The 'mountain' car is on hold, waiting for the sandblast / soda blast guy to open up his shop.

Kerry, Steve: The following is info about the cars discussed in this thread, but if you think that it is to far 'left of center' feel free to modify/delete it.

Hey Pugsy: Here is some information that might be helpful for you in making decisions about what type of suspension to use. Everything that I worked on in the race cars was independent front suspension and a rear end housing assembly retained by a pan hard rod.These 'sketches' are part of a vehicle dynamics project that I have been working on for many years and were used as guidelines for both the 'mountain' car and the narrow Talladega car.

The first three 'sketches' will be helpful in determining the center of gravity. In cornering, the G-forces will tend to make the CG rotate around the roll axis. (Fig.#19). The front and rear heights of the roll axis are determined by the roll center heights at each end. CG height/location can be determined by (Fig.#15). Front roll center height can be determined in accordance with (Fig.#16). On the solid axle/pan hard rod design, the roll center height is the center point of the pan hard rod, left to right.

This information is more dependable/useable if the frame is more stable/rigid. (Fig.#12A) is the method that I used to measure the torsional rigidity on both of the cars in this post. PM or email me if I can help.

Thanks Will.
I do have a program for the computer, but not all this info is available.

Got out of the house, put on my mask, and went to Bills shop to deliver some pieces that I cut for him and got some pictures of some of the components that he has worked on so far.

Those drawings are great stuff, it stimulates the brain. I love the old NASCAR racing. The new stuff is too regulated, no room for individual innovation; although they are certainly well designed. Design wise they have all evolved to be very close to each other. Engineering of new cars has brought new cars to be almost all alike. , They all look alike where the older cars had their own look and design. Thanks for the pictures and drawings

Thanks, Ed.

There has been some current interest in this 'old' book recently. I thought that I had all the pages on file on my computer, but a 'crash' issue a number of years back, lost me some of my CAD files, but I have just received one of my older copies, so I will be 'updating' that chassis book when the 'story' book that I am working on is done. One or two of these drawings is going to be in the 'story' book in a story about a 'thin' car that I built that recent research showed was the worlds fastest stock car for three years.

The 'mountain' car has been completely stripped now, and all the suspension has been restored and painted. They are waiting for the sand blaster/media blaster to get caught up on his backlog.

Bill Rhine called me today to tell me that they are getting the car ready to take the car to the sandblasters tomorrow. It looks like things might be starting back up. He said that he has contacted the painters and made arrangements to take it to them when it gets back from the sandblasters.

He said pictures will be coming soon.

That was interesting Tom.

Bill told me last week that the mountain car was still at the body shop. I am getting excited to take a look at it. Bill said that they have most of the suspension items cleaned and painted and ready to install once they get it back.

I have built race cars that Bill Blair, Jr. built the motors for and have worked with Tex Powell over the years. He is an excellent fabricator and does/did? most of the transmission and rear end gears for the NASCAR guys. They are both highly regarded gentlemen.

Thanks for the post.
