Are there any 'typical' bikes you see at Glasgow?
Dolans. DF4s are exceptionally popular and not just with sprinters.
Cervelos are quite popular too, obviously coming with a price tag but the pursuiters seem to like them, probably because of how aero they are.

Is that brass you've used to braze in the stainless tube? I thought stainless > non stainless had to be done with silver?
Also, what spec of tube did you use? I'm thinking about running a tube through the toptube of the frame I'm building just now for brake cable routing.

But Sram...

My man!
Will you replace the headtube entirely or just add onto the top of it?

Unfortunately the rear spacing is 135 which I guess will limit me a little?
Not really. There're plenty of nice mtb hubs out there. It was just if it'd been 130mm then a road hub would have been a good fit. If you want a singlespeed specific hub then theres Hope and King cassette hubs or ton's for screw on freewheels, Paul, Surly, Spot, just depends what your budget it.

I'm pretty certain our coaches have stopped them going on on the grounds of them being too treaded on the shoulder.

Maybe I should just get a pair of the rigid zaffiro slicks for now?
Best bang for your buck. They do need a bit more prepping than they used to, clean with spirits, bit of a scuff up with sandpaper and snip/pull the little mold 'pubes' off on the right hand side so they don't get under your contact patch and roll around when you're going slow.

When I was doing tig at the nightclass I did I was always thinking I'd like to try one of those big cups you see a lot of tig welders using. I reckoned you could rest the cup on the metal and having that sort of pivot point would make it easier to keep the tungsten out the puddle.

So, oxy propane peeps, what sort of supply pressure settings and flame sizes are you using? Oh and nozzle/tip sizes too?
I've been using the smaller of the tips that came with the Weld-Equip kit, think its a #3, I've been setting my regulators to give me between 1 and 2 bar supply pressure and I've been using a flame that's probably about 10-15mm inner cone with the feathery outer flame around it.
Matt from Rothair Cycles had me over to his workshop yesterday for a wee fillet lesson and he has his (oxy/acet) torch set up so differently.
He was using a higher supply pressure, 4 bar I think, a #1 tip (though he did say he'd sometimes use a larger tip for fillets) and an absolutely tiny flame, like 3mm of inner cone probably. His torch was almost silent whereas mine is roaring when I'm using it.
I did a fillet at Matt's last night and while there was still plenty to be working on, it was the neatest joint I've made yet by quite a margin.
I'm hoping I can get a couple practice miters filed while I'm at work today and can have a bash at brazing them with my torch set up more like his tonight but I'm worried that I'll not be able to replicate what I did last night with my cooler oxy/pro flame.
I also found it interesting last night that Matt purges his pipes at the end of a brazing session but doesn't touch his regulators. I'm sure I'd read that it was good practice to back the ajusters off till there was no resistance felt so I've been doing this after every session. Matt also has a day job at Shand by the way so I presume they must be treating their regulators similarly, makes me think what I'm doing is a bit ott.
A list isn't really a good idea, there are lists for tyres but they constantly become outdated and then you get the 'But it looks just like XXXX which is on the list" argument.
A specification would be better in which case, 11" bb height, no brazeons and track ends will about do it. You probably want 73 deg or steeper headangle. Similar on the seat tube. UCI compliance is a thing but it doesn't really sound like you're at that stage as yet.
