Well the top shell glue up was successful but I’m not going to show you yet, you’ll have to wait. Its good. Well I think so. Next we need to make the bottom shell. First we’re going to need some measurements. Width

92mm (you can do the maths, divide by 25.4 or multiple by 100 and divide by four for an approximate figure) and depth

51mm. To make the actual shell a tight fit I subtract 1mm from the width making 91mm (fold up and glue line add a tiny fraction almost making up this millimetre). I also add 5mm to the height as there is going to be a 6mm plinth attached around the base of this bottom shell. So thats +6mm -1mm = 5mm (so that it just doesn’t touch the inside top of the top shell). This allows for calculation of the board size as 2 x height + width (you’ll see when I mark it out) that is (2×55) + 91 = 201mm.
As its a square box you’d expect this to be 201mm square, wouldn’t you. Life is never that easy. Always measure both width dimensions. This one is 201×201.5mm. Usually I make these bottom shells from 3mm Birch aeroply. I feel adventurous this time and there was some sycamore left over, which I re-sawed and glued up thus

Cleaned up and thicknessed to about 3mm on the drum sander it looks like this

It never ceases to amaze me that two knot holes on book-matched wood looks like a pair of eyes. Can’t figure the expression on them this time though. For even grain coverage on the finished shell I mark up the net for it at 45° to the grain direction.

See where the 2 x height + width comes from? This is trimmed down and taped ready for EZ-mitre

The bit in the router here is the same 45° bit I used for the mitres in the top shell. After whizzing through all four sides it looks like this

The four corners are chopped out with a knife

and the result folded up, glued and taped to produce this

In the next part we see how well it fits. Adjust as necessary and add the plinth

Be seeing you.

Can’t wait to see it. The tutorials are meant for someone other than me though. My idea of precise is, “looks about right”. -- I just got done cutting three boards and all four of them were too short.

It just seems to fall together. I can’t wait to see the finished piece. It looks like it is coming along great! Sheila -- Designer/Artist/Teacher.

You need a wand to tap three times. And you need to fix the spelling of miter.Steve -- -- I'm no rocket surgeon Spoontaneous1334 posts in 3386 days #4 posted 07-24-2011 01:30 PM Uh, my wife just corrected me. She says the eyes belong to an elephant. ....she may be right. -- I just got done cutting three boards and all four of them were too short.

Also, most of the magic wands I’ve ever seen look just like sticks, I’ve got lots of sticks. There’s my two pet peeves over with.

Dark_Lightning3171 posts in 3165 days #9 posted 07-25-2011 02:43 AM Plenty nice work. I’ll have to file the serial numbers off that E-Z Miter technique and try it for myself one day soon. Those are elephant eyes, in my mind. Now, I hear from one of my sons that the elephants in Africa have discovered alcohol and are tearing into drinking establishments and drinking the places dry. Those knots look like what I would imagine a stonkered elephant’s eyes would. Also, the whole phenomenon of seeing eyes at all in the board is described here: http://en.wikipedia.org/wiki/Pareidolia -- Random Orbital Nailer
