    Shweet Plaka. I want to pull mine off the bars, anyway, to repair someone's attempt at no running headlight. D'oh. I'm also going to have to invest in one of those lighted knitting magnifying lights for my buddy's garage. :rofl

    So far I've drilled the shiftless locking fuel cap to remove it and repaired the rear brake level sensor. Think there's any interest in pics?

    Plaka,

    If you have even some of the spring left you can make a replica.
    I used to have to make springs for pocket watch lids when I was making a living as a Jeweler.
    You can buy spring wire, all you need is the diameter of the wire and the length.
    To make your own spring get the correct wire size and find a piece of round stock that is the same OD as the springs ID.
    Cross drill a hole for the spring wire and insert the wire.
    Now wrap the wire around the rod keep it tight by holding it tight against a piece of hardwood while spinning it.
    I used my Flexshaft to spin it but a dremel or drill will work.
    Make the spring longer than you need it to be, i.e. more windings, stretch it to match the original and cut it off.

    (just found this site while looking for a wire source: http://home.earthlink.net/~bazillion/matls.html )

    I had an interesting scar on one arm for several years. It was a series of very fine, closely spaced parrallel lines running across the arm and extending towards the wrist.

    I was winding a spring on a lathe. It was maybe 3/4" diameter and fairly stiff wire. I'd made an undersized mandrel to account for the spring relaxing after the wind. I had the lathe turning with my mandrel in place and was feeding the wire off a hand held spool. The length got right so I shut off the lathe and with the other hand I cut the wire leaving a long tail which was later to be fashioned into a hook. Dumb move. As the spring relaxed the wire whipped around a dozen times in an instant, cutting my arm every turn. I was plenty pissed off.



    The spring I need is very small, very fine wire. It's also oversquare, short and fat. I'm going to try punching a disk out of the wall of some silicone tubing with a belt punch. If I get the right size it should work, and won't rust.

    The neutral switch connectors are a real PITA to plug in once the transmission is in place. I managed to get the connectors back onto the neutral switch the first time I had the trans out during restoration...

    but no such luck today. I had the trans in and struggled to get the connectors onto the neutral switch...

    wouldn't ya know it, S N A P the connector breaks off from the switch.

    Pull the trans back out, install new $35 neutral switch, build sub-harness so I can plug the wires onto the switch while it's still on the bench, modify the BMW harness to fit the new sub-harness, re-install trans.

    Bummer!

    So, you've lost a turn signal lens screw and you local BMW dealer tells you they are no longer available...

    You start with the local hardware store, move up to the specialty hardware suppliers (Hillco for example), but no joy on a M3.5 "fine thread" x 25mm machine screw.

    Next you turn to the web, and you find several sources but they want $3 / screw + shipping, Sheesh Boo Boo.

    Put on your thinking caps... who might have a M3.5 fine x 25 machine screw!?

    Dubro to the rescue! Yes, Dubro part #2274 is what the Dr. ordered. You get four (4) screws for under $2.00 (you do the math ;-)

    Sure, purists won't like the fact that the Dubro screw is an Alan head and black oxide, too bad, go ahead and spend your money on those $3 + shipping screws and have a nice day.

    Oh, ya, and if you're looking for a substitute for the BMW washer for the turn signal lens screw, this Honda part fit's perfectly.

    Or you could convert to M4 x .7 and have your choice of nice stainless screws for cheap.

    BTW, I did a thread on rust treatments for screws. That black oxide doesn't last long, and then looks like hell. Baked on Linseed oil over the black oxide looks just as black and seems to be extremely durable. Touch up the oil inside the hole after installation and just let it dry.

    I went to my local Tru-Value Hardware store and bought the proper size Stainless steel screw, but the head was too big. No big thing, I ground the sides of the head down carefully on my bench grinder until it fit. The screw was $.57 it took about 1/2 hour of slow careful grinding. The satisfaction was priceless.

    So it is Saturday afternoon and I find that the two male one female adapter on my coil has bitten the dust leading to no spark. Local BMW dealership is closed. What to do?

    Tried two auto parts stores but the have nothing but crimp wire connectors. Leave last car parts store and think. Then it comes to me. Off I go to the mall and the closest Radio Shack.

    Walk in and tell the 16 year old what I need. "I don't think we have that", but he asks the 18 year old who says the same thing. I ask to see the bin anyway. Inside said bin is #6403064 an 8 pack of "Quick Disconnects Adapter Set". Huh the kid says, "That must be new." Right.

    $2.67 I was out the door and I now have seven extras. There are three different types the original "angled" type, but I switched up to the female with the two males side by side which I installed pointing downwards.

    I'll turn the heads down for anyone who wants to send me the screws and a SASE.

    Got a lathe that will make short work of it.

    Thank You. I will need to do mine in the next year and may well look you up.

    I was also asking in the generic sense. I got the bearing puller for my rear wheel from the local auto store on a free loan. How often do I pull bearings? Not enough to buy a nice, and expensive tool like that. Wonder of there is a front range or NoCo tool pool?

    No. They cost you $1.05 per screw for the 8 you need. As you sell screws for $2.00 a set your price will go down till yours are free after 4.2 sets sold. Then you are into making profit. Make sure you report this income to the IRS unless you are going to declare yourself a non-profit. :lol3
