How to make a "Circular SAW TABLE" from a handheld Circular saw

This is my first Post, so please excuse me (as a Newbie) if I'm posting in the Wrong section.
Ive been wanting to cut Plyboard sheets I have for a few weeks now. I have a Jig Saw and a Circular Saw. However the Jig saw is slow in cutting long pieces of Wood and when I use the Circular saw, I always end up cutting the sheet crooked.
I recently saw on TV, a Table with a built in Circular Saw where u just position the wood and guide it slowly to produce a perfect straight Cut, However when I prices these, they are Very Expensive.
I was wondering if some one can give me a plan or instructions where I can make this table circular saw from with Hand held circular Saw (Inverted and attached).
I did a search but havent come up with anything similar to what I described.

Using a circular saw upside down placed in a jig is very dangerous. Please search on "panel saws" or "saw guides". These are attachments or jigs that you can build essentially turn your saw into saws with guides that will cut long straight cuts. You use the circular hand saw as it was designed to safely work. Good luck.
I have to agree with the above poster about the safety aspects of this. While it is possible I would not recommend it. What you should do is get a long 2x4 or anything else that will work as a straight edge. Clamp this to your workpiece so you can run your saw up the straight edge of this "fence". Doing this will produce a very even straight cut.

If you need to cut plywood, clamp a straightedge to the work with the proper offset so that your saw guide can ride along the straightedge and your blade will cut in the proper spot. Much less effort. The item you saw on TV was probably a glorified overpriced proper table saw. They're great things to have, but you can't really make a circular saw table like you can make a router table. Maybe bolt your circular saw via the steel plate (guide) around the blade to a table, right-side-up. At least my circular saw has one of those. i dunno about yours. The item that makes sure it's resting flat on the work is what you'd need to bolt through. Then you can have a stationary saw that you feed into without having to turn things upside down.
