A

Mark off where the centre of the bend is required.

Take a NEAR WELDING heat and with the hot chisel on the mark, make a cut nearly halfway through the bar.
Bend the bar over bick to a right angle keeping a good radius on the inside like this -

B

The inset is made from a bar of the same thickness and should be about "" longer than the width of the metal from which the bend is made.

Cut into both sides with a hot chisel and leaving just enough in the middle to support the end when it is being tacked into place.

Take a LIGHT WELDING heat on both pieces and tack the inset into place with the bend over the hick like this (shown cold) -

C

When securely in place break the inset of the bar off at the notches and dress the cut face so that it looks like this (shown cold) -

D

Take a FULL WELDING heat and, to ensure that both sides of the inset are welded right into the corner, strike the first blow downwards on the top of the inset so -

E

Immediately strike the second blow endways like this -

Continue with alternate blows until the weld is solid.

F

To keep the greatest strength in the bend, work up the corner on the anvil face, like this -

Do not place the inside of the corner over the edge of the anvil or the bick as this will reduce the section of the metal across the corner and so weaken the bend.

G

The completed bend should have a square outside corner and a good inside radius as shown here.
