| edtherenderman | Scratch Built Bugatti 100P | Build | 20-Dec-20 11:32 |  | | Views : 391 | | I’m designing a transmission that will duplicate the counter rotating props and looks like the one used in the real world duplicate. When one prop spins, the other spins in the opposite direction, and the drive shaft that go through the cockpit will spin also. I plan to print this on my 3D DLP printer. |
| edtherenderman | Scratch Built Bugatti 100P | Build | 20-Dec-20 10:24 |  | | Views : 459 | | Starting new project: Bugatti 100P. I found out about the aircraft when I ran across it in the Old Machine Press (https://oldmachinepress.com/2012/11/01/bugatti-model-100p-racer/) several years ago and thought that it is one of the cleanest aircraft designs I’d ever seen. This aircraft was never flown in period, however a replica was built in in the 2000’s. Unfortunately, the pilot and builder, Scotty Wilson, was killed when the plane crashed on a test flight in August 2016. I have not been able to find any balsa model plans for this aircraft so I’m going to create my own use a 3D model created in Blender.org. This is a render of the model. |

I can see quite a few stringers here that you can’t really see in the photo. Definitely needed to send more time sanding the bottom. Will require quite a bit more fill and sanding. All part of the fun! |
| edtherenderman | Scratch Built McDonnell XP-67 | Build | 13-Dec-20 20:16 |  | | Views : 488 | | Top of aircraft. I completed sanding and filling, covering with tissue and first few coats of primer. Need to so some minor filling and sanding. |

| edtherenderman | Scratch Built McDonnell XP-67 | Build | 13-Dec-20 20:11 |  | | Views : 295 | | Weathers getting cold and wet in the PacNW so started working on the XP-67 again. I modeled the cockpit using Blender and printed out on my 3D printer. Photo references are really hard to find. I was able to find three photos on the internet. One is of the left side of the cockpit. One is looking forward ¾ view from right to left so that you can see some of the left side and the dash board. The other is from to top showing the dashboard, floor boards, rudder pedals and a little of the sides. I could not find photos of the right side or the seat. So I use contemporary aircraft (P-38 and P-47) as references. |

| edtherenderman | Scratch Built McDonnell XP-67 | Build | 26-Oct-20 10:58 |  | | Views : 357 | | Here is the fuse with wing tips and tail feathers installed. Still have a little more filling/sanding to do, but pretty close to applying tissue. |
| edtherenderman | Scratch Built McDonnell XP-67 | Build | 26-Oct-20 10:56 |  | | Views : 265 | | Also modeled and printed propellers and spinners. The XP-67 went through a lot of versions on the two prototypes built. They had a lot of problems with engine cooling and eventually had to use “Cuffed” propellers to get more airflow into the wing leading edge intakes. I decided to model one of the later versions that used the cuffs. |
| edtherenderman | Scratch Built McDonnell XP-67 | Build | 26-Oct-20 10:54 |  | | Views : 309 | | Update on work done over the last couple of weeks. Modeled and printed the canopy framework. This is VERY fragile, but should look really good once on the aircraft. |
| edtherenderman | Scratch Built McDonnell XP-67 | Build | 09-Oct-20 08:50 |  | | Views : 425 | | I also 3D modeled and printed the canopy. This is the first time I’ve tried printing with clear resins in my DLP printer and I ended up doing three prints before I figured out the configuration and parameters needed to get a successful print. As it was, it took 13.5 hours to print and it isn’t transparent coming out of the printer. This image is of the canopy after spending about two hours wet sanding with 600 to 1500 grit paper, then moving to rubbing and polishing compound, finishing with composite headlight lens cleaner (Mother’s brand). I still have to print the frames that will sit on top of the clear glazing. That’s next. |
| edtherenderman | Scratch Built McDonnell XP-67 | Build | 09-Oct-20 08:44 |  | | Views : 314 | | Before I left for Alaska for a Fly Fishing trip for Coho a couple of weeks agao (brought back 25lbs of fish – very fun trip!) I started doing some more work on the XP-67. I sheeted the outer wings and tail feathers, and build the Ailerons, Rudder and Elevators using 1/32 sheet balsa with ribs added and sanded. When I got back, I covered the movable surfaces with tissue. Still need final trim and fill coats of EZE-DOPE. |
