Quote HistoryOriginally Posted By guns762: Well, dang..... The caliper come out and my fear was real. We are way to thin in the fuselage. We should be 18". We are not. We are about 6" too thin. This is going to be a huge problem and probably require us to rework the entire fuselage.  The frames are all just wrong. The CAD interpretation was so far off, it's just getting things worse, and as we work towards the engines and wings, it just makes things worse. It is probably easier to just start over with most of it. What a Monday.  |

Update 9/14
Measuring out and labeling each frame. Students labeled each frame with correct height and width.  All main fuselage frames pulled, and now we start to create new ones.  This is frame #1 to remake. We are altering the shape as we go for each individual frame. Too much of the original has going to be in the way of the intakes and would have had to be removed.

Update 9/15
Students spent time laying out the new frames yesterday. Once at a time, we adjusted them, enlarged them, and detailed contours.  We found a couple around the back of the cockpit needed moved just a little bit. We still have the tail frames to remake.  Even with strategy, our tiles needed a bit or rework in some places.  It's homecoming week....thus the weird outfits. Mural jungle is taking shape.   |

Grass doesn't make a perfect right angle around a concrete runway, it'll sort of mold a fuzzy corner at the top edge even if the roots are stopped on a square point, some grass should be obscuring the tarmac a little bit, not so much as to make another corner, but just enough grass tips to blur the line between grass and runway especially in that corner for an inch or two. Is that top picture the flattest piece of plywood you can get for $25? The edge looks like the profile of a water slide.

Update 9/16
More work on the mural......  Almost done on the tiling on the hangar. They are discussing paint on the outside right now and some detail trim. We should be ready for lights soon too.  Our F-22 1/48 scale model is getting used pretty much all the time now with the caliper. We stopped work on it so we could continue to take measurements without breaking details.  Last main frame laid out yesterday. You can see the outside box dimension they started with, then using the previous version, along with new frames further up the fuselage, create the new shape, paying close attention to changes that need to happen. We are leaving the tail fins short, as I'm not convinced we have the right angle yet. They were not the correct distance apart at the bases, in the original CAD drawing. We are second guessing all things from that drawing now. Caliper and 1/48 scale model are the go to. The wings are getting completely reworked also.    Tshirt artist has a few designs she put up on the board. The crossed rollers don't show up real well, but they are there in a few designs.    |

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.

Motor in ceiling can be 110V and then pulleys to get it on either end, so eash side balances the other end out so the effort needed is next to nil. Just need a brake on the motor to stop on a dime, or a big stepper which has great holding torque until the moment stops then it'd stay balanced, need 2x longer cable, sort of like how a garage door opener moves the door along the track with one motor pushing and pulling in the middle. |

If on a single cable, it can bank AND yaw. Motors can be in the plane - 1 motor per direction, line runs from the ceiling, to the plane, through the motor, back up to the ceiling.

Update 9/17
Frantic Friday Edition- It's Homecoming tonight, so it will be a bit more crazy than normal today. One of my students just drove through the parking lot with a very worn out Lincoln limo. He said he bought it for $800. There is also a military flatbed out in the parking lot.  Would make a good stage for a parking lot party.My model expert came back from Covid Camp yesterday. Work on Maverick and Goose's F-14 proceeds  Caulking and trim on our hangar finished up yesterday.  My limo owner needs to get back in the hangar and finish the painting so we can add the lights. Exterior should get more paint today.  Our F-22 looks much more correct now. A few more frames and some work on the tail, and we will be back to ribbing. We are probably 1.5weeks set back from where we were. Not great...not terrible.

You just have to figure out how to control them. I'm thinking you know how. One of our high school robots used a CIM motor and a gearbox with about a 185:1 reduction. Enough torque to lift a 135 or so lb robot off the ground. Also enough torque to twist a half inch diameter shaft 90 degrees. Getting that gearbox apart after that was fun. |

We are still aligning our rear frames to get the wing roots the same on both sides. Looks like we will have a little more work to do on that area this morning.

Wow!!!! Couple of awesome surprises today. This showed up in the mail. I don't see any mention of who sent it, so THANK YOU!!!! We are already using it.  We are making frame #6 this morning, the end of the weapons bay, and it will be immensely helpful with producing a similar curve to transition between #5 & #7.  @DRSALEE Thank you Sir! Amazing generosity.  More interior paint on our hangar.   The BF-109 will be crashed on this terrace.  We are close to having the wing root straight. We needed a little adjustment of the frames #8 . We loosened the screws and shifted them slightly using quick clamps, then reattached them.  We had a plan for the weapons bay, but that changed a little this morning. We are going to have the 2x2 go all the way along the bay now, instead of being segmented.  Frame #6 getting cut out  |

Why no 2.5D router matching the sides, or was the CAD so messed up you're doing it over manually? Now that I see the pin gauge (or whatever it's called "Single raster 3D manual scanner"), I don't know how any project looked right without it. -ETA: Contour gauge is a name. Thanks, Doc! We can torture the kids so much easier now. |

Update 9/22
With every successful fix, we find other problems with the original CAD drawing.  With the 1/48 scale model, we are seeing problems with the nose section that need addressed before we continue. It's too short, just like the fuselage. We think we have a plan and have started with parts to correct it.  Much time was spent yesterday working to get the weapons' bay frame to work.   The wing roots look much better now.

Guns, are you sure the 1/48 scale model is accurate? I haven't checked for the one you're using, but I've seen reviews on aircraft models in the past where dimensions have been off and shapes have been wrong.

It's way more accurate than the CAD drawing. It at least looks like a Raptor. I'm sure there are a few places where some things can't accurately be scaled, but it looks pretty good. If we can make it look like the 1/48 scale model, we will be doing better than the Iranians.

Update 9/22.2
Our "fixed" nose section of the fuselage.   Bottom weapon's bay is screwed in. We are now working on laying our the side bays. We will have to cut part of one of our frames away to make way for the internal bay area.  The center section of this frame will have to be removed.

Not a high bar.

Quote HistoryOriginally Posted By guns762: The center section of this frame will have to be removed. https://i.imgur.com/A6YYgM8.jpg So you'll be removing a few foot section of the "Spine" 2 x 6 (or 8+"?)? Will top and edges be affixed with plywood plate frame/body on the top (photo bottom) & side for a "Moment Joint" (set perpendicular to each other and stops movement/twists in any axis) which will hold it square and level? Maybe attach something rigid plate spanning 2 frames out from removal plan area then break the spine if that goes crooked it would be.. interesting. Sort of like the diagonal beams holding things square and plumb in houses, and 1' plywood triangles across corners in DIY IKEA sorts of furniture to stop the wiggles, but only more beefy / permanent and way more effective. |
