I thought since I was doing headlight, might as well do the 1926, I'll add 1927 when I get it done. I would really like some info on those gas lights. Don't know what's in them and I think they'd be fun to draw too.
I think this is pretty much correct, my friend George Clipner sent me some photos of both 26 and 27 showing the differences, he's got a 26 touring. But if you think there is something I forgot or needs to be on here, please let me know.
Damn, I should've caught this...Model T Haven has a different part number for these buckets.
One thing I'm wondering...is there a right hand and left hand of these? It would make sense otherwise on one side the focusing screw will be in the 9 o'clock position whilst on the other side it'll be at the 12 o'clock position.
Martin, there are lefts and rights, but curiously it is not the focus screw hole that determines it. Before I tell you, can anyone guess what differentiates a left 1926 headlight from a right?
By the way, the focus screws are at 6:30 (R) and 10:30 (L) when mounted correctly.
Hole pattern on the mounting foot?
Position of the bucket on the mounting post...slanted in the opposite direction slightly to put the lens in a vertical position?
Following my own observation from the above.
No, although they are often "tweaked" to fit a certain car. Do you give up? If you have a sample and look closely, you should see it.
There's no left or right for 26-27 buckets. If you examine the bucket, there's two weep holes toward the bottom--Oriented on either side of the mount. They're made to mount on either side so that a weep hole will be at the bottom regardless of which side the bucket is mounted. The parts book also indicates a single bucket for left or right mounting.
I can see that for the 27 bucket, they mount on a bar that spans the fenders, but you'd think that there would be some sort of difference between the right and left on a fender mounted bucket.
There is no difference on 27 buckets, true. 26 buckets definitely have a right and left. There is feature that is not symmetrical. Every 26 bucket I've looked at (for this) has had this feature.
From Bruce's Book:
6501AX and 6502AX (Right and Left)
6501CX and 6502CX (Right and Left)
6511NX magneto type, bar mount.
6511MX battery type, bar mount.
The 6501/6502 types were similar in shape to the
1925, but now mounted on posts that in turn mounted
on the fender. The right and left lamps differed
mainly in the positioning of the lens, and could be
interchanged. Later 1926 production lamps (6511
M,N) were mounted on the fender to fender tie rod.
Standard lamps were all black but nickel-plated rims
were optional. Nickel became standard during the....

I don't think the lense position is different. The headlights are somewhat interchangeable, (I've seen cars with two lefts, two rights, and mixed but backwards). The headlights are definitely different (as evidenced by different part numbers) and easy to spot once you know what to look for.
Ok, what would I be looking for? Inquiring minds would like to know, lol .
What is purpose of the #8 washer behind the cotter pin on the focus screw?
Ford script horizontal when mounted correctly?
Martin, do you have an actual bucket in hand? If so I'd like to give you one last try. With your excellent eye I think you'll spot it.
No, Steve. The "Fords" are symmetrical. They are on the LH side of the bracket on both sides (usually).
Tom, no, my car is a 22, I'm doing these from pictures I've gleaned off this site. This site is great for pictures of all sorts of stuff, you should see the load of carburetor pictures I've gotten, if I could get some good cross sections I could draw every one of them too, lol.
The parts book says you rotate the door (and thus the glass) to make a left or right.
The real problem is that the mounting screw has to be positioned horizontal and in line to the sockets for the bulbs to properly focus the two beams. That is only possible, if the mounting bracket is also horizontal.
This was an item for an early service change that never happened.
The problem was soon corrected with a different headlight and a mounting bar, but there was never any recall. The official reason for the change was listed as the police could not see the front plate, so they hung it on that bar for improved visibility.
I have a few 26 buckets out in the shop I just painted for George House. Two are flat-back and one is round-back. I'll go out and shoot a few pictures after dinner and post them about 7;00CDT unless someone beats to it.
There's a couple of versions of both the 26 and 27 buckets. All say they are left OR right.
It should be noted that your drawing titled "1926 Headlight Assembly" should really be titled "Early 1926 Headlight Assembly" and the 1927 drawing should be titled "Later 1926 and 1927 Headlight Assembly"
I'm telling you that there is a physical difference between a L and R 26 bucket. I'm talking bare bucket without the lense. Look closely at George's lights and I think you'll see it.
I don't think that's correct Jim. Or at least the statement needs refinement. Perhaps there's some variations between body styles and/or assembly plants. The early 26 lights mounted directly to the fender with no light bar. The later 26s used a light bar (first version-more like a fender brace) but used the same bucket bolted over the light bar through the fender. Is there a late-late 26 light bar?
I think this could be the ever recurring model year vs. calendar year problem. Or as noted, body style variations.
What am I looking for Tom? I got the buckets loose so I can't be sure of a matched pair from the same car.
Here is what the encyclopedia says for 1926 headlights, "The headlamps were mounted on the fenders in early production, then on a tie bar between the fenders in later production. The tie bar evolved through several modifications in 1926. Earlier designs were just a connecting rod between the fender-mounted headlamps. After a few modifications of the tie-bar, the headlamps were finally mounted on the tie-bar itself, instead of on the fenders."
Everything I've read indicate that the early '26 model headlights had the "duckfoot" mount with no crossbar and the later 26 were mounted on the crossbar like the 27.
That's what I'm saying. Your last sentence contradicts your encyclopedia quote.
Early 26 - Lights on fenders, No "tie bar".
Late 26 - Lights on fenders, With "tie bar".
Later 26 - Lights on light bar. (Stud Mount)
1927 - Lights on light bar. (Stud Mount)
Here's the pictures. Don't mind the dust.
Flat back 26 buckets. (Both the same)
Round back 26 Bucket. Bracket is off set and positioned further back on the bucket. This makes the headlight set forward more than the flat back style.
Ken, can you take a picture from the front of the buckets?
I think we are in agreement. Early 26 is a duck foot style and late 26 is bar mounted. Exactly when they changed over, I don't know.
This also agrees with Langs. They show #6512 bucket as fitting 26 and 27 and mounts on the bar.
As I said, for Martin's drawings to match what really happened and to match what suppliers supply it would make scene to label the drawings as early 26 for the duck foot and late 26 and 27 for the bar mounted.
Round Back - Front View
Flat Back - Front View
I can't tell on the top one, but I'm pretty sure that the bottom one is a RH. Water drain hole goes down.
The two flat back buckets are the same. They have two weep holes. So it could be mounted on either side. I just checked the round back and it doesn't have any holes.
The arrows point to the two holes. You can just barely see them in the spring grove.
Curious. I've never noticed one with two nor one with none since I've been looking. I suppose they may have made some ambidextrous ones from the factory (makes sense) or an extra hole could have been drilled by someone at sometime. Perhaps the no hole one is early, before they discovered a need for a weep hole. Maybe something to check at Benson Ford Research Center if I ever get there.
Both my '26 lamps has two weep holes each. But the spring covers the small holes almost completely, so any excess humidity will have a hard time finding its way out there.
