Hi George - really not enough information to work with. 3x3 is a pretty good sized area for the top of the leg but if the cabinet is 6 feet tall, it is likely not enough  for just glue. Are you working from plans? what do they say?

I am not working from plans. the curio cabinet is 4'high x 3' wide and 18" deep. if you think glue isn't sufficient would  2 or 3 wood screws and glue do for life of cabinet. or is there special screws or bracket for the legs on cabinets?

Doesn't look like it's all that large. I'd add a couple of wood screws for good measure though.

For a cabinet and legs, as described above,  

the leg joint needs to be rigid and ‘’firmly affixed’’, so that when the cabinet is tilted at a 45 degree angle from vertical, the leg will be firmly affixed, with no distortion/deflection in the cabinet or legs.

  If the cabinet is inadvertently dropped, while moving or handling, the leg should not deflect  and cause damage to the cabinet ---or ---

allow it to topple over and damage the contents or breaking any glass in the cabinet.

  I'd install a 5/16'' lag screw, centered in the top of the leg.

The opposite end of the lag screw, equipped with a 5/16’’ bolt thread,

that screws into a 5/16 '' threaded insert, firmly affixed in the bottom of the cabinet.

  Install the threaded inserts,  into 1x 4 hardwood stock, (oak or maple), running front to back.

Recess the hardwood stock so that it’s not readily visible.

Firmly affix, glue and screw, the 1x4 stock to the base bottom.

  With the leg installed, the flat top surface of the leg needs to ‘’mate flush’’ against the 1x4 supporting member.


thankyou that was a big help

This type leg support is readily available.

Commonly referred to as ‘’clinch nut plate’’.

Clinch Nut Plates

It features a 5/16 thread nut, that accepts a 5/16 threaded hanger bolt.

The plate can be secured with #10 screws

The pointed end of the hanger bolt screws into a pilot hole in a wooden member.

 Steel Hanger Bolts

.

Steel hanger bolts are ideal for easy assembly of a bolted connection on a wooden joint.

  I’ve used this approach with ‘’round legs’’.  

When used with a square leg, space needs to be allowed to rotate the leg during installing or removal.

Affix the plate to a 1x4 hardwood brace, secured to the underside of the cabinet.

  If the hanger bolt extends too far beyond the back side of the leg plate, for your design,

The threaded bolt can be cut shorter.

Apply a 5/16 nut, cut-off to the desired length, file off the unwanted burrs, and then remove the nut.

 

  Alternate style leg plate.

Hi George,

Take a look at this video from Kreg. I've built several tables this way and the joint is very solid. Good luck with your project!

Free Hand Guard (dust collection)

Hi.  I'm wondering if anyone has used the Woodpecker Free Hand Guard for dust collection on their bench top router table during pattern routing.  How effective is it?  It's adaptable to any router table.  Continue

New Kreg 720Pro

I saw the video Kreg put out for this new jig and had high hopes for it.

I purchased one today and am very disappointed with it.

First the docking station is extremely cheap. The plastic is pathetic. A Lego has more…
