Thanks for the thread. I hadn't really put much thought into the seat stays being a source of interference until now. I'll keep an eye out for that on frames in the future.
The easy way to bend them out is to install a bare axle of the same spacing and slip a compact car jack between the stays.
The axle will hold the rear in perfect alignment and concentrates the bend where you need it.
I flip the jack as needed to keep both sides the same.(some jacks will bend better one way than the other)
Easy peasy and it doesn't cost a dime if you have a junk rim or axle and a jack.
It won't hurt the frame unless you bend it WAY too much or buckle the frame. Use a sheet of wood or something that spreads the load to cushion the contact point if your jack tries to make a dent in the tubing instead of bending the frame rail smoothly.
If more is better, then too much is just enough.
If you can't afford it, build it yourself.
