@M_V - Thanks for the tips on cleaning out the tubing. There's been no overtigthening, top of the ST is fine. I checked for burrs etc at the tube joints when I first noticed the issues, and all seems smooth.
In good light i can see the top layer of Alu has corroded a little further down the tube, and the tubing looks straight, so hopefully a small amount of corrosion is the only issue...
Almost all parts are now on their way. still searching for a decent-ish carbon post and a set of brakes- preferably Shimano with proper brake shoes.
Currently the entire build should come in a bit north of £250
Thanks for the advice all
