How to design cabinets with double rebate joints

This is just a very short article to answer a question from Richard who asked me how to join two panels with a rebate in each panel.

Designing a double rebate for a joint on a cabinet – or for any joint – with Polyboard is a very easy process that only takes a few minutes to do.

The short video below gives you an overview of this process, as well as a visual representation of what this looks like when you use Polyboard software to do it.

We’ll start by taking a simple cabinet in Polyboard. With this type of cabinet, by default, the top and side are just joined by a simple butt joint, with the sides placed together without any special shaping. There are no assembly details at all.

The first step is to modify the link and the relationship of how the assembly details at the top link to the side. To do this, you need to go into the links menu and look at the properties of the link. Then to make a rebate, you need to change the type of link to a mortise and tenon joint. The depth will then be the penetration of the top into the side, and the thickness of the tenon is by default the thickness of the board, so it’s just as if we have a rebate on the side.

To then give the cabinet a double rebate, we need to diminish the thickness of the tenon. To do this, we have to change the position of the parameter from the middle (which it is by default) to the outer side. This action then creates a rebate on the top and a rebate on the side, which is a double rebate.

    Many Thanks Ness, it worked perfectly and now we’re back up an running – probably headlong to the next event where I can’t figure something out.
