Bend in rear frame stay to accept singlespeed?

Searched the forums but coundn't find an answer.

I have an old cheap road steel bike with a 5-speed rear cassette, and found a bike with a 3-speed internal hub rear wheel which is narrower by a good 1cm - 1.5cm.

Thing is it was easy to screw the thinner wheel to the wider seatstays (and no strong force was needed), but I'm not sure if the frame is now structurally integral, and will it hold even if those rear tubes are at a slight angle.

The bike is very heavy (37lbs) so I'm hoping that the frame is pretty tough and will be able to stand such a bend.

PS- Even so, I am just so excited to finally have a bike without a rear cassette. Its like a dream come true (even though the bikes a piece of ****e.)

You're talking about frame spacing: <http://sheldonbrown.com/frame-spacing.html>

With a steel frame, it should be possible to make the change safely, though doing it more deliberately may be slightly better/safer way than just screwing the wheel in.

It would be better, assuming the axle is long enough, to add spacer washers to the axle inboard of the fork ends.
