I've had no luck finding a local shop willing to use their die, (apparently some tools are now only for show, or the last qualified mechanic has left their building) plus more than one shop did it but with such horrific results I wish I hadn't found them.
Next step is to have one of those Park SG-1 saw guides (or the more $$ SG-6 or 7 models) and a nice sharp hacksaw blade.
Easy-peasy, but might have to also extend the slot for washer tab
Funny, I have threaded so many forks, including at the local coop just recently. It is strange that someone managed to screw that up for you. It is neither difficult nor requires a particular skillset.
Long before Park steerer cutters, we used an old steel headset part to cut against. Not only was the cut square, but threading the part back off cleaned up the thread ends.
It is quite possible that I just spent all my bike mechanic shop time among highly skilled and well equipped people, but it really amazes me sometimes how little luck folks have getting a standard bike mechanic job done.
