    Building up the nose cone is turning into quite an epic task.

    I have made and welded in the 1st section for bottom together with the radiator mounts, and now as it’s a stable section I have screwed all the panels together to trail fit.

    Just as well, it all screwed together quite well, and with a mixture of original BMW parts and repro parts there was no need of a tapping stick to re align the panels.

    With it all screwed together I can now make a template of the last section that strengthens the bottom panel that welds to the new section I have made. I have no clue as to what this panel is called, maybe its called –the radiator scuttle lower reinforcement support section?????

    I think I’m only a few nights from completing the nose now!

    Yesterday my pressing parts turned up for the bonnet shut panel (again I don’t know what its really called)

    All made out of 5mm steel and cut out to the same sizes as the original apertures give or take a few mm! these should make the repair panels look a bit more factory!

    I could have used a hammer and dolly to do it but wanted to have a go this way, as its a bit more fun trying stuff out.

    Surprisingly they did not cost that much – found a local company who does this a lot, and they CAD it out and cut them out for me for a small fee.

    After plug welding on the base plates to the male sections ( I did this to stop the thin steel from warping), my method of compresing the shapes into the panels was to simply use 4 bolts aligned through and an impact gun to clamp the upper and lower plates.

    The results (I forgot to take picture but will tonight) are really good, so it was a worthwhile exercise – I could now go into production with this tooling!

    I have finally started fitting the two ends into the existing bonnet shut panel.

    There is quite a bit of curve shape needed to match to the existing panel, and I have managed to get it something like using the planishing hammer, but still needs a bit more work.

    Screwed the two repair ends temporarily in place So I could build up the whole of the nose cone to check it all goes together!

    With the grill/ light front panel screwed in place, this now gives me something to follow with regards to the bonnet shut panel as the middle section (well all of it really) was so rotted out.

    Now I have something clear to follow, and can start making and pressing out panels for that section next week

    The good news so far is, all the parts are slotting together very well and only small adjustments are required.

    I will not be welding the valance and the front grill/light surround to the nose until I start building the car up – but will leave then screwed in place just to give it a bit of strength.

    Old and new - In some places I have been a little bit over zealous with the grinder and gouged the steel – but my painter can deal with at as I can’t be bothered to make some more end panels – there has been quite a lot of processes to make them and am not in any mood to start over again.

    If you look at the front of the panel - you will see that I have nothing to follow! - so had to build up the whole section .

    All screwed together - not for the first time!

    The last week or so I’ve been trial fitting the two inner wings.

    I have been lucky and managed to buy an old new stock RHS inner wing (a beige paint) that was made in 1982.

    The LHS was still available direct from BMW. (black paint)

    First, I must point out that the construction of the old 1982 inner wing is of a much better pressing.

    When offered up, the old new stock simply dropped into place and only needed a little tweaking.

    The new part took a good few nights of tweaking to get into the right place, I had to take a few breaks as I was ready to smash it up into little bits…….

    To get the inner wings into the correct place I marked the dimensions (taken from the work shop manual) on a steel plate and mounted it level to the bottom of the front crossmember mounts.

    I also quickly made up a blank with a small hole drilled into the centre to be bolted into the top of the suspension strut, the small hole is for dropping a plumb line through.

    Looking at the pictures below you can see I have used my digital inclinometer (a great thing to have) to get the car level (I could not get better than 0.02 of a degree!).

    The plum line from the top centre of strut is now within a mm of the line scribed into the steel plate, and that according to the workshop manual is within tolerance, the distance to the top of the suspension turret is 0.557mm, the correct dimension should be 0.558 plus or minus 2mm and that is in tolerance.

    Now it’s pretty much fitted and I will screw it on temporarily, as I bet when I fit the nose cone it will throw everything off!

    Made a few bits as well for the nose cone – 2 mounting brackets

    Morning Marc

    I'm sure I would have no idea how to do what you do.
    Very impressive and inspirational work indeed.
    Whatever the problem you find a solution - hats off to you!!!
