Random Pics Of My GA Build
I will have the updates of my build in this thread.
The faceplate is base on 172N that I yanked out from our local boneyard here in Cali. Painting this thing actually takes longer than building the whole flap unit =[.

Re: Random Pics Of My GA Build
Clear acrylic is still implemented in this design and it will be mounted inside the housing.

Hi Louie,
Looking good. What equipment are you using to make your pieces?

Thanks Jake! I use waterjet, finger break and laser cutter.

Re: Random Pics Of My GA Build
I had to fabricate my own special tool to give a 90 deg fold without warping the mounting ears. I know it's missing some screws :D but this design is done!

Re: Random Pics Of My GA Build
My CAD prog is acting up for some odd reason I'm unable to install the extension spring on this design. The picture is self-explanatory where the spring is suppose to be constraint.

Re: Random Pics Of My GA Build
Looking Great!!!
I managed to snag the actual flap lever and knob out of a 172 so I'll be adapting the two gears you sent me to that. My original design used a slide pot but the gears you sent me will allow me to use a rotary pot and that will work far better. Other than the original slide pot the control and position indicator that I am working on looks very similar.

The Garmin project is shaping up nicely as well! Looking forward to more progress and pics.

Re: Random Pics Of My GA Build
Whoa! very nice. How did you make the slider work in a horizontal position?
Folding the sheet metal in a U-shape is a bit of a challenge specially with very little space to work with. I had to make my own V-block and press break die so it doesn't harm the mounting ears. Thank god for FloJet, sim-building and tool making got easier.

I use Google Sketch-up for my drawings so some things are a pain to draw. But free is good so Sketch-up it is.
Not shown in the drawing, for that reason is a linkage between the top of the flap control arm and the slide pot. Because the pivot point sits so far below that it moves the slide reasonable well. However, I think the gears you sent me may work much better so I'll be trying that with a rotary pot.
As for the bends on the bracket, my efforts so far have all been done in a temporary bench jig. I have not yet figured that out how to get those two very close bends at the back of the bracket. I don't have ready access to a sheet metal brake so my sheet metal work is done in a rather primitive way using a combination of a bench vice, anvil, wood blocks, and a hammer. :shock: I get fairly good results, but I'm too much of a perfectionist so it's a real pain. I was contemplating moving to a two piece bracket if I could not manage the bends any other way.

Re: Random Pics Of My GA Build
I have tried 2 piece brackets but it tends to sway the flap lever bracket as I shift the handle. I'm pretty sure there's a solution to that problem. One solid frame is far more stable like what you said it's a pain making things perfect =).
Update: I found a solution for the 2 piece brackets

Louie: Thank you very much for sharing these photos. I would like to ask how did the knobs and buttons of Garmin 430.

I had to mold them from the actual knobs and buttons. They are primed, painted and laser etched.

Oh man I need a break. I'm gonna go to Frisco tonite and hit up a lounge. Enjoy the rest of the weekend everyone!

Hey Pal,
Congrats on the excellent work, you indeed look like you need a well deserved drink, go and take a flight somewhere and enjoy the fresh air!
Congrats on your progress, excellent work!
Thanks for sharing.

Re: Random Pics Of My GA Build
Louie,
My flap control and position indicator is no where near as polished as yours, but I figure not bad for doing the sheet metal work with a hacksaw and the bends in a bench vise.
I got it assembled this evening for a test fit. I need to make a few of adjustments and add a return spring but it looks like it works as planned. I also checked it in my fuselage and it's a perfect fit. If you look close you'll see that the two gears and the face plate you sent me are in there.

Getting it rigid enough with a two piece bracket turned out to be no problem. I used 4 10-32 x 3/4 rod couplings to join the to plates and it is as rigid as a one piece bracket, maybe even more so. I'm hoping to test it on the pc tomorrow. My only concern is the gear ratio. The movement of the pot shaft is fairly small.

Re: Random Pics Of My GA Build
You seriously got the touch Tom! I like it again :D
I tested the gears and they are enough to make it happen. However if it doesn't work for you I have different gear sets in stock or I can custom cut (cdw, bitmap or dwg file is fine)them for you.

Re: Random Pics Of My GA Build
Louie,
Those look like they're just what I'll be looking for sometime soon.
I'm looking at one of two possible solutions right now for my main instruments. Either an LCD pico projector mounted in the fire wall to back project the instruments onto a rear projection surface of some sort, or a monitor if I can find one of such an odd dimension as to have a screen area 14 5/8 wide by 6 3/4 tall. Those dimensions cover outer edge to outer edge of the six pack plus VORs on a 172N's instrument panel. I might get away with slightly smaller because I have not deducted the bezel coverage from that.
Keep the pics coming! You do great work and there aren't enough GA guys out there providing this stuff.

Re: Random Pics Of My GA Build
Will these match industry standard gauge dimensions? For my project I need to fit them into an actual instrument panel frame and be able to put the instrument panel face plate over them.

Re: Random Pics Of My GA Build
3.375x3.550
the depth is around .5 inch
How's Turkey Day going so far? I can't stop eating:sad:

Re: Random Pics Of My GA Build
I ate until it hurt, and then had dessert! Thanks for asking. I hope yours has been good as well.
Is it the square back plate that is 3.375x3.550 ? What about the outside diameter of the round bezel? The openings in a Cessna instrument panel cover are about 3.125" in diameter so I need to be sure the bezels would fit into that.

Oops, I thought you were talkin' about the KI-525A bezel.

Re: Random Pics Of My GA Build
Perfect, so the outside diameter of the bezel ring will fit perfectly. Could I ask for one more measurement that I am not seeing in the drawing?
What is the inside diameter of the bezel ring?

Re: Random Pics Of My GA Build
Ditto, "Outstanding" !
I am starting to experiment with Link2FS and an Arduino to drive the 7 segment displays. Last night I got it working the servo for my flap control and a stall warning horn, next comes the 7 segment displays.

Re: Random Pics Of My GA Build
Tom,
What are you using for the horn?

I assume the pot/lever gear worked ok.

Re: Random Pics Of My GA Build
At the moment the horn is a piezo horn that I am driving with a pulse modulated output off the Arduino.
The gears worked well. The range is a bit short but it's enough to get the separation between flap settings. I did what I thought was a final install today but after looking at it I will be reworking the position indicator and adjusting the opening in my MIP to get a better detent for the third falp position.
