As I continue on with this project, it has become apparent that it is made up of a number of sub projects besides the main body of the hood.
I see it as being;
• Making the hood
• The cut out and pressing
• The relocation of oil canister and radiator overflow bottle
• Hinges and lock down fabrication
• Paint finish and any other surprises...

I think most projects have sub-projects, or what I usually call "but firsts." I want to do something, but first I have to do this or that.

I agree totally, but this just kind of snuck up on me as I believe I was just too focused on doing the sheet metal and as I quickly got on top of that or so I thought, all these other considerations started to hit me.

The one that I have tried to ignore, but which has become the elephant in the room, is the fact that still after all this other stuff, I need to find a suitable press that is wide enough between the posts to accept my project which at its narrowest point will be approx 36".

That said, I have just realised today, that the pressing area is not in the center of my 36" which now changes everything and without taking any measurements yet, I realise that I am actually looking for a press with an even greater measurement between the posts, which is starting to be of some concern to me, as I can only to expect to have so much luck on my side.

I have discussed this problem with a good buddy of mine, who thinks he still may know where such a press maybe located, otherwise if cornered I will attempt to press this project under the opening of a big brick doorway using a sturdy jack and a post.

I happen to have access to such an opening, but I must give that idea a little more consideration to be sure...

Not much progress to speak of, but oil canister has been relocated.
I moved it up by 1 head stud to bring it inboard.
Some days things just go so right and yet other days you just can't take a trick...
This was a good day.

I actually made a whole new bracket.
I originally had thoughts of modifying or cutting the old bracket, but decided that since I have other similar Cadillac flathead engines that this old bracket may come in handy on another project or help out somebody else later.

You can see the difference in position between the new and old locations.
Who knows, I may even end up with a better gravity oil feed back to the engine since I have increased the head height... :pray:

Sorry about the side ways pic, but I seem to have a problem loading portrait pics always... :violin:

Bad news, while installing the oil bypass canister in its new position I have managed to strip the thread in the block for one of the head bolts. :violin:
I struck a similar problem when rebuilding the engine but that was in the early days and a helicoil was installed to fix it.
Well, I guess now I will be removing that head and installing another helicoil, what a bummer... :(

Too bad. In the last picture you posted we can see how the bolts that secure the bracket for the oil canister, are also the head bolts.

So I guess you have to remove the head of that side completely to gain access to work the helicoil. Sorry for the mishap.

While contemplating my cylinder head repair, I have determined that I would like to use a firewall mounted hinge system to operate my hood.
This means the hood will open like most conventional vehicles.
I have done quite an extensive search of the net to determine that while I now know what kind of hinge I am shooting for, but all or most are too large to fit my application.

Attached are a couple of pic's of what I am looking for.
In fact I have decided to make my own hinge to suit my application, but having never had much to do with hinge design, I seek anybody out there who can tell me in theory how to work out such a mechanism.
Maybe a mechanical engineer or similar on this forum could chime in.

What ever comes of these discussions will be a valuable record for others to learn from into the future...

My hinge will need to mount vertically at the firewall and is able to sit up high close to the hood underside.

You can say that again.
No pressure really, just wanting the option of a decent hood.
Biggest issue is taking care not to scratch paint etc at this late stage.
I found another hinge style that I like, which I will explore further.
Not to buy but to consider the action principle for movement.
It seems that is for an early C10, so if anybody has measurements please offer them up...

I have decided to have one last attempt at working a hinge out from what I know by looking at others for sale.

What I did is take a copy of what I found on the internet and added it to my pic's folder, then resized it to about 1.2 times so the arm lengths are about what will work for my space.

I then printed at the larger size, cut out all the moving components and glued them to some old cardboard.
I needed two copies as cutting out destroyed over lap joints.

Once dry, I cut them out and took a 2nd copy of my pic and laid the cut pieces over the pic and pinned the centers using staples and thumb tacks.

I then took it out to my shop and held it in the rough location and took it thru its movement range and it seems to work pretty good.

I've started roughing out my stainless steel metal components.
Things may slow down a bit now as I am trying to work out what method I will use for the pivot points, rivets or bolts.
I have ordered some sample Chicago nut/bolt combinations to see how they may work.
Part of the problem is the Chicago items require an 8mm diameter hole and since I've scaled the original hinges down in size 8mm is starting to not leave me much metal around the holes.
So that is why I say I have roughed out my metal with an extra width of material to see how things will fit and work.
It is early days so I am not locked in to any one solution just yet.
Fun all the same...

Very clever solution for the hinges. Congratulations on your creativity.

I have one concern. When the hinge operates, it starts displacing a little bit away from the plane where the fixed bracket is at the body. Will the hood be able to clear everything while it opens?

Good question Esteban, truth is I expect it will clear, going from the amount of times I have observed my model, but in reality I am not 100% convinced yet.
Good old Murphy's Law may come into play and haunt me. :o

Being that I have fabricated all the components and to some extent have become the master of my own destiny, I expect that any tweaking required can be dealt with, although I don't want it to be any more difficult than it already is...

Time will tell. :?:
