I've been reading many of these posts of the last few months and enjoying the wealth of knowledge and pictures shown here on various Model T components. This is a wealthy community to say the least.
I was inspired by much of what I've seen at this forum, to actually create a project and bring it here for critique. I looked at several animations of how the T transmission works, but they are a bit vague to say the least, and some just don't reveal enough. My own curiosity has led me to draft up plans of each part (which I have been amassing from e-bay) and then take them into my Rhino 4 3D program to create as 3D objects. The final result would be to actually create a 1/2 scale model and reproduce the parts in plastic and metal, somewhat like Renwal's "Visible V8" engine model.
So, if anyone here would be gracious enough to help look over my prints and progress, it will be a real challenge to see if this can be created. Not unlike the T engine animation that I saw here, done by a member's daughter, as I recall. At any rate, I will either display the work in progress here or on my website.
I need to take photos of the parts I got, and sandblasted to clean up. Was able to acquire some rather nice parts from Canada, and have a very unusual reverse drum, which actually says "Made in Canada". It has a thinner, tapered front ridge and wildly different teeth (look like they are all heavily angled on onside and seem to not be straight as they progress back towards the curved section.
I will try to show these variances in photos and then post them here.
Thanks in advance for your interest in my project.
Welcome, Jim. Nice project. If your travels take you south from Valencia, I or others could lend you parts you might need, or even a whole tranny. Otherwise, the Bakersfield old car swap is in April; San Diego end of Feb.
Are you related to Billy in Wirelake, NM, or Francis Scott?
Your project sounds intersting. Somewhere on youtube there is a fantastic animation of the assembly and operation of the Model T engine assembly. The above link is from the Model T Central website. It has been very helkpful in explaining the operation of the T Transmission and you should find the simple animations interesting .
Yes, I've seen it, but the low-speed animation is deceiving and not correct in how it actually works. Driven gear is actually "carried along" through reduction by the triple gears, much like in neutral the reverse drum spins as consequence. A little more of a animation exactness, than what is shown, though his reverse is closer to the actual truth.
No, not related to either party. Tried to prove the Francis Scott Key one, but no positive proof.
I have all the parts except the bands, case, flywheel, and early riveted triple gear. I suspect my reverse drum was made in Walkerville (Windsor, Ontario, Canada)as it is stamped with a "W" and has a different front rim - probably for a truck version. Also a tapered gear edge - very strange looking. Not so much wear, as each tooth is very differently shaped. Also my one -piece triple gear tends to lock up on it.
If any lenders wish to contribute, I'd be happy to sign a promissory note and pay shipping to/from our studio in Chatsworth, CA.
I'll try to start getting pictures of the parts and drawings up soon. Not sure what the best .jpg size for upload, but will ask and find out.
Thanks for the warm welcome.
My neighbor goes to his powdercoating plant, Fusecote, in So. El Monte quite often. Could you pick up parts from there? The flywheel is heavy, as are buckets of other parts. They're not clean, however.
I have a flywheel with new pins, and the triple gears with new bushings all ready to go.
Cost? Another neighbor's grandson is Sr. in some smart kid high school in Carson, and is published in the latest ITEA, International Test and Evaluation Assn, Journal, on prototyping. Would it be worth his while to visit your operation?
Max size jpg is 200K.
From itea.org :
"The articles begin with a special student section arising from the ITEA Annual Symposium Academia Day paper competition, held in Huntington Beach, CA. First place winner, Bradley Matheus, senior at California Academy of Mathematics and Science in Carson, CA, outlines the benefits of numerically controlled machines and 3-D printing for rapid prototyping."
Here's a test peek at the sectional WIP
As to the rapid prototyping, no not worth his while, as I have all those connections already in place and if we make 1/2 scale model of this, I will not doubt rapid prototype all the parts as well as have the gears investment cast in zinc to make the master patterns.
Most of this next few months will be all CAD work to create the 3D files.
Thanks for the interest.
