First of all, I am a new this form and it has been more then twenty years since I last built a Guillow's product. I like this forum because it features a how to philosophy and the end products are absolutely amazing. All the above has motivated me to build a Spitfire(500).
I am using a Magna-Board to help with the construction. The magnets are stong and they will hold the pieces down and then some. Also, they are great for making sure your forms are straight and true. It's like having a third hand. I am notching the forms with The Notcher. It does a great job.

I am using a home made jig to help true the fuselage:
