No check engine lights. If it doesn’t sells I will continue to autocross the car in spring. 196,xxx miles.  Asking 1600 obo.

    Great work man! You may also consider using oil impregnated solid thrust washers instead of roller bearing thrust washers if the loads are low enough and you want to improve environmental protection.

     

    The castle nut is a great idea

    I would like to possible try 3d Printing some bushings for weather protection. Out of some soft filament. Or Nylon

    With some help from RobZR. I believe we have reached a much safer option from using a shoulder bolt. I made up this spindle design last night. This will have a castle nut and cotter pin in its end form. I did tighten it all down and I’m very pleased with how it turned out. zero play.

    CAD to Metal overnight. I like your fast pace.

    What did you use to cut the parts? Waterjet?

     

    I work In a Tool Shop so i May have utilized Our CNC Laser.

    I did have some of this work done Prior to posting the cad up date. 

    Its been after hours progress the past 2 weeks . I have 3 of the 4 Control Arms done. So you should see up-dates later this week.

    I would not recommend using a stripper bolt in this manner. They are not intended to handle lateral forces and have a inherent stress riser at the base of the thread that is prone to failure.

    Ideally you would support both sides of the pivot point from the subframe.  if you must support it from one side a spool and bolt design will bend before failure, since it keeps the bolt in tension.

    I 100% agree with you. If you are using a Harden alloy shoulder bolt. But with that being said I will be mostly turning up a custom shoulder bolt . But any side load should be transferred to linear load with the thrust bearings. Not 100% transferred but lessened a great deal. I’m not saying you wrong in anyway and I will take any input I can. 

  7. Quick update. with some actual fab work being done.

    The past couple weeks I have been putting in some hours gettin some of the front frame done. I’m gonna attach some photos if you have any questions let me know. I’ll try to explain.

    Yeah this project was always intriguing, but has certainly caught more of my interest seeing things being modeled!

    The shear area on that upper shock mount seems reasonable if you've got good penetration welds on both plates. 

    I think I saw the knuckles in a picture on a previous page, but are those a standard purchased component?

    I've always thought it would be cool to do a ground up build like this, so I really look forward to the continuation of this!

    The Knuckle is a ford Pinto Spindle. Primarily Used in circle track applications.
