Here's a simple design for a fork blade bender. This is used to bend or rake the legs for bicycle forks. It could also be used to put gradual bends in metal tubing for other uses.
It can be made with not much more than than an Oxy-acetylene torch, hacksaw, and drill press. The materials are probably all available at your local Big Box hardware store, though you should see if you could buy the angle iron as cutoff remnants from your local steel supplier, as it will be a lot cheaper.

I get the issue about bending the fork Blade.
But I cannot understand, How can you reduce the tube diameter at the end of the tube???????.
Thanks
Its tappered tube, the only thing that you do it bend it.
I Say that, cuz I'm working on a personal project "Penny farthing".
The Fork Blade of a Penny farthing doesnt have the rake like a normal bike.
But It also have tappered end at the end of the Tube.
Then, I'll buy square tube for the beginning of tube and weld a tappered tube at the end.
Thanks man!!!!
