Tom's bending of corrugated tin sheets for Dutch barn roof

This is a bit of background as to how I creased the tin sheets to form an upstand on the lean-to side of the barn.
Was difficult to find any info on how to do it, so kind of made it up as I went along, but to me, is infinitely nicer than using a pre-formed line bent upstand.
Work done to date includes:
erecting lots of scaffold
Stripping old sheets off - with little help from the wind
clearing the floor
digging and laying rain-water drains and power
backfilling
gravelling with 120T Type 1 and whacking (2T at a time on my trailer)
cleaning, prepping and painting
fixing new wall sheets
fixing new curved sheets
fixing the original makers name plate
make new (old style) gutter brackets
repair old sheet clamps
