Another post got me to thinking that a lot of would be DIYers may have no idea the minimum list of tools that they either need to own or have access to. I thought I would start a list with some estimated costs and see if we can come up with a usable index. If we assume that this is for a onetime sub builder or someone who wants to build 4 of 5 speakers can we agree that you won't have to buy DeWalt or high end tools? Let's start with minimums. That way, a builder can always decide to spend more for tools. Skil Saw $45 40 tooth carbide blade $15 Clamp on edge guide $45 or home made for $10 Router... may be optional if you are painting with textured paints and you don't want to recess the drivers....ie a sub. jig saw... if you don't use a router clamps ... bar clamps run 10 to 20 each depending on length I would guess a minimum of 4 screw drivers pliers wire cutters / strippers ????
