Folding edges
Been trying to work out what tool I need to fold metal over on itself, similar to a tin top car door for example. Been looking at Joddlers/jogglers
(depends how you want to spell it) but they put an edge on to make butt welds neater. Can anyone here tell me what the gizmo is and where to get one
from?

A joddler gives a step so good for overlapping joints, this tool wouldn't fold metal back on itself. You porbably need a metal folder.
I have in the past clamped the metal to a solid piece of angle and a thick metal ruller and folded the metal over this

A metal folder costing about £50 will do right angles bends up to 24" in length followed by using a door skinning tool to fold the metal over
itself or very careful use of a hammer and dollie

What you are tying to do is called a "dutch bend" , if thats any help in your research

You can do it quickly. You can do it cheap. You can do it right. – Pick any two.

This another operation that can be carried out without the need of a folder or specialised equipment.
I was just going to explain how to do it but if I've got time I'll take a few pics which are worth a 1000 words and hopefully they will do
the explaining for me. It's very straightforward and with a bit of care a perfect safe-edge can be formed every time.

Okay, here are a few pics as promised.
One thing I would pass on it the advice given to me by the great Saint Trev D, "It's only a piece of metal, don't be afraid of
it". Wise words.

Hi Mike, thank you for your interest. It's important to mark your line with a pencil Scoring is a big no no as this causes a risk of cracking.
When you fold along the line this is known as "Breaking the line". So once you've achieved a nice sharp right angle, turn the job
over and clamp it so that it won't move. With your trusty block of wood gently and evenly tap the angle over and it will bend on the line. The
main thing is to use gentle taps and not try to bend it too far all in one go and a reasonably long piece of wood to avoid local damage. It
won't take long to fold it back onto itself and you'll have a really tidy edge. This is called a "Safe Edge".
It is also possible to go round corners again without the need of anything more sophisticated than a hammer and weight.
