You can do everything you need with a jigsaw.

Now if you want to get into some precision and speed then you need to look at adding at least a circular saw, and then again with the addition of a table saw. At this point you should add a router too for holes.

 

I went out and got a cheap table saw from canadian tire, 100 loonies for it. Ive only used it for making one sub box, but im glad i still got it, saved me alot of cutting time

 

I have to agree allthough with some practice you can get a very straight cut with a sircular saw, I use them all the time but you will always get a straighter cut and better seal with a table saw.

it is good to have an extra person there to help support the MDF as your running it through the table saw though.

 

or you can just get home depot or rona to cut it for you. Last time I was there, the first five cuts are free, then 50 cents per cut after that. If it's a simple box get them to do it. All you have to do is figure out the cuts on a piece of paper in order to minimize the number of cuts.

 

ya but the shops ya buy the wood from cuts them short or cuts them too long - that has happen to me many times so i just cut it myself with a jgsaw

 

Use a chain saw LOL. I use a circular saw, also known as a skilsaw (the ones with a laser guide are nice to keep the lines str8) and a jig to cut out my speaker hole/s.

 

Skill saw for me and to do the odd trim with a jig saw. A dremell tool works for holes too. A table saw would be nice but there is no room in my garage for that.
