Money tight, then buy a better blade,(alot cheapr than a tablesaw) a tablesaw would do the trick, but if you had a nice blade(carbide tipped--at least 30 teeth), it would make a big difference.

I used a 10+ year old circ saw with the proper blade of course and a piece of aluminum channel as my guide, I dont think you could get a straighter cut.

Try practice and go slower or maybe a friend and I haven’t seen many perfectly square T-squares. I don't know a better blade will help if he is that bad. Because it would cut faster and easier so any side-to-side movement at all would be increased. All else fails cut it a little long like 1/16 and use a good wood file. Last time I bought a good carbide tip blade I think it was $60 a little pricy.

You can buy decent blades for 15 bucks or so. And if you come down to using a wood file, make **** sure your file is perpindicular to your wood, or your gonna end up in worse shape then you started.

I can't follow a line worth ****, but I use a 2x4 clamped on both ends as my guide.

circular saw with a straight piece of wood tacked in to run against, can't go wrong!

I found a saw pimp at my local HD. He used to work at a mill. Nice guy and all my cuts were within 1/16th of an inch.

i use my step dads table saw and sometimes a cicular saw with a guide board clamped down. i am terrible at cutting out circles with a jigsaw though.

get a template of a circle. once you do that you have to cut 5 1/2 sidewalls for the box. then you have to have a bottom plate that has to be 3/4" thick. if you know anything about cutting wood then you are alright. but if anymore i'll be doin the work for you.

I used a table saw...but I also used a circular saw for a couple of my cuts. My dad has this tool that has string covered in chalk that you pull and it hits the wood and makes a line, and I Just follow that.

Hahaha, wow. Best post ever. Makes no sense at all. =)
That last pic sums it up nicely. I use a piece of scrap MDF with a factory cut egde. Works great for a straight line, but I have nothing to make sure itīs a right angle. It makes for some slightly slanty boxes. =p

i used to mess around with a circular saw, then a jigsaw...
finally i decided that the table saw was the answer...

for around 150 i got one at home depot that works like a charm...

cant go wrong with the table saw if you like building boxes...

So, does that mean that you dont use a carpenter's square? cause I believe that'll help you quite a ****ed bit. Square, 4' metal measure/guide, circular saw, two C clamps. Cheap, easy, great place for you to start.

MEASURE TWICE, CUT ONCE.

Now, I have a question: The laser guide is mounted to the saw chassis, right? :p:

right but it will assist you in following a straight line. if you can make a straight line then following it it easier. the laser is only an aid.

you know what works good if you do not have access to a table saw? if I don't have a straight edge handy, I just knock off about two inches off my sheet of MDF with my circular saw and have and instant straight edge. a brand new sheet of MDF comes perfect square, so you know the end is good for a straight edge. (just dont use the side you just got dont cutting). Also befor you make the cut measure out 3 inches on each side, that way you can take the new straight edge you just made to connect the dots and draw that straight line. Then measure out the distance from the inside of yor blade to the edge the saw rides along the fence on. Take that measurement, and from the line you just made to cut, measure back the distance you need to clamp your MDF straight edge and make a second line. clamp your MDF straight edge on that line and use it as your fence. Run the saw along that fence and you have the exact sheet of MDF just as square only 3 inches shorter. But now you have a straight edge, and a fence, and a technique when you dont have a long straight edge square, or a fence. This works good for a circular saw. Don't use a jig saw for cuts unless you have to. they are best for curves. They do okay for straight cuts, but not as good as a circular saw, or nealy as good as a table saw.

*Also, if you dont have any clamps, you can use an inch long screw to temp hold your fence down. That works well too.*

LOL the one I just posted is similar to alot of other peoples. THe same actually just worded different. I was worried mine wouldnt make sence. I have no clue what the hell you were trying to say, unless you really were just joking. I thought it was a joke, I laughed my *** off.

You do know that a circ saw can shift it's path...? Also, are you using any kind of square?

All you need is a long piece of wood/metal, two clamps and a right angle. Clamp the guide to the wood, make adjustments using the right angle and by measuing then tighten and cut.

**crap just saw that joe dirt already suggested this**

Tables saw and using a T-square or something that allows you to make the line you need to cut with a pencil, is what i do.

A GOOD pair of carbonized edged scissors (or diamond edged if you want to get spendy) will cut with ease through 3/4 MDF, not hard at all to follow a line with them either. My pair has lasted for 4 boxes and is still very sharp.

apparently it is, considering that you still cant cut straight.
