Measure once, cut 87 times?

Well, isn't this a fine kettle of fish.

Life is about choices.
If you make a mistake once, it's a mistake. You make the same mistake again, that's a choice. |

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. |

I haven't kept up with the last few pages - are you using lexan or acrylic for the canopy? |

Lexan. 1/16th thickness Any particular reason for the choice? While Lexan is stronger and can be formed easily, its glass transition temperature is higher than acrylic by about 100deg (~200F vs. ~300F), making handling a little trickier. |

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

View Quote 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. |

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. |

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. |

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.

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. View Quote Ooooooo!

("On"! ) View Quote I'm not real confident we can make that work. We will see. 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. Failed To Load Product Data 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. |
