Hello All,

Let’s say i have a piece of plywood 40×40, and want to rip one side so that the new dimensions are 40×38. On my small contractor saw, would it be safe to cut the 2 inches on the side between the blade and the fence? There isn’t enough table width to accommodate a piece that large to rip the 2 inches on the other side of the blade. Thanks for your replies.

That shouldn’t be a problem as long as you have control of the 2” piece as well when you cut it. (like have 2 grrippers to push it along to have total control). Also make sure to take into account the blade kerf because you want to keep the larger piece rather than the cut off.

+1 ^^ above.
The dangerous part will be when you’re stretched out over the saw to cut the last 6 inches. Recommend mocking up an outfeed table at the same or about 1/2 inch lower to support the large piece of plywood you’re keeping as you extend yourself over the table. I’ve often used heavy things around the shop to help with outfeed.

I would clamp a guide on and use a circular saw.

By yourself? I wouldn’t do it with a small saw, unless you’ve built a table around it. Better to use a circular saw. If you have someone that can help you with the off cut, then as long as both of you know how to do it, then you will be fine. The operative phrase part being that you both have to know how to handle the cut.

Although I have a table built around it, I think that piece of plywood is just too big for one person to handle. I’ll go the circular saw route. Thanks for the replies.

I’ve cut 4×8 sheets on my saw. The good thing is a 4×8 sheet is heavy and possible kickback is minimized.

Ideally it’s good to have a little more than half of the board supported during and after it’s been cut. You might benefit from going through the motions with the saw off and blade down to see if you’re going to have major problems.

I agree a circular saw might be the way to go.

Yeah, I did the cuts with a circular saw. No need to risk injury when an alternative way to cut is available.

I cut 4×8 sheets on an 8” tilt table saw back in the 50’s when I was young, dumb and stronger than now. Today I still cut 4×8 sheets on my 10” cabinet saw, but I now make sure there is adequate support for the offcut. Nothing like experience .
