Brief Description: Engine Preparation 6 - Cabin Heat Valve

The heater valve for cabin heat is the next part to provision on the firewall. This needs a 2 inch hole in the stainless steel firewall. This took a while with a hole cutter. Secret to cutting stainless is go slow, use lubricant, keep bits cool. I painted the heater valve Lycoming Grey too.

Clamped wood to back of firewall

2 Inch hole saw. Smooth hole

Painted vent
