I end up doing a lot of this kind of stuff at work. Part of the fun is figuring out what mechanism will address the problem, and then building it.

I was more concerned about mounting the 3 mm pivot blocks closer to the top of the doors and having the pb wire droop into the engine path. Still have ability to change if needed. Jim Not only the ability to change, but the willingness to do it when it's called for. George Fly Army Country: USA | Posts: 16596 BurleyJim Fireman Premium Member Posted - 01/11/2021 :  4:51:26 PM     Scott, thanks for checking it out. George, I'm on it! By moving the pivot point away from the hinges, it will be an easier push-pull for those servo wires. The overall 'throw' distance will multiply, but I thinkI've got enough movement to make that work. So, I've already exercised the option and came up with 'Franks Bracket'. The nubs will face the back of the door, and it will glue on to the existing bracket. If it flys, I'll clip off the original wings, and give it more width clearance entering the stalls. On the printer right now. Thanks Frank & George!

While the flexing of the servo pushwires was greatly reduced with Frank1, the doors wouldn't open wide enough to let the engine in. So, it was time to rethink and redraw a solution. The 3mm pivot cube just wouldn't allow enough movement. so Jimslot1 was created to work with Franksbracket1. Still not enough to get the doors open wide enough. So, Franksbracket2 was built with a wider stance, but it had to reach further down into the opening. Jimslot2 was drawn and printed. By offseting the far end throw point. It easily opens and closes the doorway with a lot less drag in both directions. The new setup will take some rework on the front doors again. Stampcollecting was boring!

After all it's one of those YA3DPs. Frank Country: USA | Posts: 6088 robert goslin Fireman Premium Member Posted - 01/16/2021 :  01:25:05 AM     Excellent work Jim. Nice to be able to have operating doors. Very ingenious. Regards Rob My current build. http://railroad-line.com/forum/topic.asp?TOPIC_ID=53468 Country: Australia | Posts: 2665 BurleyJim Fireman Premium Member Posted - 01/16/2021 :  10:13:29 AM     Frank, you're right as usual. Rob, Thanks, the open/close mechanism has become quite a hassle. I used 'Bondic' glue to attach the fittings to the doors, and it offers almost no adhesion. Very disappointed in wasting money on it. Plus of course more rework time. Thanks for following along.

It would be nice to have your ability. Keep up the good work!
