Update 10/12
Dear GD, The day was going so well...... The students were excited after watching the YouTube video.   The internal anchor points for the wings went on easily.  More printed pieces for our bay doors actuator.  There was progress on our tower, even with half the team diverted to canopy bodywork.  Mural work had been slow, but it is getting done.  Things were going so well, we moved the F-22 out into the breakout area........  It was exciting for students to see this appear, and many of those working on it commented on how much bigger it suddenly looked.  I have a student who loves doing body work on cars working on our canopy form at the moment. He painted it plank then sanded down areas to find high and low spots. Hea pretty dang good at this.   Then came the late afternoon.....  We are still working on the tail and placement of the flaps. While doing this we began to notice not enough space. Ater much measuring andremembering, I sing the end of the wing as an anchor point, our fuselage around the engine exhausts, is about 7inches too short, and somehow, over all we are about 5" too long.  We are now tearing them down and adding spacing and hoping we get closer to the gentle slopes that we were missing on those pieces.

Quote HistoryOriginally Posted By backbencher: Measure once, cut 87 times? We figured out how it happened. When the students were measuring , we didn't have the wings on, and they were trying to use an anchor point on the model that didn't exist on our frame yet. They also made a slight error assuming the wing end and the tip of the tail wing touched.....they are 3.4" apart. That and the above anchor point error induced the 7in problem. Dont ask me why we are also too long over all....that one I have no idea.

Don't forget to leave extra material around the perimeter of the canopy for attach fasteners.

We won't get the lexan till tomorrow, if shipping stays on track. We will probably make our first attempt next week. Today will be rebuild the Raptor's ass end, and develop the cargo bay frame work. Of course, more bondo and sanding on the canopy "buck", as well as our halo guide. |

It's not as brittle when cutting. We've had bad luck with acrylic cracking. That's about the only reason. |

Quote HistoryOriginally Posted By guns762: It's not as brittle when cutting. We've had bad luck with acrylic cracking. That's about the only reason. Yeah, it is prone to do that when it's thin - if the woodshop has a band saw with a bimetal blade, that works pretty well. If you're using a jigsaw, a grit blade with the acrylic sandwiched between a couple pieces of luan works as well. The acrylic might be easier to form, although it does have a bad habit of forming bubbles if it gets left in the oven too long. It's also cheaper. |

Update 10/18
We had Friday off, and I got lazy, so I did not update over the weekend. My old phone seems to have died this morning, so photos may not happen for a few days.  Luckily, I uploaded last weeks photos Friday.It was an interesting afternoon, Thursday, specifically, the last hour.  Before I get to all that, some cool update photos on the ostrich egg project Display box  Dragon embryo showing up with the light  The canopy is getting extremely smooth and even.  This was their map for today. the circled areas are where they want to concentrate. We will probably put off our canopy glass attempt till later in the week, because of the issue that is outlined below.  Contour levels getting installed on our flight control tower   We did get the 7" inches corrected on the last section of the fuselage. We still didn't know where the extra 9" overall was though........  The contours look so much better now.   The the day went all pooooy. The students working on the weapons bay doors went to install them, and were not happy about where they were suppsed to install them. The math did not put them where our weapons bay was.  After some math and remeasuring every section of the plane....we found our +9" Problem. The section behind the cockpit, and before the wing edge is 9" too long. This is not something we want to fix, but we have to. We did something similar with the VH-60. We will have to cut out the ribbing, and remove all the screws on the frames aft of the cockpit. Once that is done, we will slide the entire fuselage up to meet the cockpit section. The weapons bay will have to have a little rework also. We think we can do this today. It seems daunting, but since we've done it before, I know it won't be impossible. This is the look of, "I can't believe we are doing this".  The section that is too long   |

No pictures.... phone is kaput.
We got the initial cuts done, and screws backed out of all of the frames. Its funny how if there is one screw still in one of the frames, the whole thing will not move. Even with all of the screws out, we needed ratchet straps to slowly squeeze the fuselage up to meet the cockpit section. Reassembly will begin with the frames, then the secondary connecting 1x2s and 2x2s. We are going to have to take a hard look at the whole bottom around the weapons bays. There may be more rework there. Theoretically, everything should fit better now.....theoretically.

