First Wing Spar Done - Building the Raptor Prototype

- The first wing spar is now complete so that just leaves the other one to do next week. There are a couple of close outs that will still be added but we are so close now to having no more parts to create for the wings and fore plane. It will be very rewarding to be able to start bonding parts of the wings together in the fixtures that we created awhile back.

Happy birthday for next week! I'm so pleased to have found your project right at the beginning, it's been a fascinating journey. I wish you every success.
Happy birthday Pete! Great work as always.
I really like the idea of bolting those windows in to the frame. Awesome
I think this single engine will be a revolutionary project, I hope to see it done soon. I follow every new video. Great quality.
Happy birthday sir, have a great day off, and a wonderful birthday! Thank you for all the videos.
This is a very nice Job. I follow every update. I am following curiously to see this project come to reality, and be part of the first customers. Happy Birth day.
To drill acrylic glass, a negative cuting edge is needed. Much the same way as it is for brass or wood (and with these specialy purpose drils you picked). When using a brass drill bit it's useful to have the other side tied to a flat pice of wood to avoide a broken out rim. Using wood drills avoide this anyway. Almost more important then selecting the right drill bit is the speed and timing. Let it run slow. Best is produceing acontinous, maybe broken flake. If the flakes turn into crumbs the speed is too high, if they start to look glazed, temperature is buildign up to high. It takes some patience. Usually only do like 5mm (1/5th of an inch) at once, then give it a few seconds to cool off. A clean and shiney surface with sharp edges will be the reward.
Enjoy your birthday. You deserve it. Very proud.
good progress have a great birthday !!!
Hello
I have been watching your build all the way from Sweden. I may have some time savings for you.
For large layups you can get carbon fiber prepreg with a epoxy that is made for oven curing only.
Also kemical release media is alot faster to use than to wax and PVA spray the molds.
Black oxide will rust pretty quickly. the coating will be scratched when the hardware is installed. When moisture hits it, it will corrode.
Happy birthday, good work, happy to see the wing spar come out well.
You should consider doing a little re-cap of things that will and won't be in the production aircraft at this time.
I understand that you are focused on getting the prototype flight worthy but I think many people are not aware that you plan on changing the door design entirely.
And that many of the "belt and suspenders" design changes will be stream lined in the production design process.
The people who are not aware would likely miss the video with the update any way so it's just a waste of time for me. Sorry.
Raptor Aircraft , fair enough, as usual. Have a great day off !!!
Looking good! Why not counter bore the window bolt holes so bolt heads become flush?
I am counter boring the holes to match the fillet that is on the back side of the hardware.
Cool room is
Cool room is a great idea..... I'd recommend putting the epoxy and hardener is an environment to cool it to the lowest permissible temp, I've found that to add more time than a cool room. I've actually lost a piece (or two) in an airconditioned room and 90 degree (f) epoxy. Just some suggestions from past experience I love your project and only wish you the best cheers!!
A part of me wonders, given all the bricolage you've had to do to make the doors 'work', if it wouldn't have been easier (maybe even now safer?) to get the door moulds out of the warehouse and just make 2 new doors wherein all the mods can be freshly incorporated, including embedding the aluminium reinforcements directly into the door frames??
I agree ............ the time spent on the doors thus far has simply been the learning required to design a much better one......zero shame in that......I would ditch the doors and remake them entirely.......
He has an entirely different dual door design for the production aircraft. These are for the prototype only. I do believe that the window mounting will be re-designed as well.
Where is tuesdays video?
Why not a 150lb strut on each side?
For the simple reason that is not enough force to hold the door up based on the location on the strut mounts. Because Physics!
Lol... Physics... Physics is for the birds! Well I guess I was thinking more about distributing the load on each side rather than the torsional stress you are trying to overcome now. So then let me ask why not 2x200lb struts or whatever it would take to make a symmetrical load?
Oh and thanks for the Saturday upload. Enjoy your time off!
