How to make a sheet metal box with curved edges.

2008 includes a new corner weld that cleans up sheet metal. Step 1 is to design the corners like shown in above image. Repeat steps 1 5 for the opposite side of your box. Once all of the squares are cut out you ll be left with the four flaps.

Use your bending leaf handles to slowly fold your sides and tabs to 90 degrees. So mark out two 4 x 3 1 2 sections of sheet metal and cut it in the metal shear. The sides will be 3 x 3 but we add 1 2 tabs on three sides. It is easier to cut off a 4 x 12 strip if you have a 12 x 12 sheet first then cut two 3 1 2 pieces from that strip.

Minimise the gap setting to the least value allowed. It s suppressed in the flat pattern. You ll be bending over the edges of these flaps to make smooth edges for the top of the box. Step 4 grind flush.

Rounding metal with the bevel heads from beveltools ensure a smooth and consistent rounded edge on sheet plate pipe and hole. Lower the clamping bar handle down to clamp your metal into place. You can create the perfect uniform radius with these bevel heads. Step 2 is to tack weld the cornerfill into place.

What you can t do is unfold it. Return your bending leaf to neutral position and lift up your teeth to remove your bent metal. This is how easy it is to make a rounded edge on metal. Step 3 weld all seams.

This will create a lip. We start the box by making its sides. Model a baseflange with the radius down to the bare minimum. Now if you make the box by creating an extruded rectangle add fillets to all of the edges and corners and then shell the thing outward you can make that into a sheetmetal and add louvers and ports and stuff like that.
