    Ok, here goes my dive into my first build! This site has been an amazing treasure trove of info, so I've been grabbing ideas from all over the place. Too many folks to credit.

    Here's some of my basics:
    - Designed to fit within a single-seat 737 trainer captain area
    - Primary use is P3D PMDG 737 flights, so not a lot of wild action, but willing to use for other racing and flight sims
    - 2DOF for now, may expand later
    - I purchased heavier gear motors in case I wanted to build a full cockpit design later (PGSAW 50:1)
    - Not a good welder, so I've been slowly stockpiling 80/20 15 series extrusion and connectors
    - Picked up a sweet 3"x3"x3" universal joint from a military surplus ebay site
    - Not sure if these power supplies are enough, but I grabbed two HP DPS-600PB (47A each)
    - Jrk 12v12 drivers

    I'm still totally napkin designing my overlal layout but here's where I'm heading. I'm thinking that I mount the chair to 80/20, mount the universal joint, and see where we are. I'm worried about using too much bracing of the 80/20 in case I really want to be able to tilt more in racing games so looking for some unique ways of mounting the universal joint to floor.

    I used a simple sturdy mount post, bolted to the aluminium frame, for the universal joint mount on my initial compact rig:

    Yes, I love your design with that post. I’ll keep an eye out for similar materials that i can use use.

    Or I could be overthinking it and I could just make a second rectangle of 80/20 and connect that under the universal joint to make it sturdy, similar to the seat mount. I should just see how much pitch and roll I could get with just the universal joint itself as clearance.
