    I don’t think using these wires as laminates
    was common so this may not be of much
    value other than to show the versatility of
    these OMC coils as a really inexpensive
    ($.00 in this case as they test good and the
    Yankee in me can’t through them out)
    substitute for earlier coils that have gone
    bad and are no longer available.

    I did a double OMC coil swap on a Caille, but had to reverse the orientation of the coils so the high tension aligned with the holes. When you do that, you must reverse the polarity of the primary wiring.

    Wonderful tutorial! It is problem solving like what you displayed that makes our club such a valuable asset to the membership!

    Its been explained to me that there is so much
    changing when doing these modifications
    there is really no way of telling other than to
    watch the points to see if they are pitting and
    which direction its going. I have no
    understanding of what is taking place here but
    my source of knowledge who I value says that
    even the length of wire your adding to the coil
    effected the condenser value that would be best.
    The condenser here tested good so I used it. If
    it was bad I would have used a NAPA (Echlin)
    AL869. Its what I have used when doing this
    conversion in at least 6 different model motors
    using these coils as well other conversions using
    different coils from 1910 to 1947 and with good
    results. Even when these old motors get used a lot
    its not like something that get used daily so its
    going to take awhile to see if there is a problem
    even if your really off. (As it has been explained
    to me.)

    May seem insulting but don’t take it that way, Use the prick punch then use a center drill, this will start the hole where you want it, then you are left up to how sharp and how properly the drill is sharpened to determine if the hole will drill straight thru …or not… also use of a good cutting oil will also aid in your endeavors.
    I was taught, many years ago, when hand drilling holes in a drill press to prick punch, then spin the center drill backwards by hand to get it as close as possible before turning the machine on to have the center drill cut. Should get you within .005

    I did exactly that and bit was new.
    Drill bit would always move off center to start.
    Issue is likely worn out table top drill press.
    Did you get the reply to your want add I sent
    this morning?

    Does it spark?The reason I ask is,I have been trying to get spark on a conversion like yours with little success.The only difference is that my mag plate is the one with cast in shoes.

    I haven’t tried to start it yet but it
    does spark. Do you have both
    coils facing the same direction?

    Yes they must face the same direction

    Yes they are new coils installed just like those in picture.Only difference is I didn’t “insulate” the bundle of rods as you did.I’m going to give that a try.I do get a very weak spark,(enough to spark a plug) but not enough to even jump 1/8 gap.

    I don’t know that mine will jump 1/8″
    I not sure what the gap of the plugs
    were when I tested mine but initially
    it wouldn’t fire them till I cleaned
    them. Might be why this rods instead
    of laments was short lived. I turned
    the motor over with a drill and its
    somewhat slower than what I could
    pull it over and I got a constant spark
    at what ever the plugs were gaped at.
    Snow is keeping me out of the shop
    just now. Sending you a PM.
