On Friday I sealed the canopy perspex with silicone and left it to set. The waste material was removed with a plastic scraper.

And cleaned off with some methylated spirits.

The result is good but not perfect in a couple of places so will need some attention once the canopy is mounted.

Next up is to connect the NACA ducts to the various intakes on the carburettor and cabin heater.

The SCAT ducting for the air intake is secured with a jubilee clip onto the air intake.

The ducting is cut to size and attached to the rear of the righthand NACA inlet on the lower canopy.

The heat exchanger is positioned and secured in place with large jubilee clips.

A short piece of ducting is installed between the heat heat exchanger and the heater intake that runs through the firewall to provide cabin heat and a de-mist facility.

A long pice of ducting is connected to the heater control and will eventually connect to the glare shield that includes the de-mist vents.

The lefthand side ducting runs from the NACA inlet to the middle heat exchanger connection but it’s quite tight so it must be routed so it doesn’t come into contact with the exhaust system.

A spring is cut and installed to ensure that the air intake is supplied from the cold air vent by default.

One of the items I picked up on Monday was the pitot mount. I’ve already taken delivery of the avionics so I can mount the pitot onto the mount.

Instead of drilling holes and using screws I’ve decided to secure the probe into position with silicone which will provide a neat solution.

Once filled with silicone it’s left to set overnight.

The carburettor air box has two ‘horns’ that the SCAT hose connects to. They require sealing with heat resistant silicone and secured with three rivets.

The finished air box which will be left to set overnight.

The cabin air vents are supplied with fresh air from NACA ducts in the side of the fuselage. They require installing in the instrument panel and then connecting up with some scat hose. So a temporary fit of the panel is required to get the hose length.

Two brackets are clecoed into position and the panel is secure by two screws each side.

With the panel installed it give me an idea of the space I have for the avionics and possible positioning. Tomorrow I will fit the air vents and hose.

One job left over from installing the fuel system is to fit the fuel pressure sensor. The sensor cannot be connected directly to the hose. A 1/8″ NPT female to 6mm barb adapter is required.

As it will come into contact with fuel Loctite 577 is used to seal the thread before fitting.

The pressure sensor and adapter before being screwed together. They will be left overnight to set.

The final job for today was to trim the cowl to ensure is doesn’t come into contact withe the water radiator.
