| He appears to know how to cut gear teeth to mesh properly - it did not BLOW UP on full drill speed!! - remember, "The Fundamental Law of Gearing", states, that the angular velocity ratio, between the gears of a gear set, must remain constant throughout the mesh. 8-) |

Ian Jimmerson explains how a Radial Engine uses a Cam Ring Plate with "lobes" on it, to move the "lifter rollers" that are attached to the bottoms of the push rods, which then go up and down, to open and close the intake and exhaust valves at the tops of each cylinder (as opposed to a Car engine which uses a Camshaft with lobes) http://fireaviation.com/2016/01/23/carpenter-builds-wood-model-of-9-cylinder-radial-engine/ Part 1 - 10 min - Part 2 -9 min video |

HOW A RADIAL ENGINE WORKS Carpenter Ian Jimmerson has built a huge working model of a 9 cylinder Radial Engine, out of wood with clear plastic tubes on the cylinders, so you can see them go up and down, and carefully explains how all of the parts work together, and he turn the crankshaft slowly by hand so you can see everything moving. This guy should be ( maybe he already is) a teacher. Here is the video link http://fireaviation.com/2016/01/23/carpenter-builds-wood-model-of-9-cylinder-radial-engine/ Part 1 - 10 min video and Part 2 - 9 min video. Now I know how the Radial Engine works!! |

| Richard, I'm a great fan of British aircraft and their design. You have an email? |

| Hi rayl. Yep, you are right. They are weather resistant fiberglass replicas that were put up there in 2005 when they took down the Lancaster Bomber which was up there for four decades and is now being restored at the Historic Hangar at Windsor Airport. There is a concrete curb outline on the ground under the spit and hurri which really shows the size comparison! |

| Richard, Am I correct in thinking that the Hurri and the Spit are Fiberglass replicas??? |

COWLING: This kit comes with a beautiful 0.015" thick sturdy Vac-formed Plastic Cowling with well marked cutouts of the engine air cooling holes. I securely thumbtacked the back flashing of the cowling to my workboard, put on a fresh new #11 Exacto blade, and carefully and slowly cut out all the holes with no major mistakes, thank goodness. I then finished them all of with some more thin slices with the blade, and sandpaper sticks and metal files as best I could, and sprayed it inside and out with Metallic Silver which actually turned out to match the fuselage Metallic Silver tissue. |

The mirror reflection of the engine adds to the glimmer and shinnyness of the engine compartment behind the cowl. |

I brought the engine to life by gluing that chrome "backplate" , cut to the shape of the front of the former sitting directly behind the engine, with the chrome side facing forward towards the engine |

Please pardon me for my over-indulgence overkill of pictures in my build threads - it's that darned "new camera syndrome" exuberance!! Please indulge me a few more .... This kit has a neat little detailed engine of built-up balsa and laser cut card stock for the cylinders. To enhance the blue-gray color of the engine, I made a chrome color "backplate" out of adhesive-backed (peel 'n stick) Trim Sheets from Top Flite, which are made of Monokote, which come in many different designs and colors, including 5 checkerboard schemes and neon colors as well. |

These props are not really that hard to carve. Just give it a practise try on a soft single piece block of balsa. This was my 7th out of 8 props - 2 of which were practise. |
| LASTWOODSMAN, Image # 37469 | 09 Dec 16 11:39 |
It came out as 3 distinct wood grain colors repeating in the prop. |
| LASTWOODSMAN, Image # 37468 | 09 Dec 16 11:38 |
I then hand carved and sanded the Axial prop, stained the whole prop with "Golden Oak" color, and then clear coated with Krylon Clear Gloss. |

I let the 13 painted rectangle plank sheets dry completely, then I white glued them all stacked together and clamped them up in one big prop carving block of 13 layers and let it dry for one week. |
| LASTWOODSMAN, Image # 37466 | 09 Dec 16 11:31 |
Each balsa layer sheet plank was brush painted in acrylic paint - 1st layer "Bronze" color, 2nd layer "Burnt Umber" color, and 3rd layer "Brown" color, and repeating Bronze, Burnt Umber, Brown, Bronze, etc. |
