G Day Charlie.
I definitely cant fold that close with mine, as it doesn't have the clamp capacity, even when using spaces under the clamp bar. I will post a pic of mine to show the difference on Tuesday when I go back to work. Thanks for the test demo, as it proves that my machine is not up to scratch of the new generation. Cheers John

I think you could clamp on 1/8" of material and bend it. All depends on its length and thinckness. B

Images of my Magna Bender.
Must be 1st generation. ResMagna.jpg Magna Resi.jpg ResizeMagna.jpg I may have to update, if the new can bend that close now. Thanks for the update.

The Magnabend is a DC (direct current) magnet and therefore will not heat aluminiun via the eddy current effect.
It will of course heat the metal workpiece a little by direct thermal contact if the magnet itself is already hot.

Thanks for the images of your Magnabend machine. Yes, that is definitely a first generation model. The later machines didn't really improve the minimum distance between reverse bends but they did employ a stronger (E-section) design, which pushed the maximum thickness capacity from 1.2mm to 1.6mm. I recently posted some information on my website which showed how to get closer reverse bends. See here: http://www.aaybee.com.au/Magnabend/M...erseBendsClose.

Thanks for your post and the picture is very informative. You mention that you did 3 of the folds on your Magnabend and the 4th one by hand. Since the profile is a tapered "top-hat" you could probably do all 4 bends on your Magnabend, although possibly the sides of the top-hat may have to have a little more taper: Please see this section of my Magnabend website: http://www.aaybee.com.au/Magnabend/M...TopHatProfiles

On my test-piece, the 4th bend opened out the angle of bend number 3; this was not desirable as the most important dimension of the rib I made, was the angle and altitude of the tapered piece. Hence the reason why I did the last bend by hand. Maybe I should try your method on a full-size piece; the material is 1.2mm gal. Cheers Charlie PS I like your website thank you for sharing!
