Well, that was interesting...

... or not, as the case may be.

Today I was furtling around with the saddle height to take advantage of the Far East comfy saddle and realised that for years I'd been riding it (the old one) just a bit low (I followed some of the late Sheldon Brown's advice to set it higher and higher until it was too high, then drop it until it was right). That seemed to do the trick, but then I wanted the bars a bit higher - problem was, the stem is a quill type and it's out at the maximum safe limit.
Then I recalled that a couple of years ago I bought a set of Marzocchi Bomber Z2 forks, with the intention of using them on a NOS ally frame I'd picked up. It never happened, for various reasons, and the project is a back-burner one for the moment. Problem is, the Claud Butler steerer tube diameter is 1" and I was damn sure the MB forks had an 1 1/8" steerer tube. Turned out I was wrong - the steerer tube supplied is a 1" one and there are two of them of differing lengths - problem is, the only fly in the ointment, is they are threadless. Buggre.
Hohum, more expense - looks like either I can thread the long one and that will give me sufficient height with the quill stem, or I can use it threadless with a new headset and new stem with sufficient rise on it.

Has anyone any experience of threading steerer tubes? I've done plenty of more mundane threading, but never one of these.

A bit of an update for those who might be riveted to their seats with an.....tici... pation...

I decided it was daft to attempt to cut nearly three inches of thread, so went for a new 1" threadless headset. OK, that means I can't use the old quill stem - new stem ordered. Of course, I need a stem shim - ordered. The new stem is the highest one I could find at a decent price, but it's not high enough - extension piece ordered. Hmm... brakes and mudguard - well, the mudguard can be left until later, it's not insurmountable, but the brakes are a vital part. The old cantilever brakes are actuated by a naked drop cable from the old stem, which won't be there any more. A crown-mounted cable bracket is a possibility but I didn't like the look of it at all - looks to me as if it would flex or snap eventually - buggerit, V-brakes ordered.
Of course, the old brake cable won't do at all, so cable ordered. I also ordered a set of higher and swept bars just in case. Most of this was NOS on clearance, so it wasn't as bad as it could have been.
I consider I got away lightly by spending just shy of a hundred quid today on bits. It'll be nice to have a set of Bombers on the front, though.

I just fitted a quil extender to my Evans MTB conversion, the front brake cable comes out of the stem like yours and the thing took 5 mins to fit and I could if I wanted lift the bars to near chest height:eek:

You can just about see the existing quil in the top of the extender IMG_0161.jpg photo - david chilvers photos at pbase.com

If I wanted to keep the rigid forks, that's all I needed to do. Of course, if I could have found a 1" threaded head tube long enough, that's all I really needed to fit the Bombers, but they're now like hen's teeth.
No matter, none of the spare bits will go to waste - there's always another project.

Stap me vitals, Snowy, what a difference!
I decided to ignore the back pain today and carry on with the Bomber fork conversion, eventually finishing it at 10pm. Just a quicky up the road and back (also giving me a chance to try out a pair of cheapy 5W LED lamps), but I'm impressed by how well it all works.
I've now got decent front suspension, a riding position that suits me much better, and a set of brakes that would have me over the bars. I wonder if the proper V-brake lever is a bit more progressive in its application - the Avid brakes and the old lever make for a spongy action which is a bit sudden in bite.
