19th August 2014 - Cabin and Carb Heat Muff - part 2

The 2" holesaw that I had ordered arrived today so I was able to drill three holes in the heat muff. Three lengths of 2" aluminium tubing were cut and welded into the holes. This completes the heat muff. 2" scat tubing will be used to plumb up the air intake (bottom right), the cabin heat (bottom left) and the carburettor heat (top left).
