[Noisebridge-discuss] let's get a TIG welder

[jim]

    This is a scary prospect. The building is wood, the 
frame and floor are old and dry. hot metal drops hitting 
the floor are on the order of three or four thousand 
degrees Fahrenheit, much hotter than molten solder, and 
take much longer to cool. Wood can ignite at many hundreds 
of degrees. 
    Seems to me a bad idea. If you do it, please be sure 
that beneath the metal floor there are three inches of 
concrete and maybe another metal plate beneath that. 
    Also, be sure there's protection at least one foot 
above the floor on the walls (metal over double gypsum 
on metal studs).
