Re: pic: Sheetmetal 6WD

1/4" Bend Radius? Why so big?
Our sheet metal shop uses the following:

0.125" 5052 Alum = 0.048" Bend Radius
0.090" 5052 Alum = 0.032" Bend Radius
0.063" 5052 Alum = 0.032" Bend Radius

Talk to a local sheet-metal shop and find out what their standards are.

They can probably also give you K-factor or Bend Deduction data for each material. For those that don't know, these are basically measurements of how much the material will stretch when it is bent and can be programmed into the CAD program so when the material is flattened and exported this is taken into account -- but this is all a bit off topic.
