Right, I have arranged to have two forks lengthened and threaded to fit this frame, the black ones from retrobikeguy and some plain PACE RC36. I'd quite like to run this hardtail as I already have a fully rigid pioneer. That way I can justify, to myself anyway, having another. I appreciate it's not exactly going to please the purists with a V brake on the front and possibly rear, probably later XT all over it but I'll do my best to keep it tasteful.

All kit will be black. Still undecided as to frame colour. I think one light and bright would be nice, perhaps a top to bottom fade?

That will be way into the future. First it will be built and ridden in current glorious golden garb before I invest in paint.

Oh! A bike thread! Nearly missed this one...
May I suggest you possibly consider BJ’s flamboyant red over super fine silver? In the sunshine it truly is dazzling....
Here’s my ‘51 Olympic Sprint..... although the photo was taken indoors so it really doesn’t do it justice...

And of course once you’ve moved to Yorkshire, a trip down to Leeds to meet the mighty Donald and look at all his shines options wouldn’t be too much of a stretch now would it?

Would it be wrong...……….

to put an RC36 on this? :)

Would it mess with the geometry?

And those handlebars look low enough to take the skin off your knuckles as your hands scrape along the road!

Not too far from the truth...but done now:

Firstly the Pace Steerer that was too short:
Looking for 216 + the 30mm for the crown:

Simple enough, no welding or brazing involved...just find a 1" steerer that's the right sort of (long) length:

Onto the lathe to put the circlip groove in the bottom end:

Mill the slot for the tabbed headset washer:

File off any burrs on the milled slot and Bob's your uncle. :-)

All the best,

And after a short intermission for refreshments:

The unicrown fork:

Again, too short in the steerer, needs to be 216mm:

Cut off the old top section at a point that isn't into the internal butt near the crown, or too far up that it will interfere with the insertion of the stem quill...In this case around 80mm from the crown race.
Cut a 40mm long 22.2 OD tube as an internal shim:

Cut a new top section to give the required length:

Cross drill the fork and top sections to give viewing portholes to check brass penetration:

Braze the internal shim int the fork, clean up, then braze the top section onto the fork, sweating the brass out from a ring of brazing rod inserted inside above the shim:
