Hi all,
I want to joggle the edge of a hole in an aluminum sheet so that I can fit a flush fitting panel held in with dutz or simpler fasteners. does any one
have a guide to Joggling or can you recommend a tool? I would like the corners to be radiused, how do you do that?
have just seen them but i'm not sure if they can go round a radius conner.
No maybe not
How about cutting a hole in a piece of ply wood the shape you want then lay and clamp the alloy on i t.
then tap it to shape
After that cut the center out to leave a flange for the clips
You may have to practice this
Hope you know what i mean

For awkward shapes in steel panels I have used a shaped backing piece and then, using an old screwdriver with the end rounded off slightly, just hammered the shape into the panel. It's best to go gently and take a few passes to get the folds fully formed or you risk ripping the metal.
I'd try making a hardboard male and female template that fit together with a gap and hammering them together on a backing surface. Cut the hole
first, but leave a generous flange to be trimmed
after.
Would work best if you could improvise a press arrangment.
Cheers

Put a countersunk set screw in the hole and a few big washers on the other side followed by some smaller washers to grip to. Tighten a nut on the back side and the head should countersink the hole.
Good advice from the above. For a small hole a Joddler would not work but a simple press tool certainly would. If you have a number of holes all the
same to do, it's might be worth making up as tool. Try to ensure that the aluminium is clamped top and bottom so that the panel will not be
damaged.

Just a few more details of the tool I used. It's called a Rolastep and available from LB Restorations. Link:

It is easy to put a stepped flange round a radius but I'm not sure if the flange would be wide enough for a Dzus fixing. I used M5 rivnuts.
Oh, I've just read that it can do a 12mm or 17mm flange so this should be ideal.
A couple of pics below.

You want a rolastep joggler, kindof expensive for a one off job though.

You should be able to achieve this using simple male/female wooden forms that you can clamp the sheet between. For making these a wood router would be a useful tool to own, but not completely necessary as you can build up forms from multiple thin sheets of material.
