Throughout this instructable, I will offer suggestions on how to improve my design.
Step 1: What You Need
11x14 piece of plywood
3 hex type 1/2" bolts
3 nuts that fit said screws
command adhesive strips ( Could Substitute with double sided foam tape)
11x14 sheet of double thickness glass (Could Substitute with marble slab, or single thickness glass)
Electric drill with bit that is slightly smaller than the nuts you intend to use
Optional (but recommended)
2 Part epoxy (15 minute kind)
1 metal nail
Small 'bumpers' (the things that keep chairs from scratching the floor)
Step 2: Measure Twice, Cut Once
I was using scrap wood so I had it cut down. I would recommend plywood as your wood material. Its cheep and won't fall apart like particle board.
Be safe with power tools!
If you don't have the ability to cut wood, Home Depot will cut down boards to size. I recommend using standard photograph frame sizes such as 5x7, 8x10. This will make choosing glass easier.
Step 3: Setting the Leveling Legs
Measure the diagonal width of the nut and use a drill bit that is slightly smaller. Drill a test hole on something you don't care about, and if getting the nut to fit in will require a hammer, then you've got the right bit.
Take your time drilling and use your ruler to check the depth of the hole. We want the nut to be flush with the surface. Only drill as deep as you need to.
Place the nut over the hole, and gently tap it into pace with a hammer.
If you don't have a bit that will be a good match for your nut, then in step four I'll show you how to use epoxy to compensate
Step 4: Leveling Legs Cont..
I drilled a larger hole than the nut. I then carefully covered the back of the nut with tape. This is to prevent epoxy from getting into the threads.
I squired some epoxy into the hole then mixed it with the nail. Once well mixed I partially threaded the bolt into the nut and set it into the epoxy filled hole.
Causing the epoxy to over flow is ok, but don't let it get onto the bolt or inside the nut.
Step 5: Sanding/Painting
This would have been a good idea to do before glueing the bolts.
I painted the board white to improve visibility in the darkroom.
Another great idea to do before setting the nuts in.
To keep the nuts from being clogged with paint, I cut small pieces of tape and placed them over the nuts. I gave mine 3 coats, and its not perfect. But I build this for my own use in the dark. I don't think i'll demand a refund ;)
Step 6: Getting the Glass
I have the tools to cut glass so I will be recycling a broken entertainment center glass door.
With my ruler and sharpie I draw out the size of the glass plate I need. Then carefully score the glass and use special pliers to break the glass upon the score line.
I used 220 grit sand paper in a sanding block to remove the sharp edges from the break. A knife sharpening stone will do the same thing. Be careful to avoid breathing in any of the glass!
Step 7: Mount the Glass
One strip in each corner, and then with careful placement lower the glass.
Keep in mind: You can clean the bottom of the glass before its mounted but not after.
Step 8: Mount the Leg Booties
1. Protects your surface
2. Keeps the table from sliding around. Now it kind of 'sticks' to the table.
I recommend using hex bolts because their flat surface makes adhering the bumpers very easy.
Step 9: Done!
Now pour some plates!
