With the spars front and back complete, its now time to glue them together. The way that I thought would be best to approach it is to glue the widest two ribs together. This hopefully will ensure once set that I can maintain straightness and squareness.

Using a spirit level, laser level, trammel points and a tape measure I got the spars within .5mm comparing opposite corners to opposite corners, whilst keeping everything vertical where required. Pics show the clamps, laser level lines and centre lines of spars. Good to get this job done. No going back if I got it wrong!!
