Topic tags/keywords: sliding dovetail box joineey

Hey y’all,

I’m building a sliding dovetail box and I’m trying to figure out how to get a bottom in there. I’ve already cut the ¼” dado in the bottom I just can’t figure out HOW to get a bottom in there, since the joint prohibits being able to slide it in.

Does anyone have any suggestions?

Maybe post some pics of it and what you are trying to do? I’ve mainly only seen boxes where the lid is a sliding DT

Yes, a picture or two would be very helpful. I can’t picture what you’re talking about. Where exactly is the sliding dovetail?

My guess is the sliding dovetails are the joints for the box, running vertically. If that’s the case, the only way I can think of to get the bottom in there is to slide it in before the final side is dropped down. Since the bottom would block the side, I suppose he could make the groove in the opposing side deeper and cut the bottom such that when fully inserted it is out of the way and then slide it back in place after the side is down.

You’d have to make the groove wide enough that the bottom can be slid over and find a way to pin it in place afterwards.

Now I’m tracking. I’d make the dado on two of the sides a rabbet instead. Or, notch two of the vertical pieces at the bottom so they rest on top of the drawer bottom.

I posted my comment before seeing the photos. My suggestion won’t work due to the posts. You’ll have to modify it so the bottom can be dropped in from underneath. Cut some strips to trim it out.

Guess this is going to be my best option, I might need to trim to just above the dado to get rid of it. I was just in regular box mode and got to this part and was like, “well that’s not gonna work” thanks for the input guys

I would notch two of the vertical pieces;
slide the bottom in;
drop the last side;
patch the two notched vertical pieces if really necessary.

Take 2 of the posts, chisel out that little square under the groove.(unless there is enough play to where you can “bend” those out pf the way. Make the bottom of the” front” a rabbet. Slide the bottom into the groove in the 3 sides, then slide the front and 2 posts down into place.

You don’t. Given the box size a butt joint will work. You’ll have the dado showing unless you want to cut the box down.

Tip: Design the entire project ahead of time instead of sitting down at the saw and noodling.

Most of the comments are helpful and not made from a lofty position.

Just a little brainstorming but, maybe consider a 3 piece bottom, maybe with a contrasting middle piece. (That piece of walnut off to the side looks like a candidate). The two outer pieces could be slid in and the box assembled and the two outer pieces slid into place. The middle strip would not engage the grooves but be an exact inside fit. I can think of a few ways to be able to clamp the middle piece in. I’m assuming you’re using a solid wood bottom. Edge gluing the long grain edges together would be plenty strong.

Creativity shouldn’t be planned in my opinion. I’m not putting ikea furniture together I’m building something from scratch. No instructions necessary. I’ll let you know how it turns out.

For sure. Calling your performance piss poor is pretty rude. We’ve all designed ourselves into a corner at one time or another. Caca pasa.

Dado inside of all 4 verticals, assemble all, inc bottom, at once

or

nip height of verticals, glue, screw, micronail bottom onto nubbed verts

Creativity starts on PAPER. If you just go sawing away randomly looking for inspiration you’ll wind up with sawdust and kindling.

The design decision to use sliding dovetails instead of straight tenons makes the bottom impossible to insert into the dados.

The only solution is to change the (faulty) design.

You can’t cut the bottom off one end as the corner posts will block it from siding.

You can toss the dovetails and make a conventional tenoned box.

You can butt joint the bottom but this leave the extra dado showing on the inside. Or you can use a thicker butt joint bottom to cover the extra dado. Or you can shorten the box to eliminate the dado.

If you clear cut the insides of two of the posts so they end in a rabbet instead of a dado you might be able to cobble it together. But the errors will show.

As a design engineer the creativity happens on paper. If you have to pay for labor and spoiled materials you do not just try to unthinkingly cobble designs.

Everything should be drawn (back of envelope is ok) before you start to:
  • Prevent errors like this
  • Establish design copyright
  • Document the design in case it sells and you need to make more than one
  • Accurately estimate materials and process flow

You skip these steps at your own peril. Again the 6P’s apply.
