    It has been a while since I last updated. I have been making the most of the good weather here. Shed/workshop/office build is coming along nicely. One day soon I'll have a place to work on my car..

    Here is version one of the mech:

    All of the apertures line up to the frame, so no changes to make there. What I'm not happy about however is that it does not sit flat in the middle, see here:

    and here:

    At first glance it would appear that I've made the circuit too long. Actually it is exactly the same as the original. It too sits up in the middle:

    So while I do like to copy the original as closely as possible I really don't like how it sits up, so I've cut 2mm(almost 0.1") out of the centre. Version 2 of the mech has been ordered.

    Here is the new artwork:

    I'm still working out how to attach the battery snaps. This has been a challenge. The latest idea is to rivet them but because the circuit base material is so thin and I cannot source any suitable washers I'm having a back up plate made up. This plate will go on the back of the circuit to strength it where the rivets go through. I'm having it made from 0.6mm(0.023") thick fibreglass.

    It will mount like this:

    I should have the version 2 mech in about week. If that fits well I'll go ahead with the first run of 10 units.

    Looks as good as the original fit , Although i know you want it to be flat in the center area ,
    if the original lays the same , I do not expect any problems with it , rivet area should be good with extra enforcement, Did you get the snaps all figured out ,
    I LIKE IT Andy :):):):)

    I'm now happy with the riveting. A friend has machined some tooling for me:

    The one on the right on this picture has been done with the new tooling. Actually I went a bit far in this example(hit too hard):
    [​IMG]

    I received version two of the mech and I'm still not completely happy with the fit. I'm not sure how it is for you guys in the 'States but for my Australian Ford there has been a history if ill fitting and poor quality reproduction parts. I'm trying to make this the best I possibly can.

    So I chopped up the mech into 4 pieces and placed it on the frame, joined it with sticky tape, scanned it and modified the artwork.

    I will order a 3rd mech. Probably don't need to but I would rather not risk ordering a batch of circuits that are not quite right. So when I receive the 3rd mech I'll test fit it and if that is right I'll order the first run of 10 circuits.

    Here is the chopped up version 2 mech on the frame. I have blacked all the edges so that I get a hard edge when scanning it:

    Here is the scan:

    And the modified artwork. Can you 'spot the changes' LOL?

    If you are going to sell them here, you should consider deleting the Ford logo.
    They have even shut down forums like this one for copyright issues.
