Marc suggested softening it. This video makes it sound pretty doable. Does anyone have a torch I could use?

How would I make an adapter plate? I'm thinking that I'd need to mill out a hole in a thin block of steel for the axle and then another for a bolt sized to the current mounting piece, then bolt it together. Thoughts?

I am picturing either attaching the bracket to the bike frame not on the axle
itself, or making an adapter plate that fits onto the axle and bolts onto the
original trailer plate.  But I need to see it or see pictures.

also I have an oxy acetylene cutting torch if you really want to make the hole
bigger :)

(that would happen at my house)
