    Blazer building 101

    ntsqd, Yep, the Jeep parts are the same. Make sure you get the correct snaprings to lock the spline drive to the axle shaft-personally, I'd use full circle style lock rings and machine the groove a bit wider to accomodate them-a bit thicker, but they won't "spread" like the OE 44 stuff under...

    I'm back...

    Re: I\'m back... Sorry, but no photos. Under the terms of the sale, I had to turn over all non published documentation and photographs. The only image of the system was an early 3D model that I used to illustrate some suspension concept discussions, here in an old thread. Search for my name and...

    I'm back...

    Re: I\'m back... The system worked flawlessly. The OE involved liked the system and purchased the rights to it. When (or if) it comes out on a production truck is unknown to me....glad you remembered.... Best as always, Bob

    Welding on hydro formed frames

    Actually Bill, the hydroformed frames are stiffer than the previous generation...there are crush zones (identifiable by the "darts" and "dimples" in the front) that are designed to bend. ntqsd is quite correct in that you should have a "brick" (high natural frequency-meaning a really, really...

    J-Arms

    This may sound silly, but if you can "add material and points" (BTW-if that is a quote-I see it the same way), then why not bellcrank them to the UCA (of whatever type design) to increase the leverage ratio, make the shocks you can run more effective, AND get them up under the hood out of the...

    Pirelli Scorpion A/T

    The original Scorpiuons were developed for Lamborghini on the LM002 (the "Le Moo Two")for the Saudi military. In the Mid East desert they were the only tire that could meet the specifications required for holding the power of that v12 and the speed of the LM over that terrain. Goodyear, BFG, and...

    Material stregth question

    There is a good little program available for download on www.download.com (I think) that I have been using for a few months now called "Engineering Power Tools v1.9" that can calculate that for you. You have to use a couple of the functions, but for anyone that is educated beyoud simple addition...

    I'm back...

    Re: I\'m back... Heck, I figured that, after that long dang thread on the hydroistatic drive system with Model T derived suspension, people would have thought I was locked up in the booby hatch somewhere for life....LOL!! Anyway, it's nice to be home-thanks guys... Best as always, Bob

    has anyone seen any of these SAE documents?

    Sorry if I appeared to denigrate or "put down" anyone on here...my meaning of the "homebrewer" comment was that all of the writers of those mentioned papers are professional suspension and vehicle dynamics engineers with years of experience and statistically, they have a big edge over the...

    has anyone seen any of these SAE documents?

    I have read all of them and all have points to make that should be considered WITHIN THE INTENDED APPLICATION. I am NOT saying I agree in all instances with the included conclusions, but overall they make compelling cases for specific advancements far over and above what the "homebrewer" can...

    Center of Gravity

    Re: Fabricator -- care to elaborate? I like the comment, but would change one thing "...the wise man knows when NOT to use them." Seriously, what is being discussed here is about 12 to 15 years behind the automotive industry as a whole (knowing the whys and wherefores of what makes a vehicle...

    Racecar Designing 101

    <IMG SRC=http://www.race-dezert.com/wwwthreads/files/6-17620-pt001.gif> Kinematics, finite element analysis and other functions have been discussed previously on the board- for examples, go to the search page here and type in "CATIA". Just as information on what can be done with other programs...

    Solid Axle Chevy Steering

    Simply put-caster gain has a higher priority than toe change for an offroad vehicle. For a street dirven vehicle, the reverse is true. That being said, my PERSONAL preference is to design in (on a race car that does NOT use a TTB or TIB) a caster change to increase the castor about 25 percent...

    Solid Axle Chevy Steering

    You have understood the concept..... a couple of caveats however.... 1. The Haltenberger linkage is used to create toe-in during rebound (commonly called "droop"-incorrectly) to increase the overall vehicle stability when launched airborne. This is one reason the TTB/TIB Fords are so easy to...
