2 dof seat mover with cv

I will buy flex couplers then didn't think rubber hose would flex too much.

I've bought:
2x47A psu
2x jrk 12v12
4 ball joints
2 wiper motors (now isolated)
Heat sinks
2x 1 turn pots

Do I need more?

I've started the build.

20x20x1.25mm steel tubing, light and sturdy enough i think. Ran out of tubes...

Made a frame and welded the cw joint to a base plate, seems to work perfect.

Did you get it balanced properly ? Or have you build in some adjust ability to get it set properly ?

I've balanced it using a steel pipe under the seat frame in the right height, should be accurate

Got a little further:

Still missing some parts that are beeing shipped.
Thinking about covering the frame in some cheap carbon film, just to make it a little racey

Do I need both 47A psu's to run the 2 wiper motors? Seems like a lot of power?

Mounted the wheel as low as possible to mimic a racecar, but found out that there was no room for my knees when the seat moves :-(

Had to cut up the frame and move the wheel and the screen up...

Mounted the wheel as low as possible to mimic a racecar, but found out that I would hurt my knees when tilting forward :-( So had to cut up the frame and move it 80mm up.

Looks good! I'd suggest adding a little bit of support, and possibly using the threaded hardmounting points under the front of the G27. The clamps on mine ended up breaking (someone trying it out got a little bit too enthusiastic). and the RMA process is a nightmare.

Also, from the photo it kind of looks like you have your wipers mounted with the shafts in the rear rather than facing the sides. Is this the case? Or are my eyes just playing tricks?
As far as power goes, you already have both supplies, so it can't hurt to use both . I'm powering both of my motors from a single supply, but it's capable of 60 Amps, so it's probably got a bit more capacity.

I will make supports for the wheel, it was just too see if the hight was okay

Yes the axles are pointing backwards, I guess it will work out to the same movement?

It could work, just that I've never seen it done that way before. It depends on how far you've angled your motors inwards with respect to the base platform. Ideally if you were going to do it that way you'd probably want them to line up with where you want to mount your motor arms: (excuse the poor drawing)

​

Like I said, usually it's done with the shafts facing the side, as this takes care of that alignment for you, but don't let that stop you from trying your own way out if you want to!

edit: When I look closer I'm not sure if they're mounted the way I originally thought they were. Do the shafts of the motors point out sideways from the platform, or are they pointing to the back of the platform? A closer shot might help .

They are pointing backwards, I thought it looked better, the motors are angled, so i can't see why it shouldn't work, but i'll soon find out

Hmm interested in how the motor mounting solution will work. I haven't mounted my motors yet so hopefully you are close to a test run so I can decide how to mount mine. I do like the aesthetic value of your design

Not too close, the things I bought off eBay takes forever to arrive...

Progress is slow as I am waiting for parts, but a managed to find the harness from my samurai offroader

How long levers would be best? Have read a lot, but as most of you use bigger motors I don't really now what ctc length to go with?

Okay, maybe I will make 40, 55 and 65 then, have never seen or tried a simulator, so I really don't know what to expect... But I found out that just a stationary rig makes a really big difference from sitting in the sofa!

Okay

did you get the powered up yet? I curious about the motor mounting solution
