Today I built a set of 3 cabinets with 3/4″ plywood. On one, I used dados, glue, and nails. On the second I used butt joints with biscuits and glue. On the third I used butt joints with glue and screws.
Glue and screws was sure a lot easier and faster. Are any of these methods (or others) significantly better than others?
Thanks.

i've built cabinets for twenty years and for joining casework, biscuits for the first choice followed very closely with partocle board screws
biscuits are more time consuming and cost more per cabinet, but screws require concealment behind a veneer or laminate covering
so for a typical kitchen, casework is fastened with screws except for where the fasteners will be exposed, then its the biscuit joiner
dadoes and all that stuff? forget it
I'd use pocket screws and glue before anything else. Biscuits a close second, dados are fine as long as you can control racking in the cabinet (i.e. have a solid back or strong face frame). Butt joints, glue and nails? No. Only way I'd use butt joints would be with glue and screws, maybe, or dowels, but not nails.
Even faster is pocket screws, no glue.
I don't think the joinery you use matters much -- in terms of necessary strength.
What does matter -- if you are building any number of cabinets over time -- is to find a system of joinery and stay with it. That's what will give you speed and efficiency.
I do all mine with a locked dado on my TS, but I have a system (with set up blocks) that makes the process very fast, and the cabinets are easy to assemble.
It is not that my system is any better, just that I am both familiar with it and set up to do it quickly.

I am with ya on dados..makes life and clamping a lot easier...I just plow a shallow dado, and use all the above methods in addition.

Im with ya on the dados , dados glue and clamping the way to go.
It automatically aligns the shelf plus I dont have to change my TS set up. i use a router primarily for dadoingLong Live REZ.........ROAR
Do you use a jig to make dados with your router?
Paul
Some times depending on the size of the panel . Its a shop made T square style jig. My router table has a sliding table with a fence on it so I use it quite a bit.. Ill find a link for it. I think MLCS sells it now and so does grizzly but when I bought it , I got mine from wood line.

I build lots of cabinets from birch ply. The material takes screws well so I use pocket screws only. If the joint is going to be in shear (for instance an end unit where the feet are inset to provide toe space) I use some polyurethane glue as well. More than strong enough.
If I was making cabinets from particle board I weould use a different joining method
John
Pocket screws where it doesn't show, biscuits where it does.
You and others use pocket screws. Are these coming from inside the joint? Why not just screws from the outside if they don't show?
Thanks.

Well, if you are using birch ply, then with a pocket screw fixing a base to a side then the threaded part of the screw will be entering the side panel from the side, whereas screwing from the outside of the cab with an ordinary screw you will be screwing into the end of the ply panel, which is obviously no so good. Same would be true with solid wood.

If you are attaching a face frame to a kitchen cabinet you can't drive screws through the front of the face frame. Well you could but it would be ugly. Pocket scews go in from behind at an angle drawing the frame tight to the box. if you used biscuits for the same application you would have to clamp it. pocket screws save a lot of time, and if you make a mistake, just take it apart.
