Hi All

I am gaining a little experience but need help with a sled I made for cross cuts. I have been working with small pieces but now I am building a bookcase and the pieces are too long to use a stop for equal length cuts.

What is the best way to make sure my cuts are uniform?

Thx,
Dog

OK I think I see how – bring the end over to the fence then back off the fence and try to keep th piece in place.

If I understand what you’re asking, I would clamp a block to your fence and set your fence at your desired length plus the thickness of the block. Then set the piece to be cut up against the block and secure it in place and cut. You don’t want your piece riding along the fence the whole time cause it could get caught and bind and possibly kickback. Hope this helps.

For LENGTH, I totally agree with Matt: stop blocks.

If you’re wondering how to get it SQUARE, though … well … that’s the purpose of a well-designed, well-built, and properly squared crosscut sled, in the first place.

Step one IS ensuring that YOUR fence (the back fence) IS perpendicular to the blade.

Did you do that, already, on yours ?

I suspect that the boards you are working with are going to be too long for the fence based ideas suggested above.

Personally, I would rig up a way to get a stop block out to the end of the board with a temporary extension attached to your sled. Make an L-shaped piece of wood and screw the long piece to the sled in front of your stock.

In many applications it is not essential that the board be exactly X inches long to the 1/1000 of an inch but it is essential that all the boards be of exactly the same length. You need a good stop to do that.

You may even try to tape or clamp a stack of boards together and use a circular saw to cut them all at once. Clamp a carpenter’s square to the boards and run the saw along the square. If you are using dados to secure the shelves it would hide any tear out.

Thx guys – yeah the problem is boards longer than sled so it looks like screwing on a temp ext is best.

Great help – might not have thunk it up – better at golf, good thing (:>

Trim both pieces to a rough length using a circ saw…maybe an 8th heavy, or less. Put one on the table saw to clean it up (fence removed) to exact length, then clamp the two boards together and use a router to flush trim the second board.

Sounds crude but in the past I’ve stacked something heavy at the proper distance to the saw blade and used it as a stop. Just don’t bang the boards up against it and it shouldn’t move. I’ve used bricks on a cooler for example.
