Hello all,
After selling my 737 project, I'm now going for a 1 seat GA/Multisim. My aim is not to make it look like a specific model, instead I'll design a Multisim that can be used with a piston or a 737.
So far I've purchased BFF control loading electronics and servo motors, a OEM gear switch, OEM trim wheel, OEM PA34 TQ and a OEM yoke.
My plan is to use oem on all main controls. Looking to buy rudder pedals and a nice seat in the future.
For flaps control I plan to use a momentary switch so I'm not limited to detents..
The progress will depend much on how much time I have to work on it, so it's a long term project.
I'll start with some pictures of the trim wheel unit.

Trim wheel unit.
Based on BFF trim wheel electronics and an OEM trim wheel from a C150 series.
The unit uses a mechanical linked trim indicator, so no servo och calibration of the indicator. It uses the OEM spirals on the side of the trim wheel.
What's left is the facecard, it's a temporary solution right now. I'm going to a company locally who makes stickers. I hope they can produce something I can use.
Stepper motor with housing, sensing pot and dsub connector.

I also added a shrink tube around the spring so I got rid of the annoying sound [emoji4]

Hey Steve,
I got the idea of a friend of mine. It was very effective [emoji16]
Work keeps going on. I've done some work on the throttle lever. Designed a pcb and ordered from pcbway, fast cheap and good quality.
I'll use a OEM PA34 TQ, this stand for the pcb will connect to the levers by rods. Mounted on an angle to keep them as linear as possible.
Also been working hard on the parking brake mechanism which turned into a 737 project. I'll make the parking brake like on the 737, I'll also sell this product on my shop. I think its gonna be really good addition to many sims as it work just like in real life. Separate post for that though..

A side project I'm also doing for the Sim are the gauges. I love steam gauges, my plan is to use EADI + EHSI on lcd screens and everything else using steam gagues.
Here's a prototype I'm working on.

Moving along with control loading. All materials are now on order and should arrive within a few weeks.
Design is almost finished, some small items to fix/change and some features to add but not much work left.
Looking forward to start producing these parts.

That looks interesting. What does something like that cost?
All in all, it's quite expensive with all the electronics etc.
Mechanical components is around $4-500. Most purchased from aliexpress.
Motors:

Electronic components from Ian in UK:

Then add power supply and some other components.
I purchased a OEM yoke on ebay also for this project.

Project will be continued in about a month or two.
Been working on my cnc machine lately. New vacuum table, vise, spindle etc.
Also been working with a new electronics rack for the control of the new spindle. Now I'm going to control spindle rpm through CAM.
Also I'll be able to control vacuum cleaner etc via software.

Travel endstops mounted.
Also aligned the guide rail so it's straight. Next up is the mounting adaptor between the shaft and the yoke. It will be a quite complicated part to produce as it has more complex form.
It will be a new challenge but also fun to learn.

CAM done in F360. It took quite some time before I could figure out how to setup the part in a 7.5 degree angle.
I'll have to mill two fixtures to hold the piece. I'm at the moment out of aluminium so no machining until next week.
Gonna be interesting to see if this works. If anyone has experience of this, please shout out [emoji16]

Small steps forward.
Today I machined the part that attaches to the yoke. It has a 7.5 degree slope, the other part that attaches to the shaft also has 7.5 degrees slope so the yoke will lean 15 degrees in relation to the shaft.
Quite happy with the result. Some improvements if I where to redo the part but in the end it doesn't matter. Would just help out to make it easier to mount.

Beautiful work on these parts Anders!
CAD/CAM in Fusion 360 is very convenient, although it is not intuitive -- especially when it comes to creating geometry using multiple planes.
By the way... Your Start Switches are still working fine in my 737 Sim. "They take a lick'n, and keep on tick'n" :)

Hello Archen,
Regarding AutoCAD's Fusion 360... Here is a very good set of tutorials for using Fusion 360 in CNC applications. I purchased the Fusion 360 for CNC Lathe work. It is very comprehensive as to each step needed to setup and use the CAD/CAM operation in Fusion 360. I think it could be of great help to you. Here is the link:

Had to make a new shaft, I made a mistake in my design so it was to short.
Now it will leave around 15cm space behind the panel and also 15cm between the yoke and the front panel when it's mounted in the Sim.
Lots of work as the bearing was heated to make them fit it was very hard to get them apart. I'm not taking it apart again, that's for sure [emoji16]

Designed a bushing to support the shaft in the front. It will be manufactured in Acetal (delrin).

Would a flange bearing be a better option there Anders? Assuming you get get one the right Size for the shaft... Just a thought!
It's looking magnificent none the less. :D

Hello Joe,
I think a hardened shaft is a must if I should use bearings. The shaft is not hardened unfortunately.

Machined the part today. Now it's going into the lathe to trim the outside diameter and also make the inner hole the right size. I think I'll do h8 tolerances, seems like most bushings are h8.

Two new pics showing the casing.
Ideas how to make the 7.5mm radius bend?

You could use a brake press, like the one in this video:

I made one using birch plywood for bending aluminium. to form a radius you simply machine the inner radius on the part you're bending it around.
I hope that makes sense??
Joe.
Many thanks Joe! [emoji16] Great idea
