For those of you that have done small projects in the past and wanted to incorporate dados, but hate going through the annoyance of doing multiple test cuts and adjustments of the dado stack, then you you will love this easy to follow tip! Lets begin……
1. Using a miter gauge and a stop block, set up the stock in the position you desire and add the thickness of your adjacent piece you are making this dado for. Then put your adjacent piece of stock between the stop block and the workpiece you are making the dado in.
2. Now run the stock through your blade (note: I am using one of the outer blades of my dado stack to make these cuts, it measures 3/16” wide)
3. Now remove the adjacent stock
4. Slide your workpiece over, which will be the EXACT thickness of the adjacent piece you used as a gauge. However, if you were to run the stock through as is, you will over cut the thickness b/c you are still on the same side of the blade for your measuring. So that is why you need to use the 3/16” brass bar feeler gauge to push the stock to the other side of the blade.
5. This will leave a section of wood between the kerfs. Repeat this process for all dados you want to make. Do not continue to next step until you perform this step for each dado.
6. Add two chipper blades and one outer blade in addition to the one you are already using in the table saw. This will remove the remainder of wood without disturbing the original kerfs. (Note: Do NOT change the blade height)
7. Now your test fit will be perfect if you performed this correctly and used the correct spacer for your blade.
I hope that this has helped you understand how to get perfect dados for any piece of wood you want to use in your project. I recommend this for all small projects but if you have more than 5 or so dados to make (such as cabinet builds) I would take the extra time to set up your dado stack to make perfect dados on a bigger scale without having to make multiple passes that this method would require.
Thank you for taking the time to stop by and I hope that this has helped you out. Be safe out there and be safe in your shops and as always… BOOM!!!
