| edtherenderman | Scratch Built Bugatti 100P | Build | 12-Dec-21 19:54 |  | | Views : 225 | | Put a couple of solid weekends into the Bugatti. This weekend was spent sanding (more on that later) and working on the landing gear. This picture is the gear retracted with the lower covers closed. I 3D printed the covers, wheels and wheel trunnions. Hydraulics are done with copper tubing and paper wrapped and glued with CA. |

These are just press fitted at this point and still have some fitting to do, but the results look good. Spinners were done with my FDM printer using Polysmooth filament. The propellers were done with my SLA printer. |

| edtherenderman | Scratch Built Bugatti 100P | Build | 14-Nov-21 19:44 |  | | Views : 272 | | Taking a break for the holidays so thought I’d post the current state of the Bugatti. 3D printed exhaust fairing and cooling air outlets that are on the trailing edge of the wings. Glued and filled with spackling, then coated entire model with five coats of thinned EZ-DOPE. Finally, two coats of sanding primer. Next will be sanding the primer and filling anything that needs it. |

| edtherenderman | Scratch Built Bugatti 100P | Build | 05-Nov-21 22:04 |  | | Views : 341 | | Here are the pulleys with the belts, but pulled slightly out of the transmission housing. The lower drive pulley works the larger drive shaft which is the inside propeller. The upper pulley is the inside driveshaft for the outside propeller. Note the belt for the upper pulley is crossed. This creates the counter rotation. |
| edtherenderman | Scratch Built Bugatti 100P | Build | 05-Nov-21 22:01 |  | | Views : 293 | | I couldn’t let the counter-rotating transmission go! I realized that gears wouldn’t work, but what about belts! I re-designed the gears into pulleys and thought I would use rubber bands, but couldn’t find anything small enough. Then a friend at work told me he had some filament for his FDM 3D printer that was very flexible and stretchy. He let me borrow a spool and I printed out the belts. They worked okay, but didn’t grab well, so I also printed out the pulleys in the same material and it worked like a dream! |

| edtherenderman | Scratch Built Bugatti 100P | Build | 10-Oct-21 21:22 |  | | Views : 286 | | This week I build out the control surfaces as well as 3D printed the split flaps. Also made great progress infilling the fuse. Next big task is sanding and filling. Always fun with lots of dust everywhere! |
