  1. 80-20/Aluminium Rig

    That's a good idea David. I have some left-over from a separate project that I could definitely use for testing it at the very least.
  2. 80-20/Aluminium Rig

    Time for an update I guess. Assembling the rig took about two evenings, around six hours in total. That was after work and while having some distracting entertainment on, so I'm sure it could be done quicker. The third evening was try-it-out-time and it was awesome. My main expectation was rigidity and the aluminium extrusions sure are rigid. The connectors are freaky strong and tighten very well. Assembling it was reasonably easy as far as handiwork skills are concerned. You need to keep the original plan close by though. I had to adjust both the wheel position, seat to pedals distance and pedals assembly angle more than once to begin with. Hopefully the pre-fab rigs you can buy have those things dialed in a lot better, or I probably would have quite disappointed. The way the rig is set up now also means my gf can't even reach the pedals, so I'm unsure if a less flexible rig could even give the full range of adjustment needed for extremely different preferred arrangements (I'm assuming I'm at the longer/straighter end). If you look at a less flexible rig, I'd suggest to try it out first or be able to send it back after a trial period. One thing I'm not happy with and can't do anything about just yet is my seat position. It's too low compared to the pedals and I'll need to order some more extrusions to be able to heighten it. Right now my buttocks are about level with the lower end of the pedals, which allows me to drive fairly fine. However, after about an hour of running I'll notice some stress in my lower back. An alternative to outright raising the height of the seat could be to put it at a backwards angle, to have less stretching load on my lower back while operating the pedals. This should be possible with one additional extrusion (to put below the front of the seat) and two angled brackets. As you'll notice in the photos, the elements supporting the seat are fairly close together, which is due to the mounting points on the seat being so close together. Adding just one extrusion element at the front might give me too much of a backwards angle so I'm currently planning on ordering enough extrusions to raise it altogether and maybe try the angled approach when I get a new seat. There was a bit of a break-in period for me. After a few sessions there were some screws I needed to tighten. When setting up the adjustable elements (particularly the wheel and the pedal assemblies) it's pretty easy to have one side off by just a bit which will give you horrible squeaking until you figure it out and easily fix it. I also had some angle where the pedals are screwed to the assembly, which also caused squeaking and the pedals moving a bit when braking hard. After having figured all of that out it's a dream to use though. Something I'll work on the future is adding a proper monitor stand. The current solution is having my 144hz 24" screen placed on the far end of my desk, which works out fine for the moment. It could be closer to the wheel though and - as you may have guessed by there being an entire end to my desk I can just abuse for screen placement - I had hoped to replace it with a less expansive version anyway. Not having to do everything in one go is an advantage of the system though.
  3. Mounting mobile devices

    Not on the landing page, but under Products they have general devices as well, e.g. http://www.rammount.com/products/tablets
  4. 80-20/Aluminium Rig

    I have an old-ish sports-ish seat from a desk chair that I'll be using for a start. It's plenty comfy and reclines, so it should be good enough. There's a racing store somewhat close (60km) from me which has seats en masse and available for a test sit. I'll definitely go there and test them out. From the looks alone I'm really liking this one: I love the red and the black accents make it just that little bit better compared to pure red versions of it.
  5. All my life my rig consisted of a wheel (as far as I can remember, first a Saitek R4 then a Logitech G25, now a Thrustmaster T500RS) clamped to my desk. After picking up new working desk chairs and with the T500RS, pushing the brake pedal with some force became more difficult, especially doing so consistently. At a friend's home, I was able to sample a VisionRacer rig. It's very high end and subequently also very expensive, so while I really liked it, there wasn't a chance I'd be able to budget for purchasing one. It also looks very nice, which can be a factor for some. For a while I looked around and while I found some visually adequate options, they were out of my budget. For what I wanted to spend, a Build-it-Yourself solution using aluminium extrusions was the most realistic solution. Having a seat to use helps with the budget. My secondary concerns afte budget were rigidity and ability to adapt the rig to my needs. Building it myself and the extrusions being so inherently modular, I don't think you could have anything more adaptable. I'm also unsure about a lot of my exact needs, e.g. distance of the wheels from the seat, height and angle of the seat or the position of the wheel, so having something so easily and extensively modifiable is a big plus. As for rigidity - the extrusions should be quite rigid, and inspire more confidence in me than the smaller tubing elements in other rigs. Even if my confidence ends up being premature, I can reinforce the specific areas myself using extra elements. The aluminium extrusion kind of sim racing cockpit seems to be rather popular in Germany, there's a fairly large group of people discussing such rigs and even some pre-selected sets of elements you can buy directly from a hardware store. This helped me immensely in drawing up my own plans. For drawing up plans, you can use MAY-CAD (available for free), which has most available elements in its database for placement. Here's my plan: I excluded some aesthetic elements, like the plastic caps for exposed extrusions. The black elements are for distinction only. I considered getting black elements, but they are available at fewer shops and the one I ended up ordering from didn't carry them at all. The pedal-carrying element at the left/top is on two hinges, which allow it to tilt upwards, to be affixed at the broader upright elements. The exact placement of the pedals, wheel uprights and seat base are variable along the front-back axis of the rig, by moving the angles affixing them to the two parallel base elements. I suspect I will figure out a basic configuration for them early on and not change them around day-to-day after that. The element which will carry the wheel can be moved this way as well. For the wheel angle and the pedal angle, I picked joints with levers for quicker adjustments. Depending on my final wheel placement, rotating the wheel out of the way for entry to/exit from the rig might become an option or necessary. The materials and shipping came out at around 360€. You could definitely build it cheaper. The six joints with levers alone cost around 40€ IIRC, while normal ones will only set you back a few euros. The wheel support is a bit overengineered to account for me not knowing exactly what I need/want. A simpler solution won't need the extra elements and gussets, saving another 20-40€. The rigs available pre-planned and -selected are available from 160€ to just under 300€. My DIY experience is... limited. I'm interested, but I haven't built many projects in a proper manner. On my desk I have a monitor stand from two pieces of wood (one angled at about 30° for a "surround" workstation layout) with legs, and I built a three leveled shoe rack (from wood as well). I only have basic tools (screwdrivers, some woodworking tools, tongs, wrenches, sandpaper, a saw, a drill - the real basic amateur stuff) available as well, so no manual metal machining after receiving the materials. I hope to receive the materials during the week. The plan is to build the rig on the weekend - if I can muster the patience to wait until then. I'll post more during the build process. I'm curious myself how time-consuming and difficult that one will be. Posts and photos about finished rigs are around plenty, but I couldn't find many ressources on the manual work and time required for assembly.
