Hi all,

My name is Bob Russell (formerly Punko353) I ran Team Players Virtual Garage which was a rFactor modding team.   I had worked on the GPL 55 mod prior to starting up Team Players.

I recently decided to remodel the cars of 55 for my own enjoyment and am planning on doing them in very high detail.  These are not being done for any sim since they will be way to high of poly count.

I would like to know if there is anyone that could help me with some of the details (suspension drive train) that can't be seen in pictures.

I am currently working on the Gordini and am stuck on the rear suspension.

If anyone has knowledge and can offer any help I would be quite great-full.

I posted some pics so you can see what I am doing and they can be found here:

NOTICE:  
No need to respond in this thread since I know this is off-topic and I don't want to disrupt this section of the forum.

Thanks for any help that can be given

Cheers,
Bob

@KARTM,  Thanks for that pic, I have one I think is the same image but it is so small I couldn't make out any details. That is a great shot.

I would like to also do the type 32 but that is a ways off since I have the Maseratti, Ferrari 625 and D50 started but much to be done.

I know the T16 had a solid rear axle but just cant find how it is all connected to the frame.

Thanks again :)
Bob

I don't know if it's helpful, but there are modern pictures of the 50s era cars and more at http://www.gurneyfla...ormula150s.html

Note that the Gordini T16 of 1952 had it's gear shifter right between the driver's legs!

I've built actual models of 3 of the 55 series cars (Lancia D50 ... note my avatar,  W196 Merc and a '57 Maserati) so I have quite a collection of good images including a series of "body off" front and rear suspensions of the D50 taken for me by the REVS institute in Florida where a real one resides.    I'll be happy to share what I have when you're ready to work on any of these 3.   Might be best if I send them through Dropbox if/when you're interested.

@Bob Simpson,   Hey Bob, Its been a while, good to see you are still around the forums.   I do have that link to gurneyflap but thanks.   Yes, when I first saw where the gearshift was my first thought was how the heck are you suppose to drive and shift at the same time...


@KARTM,  that first image is about all the detail I could find as to what the rear suspension is but have no idea of where that swing arm goes (if that is what that is).


@akbergman,   I saw those models when genetto first set up that 3d model section and have to say I am very impressed!   I have been into building models since I was a kid.  I have built a couple of small wood models in the past but always wanted to try and build a large scale one.  I know the kind of time you had to spend building those so "kudos to you"  

Most excellent work!

Cheers,
Bob

@webfoot, Thanks for the link,  someone already sent me that link but I really do appreciate the help :thumbup:

My biggest issue is how the rear suspension actually works.  I can see the fixed rear axle and it appears to be an independent rear suspension similar to the front with the torsion coils (or what ever they are) connected to the upper and lower A arms (or I arms in this case).

I am curious as to what they are actually.  I assume they have a coil spring in them that twists to provide torque.

Thanks again for the link,
Bob

Yes I saw somewhere that they said it had a leaf spring in the rear but this is what I can not figure out.  If you look at how it is setup it has almost the same A-arm configuration as the front with some other arm included.  I tried to figure out if that was a leaf spring going horizontal with the rear axle it doesn't seem that it would work since the spring would put torque on the opposite side of the car.   That seems to defeat an independent suspension setup.    I realize that this was back in the 50's and it was a time for experimentation but that seems to defy logic.

I have been searching for a long time for this info and don't think that there are any pictures of the car with the rear body off.

Perhaps I need to try and find someone that actually owns one or someone that has seen it first hand.

Thanks
Bob

Quite common in open wheel racers from the thirties through the fifties;  wouldn't you feel comfortable in this '48 Kurtis midget racer -
