Wheel exercise

[Chazza]

Hello my friends!

I set up the wheel today and decided to have a go at Exercise no. 1, as posted by Jonmar. Photo above.

Things were going well until I increased the pressure and lost control of the shape; the object being to have all four corners resting on the table.


So corner A and C have remained about 20mm off the table between them. At one stage there was far too much metal gathering on two of the edges, but I managed to get rid of it by stretching inboard.

Any idea on what I should do next? I have tried wheeling diagonally near A and C but nothing happened of any consequence,

Cheers Charlie

have you tried just to flatten the four sides by hand?

looking at the pic the 2 ends seem to have a different radius to each other, or is that just how the pic is?

not a lot of pressure is needed, technique produces better results

Thanks Neil,
I worked out what is probably the problem – forgot to anneal it!

Yes you are correct, too much pressure would not have helped, I was experimenting.

If I succeed, should I stretch along the edges to get it flat again?

That's better.

Keep up the good work Chazza. I am following your post.

Thanks Will.

I am not used to working with aluminium so I often forget about annealling. Once I did that, it was absurdly simple to get it to move where I needed it to.

Aluminium does not like to be wheeled with too much pressure all at once

Thanks Peter.

To get the panel to go flat again, I guess I should stretch the edges. Is there any particular pattern that I should follow?
