First Wing Spar Done - Building the Raptor Prototype 

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.

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 Pete! Great work as always.

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.

Happy birthday sir, have a great day off, and a wonderful birthday! Thank you for all the videos.

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.

Looking good! Why not counter bore the window bolt holes so bolt heads become flush?

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??

Where is tuesdays video?

Cool room is

Why not a 150lb strut on each side?
