	Unfotrunately, what the client wants is what counts. :(

	Excellent technique and it certainly makes for a stronger
	joint than those which I recently offered.  Use 36 ga
	copper sheet.  Joint will be perfectly strong enough but
	the thin sheet will not add enough thickness to be noticeable.

	Whyzat?  I would tack at the two ends, then starting from the
	middle, work my way toward each end in turn.  Leaves both
	hands free and allows for applying pressure to the soldered
	joint while still fluid.
