Topic tags/keywords: miter fold drawers cabinets rockler tradition tablesaw blade

I’ve been considering this new Miter Fold Dado set from Rockler: http://www.rockler.com/rockler-miter-fold-dado-set?sid=v9100&gclid=EAIaIQobChMIlrvSx8y31QIVS5V-Ch03kAOTEAAYAiAAEgIaYvD_BwE

How do you think cabinet drawers (kitchen) would compare in strength to traditional drawer construction methods?

(I did see the video of Andrew standing on one, but that was in the abstract, without a side-by-side comparison.)

With all the glue surface available, that joint should be very strong.

Lots of surface area, but it still is primarily end grain. A proper bottom panel glued into a rabbet along the front and sides (with consideration for expansion) would more or less make any weakness a non-issue.

The price for the blade set is high and you can do the same thing with a standard blade, but setup is tricky and this blade set look like it would make it very easy (a bonus if you plan on a lot of drawers!)

Depending on your definition/method of “traditional” drawer construction, I am guessing it will be on par with a standard rabbet constructed drawer as the glue area is similar. I would think it would be slightly “weaker” vs dovetail construction.

The real advantage to the miter fold dado is just that it is quicker and gives a nicer finished edge profile with a single cut. However when you get down to it, for a kitchen cabinet you will most likely be adding a drawer face to each box, so you will never see a corner connection that is a little bit cleaner than more traditional construction.

My 2 cents, or in this cast $350.

Is it really saving enough time to justify the cost? In a production cabinet shop making hundreds of boxes, it might be a cost saver. If I am a hobbyist or just working on my own cabinets and only making enough boxes for a single kitchen remodel, who cares if I save an hour on box construction?

The guy who invented it did a YouTube video of a strength test. He stood on it, etc. Eventually kicked it apart. It seems strong enough for even a heavily loaded drawer.

I’m sure the boxes are pretty strong but
that’s not all there is to it with making drawers.
You have to consider hardware compatibility,
because concealed drawer slides are designed
for drawers with recessed bottoms. Also,
when cutting from sheets of plywood in
making small, shallow boxes the miter
folded drawer box may be cost effective,
but in making full-sized kitchen drawers it
may leave large pieces of plywood left over
due to the size of the blank. Making drawer
sides out of ripped plywood is nothing if
not economical. Miter folding the entire
drawer from one piece undermines the
economy of the 5-part drawer box.

It looks like a very expensive novelty. a solution in search of a problem.

As already mentioned, the joint is mostly end grain, which is inherently weak. It would be okay for plywood but absolutely not for solid material. It seems to me that the setup would be like the far superior lock miter joint – which is to say it isn’t worth it, in most cases.

Have your say...
