Instructables
In an attempt to save money (and not clutter up my work space with more tools which I don't have anywhere to store) I created a mitre box for my circular saw.

You may have seen a few other instructables about turning a circular saw into a table saw, and I have a similar project in the works once I finish my work bench but first I needed a mitre box so I borrowed the idea and turned it up side down.

Materials:
MDF or ply wood (left over from other projects)
Structural pine (left over from my work bench [instructable hopefully coming soon!])
Other pine (again, left overs)
Screws (who doesn't have a bunch of these laying around?)

Step 1: First stop block

Put your circular saw on the MDF, lining up the front end of the foot plate with a straight edge (this is the edge we will be working off for the whole project to keep things square). Draw a line from the front mounting hole in the foot plate parallel to your working edge. This is going to be the pivot point for your saw to make angles cuts on your mitre box.

Make a mark a few centimetres away from your working edge past the pivot line. This is where the front edge of your stop block is going to be.

The stop block is how you will quickly and accurately line up the saw each time you want to make a perpendicular (90 degree) cut.

Take a piece of scrap pine with a straight edge. Use your quick square (or any square if you don't have a quick square {I'm not sure how you could live without a quick square!]) to line up your scrap pine block perpendicular to the working edge. Line the end of the block up with your mark and screw it in place.

well done. I like this...but like you said ..it's a bit slower than a compound saw...the solution would be for you to build your table saw and then make a sled . that too would give faster and accurate straight and with stop blocks miter cuts...good luck in the competition..

I do have plans for a table saw, with a sled and so on, however I don't have a workbench yet, Once I have that made up I will be making up a table saw for it.

That being said, it is useful to have a portable system. With the mitre box I can easily take to wherever I need it, even to other peoples houses if I am helping with someone else's project.
how true! btw...seems like you and me are the same in one aspect...waiting to build that table and so on...but you are one up! you have a circular saw! I'm waiting for someone to bring me my circular saw from UK! :-D

My work bench is coming along.... very slowly. It's really only a few days worth of work, but I've been working on it for about 2 months now, and there is still a day and a half more work to do.

It just seems that the world is conspiring against me ever finishing it. I never get more than an hour or 2 to work on it when I have time off work, and that's only enough time to get set up and pack up again.

Still I have a couple of days off coming up, who knows I might finally get some time to work on it!
