Cow horns would probably look great Wish I still had a set !!!

Well the BBs are well and truly stuck, been soaking in cola for 36 hours and still rock solid

Try fire - use a blow torch to heat the BB axle, keeping the flame well away from the paint, then when its nice and hot spray water, lube etc to rapidly cool it . This may crack the corrosion between the BB shell and BB itself. We do this on low end bikes where I volunteer and it works often enough to be a viable strategy

I wouldn't like to do this on anything nice though,.

Doesn't look very ratty to me! The decals are still on and the paint looks half decent (although it isn't my cup of tea). I thought the whole idea was to make it look scruffy enough that no bike thief would go near it? In my manor, that would quickly get nicked.
Patience and hydrocarbon solvents is the name of the game when it comes to freeing seized parts. If I need to leave something soaking submerged in solvent I tend to use diesel, sometimes mixed with ATF transmission oil if I've got any to hand. I've got pistons out of old engines that have been stored in damp conditions for years using that mixture. I've left stuff soaking or kept reapplying more solvent for weeks in some cases, but eventually it always comes unstuck.

Took it to local halfords as i know the mechanic is a good un , £10 to get the old one out .Worth it to me to save much cussing and he did say he used a big lever to get it out , they do have a desk mounted vice/ workstand though whereas my lidl stand want holding it tight enough as i was applying leverage and beding my tools and broke the little steadying rod thing with torque i was putting through the frame.

Nice ride!

All done
total cost of the build is £32
Needs a new rear mudgaurd as the back one has a chunk out and doesn't hold its shape so it rubs but otherwise its good to go

Test ride to work last night, pretty impressed as it didnt miss a beat and apart from minor adjustment to fit it feels fine.
