| Rayl, thanks. This is a great idea and a nice job of explaining. As I said before, it beats doing it in the oven and burning fingers pulling on hot plastic. |

SO, here are the three sections of the canopy for the XF-92A. I need to trim them all to fit. One thing that I should have done was lay out the section lines right on the master to give me a guide for cutting them. I know that I have probably forgotten to put in some information, so if you have a question; feel free to ask. |

Done applying heat. BTW I have a paint stripper gun that I use; don;t know if a hairdryer has enough power to do this. This master is about 7 1/2" long as is just at the maximum that will work with a "Coke" bottle. I had already formed two other sections of this canopy, the windshield and the clam-shell portion of the canopy so I was interested in forming the back turtle-deck here which explains why the front of teh canopy is not fully formed. When appyling the heat, be aware that if the plastic starts to fog, it has shrunk as far as it is going to at that point. Also, you might find that there are some creases of folds that appear when forming: just judiciously apply a little more heat to that area and they will go away. |

This is a shot of how the bottle is shrinking when I'm about half-way through the process. I keep pushing teh form up as the plastic shrinks. The bar is a piece of 1/4' X 1" aluminum and it does deflect during the process. Start applying the heat BELOW the master to keep wrinkles from forming and to insure even shrinking around the master. |

Here the canopy master has been inserted into the bottle and the caulk gun used to put tension on the bottle prior to beginning to heat the plastic. |

THis is the top side of the rig. The piece od aluminam strap is to keep tension on the 2 liter bottle as the forming process progresses. I ussed a a couple 1/2" X 20 carriage bolts with wing nuts to allow for easy removal and installation. See how the (open-ended) bottle is clamped to the ply? |

I thought that I would share a method for forming canopies (or any other shape that you might want to mould) out of a 2 liter softdrink bottle. This is the apparatus that I duplicated from "ModelMaster 2001" over on the RC Groups forum. It is a el-cheapo caulk gun mounted to a piece of 3/4" ply. I shortend the caulk gun body by about 4 inches to make sure that I had enough stroke to keep the form tight to the plastic when heat is added. |

| AWESOME!!! |

Moby Dick on a stick! After much angst and hand-wringing, I'm going with the White color scheme that it last flew in. I just didn't want to get invovled with the natural metal or foil hassle. While the paint is curing, I'll start on the cockpit. Later. |

| John & David: Clicking on your names worked. Sometimes I feel so dumb. |

| Click on "your hangar" under the main menu, then on a name. That will bring up all builds for that name. |

Gathered up most of the scrap wood today. Looks like I've got enough material to start to make another fairly good-sized model. (Maybe a 1/16 F-82 or even a Bamboo Bomber. Hmm. |

In the groove today. Neil Young playing on the box and a little Chivas (might explain being mellow). Doing fiddly stuff like making all of the vent holes and scoops/dumps in the after-burner section and the tail bumper. So, the next thing will probably be to finish the landing gear, which for some reason, I just don't want to get invovled in. |

| https://www.youtube.com/watch?v=hnwZLk7s6PI Tall Man 55 is a film from 1960 about B-58s making a simulated bomb run against a RBS site. RBS is Radar Bomb Scoring and is what I did from 1964 to 1968 with a couple of trips to Viet Nam thrown in where the radar was used to direct real bomb drops. I saw F-102s in the early 60s while stationed in Spain. While I was stationed here from 74 to 79 our shop was next door to an alert hanger which housed two F-106s and it was a real pleasure when they came out to play. Nearly everything else was camouflaged at the time but they were shiny gray and quite impressive taking off, shaking the whole hanger! |

| Yep. Based on Dr. Lippisch's work in WWII Germany. The '9r was the predecessor 0f the '102, '106, B-58, Sea Dart, and the Pogo. It was marginally super-sonic and reportably had good handling characteristics. |

| predecessor of the dart series? |
