We are all cheap...
Since it is broken the most one can loose is their time.
Welding will get too hot.
Brazing maybe.
The Crack is 2 irregular shapes that fit perfectly.
2 low tech options.
Solder and epoxy.
Both require cleaning very well.
Soldering will require less heat, good Flux needed, it will require good soldering skill to get it to flow properly, silver solder better.
For epoxy good stuff needed, we have some HVAC epoxy suitable for fixing the coils, proper cleaning then forcing through by finger scraping on one side until it flows out the opposite would allow a good strong bond due the Crack.
After it cures for a few days clean up any mating surfaces, fix the screw and put it together.
Watch craigslist for replacement.
We have old 2 cylinder single stage in the side yard but madera a bit of a trip.
