Question about Bosch 4100 09 10" Worksite Table Saw W/Gravity Rise Stand

1 Answer

Riving Knife won't go down enough.

I want to install a dado set, but when I lower the riving knife to as low as it will go, it's still above the table level by 3/4".

    Never mind. I'm new at this. I figured out the "problem". There isn't one with the saw, it's with the operator. Thanks anyway.

I have table saw (r4510)it has a spliter mounted on the side next to the saw blade hold question how do I get the spliter out of the holed out?

I assume you are talking about the riving knife behind the blade.
when you take the hole cover off the saw table, you'll see a lever down on the side of the riving knife that can be either straight up or you can pivot it down toward the blade. When its up, its for through cuts, the riving knife sticks up higher than the blade. <b>When you turn the lever down toward the blade, the riving knife drops down a bit so you can make kerfs that don't go all the way through the wood.</b>
When you take the blade out, you can also take the riving knife out if you are going to put a dado cutter in, but <b>don't remove the riving knife</b> otherwise.

Wood has all kinds of internal stresses that are relieved when you cut the wood. Often the slot the blade cuts results in the two sides of the wood curving together and pinching the blade. This if very dangerous because the back of the blade can get pinched and through your wood at you faster than a major league pitcher can throw a fast ball. I still have a bruise on my chest from this happening to me before thanksgiving. Good thing it was the whole end of a 2x4 and the wood didn't split into a sharp spear as the blade grabbed it. Don't take out the riving knife unless you are using a dado blade and then put it back in right afterwards.

If you don't have one, here's the manual for your saw:

Centering saw blade

The most important thing is that the blade and riving knife are centered with each other. If not, you may have to shim the riving knife.

The bolts that hold the carriage under the table are intentionally sloppy so that you can loosen them and align the blade/knife with the miter gauge slots.
Lay a long metal straight edge against the side of a carbide blade teeth with the blade all the way up, and make sure the straight edge is parallel with the miter gauge slots in the table. Then tighten the bolts on the underside.

I'll suggest you look at the removable Excalibur Riving Knife from Merlin, which I've used(loved) or the Shark guard, which I haven't.

Powermatic 3000 saw not cutting true , have blade true w/top & top true w/fence & even removed splitter to no avail???????????

The blade and fence must be parallel to the miter slot. Splitter or riving knife needs to be parallel to the blade.
