Time for another project ... need to put a 90 degree bend in some
1.25" square section tube.
Not bought the section yet but guessing something like 16 gauge
(0.064") or maybe I will need 14 gauge (0.08")
Obviously the bend radius will mean a reasonably gentle bend.

I have 2 questions if anybody has experience of such things.

# What is the minimum bend radius, I'll make sure I keep above this.

# Is this a practical bend to do at home ... or should I go to a
fabricator and buy it 'bent'
