Metal Casting at Home Part 90, Waste Oil Burner Part 1

My furnace burner has been redesigned for simpler construction and easier dismantling. My original used a Hago siphon nozzle that I had to import from the US. The shipping, custom charges and VAT on the import meant the part cost around £65.
The new design uses a nozzle that was £12 including world wide delivery.

Parts were printed on a Sovol SV01 printer : https://sovol3d.com?sca_ref=895359.hScoXg1y01
