I agree with Rolf here. The thought of doing the joint is worse than actually doing it. It's a relatively simple task to make a strong scarf joint. The key points are:

1. Make sure there is enough 'meat' in the joint. 8:1 is the minimum but go to 10:1 if you can.
2. Ensure that the mating faces are flat and the same angle
3. Ensure that the mating faces are free from dust and debris
4. Use a good quality stiff epoxy, correctly mixed by measuring (I include colloidal silica in the mix).
5. Don't use excessive pressure when joining the pieces so that they creep. Fixing to a bench with some way of gripping/holding the workpiece rather than the joint is good. You can then use light pressure to hold the vjoint closed.

Once done and cured, it's surprising just how much bending a scarf joint can take. On some of my early 2mm and 3mm test pieces it was the ply that failed a distance away from the joint rather than the joint!
