Light Weight 2DOF Full Frame Sim

[Liv2Die]

HI EVERYONE! So.. I finally think im ready to post a little about my sim. Keep in mind.. 1. yes my welds are poop 2. I'm running on a tight budget, and last but not least 3. Im married. If you're wondering why i added that in refer to number 2
On that note, if anyone has any suggestions or constructive criticism about my build please feel free to hand me your thoughts, dont worry im a very professional person, you're not going to hurt my feelings

So here we are with my original plans of what i had in mind for my sim, we can see its... well... a penis? not really what i was going for. Did i mention i cant draw?


And of course my initial thoughts for the base..


I finally said ok lets just have a go at it. And uh.. my wife she... TOTALLY agreed..
So i grabbed one of our old race car seats


And some metal for the frame..



Some more...


Annnndddd more..



Found an old toyota u-joint in the parts pile.. (family of mechanics)


And started piecing together the frame..


Built the main of the base from the square plate on top of a square tube er... square


Got some "Wonder Motors" off ebay for 60 bucks a pop (bad idea i find out later)
And cut out some arms for them at 2" center to center (i later made that 1" center to center)


And cut some mounts for them out of that handly C-frame


Installed the mounts and u-joint on the base, along with the motor mounts


And did some dreaming



Decided on er... i think it was 6 1/2" from pivot to attach my control arms


And of course.. Built said arms. Yep you're right, one of them does look kindof crooked doesnt it? haha


Added some legs to the base so we dont go through the "Windshield"


I think we're ready for paint dont you??


Well think again.. Didnt like the way the frame felt to sit on with my feet at the pedals, so adjusted the front area a little and fit it for the wheel setup.


Yeah thats better, now just for a little piece for the shifter


Now we paint!!



WooHoo! G27 came in the mail


And decided on a conduit box for the electronics.
By the way i apologize for not having time right now to type up about all the specifics of what i have stuffed in this thing (ill edit later) but for right now the jist of it is..
30a Led power supply (the one commonly known on this forum)
Power strip (for PS and G27)
Home wall light switch
120mm fan (With red led's )
Fuse block
Sabertooth 2x25
Kangaroo x2
10 ohm pots on the motors
Ftdi ttl converter
err... i think thats it


Ready to assemble!


And the final (cough yeah right cough) product!



Now for the "forum" part, haha. I got about 1 hour play time out of this baby and the cheap ass bushings on the output shafts of the motors developed enough play that the sim was constantly pulsing (because the pots thought the chair was supposed to be moving). This thing was a blast for that 1 hour though! I now have some different motors on order, gonna redesign that area a little and try and mount the pots a little better (sorry i forgot to take pics of the current pot setup). Anywho, let me know what you guys think! If you have any questions or suggestions hit me up!

Good job. That looks awful similar to this:




Or maybe not...

Haha, you have waaay too high hopes about it . Hopefully get a little more structural integrity out of it with a better motor setup but it's still got a long ways to come before it's that pretty

[tronicgr]

I have high hopes because it can be done. I have proof

Oh gosh that looks nice! :p Im not sure i would know where the hell to start with AC power control but it looks like a cool sim! haha. Im a mechanic, so 12v is butter but 3 phase AC might as well be rocket science hehe

[Liv2Die]

I am curious though, the motors i have on order have a long output shaft so that i can support it with heavy duty automotive bearings. However, where the control arm will be connected is a completely smooth 11mm round surface, any ideas on the beast way to secure a control arm? i dont really want to drill through and sacrifice the integrity of the shaft, although it doesnt appear that heavy duty clamping arms are available in that small size :/

[tronicgr]

Try these hub clamps... they come in several dimeter dimensions. Look for one that fits the shaft of your motors:

I used them before and they are really strong!!!!
