    New miter slot and adjustable miter sled pics

    This last weekend I finished-up my new extended miter slot extension and my miter sled.

    My old miter slot extension was the same depth of the main table (about 22.25"). I realized after making it that it coulda been longer. So I made a new one that is 30" long. This allows me to be a little more precise and also handle cutting even wider pieces.

    When the table saw's fence is pushed flush against the addon table, the fence's T-bar needs a little space under the miter extension. I didn't show this in the pictures, but I had to make a little notch to accomodate the fence.

    This miter slot extension prevents you from moving the fence to the left of the blade. I never do that (and I kept my old extension table, too), so not a problem for me.

    I used an Incra miter slot (with the T). I found these to be far superior to the Rocker ones. I'm amazed at how accurate these are.

    With the miter slot extension finished, I decided I really wanted a miter sled. Some of my next projects are going to require compound angles, and I didn't want to try doing that with larger pieces and the standard miter gauge.

    This miter sled was made for about $25 (not including the Incra runner which I already had), and allows me to make dead-on 90-degree cuts. But it also allows me to adjust it a little and make dead-on 45's. Or any angle I like. It only take a minute to adjust it, and I can make pencil marks for commonly used angles.

    So when I was all done, I was finding every piece of wood with a ragged end and trying it out. I knew I was in heaven when I was was struggling with three different triangles and three squares to check the cuts. The more I checked for accuracy, the more I found.

      Very nice piece of work. It looks like it will see a lot of work.

        Looks great. Are there any kind of alignment stops for easy set up of angles?

          Not yet, all I've got marked (w/ pencil) so far is 90 and 45-degrees. I can either use a protractor or do a little math to set it.

          From the left edge of one t-slot to the left edge of the other is exactly 12.5". So, if I want 22.5-degrees (for example), I keep the right-hand bracket intersecting the 90-degree mark on the bottom edge of the board and move the left-hand up 5.178" from the 90-degree mark. If I convert/round that to 5-11/64", my angle will be 22.47-degrees.

          I've thought of getting one of those digital protractors Loring has for setup. Or maybe I'll glue one of those rules (provided I can find one graduated in 64ths) to the side of the t-slot. Maybe both.

              The plans just kinda evolved. I had seen a sled made from Shop Notes plans that used aluminum angle as the fence, and it wasn't adjustable (90-degrees only). Looked pretty good.

              Then I saw the Dubby sled featured on this page:

              This TheWoodshop.20m.com web page shows how to make your own crosscut sled.


              And thought it was neat, but I didn't have an circle jig for my router and wanted something where I could actually reverse the fence to the other side of the sled.

              So I used Google to search for table saw sled photos, and found this:



              And then used that photo and my current sled for inspiration.

                  Should answer your question:

                  This is the place to ask questions about the Ryobi BT3 series table saws. Please limit the posts to this topic only.

                    That looks like a really great setup.
                    Nice job!

                        OK - I know this is an old thread but really like this shop made miter slot table.

                        How far did you place the slot from the blade. I found the Unisaw left miter slot is about 5-1/2" from the blade flange.

                        Guess it's not a big deal - just wondering what you used and why.

                        Thanks,

                        Mike
