Project CSG

So... Some interesting things happened.

Plus points

• The repair is very, very solid.
  
• The UD layer looks great cosmetically
  
  
  

Minus points

• The tube has a bulge in it where the repair is, sits proud about 0.5mm
  
• The shrink wrap tape overly-compressed the tube deforming the shape of the top-tube where the crack had been
  
• The deformation will need to be filled and the process repeated
  
  
  

Interesting points

• The squeezed out epoxy mix hardens on the tube and is a nightmare to get off so should be wiped down whilst still dry
  
• Carbon is pretty easy to work with
  
  
  

Next steps are sanding back the repair, filling the deformation with a 2-part filler, allowing to cure and then applying a further 2 layers of carbon weave repair.

I will make thenext layer cover the crack plus 20mm and the last layer extend hugely over the crack by 100mm either side and wrap the entire tube.

Should be ok.
