After a cup of coffee and muttering a few choice phrases, I tried my luck on the lathe again: success! I had to laminate a poplar wood blank to make the Afterburner cone due to it's height. Turned out pretty good if I say so myself. THese will be attached later after all the planking is completed and the Exhaust duct/flame-holder has been fabricated and installed. |

The finished master with my first attempt at forming the canopy. This is a totaaly new process to me: SLip the form into a soft-drink 2 liter bottle that has been cut off at both ends then apply heat from a heat gun and teh plastic magically shrinks the shape of the master. Cool! |

Next project is to carve the master for the canopy. I used Basswod that I picked up at the local big-box home improvement store. This is a progress shot about a 1/2 hour into the process. |

Here are completed main gears. They need to be cleaned up a little now. The grand plan is to leave these in this form until I have them mounted in the airframe and trued up then I will guzzie them up with plastruct tubing and othe do-dads to give them the correct appearance. |

It's getting interesting now. The main L/G of this A/C has a main support axle with 4 struts attaching it to the oleo strutt. Each of the strutts is at a different angle and lenght. I made the jig shown to be able to make sure that the gears are identical. The gears are made of various sizes of brass tubing silver solderd together. |

| Keep it up. An interesting build.

| Cut and fiddle, fiddle and cut. That's the way I do it as well. This plane is looking great. |

Here is the nose gear well that has been fabricated within the inlet duct. It has been really hard to find good detail photos of some areas of the A/C, so there ia a little "Imagineering" going on here. I also laid on five planks on the bottom of the fuse to keep everything lined up. I did not want to apply any more planks that this as I need to keep the main L/G well area open for fabrication. |

Impatience strikes! I just had to start fairing the planking to see how it was going to turn out. My little Stanley planes, which are older than I am, worked just fine once they were set a little deeper that what I normally have them. The soft balsa requires a more aggressive approch than pine or hardwoods. |

Really not good picture as my "shop" digital camera does not have a Macro mode. If you look close, you can see the rivets and foil joint lines. Still have some work to do fairing the duct into the AIr Inlet nossepiece, ( which I haven't fabricated yet). |

| WOW!!!.. I love watching scratch built projects. Looking mighty fine!! |

Starting to build the air inlet ducting. It is such a prominent feature that I felt that it had to be included. I spent several days re-learning the trig required to generate the patterns for the curved conical duct sections. Finally said the hell with it and cut and fir posterboard patterns until I wa satisfied with the shapes. There are three sections of inlet ducting per side. |

About a week later: The fuse has been removed rom the jig, which was modified to be a building cradle. The vertical fin has been sealed with Cabots "Quick-Dry" lacquer basec spray sanding sealer. In our new Eco-Friendly world, these high VOC items are getting really hard to find. The fin has been primed with a high-fill automotive rattle can lacquer. |
| rayl, Image # 32793 | 08 Jan 15 16:57 |
This is the third attempt at constructing the vertical fin. It's been a long time since I built a balsa model (about 50 years), so I expect to have bad days. The ribs are 1/8" and the sheathing is hard 1/16" stuff. |

Starting the process of planking. I had several bottles of CA glue from our local Hobby Lobby which I used to glue up the formers and longerons. When I took the clamps loose, everything fell apart! A two hour drive to Sioux Falls to the LHS to get some fresh CA solved the problem. I'm using 3/32" X 1/4" strips for planking. I plan on planking the entire upper half of the fuselage before removing teh assembly from the jig. |

Another view of the jig and clamps. My "other hobby" is woodworking and one of the truisms from that avocation is that you can never have enough clamps. |
| rayl, Image # 32790 | 08 Jan 15 16:43 |
Longerons and formers mounted on the alignment jig. Got Clamps? |
| rayl, Image # 32789 | 08 Jan 15 16:41 |
THis is the jig that I made to insure the alignment of the longerons. The longerons actually change elevation from the main spar back to the final former by about 7/16", thsu the jig. |

It tool me a while to get the features on this site figured out and Jim had to change something for me to get in. That being said, I ve actually been working on this thing for about a month, so there will be lots of pictures intially. Here are all of the formers, of 1/8" ply except for the main wing spar which is 1/4' BAltic Birch ply. Cut them out on my bandsaw and sanded them round on my spindle sander. |

Hi All. I'm going to try to build this thing. The plans were in the 1954 Air Trails Model Annual. I got them from the Outerzone site. It will be scaled at 3/4"-1ft. to match the Guillows kits. |
