It is great that you are willing to scratch build the wing! I've been using a hand coping saw on my last few projects as my electric saw is in the USA. I glue 4 rectangular pieces of balsa (at a time) together only on the edges, use a pin to transfer the rib pattern to the top one, ball point pen the pattern, and then carefully cut it out and sand to shape. I have a few sanding blocks that are quite small for the spars and turb spars. It works out okay. I am sure you will get lots of advice here, but it can be done. All it really takes is motivation and patience. Put the rib stack together when you have them all cut out and sand to make them all the same shape. Best of luck to you! The Senior Kadet is a great flying plane and you will learn a lot as you build it.
