Steps in forming a lip. (I) Firstly, start the bend right along the edge. You can easily manufacture tools with bifurcated ends, or perhaps use an adjustable spanner with the jaws closed tight for this. (2) Then bend the edge more using a hammer and dolly. (3) The main part of the panel will now have started to buckle, so stretch or shrink the edge as
already described until the edge is true — by which time the buckling in the rest of the panel should have vanished (5). It takes a lot of skill to throw an edge in this manner, though with practice you should acquire that skill. Illustration (4) This shows the alternative method of welding a lip onto a piece offlat steel,
