I usually use gimp to resize, it's free and works on most computers.
The forum used to have a plugin to downsize, but I guess the most recent software change punted that.

I know people that volunteer at velodromes, and they are always begging for bikes, so I'm sure this will be really appreciated.

I have a bender like yours, but not as nice. The first blade I bent on it was a disaster. I'm making a die for my Diacro, it's on the list of projects.
