Hi Doug,
The following expresses some of my experiences. >I plan to construct my own insulated EMC test table for a 5 meter chamber. >Seems simple enough to do and I could easily come up with something. I >thought I might first ask for input from those of you in the discussion >group who have experience or maybe even construction plans. Here are some >features I want: > >1) I will be testing products that weight up to 200 Lbs (91 kg). Standard 2x2 or 2x4 and 1/2" plywood should suffice. >2) I want to minimize metalic fastners. What I've used in the past are wood dowels and wood glue. This takes some time, but the table is extremely durable. >3) I would like to make it a pivoting table (not motorized). I have used a large lazy-susan mechanism (very low profile and w/ball bearings). Teflon pads were used to provide rotational stability and ease of rotation. >4) Height is 80 cm. Just cut the wood to fit. >5) The surface should be replacable if it gets badly worn or scarred. I'm >thinking of using hardboard. A round piece of 1/2" plywood should suffice (they can come pre-cut in 36" and 48" diameters). I've never had to replace a table top. >6) Suggestions on length & width? I would not recommend any horizontal dimension greater than 60" for table stability. All this material is commonly available and can be purchased at places like Home Depot, Lowes, your local lumber retailer, etc. As a convenience for measurement repeatability, I placed angular markings on the table top in 10 and 45 degree increments. I hope this helps.
