Hi im new the the sport /hobby myself but im in the process of building two of my own and you will need a drill with wood bits, a router and some sand paper mainly . Keep all your basic hand tools near by though, like screwdrivers, chisels and so on.but you will need some nice strong adhesive and some clamps for the initial bonding of your wood of choice, I found a jigsaw was a great way to get my shape and handle correct but I am using the wooden american method, I would also adise that you buy in your trigger mechanism as making one as a novice is not a good plan. Talking from experience, hope thats some basics covered, a more experienced member will hopefully get back to you soon.
