the table top is supported by a central pole.
the string evens out the load on the table top.
the higher the tension the more rigid the table...
provided the central pole can support the tension.
Step 1: Materials ( not shown)
2 inch wood screws
para cord (or other strong string, or cable)
17x eye screws
1 inch pvc pipe
old satalite dish( if you dont have one of these just use some plywood)
small table top(also can be substituted with plywood)
Step 2: Drill holes
and insert your pipe...
must be a tight fit or your table will be wobbly.
Step 3: Attach plywood to dish
just drill a hole 3/4 of the way through your wood and insert the pipe into it.
to keep the plywood and the pvc pipe in place i just used a single large bolt and placed the pipe over it.
Step 4: Attach eye screws
Step 6: Adding tension
pluck the strings all the way around and if you hear the same high note throughout all of the strings you've done it right.