Quote HistoryOriginally Posted By backbencher: It's like a broken engagement - better you found out now than later. Glad you found the issue, OP. We aren't out of the woods yet. We have the fuselage upside down and are trying to map out where the damn weapons bay goes. The math is not adding up. It's frustrating. I do have a suspicion on how our measurements got so far off on the one section. The caliper we have is digital. It measures in both mm and inches. It takes only an accidental button bump to switch from one to the other.  My Samsung showed signs it might come back from the dead, but it seems to now just be quivering in it's last death throws. It keeps trying to reboot, but never gets to the Verizon app portion, then starts over. New phone shopping tonight after class.

Quote HistoryOriginally Posted By brass: https://i.imgur.com/ElEzL9D.jpg To get a "straight" edge at the top of the grass to the sky, cut frisk or mask to match the curve, or just make a big french curve that would have all the radius needed. Then hold it about 1-2" away from the wall and follow your landscape while spraying 8" in front of the mask to get a very uniform nice and fuzzy fade. Might take two people (one holding curve another spraying, though one can do it in small bits at a time, just keep distances between wall and mask and mask and gun constant. or some stand offs and a bit of tape but once that prep is done the actual painting goes nearly instant. The closer the gun is to the frisk, the softer the line, the closer the frisk is to the work, the harder the line, with the extreme being with masking tape stuck to the very edge giving a literal wedge of color change. I have seen people use the 3" 3M Blue tape and fold in thirds twice once with sticky side out the other in so that you have a tab resting out from the wall like a ledge with the thinnest part taped lower, then work along the mask with proper gun placement. That's one of the methods that are used when blending colors with airbrush on a vehicle when a huge line of fade needs to be kept straight and uniform. Cut tape lengths (long are easier to get perfectly straight than short, also harder to origami, fold over 1/3 on itself so there is 2/3" of sticky left, put that along edge then flex ledge over line to keep and spray so the line is in the "shadow" of that tape edge. Ho-lee chit Brass, what DON’T you know about? Wish you lived in my neighborhood so I could pop in with the random “hey, what do you know about....?” |

Quote HistoryOriginally Posted By guns762: As a couple of my team leaders tackle the new wing structures, they are suggesting we have 4 cables to hold the F22. Two to support the weight, and one on each wing tip to make the Raptor change positions during the day......... I'm not sure we can do this, but dang!  I told them, my answer is not a "no". We will pursue it a bit and see what we can do. Motor or two per wing able to spool up and down doesn't seem that difficult. If we have the balance right we should be able to do it with a single motor spooling up one wing, then allowing gravity to bring it back down later when it unspools.Ooooooo! When you’ve a game against other High Schools you move to “Competition Position” or if you’re school isn’t too PC, “Combat”

Update 10/19
Here is the section we are now reworking a bit to get the weapon's bays into the right area.  It required removing one frame from the front to allow the bay to be a bit further forward. We also removed a frame from the back of the bay area to allow for it to be the correct size. Removing the rear frame is making us adjust a few contours in the middle of the fuselage a bit. It looks a bit rough in a few spaces, but most of this will buff right out. Students will hopefully define the weapons bays with 2x2s and 1x2s later today. This should strengthen up our bird just a bit and get us back to details like the doors and actuators.  Its a good thing we didn't cut off the 9" of the main beam, because we are exactly that short on the center of the fuselage. We believe we have the basic dimensions all correct....for now. We are making another frame to add to the end of the main beam. This will be where we attach the exhaust nozzles. Flight Control Tower is going well. Students are starting to add the outside contours.  The jungle is looking good. We have a bit more work to do on value contrast in certain areas. I want to see more dark grass and spaces between the larger plants to make them stand out.  The 3D airfield tiers are doing well. We are making sandbags, and work on the BF-109 is going well. We should be staining the bottoms of the landscapes soon, and adding more details.

Update 10/20
The canopy is still on hold for a bit. We have the plane still inverted to finish up on the weapons bays, so it really isn't something we can access easily. I'm hoping we can get back to motor mounts and running power before the end of the week. The weapon's bay framing is going well. I think we will have a lot more structural integrity across the fuselage with the way we are doing it.  Students will work on framing both floors for side and bottom bays today. There is some tricky measurements and cutting to get this done.  The last frame before the engine exhausts just needs the inside cut out.   This will be a mounting plate between the wing and fuselage to provide a little more stability, especially if we are using the wing to change the orientation of the plane through out the day when it's displayed.   This was posted in another thread. Pretty cool video, and I've only watched a few minutes. I shared it with a few students already this morning, but finding a whole hour may be difficult to do on a class level. Special Lecture: F-22 Flight Controls  Special Lecture: F-22 Flight Controls |

