgive me if I've missed it, but here's how to make your own hoses that have reusable hose ends. The process is almost identical for crimp on, but I doubt if anyone has a crimp machine at home and would not know how to use it. IF you do PM me.
I'm using a rubber Stainless braided hose with black nylon sheathing. It still works the same for unsheathed.
First you mark the hose at the desired length. You must make it about 1/8" short for the ledge in the top of the hose end(on both ends). Use a piece of Electrical tape to hold the braid together while cutting.
I've seen a lot of debate about using hack saws, dykes/side cutters, or cut off tools. USE cutters like I am using. Hacksaws and cutoff wheels leave debris in the lines. Nibble at it, just cut through the wire leaving the hose intact. This keeps the round shape. Then nibble around the hose. it will take about 5-6 cuts on a small line. A lot more on bigger ones.
When you are done re round out the end. Normally your fingers work fine, but a screwdriver can help a lot.

Make sure the hose is cut square. I like to use the hose end to compare it to.
Then look in the hose end and verify if it is push on or Threaded on. If it is threaded then it should be left hand thread.
Measure the depth the hose will go into the end. And retape the hose, Then verify the tape is on in the correct position. Very carefully get the hose started in the hose end.

Push the end all the way on and look inside to verify the hose is completely butted up against the inside. Then pull it out about 1/16 of an inch. This gives it room for the hose to swell into place as you install the inner fitting. The 1/16" also makes it much easier to get the inside piece started.
Redo the tape so it is at the very bottom of the fitting.
Then start the inner part by hand. I'm using the towel since I don't have soft jaws for my vice. If you have backed the hose out 1/16" and still can not get it to start easily. Then Skive(scrape the inside of the hose), just a very small amount. When Skiving the hose do it with the hose pointing down so and cuttings fall out and verify they did fall out.
Once the end is started grab the hose and push into the fitting while tightening down the inner piece. Only use a open end wrench that is the correct size. I've used the box before and had my wrench stuck because the swivel end was larger then the make up flange.

Give the end a good pull to make sure it is secure. Then Verify the hose did not get pushed out of the end.
And You are finished. Flush the hose with simple green and let it dry before use. A little compressed air will help it dry out.
Do not use oil or soap to make the ends go on easier. It will make the end fail under pressure.
Also if you do not want to damage your fitting. you can tighten another fitting into the top of the hose end and wrench on that while screwing the inner piece down.
