I think that I have become a little lazy during this current lock down and my old age.
I have spent quite a bit of time fooling around with the sheet metal portion of my hood project with little to show for it.
I have removed all the surface rust from both sides of the inner and spent much time test fitting the inner and outer skins to a point where I am happy with the fit. I have tried to ensure that one skin is not stressing the other and the fix is more a naturally compatible.
I have gone over the inner and tried to remove or should I say reduce the number of highs and lows in the sheet metal.
Since the outer face of the inner sheet is not seen, I have basically ensure it is flat or with only lows that I can fill with body filler.
Body filler is a necessary evil IMHO and I always aim to use the minimal amount.
While the outer surface of the inner skin has been primed and painted roughly with some old spray can paint I have no further use for and decided to use it up as a rust preventative.
The inner face of the inner skin is coming along nicely, considering my skill level and next week I hope to be ready to purchase some spray on primer high fill that will hopefully remove most of the minor scores and marks in preparation for further work later.
Next steps will be to cut the air cleaner opening in the outer skin and press the lip into it and the do some more body filler work in readiness for the mating of the two skins to make the hood.

The bonus I take away from using these TV chair hinges is that now my hood opens up to 90 degrees and the tail end rests on the radiator support rods.
This is extraordinary when compared with my first hinge design where I was struggling to get a 35 degree opening and at one point it was even smaller and hardly worth the effort.

Thanks RIP, my hinge is not a perfect solution, but the best I can come up with to handle the criteria of the problem.
It is easily removable should I choose to run without a hood.
I never heard the end of it from the cook regarding the borrowed hinges from our TV chair console.
So rather than fighting it, I reinstalled them and all is peaceful again...
Much work still to be done in small steps so no errors are made.

That hinge looks pretty good. It is nice and simple and non cluttered...
By the way Mate did ya ever replace the hinges on the table that provided your insight to this success?
Looks good keep plugging away.

Well, I now have my new stainless steel laser cut hinge components and I have assembled them.
I still have some finish welding to do but for the sake of showing them here is what we have.
One pic is of the prototype and the other of the stainless hinge.
I am now in the process of trying to get the inner and outer skins to match up ready for attaching them to form one unit.

Dear friends and fellow Forum members interested in my project pursuits, I am sorry for the delays in posting progress, but progress has been slow.
I do have some more material to post soon, I am held up again by my laser cutting guy as you may recall this happened previously.
Any way stay posted as I will have fresh up to date pic's very soon.
In the meantime, as you may be aware I have a number of YouTube videos listed and some of which have been well accepted.
I do not derive any payment or income from these, but do like to see them front and center so that they are easily accessed by interested folks.
If you care to see what I am talking about you can just GOOGLE the following. Cadflat Video Series
Once there, you can click on any of the 5 videos I have up loaded and I would ask that you kindly hit the SUBCRIBE button on one or all of them.
By subscribing it helps keep these videos front and center which from my point of view would be very helpful to the cause.
If you do feel inclined to support this request, then I thank you very much indeed.
Your support is what provides me with the motivation to keep finding topics of interest to post...

Well my friends, I am pleased to report that the new hinge works and the hood clears, so let the party begin...
I am totally over the moon with this result.
So high 5's all round I guess.
There is still a lot of fiddly work ahead, but it kinder means more now, that I know it will work and anything I do now will be worth the effort.
I guess the hinge pic and its mounting is self explanatory for you.
It is odd but it works and not as pretty as my first choice.
Pretty is a bit like BS, it only gets you so far...

Just for the sake of the record, attached is a pic of my final cardboard pivot points.
You will note;
Blue A - is the marked trajectories at various stages of movement. Important to success of this hinge was to keep the left hand end of the hood attachment point lifting and rising to clear the firewall edge. So too much lift at the RHS would cause the LHS tail edge to drag on the firewall.
Green B - are the new chosen pivot point when compared to the original hinge.
Pink C - are the location of the original hinge pivot points.
Orange D - is the perimeter shape of the original hinge base plate.
Yellow E - indicates a larger base plate size is required to the modified hinge for attaching one of the new pivot points.
Purple F - is a hole in the cardboard used to place a pencil lead into and scribe the arc of each selection of pivot points.
So the original hinge arc was scribed first as the base which I knew was not workable and then each additional point was scribe to compare any improvement against the original arc and that of its trajectories.

Sir you are a glutton for punishment!!
Stick with it and you will be successful!

Thanks, yes, I have done all the footwork in checking out hinges.
I did purchase a pair of cabinet hinges with springs but the also we not capable of the swing I needed.
I am onto it now I believe and hope to be able to declare a EUREKA moment very soon.
Besides the hinge working the way I need it, I have space issues.
I have failed myself by not considering a hood earlier whereby I could have much more easily accommodated my firewall needs with welded in pockets or similar.

I have now made a card board mock up of the basic hinge principle and allowed extra length of arms and the option to re-position pivot points.
As you can see by the number of puncture points in the card board I have just about turned it into Swiss cheese. :lol:
Each time I felt that the pivot points were close to what I sought, I graphed the swing and marked hood angle at specific points.
I have now chosen what I feel is the best possible scenario of pivot points and arm lengths.
Next step is to replicate them in steel and mount them onto the car and see once the hood is attached whether it really does clear and work as anticipated

I have started moving forward once more with this hood project and decided to make new hinge pockets which have been welded in, plus set the front lock down pin mechanism in place to set the position of the hood with respect to the engine bay opening.
So far so good and then I will fabricate my modified hinges out of mild steel (prototype) that look to be capable of clearing my firewall.
One needs the patience of Solomon on this project.

The above picture is the hinge I plan to use/modify now.
Since it had no brand name etc on it, I thought I'd never find any information about it.
However the power of the internet and the right choice of search words finally provided me with this picture which is identical to what I had in my console.
I still don't know who makes them or where they are made, but I did end finding a supplier/agent who has them in stock.
They are mainly used in caravans and RV's as a hinge for a bench seat that has a lift up lid that has a storage compartment below it.
No need buy a pair for now until I am sure they will or wont work as required.