Update 10/22
I shared the MIT Video with classes, and a link for those that wanted to watch it in full, or again. Several of my students have commented on how excellent the lecture was. It's been fun talking planes with them.  My wing/elevator/rudder engineer/designer wants to put "44000lbs" of hydraulics in ours. He's working on his pilots license and really got into the lecture. We've spent the last couple days working on the weapons bay floors and internal frames. This has been a lot of try this, try that, type of engineering. We wanted to add a bit of stabilizing to our overall air frame, but also not add much weight. We also had to adjust the outside shape of the bays just a bit, and also the fuselage in a couple areas where we were not symmetrical. It was just little amounts here and there, but it made big differences to everything coming together correctly and to scale. We still have to trim down the 2x2s that form the bottom outside dimensions of the bay. Those we will do sometime today.    Both side and bottom weapons bay floors are getting created with this framing.  We are still having quite a bit of fun, and this is a great crew to work with.   For @extractr Beginning work on your warthog. Thanks again for providing this opportunity. I don't think we've ever had a chance to work with an African species before. It will be a challenge. I'm looking at my warthog at home for some indications of how they do the warts professionally.  |

Update 10/25
Friday we finished framing up the internal weapons bays.    Kind of hard to see the internal framing from the top, but we flipped the bird at the end of the day.  We trimmed up the outside edge of our 2x2 on the weapons bays to better fit our contour.  Our canopy press needs a bit of trimming and final fitting.  Our control tower has more outside structure on it now.

We are currently discussing the "mach cones" coming out of the thrust vectoring nozzles. Students are framing out the nozzle area and we want to make sure we have enough stability there to attach the cones if that is what we do. Our idea is to form clear tubes of lexan/acrylic. Those will be attached to the nozzles. Inside the tubes we would spiral out bundles of fiberoptic lights. We found with the unicorns that where we hot glue the fibers, creates a light point. The hot glue to attach the bundles round the inside of the tubes should allow us to create the mach cones we need. That is the theory. We might be able to spray a thin coat of paint inside the tubes to add a bit more color in the areas we need.Not cheap, but would do both engines. Students are a bit skeptical of the overall affect of this. The thought is the tubes just won't look good. The nozzles will be pointing up a bit, like our tractor lights, so much of the inside will never be seen unless we add mirrors again. I guess we can scrap the tubes if they don't look good. Maybe wait to order the light kit until we have two good tubes turned out? Thoughts would be appreciated.

The hot glue to attach the bundles round the inside of the tubes should allow us to create the mach cones we need. That is the theory. We might be able to spray a thin coat of paint inside the tubes to add a bit more color in the areas we need.Not cheap, but would do both engines. www.amazon.com/dp/B08QMZD2K2 Students are a bit skeptical of the overall affect of this. The thought is the tubes just won't look good. The nozzles will be pointing up a bit, like our tractor lights, so much of the inside will never be seen unless we add mirrors again. I guess we can scrap the tubes if they don't look good. Maybe wait to order the light kit until we have two good tubes turned out? Thoughts would be appreciated. |

You could just do it authentic, but the noise might bother the classrooms.

Sort of a scale model of your scale model |

There's got to be some members here with ties to a Raptor Wing or two that could hook you up with some patches and swag.

We are getting closer to a design of our own. There is still a bit of work and adjustments I'd like to see, but my artist is doing great. Kids like this design.

Update 10/27
It seems to be crawling, this finishing up the framework, but I think we are almost there. This is the side weapons bay. We need some hinges, somehow one was missplaced, but the doors will get a little adjustment in size today and then we can start working to get them attached.  Our wiring is being reworked to account for movement in the internal frames, and where we are going to need power, motors, lights, ardunios.... The vectoring nozzles will start to get sculpted today. We attached a 2x2 to the 2x6 for an internal structure. This should be more than strong enough to attach our clear tubes with lights.   My pilot has the elevator frames all designed, sculpted, and ready to assemble. He has moved on to the tail rudders.   We have our press all detailed out to fit over our canopy. We should be ready to go ahead and attempt our mold. We even cut out our lexan yesterday afternoon. We may have to clear a kiln and finish the supports to hold the lexan in the kiln today before any attempt is made. I'm less than confident about this actually succeeding, but it's worth the shot and experiment. I just hope the students don't get to flustered if it doesn't work.    The Science teacher put up her plants yesterday. She said they will come down again today for some adjustments. We talked about painting part of the towers to march our mural. That may come at a later point. Now, for that F-4 and it's napalm run.........  |

Good info. Making notes for the student. Thanks. If we put this on the tail of our F-14, would the "VF-307" be appropriate? |
