All Replies on How do can I invisibly make this attachment?

Dowels would work, or putting threaded inserts in the top and hanger bolts in the columns and then thread the columns onto the top, then dowel that whole assembly to the case.

Through shouldered tenon?

I would put one or maybe two screws in from the underside into the bottom of “columns”. You could do this in a way to make the top easily removed and re-assembled if you like. This would make the entire unit easier to move if necessary. To do this, put threaded inserts in the bottom of the columns and then use flat head bolts with heads countersunk. They won’t be seen, especially if you have doors on the unit. Then use a large blind dowel or two smaller ones in the top of each “column” to mount them permanently to the top.

I would have probably used short mortise and tenons on both ends but if your columns are already cut to length, too late for that :-) My second choice would be dowels on top and threaded insert to attach it on the bottom.

Dowels would be easiest to fit, floating tennons easier to align.

Can’t quite make it out from the pics, are the columns attaching to the wallnut insert in the top?
And if so is it thinner than the edge or the same thickness?
(thinner would give an option of an angle bracket inset under the top going from the column to the maple.)

I like this idea. Not sure where to buy just a small quantity.

I’m not sure I totally follow what you’re saying. The walnut top is a bit thinner than the maple trim around it. That would hide the top of an angle bracket. But the bottom half of the bracket would be visible.

Loose tenon. Ask around and see if you have a buddy who has a Domino: you can knock out all of those joints super fast, accurate and strong, but you can also do loose tenons yourself with a router and a piece of hardwood.

I just ordered a Sample Pack from Knapp connectors. Thanks.

More one of these, so the entire thing is hidden by the lip of the top

A normal angle bracket would do, picture seemed the easiest way to describe the orientation

Biscuits would work. Based on the size of the columns you could use two or more biscuits per column. Alignment and installation might be easier than lining up and drilling for dowels.

Threaded inserts in the top and attach column with a hanger bolt. Attach columns to lower unit with a large wood screw.

Although those look like they work nicely i would feel like i was making ikea furniture with those lol

I have always wanted one of these. The INVISE MX2 is a devise that fits into the end of your drill and spins a magnet inside a square plastic cube causing the special fastener to tighten that is inside your joint. Probably not in your budget, $464, but it is something to keep in the back of your mind. It is perfect for what you want to do. This is made by Lamello.

I hear you, and I feel some of that. But, I used a biscuit joiner and biscuits on the top, I’m using Blum hinges for the doors, I used metal screws to attach the legs to the carcass, etc. So, I’m okay with using metal compression dowels to make an invisible attachment.

We usually bolt the bottom of the column, but just place or slightly silicone the top. Ours are usually glass.

You want the top as a decoration, not as a place to lift.

You could easily use this kind of option…there are many options available
