Why did you need the filament xfmr? Was the hot-wire so low in resistance?
Curious about the bent hacksaw blade tensioner.. was it bent in a zig-zag
fashion, approximating a spring of sorts, using the holes on each end to
connect it?

On the top end, the wire was attached via a long-ish turnbuckle to an

wire penetrated the work
surface (a table made of two 4x8 sheets of plywood) near the center

secured somewhere beneath. The turnbuckle up top was used to set tension

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.
