year Since building season us thought Id pass along article Duane Gall putting firewall Its Colorado Competition Society newsletter Over Duane Life tough youre kitmaker After year two R&D carving fuselage plug making mold testing prototypes etc finally get point can lay up decent fuselage cut some wing cores couple evenings its bad enough told charge too much stuff its worse proud owner secondhand kit calls up middle night say Hey Im afraid try put firewall thing Can bring over have Believe possible prefab part assembly would installation firewall fiberglass fuselage some thing has done custom No two mod elers share same taste engines mounts throttle/shutoff installations fuel tanks etc just too variables allow process standardized Admittedly youve never done before thought attacking shiny new fish Moto-Tool kind scary theres first time everything nobody ever did anything hadnt done before us would would So heres its done Start en gine engine mount spinner bolted gether neat little unit propeller isnt nec essary stage may get way Ditto muffler Take long moment decide side fuselage engine will stick Out draw approximate size shape necessary hole marking pen Set engine assembly next fuselage spinner backplate lined up nose ring determine far back engine mount ex tends will approximate location firewall youre done Put some marks too reminder Now disassemble engine mount spinner goggles Moto-Tool fired up cut hole just big enough engine slide stick crankshaft through nose ring Bolt spinner crankshaft worst part now over front nose ring has flash other irregularities sand flat spin ner backplate will fit against snugly inter face will determine thrust line take care sand crooked Now get engine mount hand slide position behind engine accessing through wing saddle area radio access hatch depending what sort airplane Bolt engine may have enlarge engine cutout point accommodate bolts bolt driver Its time firewall some kits firewall will nicely precut others youll have some cutting trial fitting yourself case goal have firewall slide behind come gently stop touch ing uniformly around inside fuselage just contacts back engine mount doesnt have perfect does have sit flat against engine mount Get some masking tape firmly tape spinner place against nose ring maintain proper alignment engine mount should now suspended inside fuselage en gine cylinder free swing few degrees viewed front rides crank shaft bearings doesnt look bind ob struction somewhere get rid Anything gets way proper thrust alignment now will just cause headaches later Look OK Good Now holding en gine cylinder just way want press firewall against back engine mount sneak couple drops instant glue interface its cured unbolt engine mount pull mount/firewall sembly out way came Without removing mount firewall drill mount ing holes plus holes throttle pushrod fuel lines etc install blind nuts mount Pop mount loose sand away ex cess instant glue apply small amount Vaseline wax back mount fa vorite fuelproofing goo firewall bolt mount firewall will permanent Now havent already done clean inside fuselage alcohol acetone sand lightly glue will stick Once again slide mount/firewall assembly place bolt engine Remove tape holding spinner against nose ring persuade assembly forward another /16 allow spinner turn freely tends increase available horsepower Keeping spinner aligned nose ring drop stant glue around outside edge firewall tack place point like pin firewall place toothpicks extra securityallowing take engine out next step fear accidentally knocking everything Out alignment pin firewall drill 5/ holes outside through fuselage material firewall various points around its peri meter install cut-off toothpicks holes instant glue Five six toothpicks will usu ally next last step youve probably guessed goober up firewall-to-fuselage joint favorite bulletproof permanenttype installation material like use slow-set ep oxy eg Hobbypoxy Formula 2 small pieces 4-oz fiberglass cloth applied both front rear using disposable brush Just couple additional notes some rac ing planes rear-exhaust engines may need add exhaust channel usually made /64 plywood after firewall before giving final epoxy-and-glass cloth treatment way can reinforce fuelproof channel using same batch epoxy Im us ing firewall thus make whole front end integrated
