I cold set my daughters 2003 Fuji Touring to 135mm spacing using hardware parts as suggested by RJ the Bike Guy with some of my own changes.

The tools are made from all-thread, nuts, bolts, and washers.



You widen the spreader (sorry for the photo) with a wrench to the width you need (and a little over). I actually over spread it and had to move it back a little. It was simple and a whole lot more elegant than the 2x4.



I made an aligner that will easily bend the drop outs back to parallel



And then checked the alignment with the string method.



Easy peasy.
