| Post subject: | Carb Air Box |
I have decided to try and build my carb air box per plans, rather than buying the Vans air box. If I buy the Vans airbox, I'll have to cut up my lower cowl and re-fiberglass it to make the Vans air box fit. I have looked through my plans, but I cant seem to locate what material is used to make the airbox. Anyone know what material is used? |

The more I look at it, what drawing # lays out the dimensions of the airbox? I must be missing a print.... |

well, eat my grits. I have been staring at #781 for 2 days. I cant believe I didnt see the dimensions. When I get ready to make the 751 seal, your gonna have to educate me as to how you make the fiberglass/silicone mixture. |

Sorry dude , I don't have a clue how to mix the goo as I didn't use this type of air box . You can probably use an off the shelf ready made seal material from Spruce , Wicks etc. RB NX115RX |

I cut my wings today for fresh air vents next to the fuselage a la Bob's method. I'm looking forward to cool air blowing me away. |

Is there anyway you could post pictures or drawings of your work. I have folding wings and really like the simplicity of wing vents. |

I cant add pictures/documents for some reason to my posts. It keeps telling me "could not upload." But, go to this link. Its a thread on this site about the same topic. Bob Highley posted a photograph document that I followed. Too easy. viewtopic.php?f=30&t=7646&hilit=fresh+air |

| Post subject: | Carb Air Box |
For those of you who have the "per plans" carburetor air box, would you please post some photos of your completed carb air box? I am having trouble getting this part visualized/built. |

     Note: my airbox is made with 3 pieces instead of 2 as shown on drawing -781 |

thats helps a bunch Bruce, thank you. I was having trouble understanding how the two (or 3 in your case) halves were joined from reading DWG 781. Now I see its a weld. |

| Post subject: | What should I do here? |
I cant decide which way to go here, so I am hoping you seasoned builders will give me your opinion. I am trying to decide which method of airbox installation will be the easiest path. I have 2 options: 1) Do I build the airbox per plans and hope it fits in my already built T18 lower cowl and scoop (if not, cut the cowl/reglass the scoop to fit) or 2) Do I use a Vans RV style airbox, cut the existing T18 lower cowl, glass in a Vans RV style air scoop into the existing cowl. |

Check the newsletters there's an updated air box design that will most likely fit in your cowl ... if not you cannot find it I have one in my shop I can take some pics for you replicate |
