Is this many saw marks normal? Or is there some adjusting needing done on my table saw? I just got the saw so I’m unsure.

What type of blade are you using and have you tried a different blade. It could be the blade. Also, it could be that fence is out of line with the blade.

Well, based upon the picture, I would say any saw marks you have are damned near invisible. I wouldn’t worry about it.

I tried posting a picture. Not sure what happened. I was wondering if I was a fence issue. I had a mother table saw and returned it. But when I cut with it, it’s didn’t leave any saw marks

Those marks should not be there. Either your blade is changing position ever so slightly, or your fence is moving, or you are not feeding it through straight and the edge against the fence is coming away a bit as you push it through. I never see that unless I mess up and allow the wood to come off the fence a little bit while pushing it through.

From your picture that looks like a very tall rip to me. If I were making that cut, I’d cut kerfs from both sides, and finish the cut with a hand saw (or bandsaw, if you’re lucky enough to have one), especially if your table saw is not a beast anymore. Then you’ll need to take a handplane to it to flatten and smooth out the saw marks. This is often necessary even if everything is adjusted and the stock is perfectly prepared for the cut. Also, it sort of looks like construction lumber a la 2×4 given the knots I can see. Are the other three sides square and flat? If you haven’t run the other sides through the jointer and planer, then it’s likely that your stock is not flat and square, which will result in saw marks (or worse). I also can’t tell what blade you’re using, but that may be part of the story.

Hope this all helps! Best of luck!

The quality of the cut is the result of several different factors that include the proper setup of the saw, an arbor that’s flat and spins true, a flat rigid throat insert, a quality blade that’s sharp and suitable for the task (stock blade’s typically don’t make the grade), proper tightening of the blade nut (not overtight), straight fence that’s parallel with the blade, good technique and ample motor power, a reasonably flat saw top, and flat straight stock. If any one of those components is off, it’ll translate to the cut. If that board wasn’t flattened and squared prior to ripping, you’re far more likely to have saw marks even if everything else about the setup is perfect. A board that rocks and moves during the cut won’t leave a perfect cut. If everything is dead on including a flat board, you could have some runout in the arbor or the saw blade.

Either way, the saw is capable of leaving glue ready edges for joining, but it’s never finish ready IMO.

Could be the blade, but you need to rule out the machine set up.

My first guess is your fence may not not parallel to blade.

Check all parameters before using further:

Blade 90 degrees to table
Blade parallel to slots
Fence parallel to blade

There are plenty of videos out there if you need them.

Don’t know what kind of machine this is, but if its an older Craftsman, the big issue is the fence. They were just poorly made.

Get that result 90% of the time in the UK! – purely because good quality equipment is very expensive, and much of the gear here in the UK, is imported from the Far East!

It is a brand new delta 36-725. I got the same issues when just cutting a 2×4 in half so I did this to exaggerate the issue. To see what’s going on. ill get out there later today and start messing with the alignment. I just wanted to be sure that this was normal or not first

Are you ripping a pine 4×4 and expect a mirror finish? Unless you had some kind of automatic feeder to regulate speed and the board had one side jointed already and everything was aligned perfectly and the Jupiter aligned with Mars I’d say it’s not gonna happen and you shouldn’t really care. If you want perfection leave a bit of waste then run the board through a plane or jointer.

That’s par for the course for construction lumber.

Was this 2×4 jointed? Kinda looks like it was wobbling as it was cut.
