Alright thanks for your feedback guys. I've started on sawing the wood so it will be a bit thinner. I'm using that KERF method that @Bizman62 said. But wow, this takes a long time I'm working on my arm muscles. I've made some mistake by cutting in the wood too deep. I guess I can fix that with my (hand) planer tool.

Thank you @Bizman62 that seems logical. I just need to buy that handsaw tomorrow

I have a big wooden block that is about 9 cm thick, that's about 3.54 inches. I need to reduce it to 6 cm (2.36 inches). What type of saw or machine do I need to have? Here is a photo of the wooden block: https://imgur.com/a/WhyYA5J I need to reduce the thickness otherwise the guitar body will be too thick. The full size of this block will be: Height: 45 cm (17.72 inches) Width: 34 cm (13.39 inches) Depth: 6 cm (2.36 inches) Thanks for your help. Btw, this will be my first build ever :-)
