    Threads on a threadless steerer?

    The GF hasn't completely rejected the SS I cobbled together for her, but the rigid fork seems to be beating her hands up. I've got an old Duke C with the same steerer diameter as what's on there now, and I'd really like to avoid adding to my obsolete bike parts collection by using the existing headset and stem. Are there any significant safety issues with regard to simply taking a 1.125 X 26 die and cutting threads on the Duke's steerer? The wall thickness is identical on both forks' steerers.
    Also, the streets are full of horizontal dropouts...

    Find some cutting fluid and someone with Popeye's arms and it can be done. A cheap thredless headset and stem are easier though.

    Be careful about doing this, not all threadless forks can be threaded. I forget the minimum wall thickness, but if the steerer is steel, not butted and thick enough you can probably thread it. I would find a local frame shop and give them $20+6 pack or something. Personally what G-reg says is the much safer way IMO.
