    I will have 2 at the back under where the 2 seat motors are and the other 2 will be beside the universal, that way I have all the weight coming down directly on the wheels. The will be angled at the radius from the pivot point under the pedals.

    My Sim room in the new house I have just moved to is massive. When I get my rig back home I will have to take some photos of how big the place is.

    It really is nice having a large space for this hobby. I am loving my new man cave as well. :)

    Some more progress photos.

    I decided to make my rig a lot wider than I was originally going to, probably way too wide but I wanted to be able to build in some flexibility in terms of how much movement I can get out of the rig.

    The lever arm for my rear traction loss will have a few different holes at 100mm, 150m, 200mm and maybe 250mm so that way I can play around with how much movement I have.

    Here are some photos.

    [​IMG]

    The view from the front

    [​IMG]

    The front bearing

    [​IMG]

    The rear wheels site inside the frame, just below the motors for the seat mover, there will be a metal plate for the wheels to roll on as well

    [​IMG]

    The front wheels will also run along a metal plate.

    [​IMG]

    The back end of the rig is 1500mm wide. I have tons of room in my new gaming room so space isn't a problem.

    [​IMG]

    Here is a video of how far it could move if I were to use the whole range of movement with the lever arm at its maximum. I will probably end up using about half of that but it is good to have more if I do decide I want more drift.

    Awesome, I look forward to what you come up with for a lever/mechanism to work that TL.


    Edit, err read nick READ!!!! I'm starting to wonder how much travel Can you get from a 100-200-250mm Lever setup.....

    I think I would probably be able to get around 80-90% of the lever arm length in movement in each direction but that would be measured from where the lever arm is instead of at the back of the rig. So if I had it at 100mm then I would have 160-180mm total movement at the lever arm, the 200mm would be 320-360mm and the 250mm would be 400mm-450mm.

    That is just a rough guess. obviously I wouldn't use the whole of the movement on the 250mm arm but it would give me a different speed of movement so I might say use the 250mm but then only use 50% of the axis. I don't really know which is going to feel the best so I am leaving my options open so I can experiment with different length arms.

    Some more update photos

    The rear skid pads

    [​IMG]

    The adjustable frame mount for the push rod. I will be able to move the push rod to different holes as I move it up the lever arm. On the lever arm I will have a hole ever 35mm so I will have 100mm,135mm,170mm,205mm and 240mm to pick from so I will have heaps of tuning options.

    [​IMG]

    The front wheel support rails, this rig rolls really smoothly with the 4 wheels.

    [​IMG]

    The motor in place with the spacers needed so the drive shaft clears the bottom frame

    That is a long way to slide for traction loss. I would imagine at 100% of the travel to one side it might put your arms at an uncomfortable angle with your wheel. Looks awesome though.

    Yeah, she rolls really smoothly, those wheels are perfect for my sim. So pleased with them, they are double ball bearing and can take 300kg each so they will last the life of the rig

    The whole upper frame moves, including me and the wheel so the angle between me and the wheel doesn't change at all.

    Some more updates.

    The water cut lever arms.

    [​IMG]

    They will go together like my old lever arms

    [​IMG]

    I have started work on my flight control mounts. This is my throttle mount.

    [​IMG]

    It is hinged so I will be able to get in and out of my rig, I am looking at securing it closed with neodymium magnets

    [​IMG]

    I love the look of bent tube steel, it reminds me of headers on a car engine.

    Thanks.

    Yeah, I love being able to design and cut things on the water jet cutter, it is probably my favourite bit of kit. So many part for my rig have been water cut.

    The workshop where we are doing is really well set up, they normally build race cars so they have all the tube benders and welders that they use to build roll cages. The fabricator who is helping me out is really talented also, he does amazing work. They also did all my work on my 1975 Hillman Avenger which is a beautiful car.

    Some more progress photos.

    We attached that seat so I could have a sit in the simulator to see how everything fits ergonomically, everything is in the perfect location. We also tried out the motion of the rig by just moving it by hand with me sitting in it and it rolls super smooth.

    The flight stick in place

    [​IMG]

    The bottom mounting plate

    [​IMG]

    The quick release top

    [​IMG]

    The newly revised throttle mount, I had to step it out a bit further so the seat had enough room to move

    [​IMG]

    In it's closed position

    [​IMG]

    In it's open position

    [​IMG]

    I just used a little pin and hole to lock it in to place when it is close

    [​IMG]

    It is stepped off to the side enough so I can still use my H-Pattern shifter while the throttle is in the closed position.

    [​IMG]

    I had to reverse the hinge and move the transducer a bit to get it to all work and clear the shifter.

    [​IMG]

    I start on the pots mount.

    [​IMG]

    And we got the keywayed center back from the machinist

    Brilliant attention to detail, as always :thumbs

    I would really enjoy a video covering things like the quick release and throttle mount, if you get the chance.

    Thanks. I will do some videos on all the little bits when the rig is finished.

    Thanks guys. I am really happy with the throttle mount, it took about 3 or 4 prototypes but I am finally happy with the design.
