    FS: New window winder/regulator pivot pins - thread 2

    Not sure what the basis of a 'closed thread' is, and who makes it so, but I guess I'm about to find out. I have therefore relisted my post. If this is a heinous crime can someone advise me why, and what the original offence was.....It seems at least one member thinks I'm selling substandard goods here, but is not prepared to tell me and my buyers what it is that makes them so. I quote from his last post "Your assumption is completely wrong about fitment, by the way. You figure it out."

    I am not in this to make money just to meet what I thought was a need of Porsche enthusiasts - all the proceeds go to my mate who takes a lot of his personal time to make these out of offcuts of expensive alloy. I will happily desist if anyone can advise why these will not be at least as good as the originals. I have no desire to sell crappy goods, nor to deceive. I hold this forum and its members in high regard and a number of them have been most helpful to me - I am just trying to give a little back.


    Original post

    Having been astounded at the eye-popping prices to replace these pins (circa $30 each at Stoddards and Sierra Madre, £32 ($48) at Roger Bray in the UK!) - and they are inevitably are broken or severely worn in any early regulator, resulting in stiff or poor window movement - I have talked an old mate who is a professional toolmaker at one of the European racing team parts suppliers into making me some. I needed 4, but he has made 8, so the rest are up for sale. They are made from 7075 Aircraft spec Aluminium Alloy, and can either be peened over to hold them in place (as per the originals) or drilled and tapped on the end for a M4 washer and screw. (I do the latter as it's more secure I feel). These ones are slotted for the spring parallel to the support slot. If there is enough interest then I will ask him to make more, and some perpendicular to the regulator slot if required.

    18$ each for a single, 15$ each for 2+, plus a fixed 5$ airmail shipping from the UK for any number up to 10, so if there is enough interest a single packet to a local group might work best.

    Update: All sold but I am also gauging interest to see if it's worthwhile twisting his arm to make more. If you are interested them please specify the amount and spring slot orientation (parallel or perpendicular to the regulator slot). Like all craftsmen he is not the quickest, so don't expect 'Next day delivery' if we have enough interest for another batch..........

    Further update: if you are concerned about the material used please see later posts.

    Further further update: These are 26mm pins

    Furthermost update: more available see my last post!

    Just trying to maintain decorum here. I was concerned about where the last thread was headed. Also, you had indicated "All sold".

    Well you'll also see that I was seeing if there was anyone else interested .... and there is, despite all the unhelpful comments. Shame if they're disenfranchised in the process, don't you think? I think a pm to me explaining your action might have been courteous also.

    Perhaps if you could use your influence to see if Jim will elucidate on his comment, 'Your assumption is completely wrong about fitment, by the way. You figure it out' so that we can see that he is equally interested helping in solving peoples early Porsche problems as trying to marginalise someone who unwittingly has introduced a product that seems to be in competition with his own. Again I quote, 'We make all of them out of mild steel'. I say again, if I in good faith sell a product that a regular contributor to this forum has sound scientific and/or engineering knowledge that suggests said product is not fit for purpose, and says nothing but 'you figure it out', then I think it is clear to all who read this who is the pisser and who the pissee, relative to said parade.

    This will be the very last time I use my experience, and my mates time, resources and expertise, to try and help my TransAtlantic colleagues unless there is some clarification from Jim...

    Rant over. Y'all have a nice day.

    Thanks for all the pm's.

    Today I fitted one of the pins and have taken a few photos for those who might be interested in how easily this goes together.

    First I had removed the old pin by grinding it flush and punching it out. I favour drilling the pins and tapping M4. Then noting the thin washer that goes between the two parts of the regulator, apply a little grease, align the slot on the pin with the one with the outer regulator and tap it home. A bit of Loctite or threadlocker of your choice on the M4 screw, fit a large enough washer to overlap the end of the pin and tighten it in place. Refit the spring and you're done. Took me 30 min.

    Just had another batch arrive (in splendid packing I must say!) from my toolmaker friend. You will note he has already tapped the base of these so you can avoid that step. I need 4 for myself, but the other 8 are available if anyone wants them. Please do read the comments in this thread and its predecessor (same title but w/o 'thread 2') so you are aware of the issues that have been discussed. These all have the 'spring slot' parallel to the 'regulator slot' and are 26mm long in total. Please check yours are like these.

    Price as above. Any comments (good and bad) from previous buyers appreciated

    Mick,
    Since I missed the spirited discussion last time (dang it!), please share as to why you're making these out of alloy rather than steel. We addressed this problem 30 years ago with steel pins that we peened over and I still have customer cars out there with this fix.

    BTW: I think you were simply a victim of Peter's over-enthusiastic deputized moderator stage in life. For a while there threads would get closed/censored if there was the slightest sign of conflict. Fortunately things have vastly improved. Thank you Peter.

    Hello Frank,

    Simple really, my friend the toolmaker works for a company that makes bespoke components for F1 and other racers - and they often have small offcuts of this very strong, and expensive alloy. They are too small to use on other components usually and he just uses them up doing this. Easier to machine than steel and just as strong. I shared with him my need for a replacement pivot pins on my last restoration when he was visiting and he said "I can make you some of those" ...... and he did. So here we are. All the proceeds go to him not me.
