Sorry, but I love making sleds. This is the first dado sled I have made. Comments and suggestions welcomed! This one is quite a bit smaller than the cross cut sled(s) I made. It’s 24” by 24” square. I was always a little hesitant to cut dadoes on the table saw, but I think this makes it a lot safer.
Base – 1/2” plywood 24” by 24”
Runners – Hard Maple
Rear fence – 3/4” plywood x 2 – 24” wide, 3 1/2” tall, 1 1/2” thick
Front Fence – 3/4” plywood – 16” wide, 3 1/2” tall
Incra T track
Woodpeckers T track stop
Kreg track clamp
Red Oak handle and stop block
I borrowed the t-track and t-track stop idea from my other sled. I didn’t get one with a ruler this time though. It is very handy. You can set your measurement with the track stop, then slide the stop block out of the way when making your cut. When you need to cut the next piece, slide the stop block right back. Much cheaper than a swing stop. I also routed some slots for the track clamps to hold the pieces down. There is a blade guard on the back.
I initially cut this with my regular blade. It made it easier to square the fence since I have a straight edge that is exactly as thick as the blade kerf. Once the fence was squared using the 5 cut method, I put the dado on in a 5/8 configuration and cut the slot. I made many test cuts and they are all square. I even cut a “tenon” to be sure all the sides lined up, and they did
The other “accessory” I made is a fence for rabbeting. It’s a 6” tall piece of 3/4” melamine shelf. I got the shelf because it is banded on the edge. That stuff falls apart if you move it around a lot. Securing to the fence on the R4512 was tricky. There are t-tracks in the fence, but the tracks are really low. The bolts would interfere with a pushstick/pushblock. I attached it to a piece of wood and used the t-tracks on top of the fence to secure it. I routed out a slot for the t-track style feather board to slide back and forth. I then raised the dado blade into the melamine so I can cut rabbets.
That Freud SD208 cuts pretty clean:
