How long would the blind tenons be if my timber is 1 1/2" square? Won`t they hit each other in the middle?

You can either mitre the blind tenons or offset them.

Here's a sketch of what it could be done like, the height is not to scale only had room for about 1000mm on teh A4 paper.

The tennons could be mad elonger and go into mortices but I've shown them at about 10mm long to match a 10mm deep glass groove. The back just has a wider groove to take mirror plus MDF/PLY.

to stop it looking over chunky I've split the front down the middle to give a door frame approx 1 1/2" x 7/8" and teh same for the front frame.

I just wanted to say a big thanks Jason for the time taken in doing the drawing for me. It has helped lots and has also changed my plans to make the case more in line with what you have drawn.

I have just been down stairs to have a practice at the joint on some scrap offcuts only to wake up by my wife and daughter so sadly, despite doing all my metal working in the late evenings, woodworking appears noisier and has been banned after bed time! The is going to cause this case build to drag on for even longer! I`m away with work from Monday until late next week so it`ll be late next week before I even have my practice now!

On a different note, I did manage to take some photos of my wood to see if anyone can identify it. like I said, I`m not very keen on it. It was sold as Maple but it doesn`t look like it to me or the carpenter that cut the plank up for me.





Here is a piece of redwood/pine just for colour comparison


The story goes that my wood came from a yard in wigan which closed down but was an importer of exotic hardwoods. Any idea what it is?

just an observation Chris - I don't know how long it is since the board was ripped into those rails, and where it's been kept since - but it may be no bad thing for some time to elapse to let it settle. Ideally, it should be left to acclimatise in a location with similar temperature and humidity to its eventual home - so whilst you're away, you could leave it with a clear conscience!

it is not maple, I would stack it nice and flat with sticks between and not touch it for at least a month and see what shape it takes and what opens up, although I am a time served joiner i have been out of the trade for a long time timber spices seem to change over the years , what we wouldn't make pallets out of is now used for fine furniture, but one thing is for shore that is not what I call maple.
as you are going to put a lot of effort in to the case I would look for some old table tops from schools labs /tables/shelves  etc I got some at one time and it made a very nice table.
