Boeing 737 Dual Control Column Frame
Details added as prototyping continues!
Before you can print anything. You will need some metal work done and some welding. If your good at this skill, the basic structure is created from 38mm square steel stock, 3mm thick. If you can find 1.5mm or 2mm I also recommend this thickness to stop all that unwanted weight (it's heavy - but this might also add to the feel)
Below are two options to try and simplify the process. If you can find a good manufacturing firm to create the steel "U" channel frame
complete with 20mm studs, that's awesome. If not I have created a second version without the pivot studs that can be created on 3d printer. This should really keep costs down.
Dual Control Yoke Full Design:
These drawings are of the metal work dimensions. These include the end studs for 6204 bearings. You must ensure that a 22mm hole is drilled all the way through the bottom of each vertical post to allow the torque shafts to pass all the way through.
Dual Control Yoke Simple Design:
These drawings are of the metal work dimensions. These DO NOT include the end studs for 6204 bearings. You must 3d print the adapters. This is the easiest and cheapest way I could think of to achieve the design. You must ensure that a 22mm hole is drilled all the way through the bottom of each vertical post to allow the torque shafts to pass all the way through.
Both Designs will need:
These bearings support the weight of the control system. They utilise 6204 bearings and are readily available. I have had to 3d printed the support housing due to my location. You probably can get these as a pre-built unit. Just remember the internal diameter needs to be 20mm to match your column studs. If you just want to print them like me, you will require QTY 2. The link can be found here:
These post supports are the interface between the square section control frame to the PVC pipe.
The post supports with the round holes sit on top of the column posts. You will require two of these.
The square centred supports require you to print Qty 4. Two at the bases and two at the centre point of the vertical posts.
