I think these are self explanatory, they're just the 1926-27 versions.

Martynn: Beautiful work again, thanks for sharing. I reviewed and read comments with the pre '26 drawings you posted. Weren't the pre '26 and later post '26 drive plates and clutch drum bolt connections different? I have a '26 and it is similar to both your pre and post '26 drawings.

There appear to be numbers on the driven gear teeth in that drawing, are they significant? I'd recommend a note pointing to triple gear timing marks.

An isometric view from the drum gear end showing mesh with triple gears and driven gear would be helpful in my opinion.

It would be helpful to show detail of one each of the clutch discs.

None of these comments are meant as criticism, I appreciate all your work on many Model T drawings.

Sincerely, jb

Martynn, is there a depository of your Model T drawings? I did not find one on your website and they are too interesting and useful not to look at all of them. Thanks. Mark

Mart ! What's with the weird looking bolts that secure the driven plate ??

George, those are what is suppose to be in 26-27's because the drive plate fits down within the brake drum on the transmission...what those bolts do is put the bolt head above the rear surface edge of the brake drum so you can wire them easier...of course you can use to pre 26-27 bolts too, just that you'd have to wire them down inside the recess.

James, the numbers on the driven gear are the count for setting the timing of the triples...every 9th tooth (the tooth count on the driven gear is 10 pitch, 27 teeth. the same as it is the direct drive gear on the triples, so 27 divided by 3 (the three triples) equals 9...so every 9th tooth of the driven gear fits into the marked section of on the triples)...couldn't make them any larger without making everything else harder to see.

Mark, if you're on Face Book, friend me at Martynn Vowell...my albums are free to use by my friends, you can see just about all of them there, the only downside is that they are the same as here, half size 6"x4", 150 dpi, 24 bit (I draw them at 8.5"x11", 300 dpi, 64 bit).

At one time Chris B. the forum moderator was going to put them here on the forum under the title "Drawings" on the main menu (I think you can see the 1909 stuff still), but we never got beyond my rather limited 1909 stuff...the idea was that there would be a thumbnail picture of the drawing, with a brief description of what it's about. Once you clicked on the thumbnail icon you could download a full sized PDF and or JPG in 300 dpi 64 bit like I draw them in. These I post here are about half size 150 dpi 24 bit because of the size constraints. If in the future the forum and it's new format wish them to be here, fine by me...wound make it more convenient than telling everybody to go to Face Book and see them there. :-)

Beautiful work Maybe an inset of what large and small discs look like separately would be helpful

I thought they were odd, after seeing your tranny and Derricks. Next time I have the inspection door off I'll take a look.

Tom or maybe just a note with the part numbers calling out the round one from the hex one.
