    Roof Hinge Assembly Measurements and comparisons inc Stainless

    I've been measuring various hinge assembly parts and have scribbled my measurements onto the original drawings that have been posted elsewhere.
    I'm wondering if anyone can draw these up 'technically'... I'm slightly frustrated in that none of these measurements are taken for each part from a single ref point; everything is measured from different edges etc. I have marked as many measurements as I can, and when adding up some of the distances, they do add up to be up to a couple of mm out overall - one of the problems of trying to measure from 'bends' etc.
    I take no responsibility for any of these being wrong of course `¬)

    I have acquired a second 'old' set, which I'm not sure if they are from a MkI, as they do not have the ram lower mounting point (and a shorter 'side plate'), but they could also be something that someone knocked together themselves of course!

    The ones marked as MkII are the original Elam's hinges as fitted to my car when bought.

    I am also going to post a few photos that illustrate some of the anomalies on the roof and body mounting points that I have (probably tomorrow now, as there are several) and would appreciate any feedback on anything other people have found when mounting various hinge assemblies.

    For now though, these are my measurements and the photos of the parts I have...

    The stainless set (unfortunately end on arms not welded square, as well as bracket holes not drilled square to brackets, so they need either replacing or re-jigging slightly - this does not affect the dimensions tho...)

    I will post here some pics of the body and roof mounting points tomorrow to highlight some issues, but this should be a good start?

    HELP; how do you post images; I've had to post links to photobucket above for the photos, as they are bigger than the width of the window... shouldn't they autosize?
    How do people post smaller picks that open in the picture viewer with 'next' etc that I've seen in other posts?
    It would be nice if I could actuall see the photos above, rather than the links... It worked for the drawings as they are smaller than the photos...?

    To post images how you say you need to add them as attachments on to your post, then you will get the small thumbnail that you can click to open the large version.

    Sorry...I misunderstood in the reply to the PM!

    ahh! Thanks, that's through the 'manage attachments'; so the max size is 620 width?

    Thanks `¬) I'll give it a go tomorrow!

    Thanks Martin, some nice shots showing the details of Superman of Steels hinge design. They are very well made, its a shame that yours are all out of square.

    I think we have more than enough takers to do a bulk order IF we can find an engineering shop to produce to the same design / spec, but straight!

    There are a couple of issues, one which I've noted on the size of the stainless plate being larger and catching the curve of the main body; not sure if that would be an issue for everyone, but think they could be made slightly smaller just in case.

    It would be nice if anyone else could confirm any measurements and properly cad these up to check my measurements tally - I was surprised that the angle of the roof bracket seemed to be 15deg rather than the 10deg on the original drawing?

    I will post some photo's showing some of the issues mounting the brackets to the roof and body, particularly if other people have had similar issues, but I'm at work now and haven't had the chance to upload them to photobucket yet! Again, it may affect the final dimensions to make fitting easier.

    Cheers

    I can BUT only next month when I make it back to the UK.. I just wish I had the CAD skills (I don't), but I'm tempted to do a course on this as there have been some many occasions recently when having them would have helped a lot.

    Martin,

    Where did you get those original drawings you annotated ?

    Here is a start Ill put the dims on and send Dan the PDF file to put in the download section then they will be to scale.
    Martin you have the bush inside the oilite bush as 37.5mm is this right?

    @Gmacz; that's what I did too, but when I went 'preview post' it had extended the image off the rhs such that the right most bracket wasn't visible; most curious!

    @islandman; http://www.euro-nova.co.uk/vb/showth...mensions-in-mm which was linked to from http://www.euro-nova.co.uk/vb/showth...l=1#post119271

    @Dirk; That's what I had - I only checked one of them. There is a bit of variation between the arm ends that the oilite bushes fit into, but say 31.6 to 32mm, + the 2*2.72mm of the lips on the bushes, which gives 37.04 to 37.44mm, and the steel bush inside is fractionally bigger; so 37.5mm on the one I measured.
    The lips on the oilite bushes had been filed down not particularly well on some of the bushes, but the iolite bushes seem to be a press fit into the tubes at the end of the arms, and the inner steel bush is a looser fit inside the iolite bushes, such that it rotates easily.
    The ends then fit inside the 38mm width of the body and roof bracket. `¬)
