On the top end, the wire was attached via a long-ish
turnbuckle to an
insulator secured to a ceiling truss. The hot wire penetrated the work
surface (a table made of two 4x8 sheets of plywood) near the center
(passing through a metal guide plate with a small hole) and was firmly
secured somewhere beneath. The turnbuckle up top was used to set tension on
the wire.
I've got one in my shop made with stainless steel music wire and a bent
hacksaw blade for tension. A cheap triac dimmer feeds into an old
filament transformer. Not as grand as yours, but it does get the job done.
