1" Threaded again?

1" Threaded again?
I know this has been covered in the past, but current information on this is hard to come by. I have an old Bianchi Touring frame that I am trying to ressurect but the fork was subject to recall and replacements are no longer available. Can't seem to find a 190-200mm threaded fork with canti's. I could go 1" threadless but that takes away from the nastalgia of it. Any help C&V guys?
Thanks

Sounds interesting. How old is the frame? ... Perhaps searches for "Cyclo-cross" frames and forks would help broaden your options. "SURLY" makes a 1" threadless "Cross-Check" fork which looks pretty nice. It has a traditional sloping fork crown - which would look very good on an older bike... and especially vintage Italian. 300 mm steering tube length. I wonder if this could simply be cut to the needed length and then threaded with a fork threading die?

Here is a link to one company offering the Surly fork ... $94

I am not positive whether the outer diameters of a 1" threaded and 1" thread-less steering tube are exactly the same, but I really do think it could be threaded for you to maintain the traditional look of the bike. _ Park and VAR Tools both make [made?] tools for this, and I suspect any frame builder could do the job - which should take only a few minutes of labor. _ Possibly even a local bike shop... one with an experienced old-time mechanic.
Failing this, Tange still makes Threaded 1" replacement "Hybrid" CroMoly forks for 700c wheels... with canti bosses and eyelets ... and with fully chromed finish. _ On the down side, these are the cheap looking modern unicrown wishbone-look forks.
I have a VAR threader myself
... but, unfortunately only a die for French threaded steerers.
Sorry.

Thanks. Upon some research, it seems that threading an unthreaded fork is a major pna. Guess I'm going threadless although I hate the look. Unless there are some framebuilders looking in that'll offer some service...

I have threaded steer tubes before. Its not so much a pain in the ass as much as
it is an exercise in patience. Cut it to length leaving at little extra, and use lots
of cutting oil. LOTS OF CUTTING OIL!!! And to slow and take your time. When
you are unthreading the cutting die use even more oil and make sure you are
not just spinning the die around (this sucks royally). Use slight upward pressure
to make sure.

Nothing special, but I know where a 700 Cyclocross canti fork is, Tange and cheap. Also a unicrown, but is threaded and may be the correct length. I haven't measured it, but I can tomorrow morning.,,,,BD
I know, not Bianchi pretty, but will do the job.

I've got a Centurion Pro Tour 15 with a fork about that size (~8" of steer tube). Unfortunately, the bike was in a front end collision that put a slight bulge in the top and down tubes. I haven't taken the fork out to check it but it looks OK (It's still in the bike, turns a bit tight). It's a steel fork, of course, so it could be repaired if needed. It's a real touring frame - and a nice one, shame about the frame damage - so the fork has all the nice touring braze ons. PM me if you're interested.
