RE: Do I really need these?
Well Know The other fellas have told you what you need as far as tools.
How about the fun stuff. Get the kit. Set it on a table and open the box. Now take 3 or 4 real deep breath's of air and let them out slow & relax Read the instruction book 3 or 4 times don't try to commit it to memory just get a feel for what's first and what's next. This is a great kit, and great plans, easy to build, and from the all of them I've built the parts fit well. If you get to a spot your not sure of check the instruction's if they don't answer your question feel free to come back here. Look at the replies you've gotten already we'll all be glad to help. Relax, take your time, and have fun.
Right fellas
