How To Install A Stacked Dado Blade On A Table Saw

December 21, 2018Olen Murriel

What stacked dado blade sets are is basically a series of specifically designed saw blades that are meant to be fixed onto your radial arm saw or the table saw’s arbor which is used to make partial depth cuts of different widths for rabbets and dadoes. The set of blades has two matching, full saw blades accompanied by a series of unique blades or chippers that easily fit in between the blades found on the outside. Think of these two outer blades as you would the bread on sandwiches, with your chippers acting as your ham or peanut butter and jelly.

(whatever goodies you love on your sandwich, really) in between the sandwich.

Installing stacked dado blade sets onto your table saw’s arbor will first require you to disconnect your saw from the power switch and then raise the saw blade as high as you possibly can The next thing will then be to remove the throat plate that’s used to cover the throat or wide opening in the saw table. After youVe done this you’ll then need to use the wrenches of the saw to remove the washer and arbor nut. Uninstall your existing saw blade and then place in a separate safe location or blade drawer if you have one. Just ensure you’ve set it aside in a place where the blade’s carbides won’t get damaged.

Most of these type of blade sets are usually accompanied by a carrying case which is meant to hold the chippers and outer blades together when not in use and in storage. When the two outer blades are taken out of the case you’ll notice that each blade is likely to contain a direction indicator located on one of the blade’s sides. If you hold the two outer blades vertically you should be able to spot the arrow pointing in a similar direction as the teeth’s cutting edge. If you see this then that’s confirmation that you’ve oriented the outer blades properly.

If to remove the saw arbor requires that you move the blade to the arbors right, first you’ll need to slide the saw blade on the furthest left onto the arbor. Placing the opposite outer blade should be done last. The arrow-side of the outer blade that faces the arbor nut and washer should be installed at the very end.

Afterward, locate the chippers. The set you’ll have will probably consist of four full-sized chippers. This means chippers that are 1/8-inch in width. They’ll be accompanied by one half-sized chipper which is one that’s 1/16-inch wide. The dado’s width is normally determined by how many chippers you end up installing. If you intend on making cuts wider than a 1/4-inch, place one or two chippers onto your arbor (do this in a way that the teeth of each chippers cutting face are facing towards the saw’s front when installed onto your arbor).

For further explanation on how many outer blades and chippers you’ll need to install for the various cut widths you require, you can take a look at this piece on stacked dado blades.

Once the requisite amount of chippers have been installed, onto the arbor place the second outer blade (with the blade’s arrow-side facing downwards away from your chippers), closely followed by the arbor nut and washer. Use the wrenches to tighten up the arbor nut, then lower the saw’s blade trunnion and then finally for safety, into the throat place a zero-clearance insert and you’re done.

If you need your stacked dado set installed on top of a radial-arm saw, it has a similar approach. However, instead of expelling the throat plate, in this case, you will probably first need to remove the blade-guard of the saw and then make use of a specialty guard that has the ability to accommodate your dado blade set’s width. A word of caution though. Never use a stacked dado set on a circular saw. It’s usually terribly frowned upon. A stacked dado set is simply too dangerous to be employed on a hand-held saw. Avoid giving in to the temptation of wanting to use a stacked dado set on a simple hand-held saw.
