2 DOF project

Hey all, finally decided to move up from my static rig after seeing all the great motion sims on here.

Currently using a PVC rig (attached image: don't mind the missing shifter mount and tv mount; got lost during the move), and was considering just adding a seat mover to the back but plan on doing TL at a later time so I figured I might as well start the frame now.

As far as rig design, I plan to go with something similar to the rig @Avenga76 built.

Current shopping list:

1. JRK 12v12 (x2)
2. 25:1 gear motors from pgsaw
3. Server PSU (x2)
4. Hall Effect Pot (x2)
5. Tie rod ends
6. U-joint
7. Flexible couplings for pots

Anything I'm missing or any other suggestions?

Couple of initial questions:

I already have a lot of square tube steel, but what size would work best?

Would it work better to use my seat slider to move my pedals or have slightly smaller square tubing that could slide in with locking pins?

Already have 2 emergency stop switches I had lying around. Same with fuses/fuse holders. (I'm an electrician/master maintenance tech by trade). Good point on the usb cables, guess I haven't thought enough about all the small details.

Hi.

Good to see you have a build thread up.

For the adjustablity. When I first built my rig I tried to go for the old slightly smaller square tube trick but it became a real pain as my rig got heavier and more complex.

I switched to just using a seat slider for the pedals.





For box section size, I use a combination. The outer frame of my rig is all 35mm and then my seat frame and some of the connecting parts are 25mm.

Fuses and killswitches are a must. I have 2 killswitches on mine. One up the front where I can hit it while driving, and another on the back of the rig so I can kill it if other people are driving it or while I am tuning it etc. I have a ton of uses all over my rig, about 6 all up, dotted all over my rig. Once you start adding moving parts then you have to be more careful with cable management and electrical protection.

whats about buttkickers? i will buy 4 today, for use with simvibe soft...

Alright, long time since I posted but I'm finally ready to begin. Purchased my motors and steel tubing to start fabbing up my frame but I have a question on design. I opted to go straight for a rig with traction loss and a seat mover but I was wondering if I should mount the monitor to the traction loss frame or keep it static. It wouldn't be affected by the seat mover but would turn with the rig when TL actuated. Would this be realistic?

well, realistic is, but of course the ideal would be the screen moving along with the rest. It depends a lot on the focus of your design ... moving the entire frame along with the cockpit, your body and the screen requires a force that few engines have (logically speaking in reasonably priced engines)

I know it'd be a lot of weight for the motors if I was doing a full frame and trying to move the TV with the rig. I'm assuming that a 50:1 would be able to handle moving everything on a rotational axis though, since for this motion its not really having to fight gravity so weight shouldn't be as much of an issue. Correct?
