tlehnhaeuser Posted October 30, 2019 Share Posted October 30, 2019 I think the Miter Flange is correct, however I noticed your "sections" are not the same sizes. Is that what you want? Quote Link to comment Share on other sites More sharing options...
jolizon590016 Posted October 30, 2019 Author Share Posted October 30, 2019 I has a problem when unfolded by using a reverse miter flange. I split it into 2. Quote Link to comment Share on other sites More sharing options...
rsaucier Posted October 30, 2019 Share Posted October 30, 2019 The miter flange does not work in this case because a flat pattern will have overlapping metal and can not be cut. This is how I would cap it if I were building it. Sheet Metal Part87rj.ics Quote Link to comment Share on other sites More sharing options...
rsaucier Posted October 30, 2019 Share Posted October 30, 2019 I hope I explain this well but the reason a revers miter does not work is that you are folding the metal back up. So the mitered material is actually overlapping in the flat pattern and can not be made into a flat pattern or cut. Quote Link to comment Share on other sites More sharing options...
rsaucier Posted October 30, 2019 Share Posted October 30, 2019 Sheet Metal Part87rj.icsI revised it so it closed up the gap a little better on the top edge. Quote Link to comment Share on other sites More sharing options...

HDEAR Posted November 5, 2019 Share Posted November 5, 2019 (edited) Hi Joseph. You're on a hiding to nothing trying to do that 20 degree fold with the other folds. I'd make it in 2 pieces ( identical end conditions to laser cut ) and weld it. 2mm Aluminium is OK to weld. Note the use of bends without length and add stock - it's so versatile. Filler pieces are a PITA first of all to make, second of all to weld. - that's why I wouldn't do it that way - I'm concerned about the 0.8mm inside radius for 2mm Aluminium. That's cracking territory. 2 piece Sheet Metal Part87x.ics Edited November 5, 2019 by HDEAR 1 Quote Link to comment Share on other sites More sharing options...
