Tubing Bender Tight Radius / Brake Line

Most likely U don't have what's pictured..tubing bender... I do... but it didn't help a bit when I had to bend some tight radius ( in 3/16 in. / 4.7 mm... or thereabouts) to replace rusted brake lines on my Dakota.

It's so simple.. I was a little embarrassed to publish this "thing" ...
BUT THIS ENDED UP WORKING MUCH BETTER THAN A REAL TUBING BENDER.
Actually a real tubing bender doesn't come close to bending a radius as tight as these "things".
