Last chance.

“Take the blue pill and the story ends, you wake up in your bed and believe whatever you want to believe, or take the red pill, you stay in Wonderland, and I show you how deep the rabbit hole goes.” (Morpheus, The Matrix)

So you took the red pill. Very well. Its probably easiest if you either print off the Ezee mitre blog or open a second browser window (not just a tab) for it and tile this one and it side by side on the screen.

Most of this boxes construction follows the standard Ezee Mitre technique with the exception of the following:

1. The size of the board is twice the height of the box plus the length of the top of the box (no allowance need be made for separation cut). In this case its square so both length and breadth of the board are identical.

2. The box bottom/top separation cut method and the lipping employed to locate the top on the bottom are different.

Once you have performed Step 1 and cut the slot for the base you break off from the original Ezee Mitre blog before cutting the slot for the lipping.
The board now looks like this.

What you are going to do instead for Step 2 is to cut a double mitre (like the one which is at the joint line for the sides and the top in the Steps 3 and 4) all around the board, centred at where the cut separation line for the box top/bottom will be.

You cut this double mitre shy of the depth of the board by 0.5mm. Like this

This last 0.5mm is cut straight through with a knife. Doing half of the cut at a time and taping the join on the outside side of the board to conserve the original alignment of the side’s top to it’s bottom.

You make a triangular lipping insert for it like the one in this diagram.

In this diagram a section of a box side is seen with the triangular lipping piece in place. The blue lines are where this lipping is glued into the double mitre. The red lines are not to be glued and to this end are waxed before the insert is glued into the board. The left side of this diagram is the outside of the box and the right side the inside of the box.

This is effectively two pieces of wood rebated to half width for the end 2mm and then mated. The whole issue masking taped on what will become the inside and then cut into a triangle.

The lipping insert.

This is what the board looks like after the lipping mitres are cut (the new step 2) and the lipping is installed.

You then return to the original Ezee mitre technique blog to complete the box.
The next step being to cut the top/side mitres.

After steps 3 and 4 the board looks like this

After Step 5 the board looks like this

You then remove the masking tape from the lipping on the inside side of the board and complete the remaining steps of the EZee Mitre blog with the exception of step 8, which you miss out entirely as the box when made should seperate top from bottom, naturally. Well you might need to persuade it a bit if some glue has crept in in the wrong place. The waxing should have overcome this problem though.

Thats all folks

Be seeing you.
