Ripping plywood to 5" strips, move the fence or not?

I have 3/4" plywood that i have broke down into 2'X4' panels. I plane to cut each panel into 4' X 5" strips. I will later cut these in half at 45 deg. for french cleats. I watched a video where I observed the operator cut 5" off all panels and stack them. Then move the fence 5" closer to the blade and repeat.Doing it this way leaves the larger part of the board between the blade and the fence. It looks to me that I could just set my fence 5" away from the blade and run each panel through without the repeated fence adjustments and end up with all strips exactly the same 5" width except for the last piece left at the end. Is there anything wrong with my doing it this way? That little voice in my head keeps asking is this safe?

Thanks for the replies. My fence is crappy and requires that I use a square to align it after each move. To make matters worse it had two locks to clamp it to the table. This is the reason I would rather not move it. I have push sticks but prefer using the micro jig because it allows a bit more control to add some pressure keeping the material on the fence.

1. Is your saw table large enough to support the plywood during the cut?

- By "large enough" I mean that the piece outside the blade does not fall off the table at any time during the cut.

- If so, a fence set to 5" is safest in this case. Notice I didn't say "safe" - you still need to be very aware of what is happening during the cut.

- If not, it depends on how much of the waste side is unsupported. A little hand pressure to keep everything stable is much better than trying to stop the waste side balanced in space.

- If you can set up an outfeed/sidefeed support (even if temporary), you can offset some risk.

2. Do you have a riving knife?

- If so, that makes the situation much safer.

3. Do you have push sticks?

- If so, use them - long ones. By that I mean longer than 6".

- If not, get/make some. A strip of scrap with a notch in it works just fine.

If you don't feel totally comfortable with the risks change your setup and process until you do feel comfortable. A lot of this choice depends on your own skill/experience level. Don't let anyone ever tell you to do something that you don't feel safe with - especially around a table saw.

Had a day in the shop. Even though my saw isn't large my two foot wide by four foot long ply wood was supported. Had a slide out support augmented by a support roller. Riving knife in place and all went well. I set the fence at 5" and did repeated rips. Never felt unsafe however if the pieces were larger than two feet all bets are off. I now have two walls of the receiving end of french cleats. I love how woodworking unleashes your mind, I look at this wall and think "I can do anything with this blank slate."
