Introduction: Making a Cross Cut Sled for the Band Saw

About: Hi I'm Linn and on my Youtube Channel I have lots of great videos about building, construction and fun projects. You can also check out my site @

A cross cut sled for band saw is a very useful addition to any shop and will make it a lot easier to get straight cuts on the band saw. This particular jig features a very useful clamping system which makes it easy to hold the wood in place, and make mitered cuts too.

So let's go over how to build this jig!

Step 1: Materials

This cross cut sled is designed for my Laguna 14-12 bandsaw, however you could utilize the same concepts and adapt them to whatever bandsaw you have. I wanted a jig with plenty of support on both sides of the blade. This jig also has a stop block underneath, so it stops right at the leading edge of the fence.

For this build I'm using half inch baltic birch plywood.

So first I'm going to need the main piece, this one measures 20 by 20 inches.

For the runner I'm using a piece of tropical camaru wood, but any hardwood would work.

Then I need a couple of additional pieces of plywood for the front fence, the back fence and the bottom sled


I'm also going to need some 1/8 inch, 3/4 inch angled aluminum, the clamp bar and knob, which I'll go over how to make as well as some screws.

Step 2: Fence

First of all, let's prepare the wood for the fences.

So I'm going to cut some of the plywood up so I can glue two pieces together, to get thicker pieces for a more stable fence. Then gluing and clamping.

I need a piece for the stop block, so cutting one of the glued up pieces on the table saw and the miter saw.

Then I'm going over the concept here by bandsaw. So I have my piece of camuru that slides in the track.

So bringing the main piece over to the bandsaw and seeing where I want it positioned. This is not critical, it's more for balance. So I want to makw sure it's straight, and I'm marking out where the blade is as well as where the track is underneath.

I want this jig to be very precise, so it can cut very straight lines lines which is why the runner needs to be very square with 90 degrees to the front edge.

Step 3: Fence Position

It's important that you figure out the right position for the fence. So here you can see when I'm cutting, the front fence lines up with the blade. And once I'm done with the cut, the jig is stopped by the stop block underneath. So the fence needs to be positioned at the same point as where the blade stops cutting.

So planning out the where the fences should go, and also seeing how far in they should be so they don't interfere with the blade guards when they are all the way down. If you'd put the fence all the way to the blade, then you'd have to have raise up the guards to the height of the fence which does not leave as good of a cut.

Step 4: Assembly

After making some marks, I brought it back in the shop. I find it useful to mark everything as clearly as possible, ideally on both sides of the piece. So bringing down the lines here of where the track needs to go, as well as where the blade will end up, and then carrying those lines to the underside.

But before attaching the track, I'm going to pre-drill holes for where the front fence is going. So predrilling on the top, where I have marked out the position, then turning it around and countersinking, cause you don't want any screws scraping the top of the bandsaw table.

Next I'm clamping down the back stop first, and then gluing the runner in place, clamping, and putting down some screws.

Then countersinking, gluing and securing the back stop down with some screws.

Now time to mark out where the back fence will go. And as you can see here, the position of the back fence is related to the length of clamp.

So I have marked out where it needs to go, and then just drawing the lines here so I can pre-drill and countersink from the back.

Then after marking & predrilling the fence pieces here, I'm attaching them to the board with some screws.

Step 5: The Clamping System

And now the basic concept of the jig is finished and I can take it out to the bandsaw and make that first cut. Now, let's work on the clamp feature. So for the rails I'm using angled aluminum. And as you an see on the cross cut sled here it's important that the rails are up a bit so you have that space in between the plywood and the metal. So drilling holes in the aluminum and making sure to drill on the bottom side to account for that. So I start with presinking the holes with a large bit. Then I drill all the way through with a smaller bit.

Now I have removed the fences from the board, and I'm attaching the metal to the plywood, making sure to raise it up a bit from the edge to provide that lip. And you need plenty of room so you can move the bar freely. Then I cut the aluminum on the bandsaw, and I'm just using a regular 1/4 inch blade for this.

Then once they're cut to size, I screwed the aluminum back on the fences. So to make the knob, I'm using one of the glued up pieces of plywood here. I made a circle using a compass, and then I'm using angle bisecting to create an octagon for a nice knob. Then I mark out the head of a 5/16 inch bolt, drill a 5/16 inch hole. And then I chisel out the head for the bolt to sink it in. Making sure it fits and then I cut the octagon to size on the bandsaw.

Now I need a smaller knob for the bottom of the bolt, so I have another piece of glued plywood here, then marking and chiseling out a space for a 5/16 inch nut.

Next I'm drilling and chiseling a hole in a piece of plywood for the bar for another 5/16 inch nut, and here you can see the pieces for the clamp feature.

Then I'm epoxying in the bolt in the knob, the nut in the holder, and the nut in the bar.Then I have two small pieces of aluminum measuring the width of the plywood bar, and I'm securing those on the ends, again making sure to leave some extra room in between the plywood and the metal.

Step 6: Finishing

So now the bar can slide in in between the two fences here. And it's easy to secure something in position. This also makes it a lot easier to make angled cuts since you can draw your angle and then secure it in place with the clamp to follow that line.

To protect the jig, I'm putting on some shellac. And to protect the bandsaw and making the jig slide better, I'm putting down some mineral oil wax polish. Also giving the bottom of the jig a nice coat.

So the cross cut sled is finished, I can move it in, it's nice and balanced on both sides, and I can secure any material with the clamp. I can also make angled mitered cuts really easily using this. And then of course you can also just hold the wood to the fence without the clamp to gain support for a nice straight cut.
