I test printed a model today that I created last week based on SimHQ posting I saw.
Here’s what the solid model looks like:
The lettering on the face of the grip relates to the control that hinges in the center of the grip – it controls propeller pitch. It roughly translates to “Coarse” and “Fine”.
Here’s how the print came out:
As you can see, the lettering didn’t turn out at all. This could be fixed in one of three ways. Increase the size of the lettering (not really practical), print with a smaller diameter nozzle – this was printed on a .5mm nozzle. A .35mm might be small enough. Last, you could print it flat and then mechanically engrave the lettering in post production.
My choice would be to do the lettering as a post-production step because the smaller nozzle diameter would dramatically increase the print time of the part. At 0.5mm it took roughly 2 hours to complete. With a 0.35mm nozzle, it would be closer to 5 to 7 hours.
The square pockets shown in the second photo are there to take a C&K 8221 tactile push-button switch. Here’s a photo I shamelessly lifted from Digikey’s website:
The rocking lever that goes on the face of the grip would hit the switches as it is rocked from top or bottom. I don’t know if I’ll finish the design, but it was a fun design lesson and an interesting print.
This project has been simmering on the back burner for a very long time now. I only recently got a chance to scrounge up a round-tuit in order to get this thing done.
With the advent of the Arduino hardware ecosystem has come a general bar-lowering for people doing all kinds of projects. This especially holds true for those of us building simulators of various stripes. You can find Arudino-based gadgets driving instruments and masquerading as all kinds of little cockpit gadgets these days.
One of the holes in this has been a genuinely easy to use flight control interface based on the Arduino. Well with the introduction of the MMJoy2 firmware as written by “mega_mozg”, this hole has been filled.
As I mentioned before, the instrument panel on the Bf-109K4 (and some G models) consists of three parts. An upper “casting”, a main panel and a blind flying panel.
Since I had the day off today, I took a little time to get some work done before it got too hot in the shop to work.
The original panel mounts that I created aren’t going to work with the current cockpit design, so some months ago, I fabricated some new panel mounting brackets on my 3D printer.
The green part is the original bracket I printed last year when I first started poking at this project. The small white part is a drill template, which is also 3D printed.
