![]() ![]() Contact between saw teeth during operation can severely damage them, and could cause them to chip or break off. Make sure the blades are installed so the teeth do not align with those on either side. Small pieces of debris trapped between blade segments will alter the size of the groove the stack cuts. ![]() Before installing the stack, check for sawdust or other contamination on the mating surfaces. First Things Firstįor any dado set to cut correctly it must be installed and maintained properly. After installing your dado stack, and before plugging the saw in, make sure there is sufficient clearance within the guard. The blade guard on most radial arm saws will work with a stacked dado set but make sure to check your instruction manual to confirm that and for limitations. This style guard can remain in place during dado operations. If you do a lot of dado work, (or even if you don't) you might want to consider one of the overhead blade guards available. I like using push blocks, normally used with jointers, as the grip of the rubber sole offers firm control of the wood and the handle separates my hands from the blade should something go wrong. Even though dado blades are not intended to break through the upper surface of the wood, it is a good idea to use some form of push device to add distance between your hands and the blade. Since the blade guards that come with many table saws must be removed for cutting dados, extreme caution must be used. Dado Blades and SafetyĮven though dado blades (on a table saw) do most of their work while covered by the wood, eye protection remains very important. Whether the wood is the original factory thickness, or has been machined in our shops, matching our dado stacks to the actual thickness is the key. Those who purchase "3/4-inch-thick" plywood, and cut a ¾-inch-wide dado for it are in for a rude surprise when the plywood fits about as good as a VW in a Buick garage. Knowing the actual thickness of the wood we want to create a dado for is crucial to finding the proper setup quickly. Variation in wood thickness is a problem we all have to deal with. That suggests problems with dado fit are more likely the result of improper technique by the users, variance in wood thickness, misalignments of the saw, or some simple miss understandings of how to use these sets best. ![]() Note: This story is being updated and there may be some short (hopefully) periods when photos don't show up as we change them out.ĭespite the large number of emails I have received on problems getting stacked dado sets to create good fitting joints, no specific brand or style of stacked dado set emerged as a primary culprit.
