I have used my SUV to flatten down frames before, I dunno how doable a set of forks would be doing that, and of course its not the safest/smartest thing to do......but I am a born and bred Flori-duh redneck so its all good :wink:
depending on what kind of forks they are and where the actual bend is you may be able to work it a little with a long cheater bar in a bench vise or maybe head out to the truck and utilize the the receiver hitch hole.
I keep an old handle form a broken hydraulic floor jack in my toolbox, makes for a great cheater bar.
you just have to be gentle at first sort if test the waters to make sure your not going to ding into the tubing or if it will make it bend in another spot causing an S or something.
