I agree with the previous responses. ESD material does wear out, especially in my dry climate. It has to be replaced once in a while. In commercial operations is is tested on a schedule and discarded if it does not pass. It has to be conductive enough to keep parts from damage and resistive enough to not allow a shock.
I would like to offer another option. Home Depot will sell you workbench legs, I bought these but they have several sizes. They were shipped free http://www.homedepot.com/p/Edsal-33-in-Adjustable-Height-Workbench-Legs-ABL30/204417821;jsessionid=E3520EC0F5BF7CC72323A1EF2F5C2DE0 http://www.homedepot.com/p/Edsal-5-in-x-72-in-Work-Bench-Stringer-ST72/204417825 I then laminated 1/8 masonite on a solid core door, routed the edges and put oak edge banding on just for grins to make the bench tops. I also but blocks under the legs to make it taller for a stand up bench. Take a look at my qrz.com page for pictures. It saved a bunch of money over a standard lab type workbench and I had fun making it. A standard countertop or similar would go on the legs easily, they just screw onto the bottom. The legs are very sturdy. I just put ESD mat on the work surface area. The edge banding was not the best idea, it tends to chip easily. I connected my ground system to the metal legs, maybe it helps as a counterpoise, maybe it makes no difference. 73, Mark W7MLG On Sat, Jan 23, 2016 at 6:28 PM, Bob McGraw K4TAX <[email protected]> wrote: > Places such as LOWE'S and HOME DEPOT carry stock counter tops.

I have used one for years. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
