Threading a steerer tube

I've picked up a cheap '97 Judy with a 1 inch (!) ahead steerer tube.

Miraculously the elastomers are OK and the rest of the internals (bar the springs) also look good,
so Im planning to fit them to my bontrager which has a threaded headset.

Any issues with adding threads to the steerer or should I just go the whole hog and get an aheadset + stem?

I know the user manual says not to, but its only going to be used for pootles / very mild off road.

Does anyone know a place around manchester/lancashire that could do the work for me?
 
Re:

Shouldn’t be an issue with threading a steerer, used to be a very standard thing to do.
Make sure the steerer isn’t butted as some higher end ones were to reduce weight. This would mean the wall thickness could be too thin to cope with the threading.
Also make sure the internal diameter is correct for using a quill stem. This can vary slightly with ahead steerers as the only important diameter is the external when using ahead.
Finally cutting a new thread on an ahead steerer is tougher than chasing existing threads and especially so when the steerer is press-fit in a crown. Best bet is either a frame builder or an engineering company. People like Steve Goff in Lancashire, bob Jackson in Leeds, Peter butterfield (in the old Neil Orrell shop, I think) in manchester

Thanks!

Didn't know about butterfield cycles - but they are just off my route into work so I'll give them a try.
