Question Table Saw Help - Wood Won't Pass Through

Hi everyone, I am new to woodworking, and hope you can help with a question I have. I recently bought a table saw, and have been using it to make cuts with plywood and have had no problem.

However, today, I tried to cut through a piece of particleboard shelving (the one's you can buy at Home Depot) as I need to reduce the width of it. When I attempted to pass it through, my table saw seems to "stop" the wood, and not allow me to pass it through. It will only cut up through the length of the blade (10 inches). I did not force it through for fear I might be doing something wrong.

Any ideas? Thank you for any insight you may have.

Is the riving knife or splitter still attached to the table saw?

sometimes the veneer hangs down and catches on the throat opening. make sure the throat plate is level with the table top.


if the blade is down, does the board stop?

Welcome to the forum, Mir! When the board stops turn the saw off, unplug it, then go to the outfeed side and see if you can gently lift it to see what it is catching on. Like Tim and Chuck said something is catching and it could well be the throat plate. Probably won't be that hard to find but just be careful.

Move the far end of your fence about 1/4" to the right.
It sounds like your wood is binding against the fence.

If you don't have time to do it right the first time, when will you have time to do it over?

Move the far end of your fence about 1/4" to the right. And try it again.

Also check if the riving knife (if your TS has it), is in the correct position for through cut.

Thanks everyone! I will certainly check all of your recommendations tonight. I do have a riving knife and will look into this, along with the throat plate and fence.

Speaking of riving knife, check the thickness of it. If you're using a thin-kerf blade with a riving knife meant for a full kerf, you're gonna have a bad time

If it worked for plywood, it should work for particle board, and the riving knife would not cause the "stopped" condition. Sometimes there's a "hanging chad" that stops the forward progress on the edge of the saw table. It can be a splinter, a knot or other protrusion that is hanging below the surface.

It can a also be a binding condition from a fence that has become whacked toward the blade for some reason. Check the fence to see that it's parallel to the miter slot when lock down in random locations. Check to see that the riving knife is in the same plane as the blade by running a straight edge along the blade and past the riving knife. If it stops at the knife something is "out of order".

This is not rocket surgery and should be easy to figure out.

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

Do you have a blade guard on? I ran into a problem when ripping about just under 1" off a piece of wood. My guard would ride just on the edge of the wood. From time to time it would slip off and get wedged on the edge. I ended up locking the one side up to get through the cut.

Found the issue

Hi everyone,

Thank you so much for all of your help. I looked into everything you had recommended (blade guard, riving knife position, throat plate), and it turned out that it was the throat plate. It was not level with the surface, and after running the wood past the blade, it was getting stuck at one of the grooves of the throat plate.

This was a great learning experience, and can't thank you all for your guidance. Looking forward to learning more here.

Glad you were able to figure out your problem. Also glad to see you're using the guard...keep it up!
