Plywood Drawer Joint


Recommended Posts

I'll be building a few cabinets and drawers shortly for the shop. I prefer to use hardwood (either poplar or maple) for drawers normally, but I think to save time and get things done a little more quickly I'll use 1/2" plywood (maybe BB, maybe not...haven't decided). But here's my question: when I use hardwood my joints are either DT (for household furniture) or drawer lock joints (for cabinets). But what do you use for plywood? I can't imagine either of my other ones working all the well; and for the record I have tried to cut DT joints in BB and wasn't all that enamored with the results. Besides, I dn't want to spend the time...I want something fast. What about just using wood screws to hold the sides to the drawers front. These will be drawers boxes that have a false front.

Since they are shop drawers I would agree with Kelly. I would use pocket hole screws first and a locked rabbet second.

 

I have been using 3/4 on my shop cabinets for the beef. Having a roll-a-round shop with limited space I tend to load the drawers up with quite a bit of weight. 3/4 gives me a little confidence that when I pile four or five routers, containers of fasteners, etc. into a drawer the draw will stick together and not fall apart.

I just counted. There's 36 drawers in my shop. All BB. Most are whatever MM equates to near 3/4". The rest are the 1/2" equivalents. Those just hold small tools or paper. All the corner joints were made on the RT with Stick's posted method. It's probably just as fast or, faster to construct as pocket holes.

I have seen a lot of recommendations for pocket screws, front set hidden by the false front, back set hidden at back.  Never tried it.  

 

But I have use lock rabbet.   Or this with "belt and suspenders" approach.

 

In any case, definitely use glue.  I like No Run No Drip for short grain situations (1/2 of plywood edge)

To be more clear (maybe) the drawer lock joint to which I referred is the lock rabbit mentioned in most posts. I actually hadn't thought of pocket screws, they might be an option. My concern with the dado/tongue joint (or lock rabbet, or drawer joint) is that the dado in the sides just has short wood plies glued together holding it....maybe I overthought that too much. Thanks guys, I think I may go with the lock rabbet. Lew, the 1/2" plywood I have is Columbia Forest Products cabinet grade...it's a lot better than some stuff that's sold. I have 2 sheets of it in the stash, and 1 sheet of BB, the 5x5 stuff.

This is what I call a lock rabbet joint. Probably goes by several other names too.

I use glue and a few 23 gauge pins so I am not tying up my clamps.

 

I do the same w/ the 23GA..

here's rebated rabbets and the bit.. (Infinity)..

You can't go wrong with that, Fred. Once the glue dries they won't go anywhere.
