Topic tags/keywords: rip cut jig tablesaw

Hello,
I would like some advice on rip cutting a 2×4 (4 ft. long) into two 1×4’s using a table saw. I have a home-built sled with clamps to hold down the lumber and keep my hands far away from the blade.

My question is—if I cut half way through and then flip the board and do the other half, is this kind of a cut (only half way through) likely to cause kickback?

Thanks for the advice.
Dave

If you flip and get the same side on the fence, go slow (very at the end) , when it cuts thru, hold it on the fence and turn the saw off. small mark left by the blade. keep smiling John

I think others will chime in with the same thoughts.

Make your first rip a little less than half of the thickness. Then flip end for end and do it again.

Complete your cut with a hand saw.

Hope this helps.

You understand that after a couple of days, the 1×4s are likely to resemble pretzels, right?

If you start with KD 2×4s, it won’t be as bad, but the inexpensive ones warp pretty fast when you make a cut like that.

I would go buy a 1X 4 they are cheap and safer than ripping a 2×4 on the table saw. You will also have less of a chance of them warping.

I just finished resawing 33 5/4” x 6” x 8’ cedar deck boards on the TS by just standing them up and running them through. no sled or other stuff to get in the way. the blade is buried I don’t see where the concern is, just watch your hand placement as the blade exits the wood. I needed 500+ 3/8” x 5” x 12” pieces to make diamonds, scallops, points, and dog ear siding pieces for a historic house I am working on. after resawing I had 7/16 left then I planed them down to the final thickness. what you are trying to do will work but you will not have 3/4 when you are done 1 1/2 – saw blade = 11/16 left. also the odds the board is straight enough that the saw blade meets in the middle is rare. so if you were making 5/8 stock you would be good.

2x lumber is the wettest thing the borg sells except for those sodas in the case next to the checkout stand.
So +1 to everyone who said “you can cut them but they will turn into pretzels.”

Wait …........

2x box store lumber(studs) are actually 1 1/2 in wide correct?
1x is 3/4 in right?

Standard TS saw kerf is 1/8 in ??

Those 1x ’s are going to be missing 1/16 in in thickness because of the saw kerf even if you CAN resaw them right down the middle on a table saw.

Right??

IMHO “resawing on the tablesaw” is not the concern for kickback, but resawing crappy boxstore studs is the risk(of kickback/warping/twisting).

Right?

If you have a riving knife (or can rig up a tall splitter) you’ll probably be fine. I’ve resawn a LOT of boards up to 6” wide on my table saw without having a single kickback scare, sawing halfway through and flipping them end-for-end. At first I was terrified, but once I got used to seeing the blade that high – and made sure I was using the right type of push stick/shoe and featherboards – I don’t really have any problems with it.

But as everyone else said, in this case just buy the 1×4s. For a few bucks extra you avoid the hassle and won’t end up with warped results.

Since the question was asked, and 8 replies made in 2013, I would bet that he has cut them by now. :-)

That would be a good bet… particularly since they haven’t been back since asking!
