All right, all right. I'm going up to Lake George for the week, but I will DEFIANTLY get that *&%@#!%& garage cleaned up so I'm able to get to work. 
Mike I had a feeling you were talking about your N3TLs when I read your first couple sentences
As I told Jay I plan on making some simple small speakers for my family. Kids will get an X-LS Encore and an LGK for my wife. This time I will build the cabinets before ordering the speakers and all. I'm thinking that will bring my skills up to where they need to be for the larger cabinets. That's were I got stuck (back in the day
) I wanted them to be really good, as close to perfect as possible. The veneering was going to be totally new to me and kind of intimidating. I decided that my long cuts, using a hand held circular saw weren't good enough so I got home depot to make better cuts; I started learning how to you the circle jig and then the garage started getting filled up and work and ...
I have GOT to get these things built an check 'em out!
George
George,
Man you got your own lake, how cool!!
Definitely the more you build the better you get. The N3s were my 5th build. My first build actually turned out to be a hanger queen which I used for practice. They were going to be X-LS Encores but when I glued up the main box (sides, top and bottom) they ended up out of square. Rather than throw them away I cut slightly oversize pieces for the front and back and glued them on. Then I got to practice with a flush trim bit cleaning them up.
After that, I used them to practice new cuts and/or profiles before using it on a pair of speakers. I also used them to practice applying veneer. Practicing something on scrap before doing it to the project is a very good idea.
As Jay said, a flush trim bit is your friend. I have a table saw so making straight cuts is a lot easier than with a circular saw but it is not a very high end saw. It's actually a $500 job site saw from Home Depot with minimal adjustibility. While it cuts straight, perfectly square is beyond its abilities. So I use a technique referred to as "purposefully make the mistake easiest to correct".
It goes like this: when you cut and join two pieces together, say a top and a side, one of three things will happen. (1) they will fit together perfectly; (2) the piece with the end grain will be too short or (3) the piece with the end grain will be too long.
The chance of (1) happening are slim. If (2) happens, the piece with the end grain is too short, you have to sand down the entire adjacent piece to make them flush. If (3) happens, the end grain overhangs the adjacent side a little you can easily clean it up with a flush trim bit.
So measure and cut your pieces to make sure (3) happens. The way I do this is by laying the pieces out so the top and bottom pieces overlap the side pieces. I cut the side pieces to the exact dimensions I need. I cut the top and bottom pieces to the exact depth of the box (so they match the sides) but 1/8" oversized for the width. When I glue them up I leave the top and bottom pieces about ~1/16" proud of the sides. Once the glue dries I run a flush trim bit over the edges to even the sides up. I cut the front and back pieces 1/4" oversized in both dimensions (width and height) then glue them on so they overhang the box ~1/8" on all four sides. Then I use the flush trim bit to clean everything up.
When I built out the networks for the N3s I used Sonicaps, Mills resistors, and platinum by-pass caps. I went a little overboard with the Platinums putting them on all the caps in both the tweeter and woofer circuits but I like the results so I'd do it again.
By the way, you aren't the only one who has to clean out the garage before any more cutting can be done
