Open Source Bender Update
A Quick update for you, to show a bit more versatility
See the pic of the bender first and note the step in the angle
Then substitute that step for the one that I have shown below when creating a rib in a panel, such as a floor pan or similar
Then you need these tools, I use a big mash hammer and a 2" chisel, the weight of this hammer means you don't have to hit it too hard, and the 2" chisel makes quick progress across the sheet, obviously you can use a smaller chisel for more detailed areas or curves.
The Chisel has a slight radius on the top, we are only trying to bend the metal not cut through it
Then lay your metal over the top angle as shown
I am sure you can guess what you do next, but not too hard, and work along the piece, you are not trying to form the full depth in 1 hit
Then back along a couple more times
If you need the rib to have more definition, then angle the chisel more tightly into the angle
And then turn the piece over and add definition from the other side, this might need 2 or 3 turns dependant on definition
And here is a full 8mm rib, each bend at 90 degrees
So now just turn it round and over and create the other side, at whatever width you want
And repeat as before
This time I am just driving the chisel straight down for a more gently formed rib
And here we have this side, I have purposely done them differently so that you can see what can be achieved
Now say that you wanted a shallower rib in the middle of the panel that did not go right to the end
Position as before, but only hit up to where you want it to stop, I have also not driven it right down on the base angle, but you could just use a thinner top angle, to achieve the same affect
that gives you this, dependant on how near the end of the sheet you are you could end up with some puckering like this
And dependant on what finish detail you want you can just dress it with the hammer
This can give a more gradual stop end
Or use the chisel to create a more flat stop end
And to add more definition, use a bit of 10mm dia bar to dress from the inside
Which should leave you with this
