Fuse (cont)
Vents for the bottom of the fuse.
Went to home depot and picked up some stock aluminum sheet for vents, some foam to stiffen the inside of the belly pan and some brass water heater hose for the moki's exhaust.
Engine Exhaust vents:
Made a paper template first to check functionality and then cut vents using the aluminum sheet stock. A wide mouth pair of vise grips worked great at bending the sheet aluminum. Nothing complicated: the opening is 3/8" wide that tapers down to zero width and a 1/4" lip around the edge for some #2 button head wood screws to secure the vents to the fuse.
A forstner bit used to drill a hole in the flat sheet sock for the exhaust pipe with the two vents attached.
Vent in front of turbo-charger vent.
Same design as for the engine vent only a little larger. For vent louvers I got some corner flashing that had ripples but didn't like it's looks, once cut and put on the fuse so I just took sheet stock and bent it 1/4", 1/8", etc until I had a four opening vent louver. I had to sand a flat spot on the fuse so the louver would sit flush. A dremel cut off disk was used to cut slots in the vent louvers. I also added side sheeting to the vent to cover up the end holes.
Side vents louvers:
There's also some side vents on the bottom of the fuse. Same as the previous vents only a little smaller.
Turbo-charger vent:
A block of balsa was used to get the rounded end of the vent. Stock sheeting was then screwed over one end of the balsa block to complete the turbo-charger vent.
