Leveling Table for Dry Plate Photography

I am getting ready to make my own dry plate negatives. One of the required materials is a small table that can be perfectly leveled and is made of a material that will cool the recently poured plate.

Throughout this instructable, I will offer suggestions on how to improve my design.

Step 1 What you need

Needed
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
Hammer
Pen
Ruler

Optional (but recommended)
2 Part epoxy (15 minute kind)
1 metal nail
tape
Electric sander
Paint
Small 'bumpers' (the things that keep chairs from scratching the floor)
