      So the big 'bazooka' propane nozzle will probably do the trick?
      =====================
      Prolly will, but if it 'resists', try the old trick of putting the workpiece in a small open 'oven' made by placing a couple of dry bricks to make an L shaped corner on top of another brick.  Helps contain the heat.  You need to get copper up to red heat before the silver solder will run and wet properly.  All joints should be a good fit, as silver solder needs that to suck in properly by capillary action.  Ordinary solder joints can be sloppier.  Be careful if using brass as this tends to slump very quickly if the temperature gets only a little bit above that.  Be sure to use a good silver soldering flux.

      ... silver solder for a stronger joint? if you make an EL column you can get away with weaker solder since it doesnt need much structural strength since all

        if you make an EL column you can get away with weaker solder since it
        doesnt need much structural strength since all the weight is acting
        down the middle, (bottom must be strong). offset stills can have a
        large lever/moment effect at the top so you need strength. just like
        its easier to hold a large bag close to your body rather than with an
        outstretched arm. EL is easier and cheaper to build for most too.
