fiftyv8 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.

fiftyv8 Well guys, I am back and getting into it.
It has been a tough time but I am over it for now and ready to make some progress.

After numerous attempts to get a hinge location relating to the firewall and have a clear lift, it seems I have not been successful.
In the meantime, I have come down with a case of Chronic Fatigue Syndrome CFS which has been no fun and taken away most of my project motivation.

However, I can now see the light at the end of the tunnel with this CFS.
It has been a challenge to say the least, but have been looking a round the forum on good days.

The good news is that I have also spent my time wisely and discovered a different style hinge which I decided to try after many mock ups of the original hinge I made with no success.

When I say no success, I really mean not enough improvement for it to work without scraping or binding.
The alternative hinge I plan to use was discovered quite by accident and had been under my arm all this time as it is being used in a console to the side of my TV chair. I rarely open it but was looking for the lost remote controller and opened the lid and the penny dropped.

I thought that discovery was going to be too easy, if it worked.
I took the pair off my console much to my wife's disgust and installed them and made new mounting brackets.
I could not be that lucky of course as they did not work either, but I could see their potential and have started modifying them to see if I could get them to move slightly differently and that is where I am right now.
If this fails I will definitely walk away from the idea of a firewall hinge.

Stay posted...

fiftyv8 To all the Forum members who care to take an interest in my project work, may I wish you all a very Merry Christmas and a Happy New Year.
I've remained off the radar as I have been diagnosed with Chronic Fatigue Syndrome which has been quite debilitating to say the least.
It came on after my bout of Bronchitis.
I am determined to beat it and get back to my old self asap...

fiftyv8 Sorry for no updates, but I've been off the radar with a really bad bout of Bronchitis.
It has taken some time to get over, although I am still not fully recovered yet, hence nothing much has happened other than my new Tesla electric home storage battery was delivered yesterday and installed into position.
It is still to be wired in and commissioned which is still about 10 days away.

I've been waiting for this delivery for about 8 weeks or more and I live in the hope that once operational, it will come close to eliminating my power needs from the grid.
Once it is up and running I will post my thoughts about how it is performing...

fiftyv8 Well folks, its been a while.
Between life, a spell of hot weather and a lack of motivation, I have now got a new idea and have started implementing it.

Well, 2 ideas actually;

1st is a slightly modified hinge design, nothing drastic, but it appears that it may offer some extra lift at the rear.

2nd I have decided to do a mock up on my old wooden engine bay buck and use it to make any hinge position tweaks.

Attached are a couple of pic's of the hinges in place as per the real engine bay, with the exception, I have moved the hinges in from the outer edge by 1" and raised them 3/8".

I can not give a detail explanation for this move, other than to say I am going with my gut right now.

Fingers crossed again...

fiftyv8 I note that many vehicles of the 1940's and 50's with high arched hoods had a kind of V shape or taper to the center along the back edge of their hoods, probably as a means of avoiding exactly what I am experiencing now.

I've have decided to take a day or two off and do some gardening instead and mix with non car friends as a means of clearing my head for now...

idrivejunk "Skid Wedge"! Thank you.

If a nylon washer makes it OK for now, let it. Sidestep that and go to another thing. When you come back to hood hinges later, it will look better and you may see then that you pretty much have it nailed now anyway. I get the same way, believe me. Many times now. Always looks better after disengaging focus from "the thing" whatever it may be, for a spell. Kick it into neutral and just roll.

Well men, I think I am all tweaked out.
My latest hinge pocket tweaking has gone some way to improving the lift motion.
It is more obvious now that the peak of the hood arc at the cowl end is the issue.
As the hood rotates up the arc is moving from the horizonal more into the vertical plane and hence needs space towards the windshield end.

It is so damn close now that if I put a nylon washer in its travel path is rides on the washer and then clears.
The washer is protecting paint scratching for now.
idrivejunk from this Forum had earlier suggested a small nylon wheel or skid wedge for that edge of the hood.
It did not make much sense to me then, but now it does.

