Was learning me some #woodworking theory on YouTube, and the guy on my favorite channel recommends to just get dado blades and do rabbet joints for pretty much everything.
Turns out dado blades are illegal in the EU, because we're all little children who can't be trusted to use big boy tools: https://www.bosch-professional.com/gb/en/community/category/dado-blades/389289-t
@raucao you can usually also use two cuts with a circular saw to make a rabbet, or a router to make rabbets and dados. So I've never missed dado blades.
@daniel_bohrer I know, but using a router seems like considerably more effort than a table saw.
@raucao Dado blades have a significant IMHO disadvantage for a hobbyist. They provide a set of discreet dimensions. This means you have to prepare (plane) the piece you would put into the dado exactly to that thickness. For one off jobs it is more convenient to transfer (not measure) the thickness of the stock (e.g. shelf) and create a groove of matching width with two cuts and a router (or a router plane).
@steelman But you can set the height of the blades and carefully approach the width with multiple cuts, same as without dados. No? Seems like the fastest way to make wide rabbets.
@steelman But you don't need two cuts if you just approach the width with multiple cuts. The way I see/understand it, is that dados just make that both much faster, as well as cleaner, than when doing the same with a normal blade on a table saw.
@steelman (By the way, I went with a router now.)
@raucao The two cuts I am talking about are the first two of multiple, the ones that define sides of a groove. (See the video above.)
Re: faster. Yes, but you need the other piece of the joint to be exactly of the thickness of the dado, which may require additional work. If, however, you use kerfmaker and multiple passes (or whatever other method to remove waste) you always get a dado that exactly matches your material.
Re: cleaner. Yes, if you don't use a "flat bottom" saw blade.
