I have a request for straps, which brings the whole question of bending metal to the fore.
@luc.onthego found a great video on this mentioned at:
and I hope @themillertree will chime in.
Thus far I’ve been quite simplistic in my handling of this:
- cut off at the desired angles
- “bend” at the midline of the material
- round off the outside edge with a cylinder
and my question is — what are the calculations and needed parameters for this?
Assuming one wants:
(actually cut out of angled stock, but you get the picture)
then what is the profile one needs to cut?
It can’t be the simplistic:
but how would it deviate from the:
which I described above and is what I am currently modeling?
I’m thinking as a first approximation rather than halving the thickness I divide it into thirds and round the bottom of the channel (hey! I have a BitSetter, I should use it, right?):
which when zoomed in is:
Anyone have some useful guidelines, links, or numbers?
