Marbz... I'm sorry but I have been busy lately doing other things, especially with my work load which is always increasing.
Currently, I am away from home for 4 days and will be back home on Sunday. However, I can give you some information from here.
Start off by purchasing / getting your seat, reason being is very simple, the whole cockpit has to rotate around the seat.
When you have the seat, than put your seat in front of your tv set, sit in it, and start taking note of the height of the tv when looking into it. I find it really really comfortable to have your eyes exactly in the middle of the tv, hence make sure that when sitting in your seat, you eyes are looking directly in the centre (height wise) of your tv.
I think that when building this type of cockpit, where you are very limited with the type of adjustments you can make when the seat is done (except for the seat position if you put it on runners like I did) it is important that you build it custom made around yourself.
When you have taken note of the height you want to install your seat on, start working a box to mount your seat on. The box has to be big enough to attach the seat comfortably enough on it. If you browse my early pictures, you will note that one of the sides is higher than the other one. This is done on purpouse so on/with it the shifter holder has to be attached. This is also something very personal. Some people prefer the shifter to be installed high up, almost next to the wheel, while others prefer it down next to their knee. This is up to the individuals discretion. So make sure that you calculate where do you want your shifter to be placed, and work also with it. Beleive me, it took me much more time planning and taking calculations and dimensions so it fits me comfortably than cutting, building & painting wood. This is a time consuming process, but it has to be done if you want to have a good final product.
I would start off taking these dimensions first, and start building the box to mount the seat on. If you want, prepare the chasis of the rig as the seat housing box itself has to be mounted on the chasis. My chasis is around 2m long, but I cannot give you dimensions at this moment.
This is the information I can give you:
- I used 18mm pine boards. MDF will be fine and also 16/18mm plywood.
- The chasis is made of white wood beams, 45mm x 22mm. They are strong enough to be used as chasis as long as you are not going to keep you racing rig in the water (which I doubt)
- If I'm not mistaken, the height of my seat housing box is 250mm from the ground, however, I'm not 100% sure, but 85%. I will check for you on Sunday.
- I am 1.73m tall. If you are somewhat in my height range, my dimensions could be fine. If you are much taller, you'll have to construct it on your own dimensions.
- Make sure that you buy your seat with runners, as it will be much much simpler to do some final adjustments to your final position. Remember that the seat is the only part of the rig you can adjust, pedals, wheel and shifter will all be fixed.
Hope this helps. I will have limited access to the internet, but I will try to answer you if you have any questions. When building your seat box, check some pictures I've posted on Page 1 as there are some images showing how I gave support and strength to the seat box as that part of the rig will take all your weight, and you don't want to end with the seat in the seat box while doing 250kmph in the eau rouge and radillion hehe
Enjoy your build... if you do not enjoy it, your final product will not be nice, and it will show

Any questions, feel free to ask.