I need more thinking time as this is turning into brain surgery...
I really don't have anything in the actual hinge or hood left to tweak now.
I think if the straight seal lip in the cowl/firewall sheet metal had a curve or bow in it at about the center line of the hood instead of being straight, it probably would saved my bacon and cleared.

Pre-load is definitely a part solution that I at this late stage will not be able to take advantage of.
It sure is something to consider for others following in my foot steps.

fiftyv8 Hinges can really do your head in once you really get into them.
I will persist for now, but do have a plan B, which is to use another hinge design (drawings) which I purchased from a guy in Canada for little money.
Only problem IMHO is that it does not look pretty as it has super lift and sticks up oddly when open.
Looks kinder fragile, like a scissor lift effect or could from the look of it end up with the problem at the front rather than the rear......
Plan C is to scrap the hinge and just tie down the hood and make it hand removeable which really goes against the grain in my book...
I am not all that competitive, but I hate being beaten when I am so close to the finish line.

fiftyv8 idrivejunk, I think you are on to something with your comments.
I am gpoing to take a closer look at what you suggest when I get the courage to face it again.

I have been drawn to a similar conclusion with intent of lifting the hinge arms out of the rest position slightly, so the forward movement commences immediately.
Right now, there is a kind of dead spot it seems just for a couple of millimetres of initial movement where the hinge seems to be in limbo so to speak as it commences its path of movement and rides too low to clear the firewall lip edge.

I had to walk away and I am a pretty patient individual, but I needed to avoid being drawn in by the problem and grasping at straws which could have lead me to do some dumb stuff.
So I am now in a cooling off period just mulling over my next steps and listening to others view points.
I am just so close, but finding the tweak that will get me over the line is killing me right now...

Thanks for your continued interest.

idrivejunk Like if there was a roller in the firewall jamb here. Or a plastic nub with a plastic rub strip inside the hood. The rollers or blocks would not have to be embedded in the jamb necessarily.

idrivejunk Would you believe I left something out?

You know what suicide locks are. Imagine some with roller tips. (Heck, weld a roller lifter to the end of the rod and sink it into tubing in the body) So you pull your latch, hood pops ajar. Now you extend the rollers with the suicide lock mechanism, lock, and open hood. To close, set it down on the rollers, retract rollers, push down to latch.

Just another germ.

I attached the inner panel the hinge pockets and then to the hinges and tried lifting it.
Well, it just touches my firewall lip at the rear and wants to take paint off.

Disappointing to say the least.
I know I am real close, so I added a washer spacer between the hinge and the pocket and it kinder clears but not what I was hoping for.

I have now removed the hood from the hinges and cut the pockets out in the hope that I can do some tweaking and get the clearance I need.
Boy, it is close but no cigar just yet...

I am going to persist for now and give it my best shot since it seems so near, but otherwise I am at somewhat of a loss to know what else to do.
Obviously my rejig of the hinges was a get success and I almost hit the target with the mods.

More to follow when I cool down...
Sounds to me like you are close enough that your mind may pop out a solution at any time. Let it stew for a spell and you'll think of something to try. Allow me to strike the flint in your direction a couple more times and see if any sparks fly.

Since I last visited this conversation, I have had some additional thoughts. One about the other guy's Plymouth but another which, crazy as it may sound, might be a seed. Relies again on a tad of hood flexibility. I will drop what I have now...

What if, at the place it rubs the firewall upon opening, there was a little, perhaps spring loaded, plastic roller wheel at the contact point? Could it ramp the hood over that spot without hurting it? Could roller theory be applied at the front corners of the Plymouth with the long hood sides? My vision has the roller(s) completely hidden with panels shut.

Variant of idea seed: Use shaped nylon blocks attached to both panels as sliding ramps instead of rollers.

Bonus thought about corners:

Could there be downward, angled spikes at hood corners that engage cones in the body... that would rest with panels closed normally but as soon as the hinge begins to open, the spike and cone rigs would flex the hood corners out just enough to clear and for just enough of the travel?

Any ponder fodder in that? Can sketch or further develop or debunk the theories.
