Steerer threading....

[konatime]

Anyone know where i can have a 1-1/8 steerer threaded in the Gtr M/c/Derbyshire areas.

Vernon Barker Cycles, Dronfield? I think they still actually BUILD custom frames etc so I imagine can "thread". Never used them, but once asked a few Qs re frame alterations and they were very helpful.

Cheers Dave....i've spoke to Vernon, he did a little bit of work for me last year (had a couple of nice vintage repairs booked in-he sprays and repairs titm also), he's only got the 1-inch cutter and after phoning round i'm running out of options.

Can anyone tell me the thread count i should be seeking please? (i forgot to ask Vern ..i'll be marrying to a Mavic 316 headsets...if thats somehow specific.

Have you tried Halfords? I know some don't rate them highly but a guy in my local branch cut and threaded some Manitou 3's for me and did a great job and reasonably priced too.

Thanks for the heads-up Pops (no ...i'd not thought of them).

Anybody else any suggestions/thread count?

That's got the potential to go very wrong. I get that service and quality can vary in such big chains, varying, probably, from very good to very poor.

Problem is, that type of task requires quality be very good, and that level is not ubiquitous, probably quite rare, and it tends to only be confirmed when it's too late.

I KNEW that some French threading is non-standard - but seems that by time 1 1/8th emerged will have come into line:

"Headsets

Many French bikes sold before the late 1970s used the now-obsolete French headset threading:

25 mm x 1mm (0.984" x 25.4 TPI)

instead of the ISO standard threading:

1" x 24 TPI (25.4 mm x 1.06 mm)

For more details of headset dimensions, see the Headset entry of my Bicycle Glossary"

When I phoned and asked the 5 shops local to me whether they could cut some thread on a 1" steerer I got a lot of ums and ahs and tales of "when this was all fields".

The tool seems to be available - at 80-100 quid. BUT I suspect that in other than highly skilled hands really only suited to EXTENDING an existing threading. Presumably manufacturers do not use a hand held (single cutter?) die. Certainly even 40 years ago in th'engineering the taps I used were powered (and easily snapped when one wanted a break on nights!).

Thanks for all snippets Dave, bizarrely i'm familiar with cutting threads have installed plenty of conduit in me time (can't recall cocking many), now i know the thread count i'll be leaning on some old friends.
