2:39John machines brass hexagon bar into a fuel-injector adapter, cutting threads and reaming the central hole.
10:16He drills and taps the adapter, then cross-drills fuel holes in the injector nozzle tube.
14:33A motorbike coil produces a continuous ignition spark, demonstrated in normal lighting and darkness.
15:37The ignition box and fuse block are mounted and wired with safety relays.
18:59The outdoor starting attempts begin, with a leaf blower supplying airflow.

A leaf blower provides the airflow; John's homemade turbine supplies the noise. After machining the fuel-injector parts and wiring the ignition, he takes the assembly outside for its first starting attempts, until the engine ignites and spools up.

"WED 123 DIY Gas Turbine First Start Up." is the most watched of doubleboost's three new uploads, with just over 6,200 views. It is also the channel's busiest individual video right now, drawing substantially more daily views than either instalment of Sunday's furnace-and-burner build.

The payoff comes after plenty of proper workshop time. John turns brass hexagon bar into an injector adapter, checks its fit and drills the nozzle's fuel holes. A motorbike coil supplies the ignition spark. He is frank about the less forgiving parts of the project: losing oil pressure, he explains, means "goodnight turbocharger". Viewers are asking for RPM, exhaust-temperature and thrust readings, while others are already suggesting an afterburner. On a channel whose archive includes a jet-powered kart, that last request has history.

The broader week was steadier than the turbine soundtrack: around 30,000 views across the channel, daily viewing a little below its usual level and no net change in subscribers. That weekly audience was close to Becky Stern's, while Heart and Home Crew had a much busier week among nearby-sized DIY channels.

Sunday's paired uploads keep the other hot-work project moving: "SNNC 667 P1 New Furnace Build , Castable Refractory." covers the furnace build, followed by "SNNC 667 P2 Burner Build". Both have drawn several thousand views, giving the turbine's first start some suitably furnace-shaped company.
