Default Crosscut sled?

Why we call it crosscut sled? canít you rip a piece if it fits inside the sled?

Thank you

I'm gonna guess it was because the original intent of the inventor was to make it easier and safer to cross cut boards and panels before the advent of the "chop" saw, or the radial arm saw. But I've been wrong once or twice before!

Because, the norm, you cut across the grain. You rip cut with the grain. This is why you have crosscut and rip blades.

Thank you Ken

I know about across the grain / with the grain etc. But can you put a piece inside the sled and cut with the grain? Is there any safety issue?

Hi Nicholas,

To answer your first question, yes. Second question, yes.

The difference is, the cut. You get a better cut with a rip blade if you're ripping. Same with a cross cut blade for cross cutting. If you intend on doing both, best to get yourself a combo blade. I have a freud thin kerf combo and this blade just rocks!!

Yes! There is a safety issue making a rip cut with a cross cut sled.
It's called a cross cut sled because that is what it is intended for. Not rip cuts. Other wise it would be called a rip cut sled.
Rip cuts should only be made using the fence of your saw, that is, unless you enjoy having the wood thrown back in your face. Also, the fence should never be used when making cross cuts for the very same reason. Safety!
Can you say kick-back?

There are sleds for ripping. Generally they are used to make tapers, such as table legs. They are usually called taper jigs.

Thanks George, I do stand corrected. I've seen many sleds have clamps that helped hold the piece in place.

That is correct, Mike. They are not cross cut sleds, but a specialty sled made for that one purpose (taper jig) just as the cross cut sled is for a specific purpose (cross cut).

Ken, I agree there are some cross cut sleds with hold downs that could be used for holding a piece to rip cut. But, look at it this way; most rip cuts are for making a board a specific, measured width that you want to be exactly parallel to the opposite edge. Without using the fence to insure the equal width of cut, IMHO, you are just pis...., er, wasting your time.

I use a sled to rip cut one edge(usually the bark edge) off a piece of lumber with nothing touching the fence. In essence if you do this you just jointed one edge of the piece of wood.

Then I place that cut edge against the saws fence and cut. The two sides become perfectly parallel. I can use this same sled as a tapering jig also as I can move the angle of the sled's fence.

The difference between the cross cut sled and a sled for ripping is the orientation of the sleds fence system. A cross cut sled can only hold a piece so long and unless the fence is able to move parallel to the cut it gets unsafe as the piece gets longer.

A Cross Cut sled has a fence perpendicular to the blade.

A rip sled has a fence parallel to the blade.

A Tapering jig has a fence on an angle(but closer to parallel with the blade than perpendicular to the blade).

A Miter sled has a fence on an angle(but closer to perpendicular with the blade).

I have one of each of these plus a sled for only 45 degrees.
