2DOF compact race / flight with Oculus Rift

thank you or the references @noorbeast
so if my lever is 4", motor is 75RPM, linear speed is 2.8 feet per second which seems to be more than enough?

@noorbeast thank you for the very detailed explanation. i will stick with 60 mm CTC with some additional pre-drilled holes to give me some range to play with since it is hard to tell what is the best torque and speed for the application

i wish there were more ratings to give ,
thanks for taking the time to provide the info.

You guys are juts a bunch of troublemakers I was happy with my 2DOF+drift until I saw a thread from Boomslangnz 2 Dof Motion Sim Retrofit. Of course now I am thinking that adding a surge might not be a bad idea. It is a lot easier to incorporate it into the design now instead of trying to retrofit later. The problem is I am over my budget and this will easily add $300. So a couple of questions. I am planning to get 25:1 motor for this instead of 50:1 used for my other three DOF. I don't think I need as much force for surge and the eBay seller I bought them from no longer available. ANd would this be OK for the linear bearings, they are quite pricey.

thanks guys

i know, this is how i got the idea. what is the general consensus, is surge worth the trouble or am i overcomplicating things?

sorry! haha
Not too many seem to add surge to be honest but I thought it looked cool and would definitely add to the sim. The linear rails aren't really cheap but they seem to work really well, I actually am using the SBR30UU ones myself however the SBR16's may be more then enough I just didn't know what they could handle and it wasn't too much more expensive for the bigger. Depending on your design you may not need that long rails either, my rails are 880mm long in total but I am only using 320mm movement in total of that which I feel confident will be plenty so depending on your design you could drop the length which saves in cost! Yes im using 25:1 motors and considering I can move it back and forth with a single finger with ease then im sure it will work fine. As for if its worth it? Ill let you know once its running soon but I asked the question in the previous few weeks and everyone who had it said yes...its worth it. Apart from noorbeast and his linear rail design of moving pedals etc I think im the only one to try a linear rail for surge in this way but you could also try a similar way using castor wheels or even roller blade wheels or anything of the such which could be a cheaper design for a similar result. Its never too late to look at it later if needed anyway

Yes, you are the troublemaker who planted this idea in my head . I already welded together a separate subframe for the surge. I think I will move on to the seat frame at this point to see how you like yours and if it is worth it to incorporate this into the sim. Most likely will use SBR16th as they should mount nicely to my 1.5"x1.5" square tubing I used for the frame.

Could someone tell be the difference between V1, V1.5, and upcoming V2 of Fanatec Clubsport Wheelbase? V2 is not even available yet, but by the time I am done I am certain it'll be out. I am considering buying a used one to save a few hundred dollars, not sure if this is a good idea or not. Thanks.

i could get used V1 for half of that, that is a lot of dough

Some progress to report. Lower frame is completed. Provisions for surge and traction loss.

each is rated for 110lbs, very smooth. if anything they are more quiet under load.

V1 - 5.2 NM
V1.5 - 5.2NM, improved motors to prevent fade, updated encoder (original was prone to centering issues), updated internal ribbon cable (V1 tended to rip)
V2 - 7 NM, updated internals and look

thank you
