I don't have access to a table saw at the moment, so I was wondering if anyone has used a circular saw to cut MDF for this purpose and how well it turned out.

Would a guide be necessary? I'm assuming a higher tooth blade would work the best, would a plywood(very high number) blade give a nice, clean cut?

 

Use a finishing blade. As for the cut? I table saw really is nothing more than a stationary skil saw. For straight cuts definitely clamp on a straight edge to use as a guide.

 

Do a google search for a 'sawboard'. I made two (one short, one long) for use with my circular saw to take the place of a table saw that I do not yet own nor have the room for. I use the 18-tooth (I think) blade my DeWalt came with and it's fine. That's more of a rip blade though. I'm sure something like a 40-tooth or something would give a finer cut but will cut slower through the material. MDF though is pretty tolerant of coarse blades due to it's make-up of being just sawdust and glue. It's other woods like plywood or hardwoods that you would want a finer blade for cleaner edges.

 

yeah circular saws work great... the pics ive posted of boxes i built i used a circular saw, personally used a 60 tooth finishing blade for nice clean edge and a piece of angled aluminum as a guide

 

I used a skil saw to cut the 4x4 sheets down to a size i could handle on my table saw. It worked fine and I just used a regular carbide tipped blade.

 

Go to the hardware store with a half sack of beer in hand (in a bag of course)for the guy to cut the sheets precise for you....

 

Rona I think it is will do up to 3 free cuts for you per sheet of wood or something like that. Just don't expect it to be too precise, even if they have a big table saw or just a panel saw (upright). I've had these services done from various Home Depot and Rona locations around the Lower Mainland and have had wildly varying results. It's not that they don't try, but moreso the equipment they are using is sketchy at best due to it's constant use and minimal maintenance.

 

I always try to get them(Rona etc..) to do the simple, big cuts that won't affect the box too much. The more precise or intricate cuts require a table of some sort.
