Easy Flare

[PyroJoe]

This weekend I needed a flare on one of my projects. I setup a solid steel bar in the vise and tapped the top of it with my peening hammer.
This drove the bar end down onto the lip of the tubing that needed the flare. The other bar end rotates slightly in the vise.
Slowly rotate the tube while hammering.

It worked well enough for "budget" tooling.

It is considerably easier when the edge of the tube is glowing red hot.

UPDATED: Here is a simple tool for flaring thin walled pipe, posted by GRIM (halfway down the page):

Here is a flare tool I made from a sacrificed adjustable wrench. It will slightly decrease the ID of the flared pipe at the base of the flare, other than that it flares well.

The bottom jaw is rounded perpendicular to the handle axis. the top jaw is rounded parallel to the handle axis.

Should work with either metric or standard adjustable wrenches.
Probably a second joke there about flaring metric or standard pipes.
