I have some bundy pipe and want to cut it down then add a bump in the pipe like the one shown in the pic so that I can attach a water pipe, what tool is needed to do this?
yep flaring tool, basically a ball bearing which when screwd makes a bulge in the pipe.
DIY project invloved flaring 10 pipes. I was dead at the end of the day...but with much larger arms...
the right tool is the plumbers one, but quite expensive to buy for just a few turns. you better of taking to some where for them to do it for you like power steering shop or hydralink etc,
Plumbers use a crox tool but it won't come in the sizes you want. It's used on copper pipe with ID's of 12mm, 18mm and 23mm - more commonly known as 15mm, 20mm and 25mmcopper. You can get bigger ones but only larger companies that do commercial jobs will have them.
BTW, you dont really need the bump on the inner part, its only there to stop the hose from slipping UP the pipe, and that is very unlikely, only if your clamp was loose would it move,
not if you use the proper tube cutting tool, instead of hack saw,
it looks like a monkey wrench but with a round blade on it,
you spin it round the tube a few times and it snaps off real clean,
you should be able to find these tools at auto shop or hardware shop,
not too badly priced for both cutter and flaring tool,
