Tom,

Heck, I'd be interested in buying one (or maybe two)  just to have on and.  Getting the machine work if/when needed would be far better than not having a blank in the spares box.  Blanks are good so folks who have done stuff (different caliper mounting holes, , maybe a different half shaft bearing, etc)  could do same on a new blank.  Plus I need to have at least one on hand to replace the one I sold to you. :-):-)

What was I thinking?

The other day I was able to locate and purchase an un machined #10 rear uprite, thanks to Bob Alder. According to Don Anderson this uprite fits the SR 5&6 chassis. The #10 mark is cast into the uprite so it is easily identifiable.

Today I spoke with a foundry and I am considering having a few made using the original blank I just purchased as master for the moulding process. The purpose of this email is to gauge interest among the community for purchasing spares which as you all know are unavailable.
The piece will have to be cast in aluminum as I am unable to locate a foundry that casts in magnesium. The up side is the parts will be hardened to T-6 spec (aircraft grade) utilizing 3000 series aluminum alloy. The down side is an approximately 40% weight increase. Based upon quotes today I hope to be able to offer the uprites for approximately $500.00 each in an un machined state.

Please reply with any interest or comments. Thanks

Best Regards

Frank,
I'm sure the cost could be lower, if amortized over several pairs. Since the SR5 / 6 uprights are the same left and right, with brake caliper tabs on the front and back, they all could be made the same. If you can get combined order, and have one good upright to digitize, I would contact my friend, who did mine:

Gary can make anything.

He builds Formula 1000 cars, and makes EVERY piece, from the uprights, stub axles, chassis, suspension, bodywork from scratch, etc.
Driving himself, he finished 2nd at the 2017 SCCA Runoffs, and won this year in his own car.

    Don,  2 pair?  That comes to $1500 each.   Not all that out of
    sight. If there are 5 of us who would combine order it might
    become affordable. Something to think about.  I had mine welded
    but next season will tell if they hold up.

    Tom,
    Yes it was expensive, $6,000 to digitize and make 2 pairs.
    But, it was my only option, if I wanted to get the car back
    together, using the existing suspension parts.
    There are numerous generic Formula and Sports Racer uprights
    available if you're not staying original.

        Those are beautiful bits. I talked with a local machinist who
        informed me to digitize my uprites and carve them out of
        billet would be major dollars!   On the order of several
        thousand of them. He suggested fabricating the uprites
        using 6061 T6 plate 3/8” thick and thick tube stock for hub
        area.  Weld up in a jig then have the assembly cryo treated
        to reharden it back to T6.  I’m a pretty good tig welder but
        I thought if I could find a used piece I’d be way ahead in
        the end.

        Thanks for all the input gents!  Glad to live in the states
        and don’t have to deal with the FIA process.
