Gaps



My gap is a series of brass drawer pulls and its just too much aggravation to
keep it clean. They carbon up quickly and have to be sanded then reset. I
read about a gap Tesla made, something on the order of two blocks of metal
with holes drilled in such a way as to cause them to draw air through them
when they started heating and it keeps them fairly cool. They are set close
together and I believe he wrote that they functioned very well. Is anyone
familliar with the design? If I can I would like to try it or if needed have
a machine shop mill some out.    Stephen Sanders
