Bonefork,
How bad is the wobbling? My RennSport Wheel Stand locks in very firmly at straight vertical position. There's a just a bit of flex wobble, but the entire stand is quite firm. Is there actual slop and play in your wheel stand?
Yep, mine is solid as well, but IIRC there may have been some play until I messed with the upright angle slightly and then the stopper bolt caught it more firmly. I forget if there are drilled holes in there it needs to catch into or what? Perhaps move it a couple of degrees more or less upright and try to tighten it down again to see if that helps?
12thgear- what part of NoVA are you in? I work in Sterling and live in Leesburg, and have quite a lot of sim gear and projects I've been working on. Maybe we should get together sometime if you're nearby and compare notes.
