    Hi everyone!

    Below is a shot of my current formula-style 2DOF DIY sim, which I'd like to make a couple of changes to.

    The first change I want is to swap out the seat for something a little more comfortable. The current seat is from a local go-kart hire track, and it's OK, but for longer sessions in this reclined setup, I'm finding my back is starting to struggle a bit. I was thinking about folding up some sheet metal to a similar profile to the Playseat Formula seat.

    So first question is - does anyone have any plans for a comfortable seat profile that I could replicate with folded sheet metal? I've seen some wooden sims that have done same thing in plywood, but not necessarily any plans that show that angles that they've been built to.

    Second question, is the general consensus that there really aren't any suitable linear actuators to purchase for a sim rig, at least not for a home gamer budget? I have worm drive motors (https://www.motiondynamics.com.au/worm-drive-motor-12v-24v-200w-180-rpm-20nm-torque.html) and also have a pair of 60:1 gearboxes (mentioned by @noorbeast at https://www.xsimulator.net/communit...ino-powered-race-sim.10722/page-2#post-159608) which I haven't bothered fitting yet. There's a bit of fabrication work needed before I can attach the 60:1 gearboxes, and I'm wondering whether or not to just do linear actuators at this point.

    Cheers
    Nathan

    You could have a look at PT Actuators, but it still adds up to a fair bit, or build your own actuators. But given you have the 60:1s it, plus all control hardware, it seems hard to justify the cost of going to actuators.

    I have no idea about comfort but this covers a DIY Playseat RBR 1 inspired rig: https://www.instructables.com/Driving-Simulator-seat/
