Just noticing there is not much support for hinges for the 48-52 Ford F1 hinges.

Anyone ever modify a set of bronco hinges to work on the F1?

Those don't look any different than my 48 F1 (actually an F5, but same difference) hinges do. How much more stout are they? They aren't countersunk for the pan head 5/16-24 bolts, but that is easily remedied.

I know the 48-52, the lower hinges are a bit shorter on the body mounting face than the bronco hinges.(Upper and lower mounts on the F1 series are different lengths from upper to lower on the face where they mount to the body) They appear form the pics to be quite a bit mote stout. But I was looking into them because you can still get them (my 49 hinges look like they have been drilled more than once and are terribly oblong)...

Yes, countersinking the existing holes, or trimming them down and making new holes would not be that bad
 
How are your backing plates? Are the threads all fubar'd are do they look good? I'm about ready to go suicide hinges on my build. When I cut my hinges off, I could potentially make a new set for you.

Can you get the pin to come out between the door side and sill side hinge plates?

I had to drill the body mount side out, but I got the pivot pins out on the driver's side they were bolts, one came out, the other had to drill.
I've got the capability to make hinges, I just didn't want to if I could modify something else to work :) I do appreciate the offer!

I'll probably be making new backing plates.. and I have been looking at whether or not I want to do suicide doors, and fab up my own hinges...

Side note, what does your door opening measure from front to back where the straight portion of the door is? Since I never had a good floor, I just had to take an educated guess that it is somewhere around 36 1/4 or just under that... After welding in one of the braces this morning..
 
Can you post a pic of the exact measurement you want? I'll grab it as soon as I know specifically where you want me to measure.

I've been eyein these hinges for a while. I have a different idea of how I will make them and attach them, but I like the look.

I'll try to get a pic tomorrow night when I get home, just the measurement of what the over all door opening is, as in door width plus door gap to panel.

Those are interesting hinges, I will have to look at that thread, I assume there is extensive bracing on the inside to support the weight of the doors, as they are actually fairly heavy, I was surprised, with no door glass how heavy they were.
 
After looking at that, I rather like the idea of external hinges... however, there would have to be some planning for the bracing on the inside mount... something about sagging doors just ****es me off! HA.
 
I know!!! Bout damn near took my arm off the first time I unbolted them.

There isn't any pics in that thread about bracing inside, but there are lot's of options to really beef it up. I'm thinking about cutting the B-Pillar down pretty good and slipping some 2x2 or so sq tube with a heavy wall, like 1/4" or so behind the B-Pillar skin. I would drill and tap the brackets and then make corresponding holes through that sq tube to bolt through. Hard to desrcibe. If you're not in a huge hurry, I plan to do this later in the week. I'll get some good pics.

My doors aren't hung right now so I can't get you gap measurments. However, where the floor meets the A and B Pillar, I'm right about 34 1/4". We're way off if we are measuring the same thing. Get a pic up tomorrow and I'll double check against what you're doing.
 
I'm in no hurry at all, I have a lot of floor to repair and strengthen prior to starting my chop.
Maybe my memory is failing me, but the door skins I thought were about 35 13/16 wide...
I'll get a pic up tomorrow... I was bracing the door opening with 1" sq tubing to set the opening for about 3/16-1/4" door gap on either side so about 36 1/4"...

I'm using 2x3" tubing about 10" from the bottom of the A pillar up to rebuild what I am missing. I was thinking some thin C channel welded in, and then a mount plate something like the regular hinge mounts that allow adjust-ability... That would work pretty well for the outer hinges..

Single Interlocked links of a chain would be pretty sweet too with a pin through them...
I remember why I love this forum so much, motivation, inspiration, and great ideas and people in many stages of their build!
 
Yeah, I was measuring inside between the pillars, not out side for the door skin to fit in. I'll redo tomorrow and let you know.

I got it in my head for the internal part of the bracketry. I just need to get to the shop and jump on my trusty Bridgeport to put it into model. I'm also gonna give my CNC plasma table a real workout and see if she'll burn some 1" plate... [ddd I'd really like to make sure all of the external hinges have the same radius and what not.
 
If you have something in mind, I can probably have a couple one off pieces cut on a laser machine here. just not sure how quickly I can have it done as they are always busy...

I'll be looking into it more this week as well, probably wednesday/thursday will be garage nights.
 
I already started on my prototype set. I appreciate the offer on the laser table, but I have a CNC Plasma as well as a full machine shop full of equipment.
 
I'm getting right about 36 1/16" on the door opening and right around 35 3/4" on the door itself. The door gap is pretty tight on this sucker.

Ain't havin a shop full of equipment (Even if I can't run all of it, that Bullard trips me out. :p) great?

Yea, that about what my doors are setup for, 3/16 gap.
And yea it is awesome having access to awesome equipment when needed =)
