MTFCA Forum

I went to vote on my way to work today. The voting center is next door. This evening as I was walking I shared my regret- I forgot drive my Model T! I was planning to, so there could be at least one thing that I would enjoy about the process!

It sounds like it is too new for you. How about I give you $40 and your send it to me:)

John,
Thanks for the info on the color LED. I would like to make this an option on the printed circuit board. Could you send me information on the wiring connections?

Thanks!

Matt

Looks like a good deal! Why don’t you get it?

Wow! That is a lot more work than just restoring a engine!

What a treat to see the posts! I missed an earlier post and didn't realize there are new posts. Luke, Thanks for your insight. I will probably do my experimenting with actual PCB. They are only $2 each plus $5 to add parts and the cost of the parts. I know someone who got a board done and was surpri...

Busy week! Thanks for everyone's comments! The saga continues... In short I enjoy Model T people and have yet hit it off with watch people. Update on my end. I found a new forum on Facebook (I use this forum 100x what I do Facebook... and don't really like facebook, but ended up adding a bunch of cl...

It looks like the reason is obvious to all of you and maybe even me in hindsight. The forum is actually a part of a website. I was able to go on to another computer and enjoy the website. The website looks like it’s purpose is to charge people on training watchmaker. I found there was a statement th...

First, I will say one reason I am posting this is I am really glad for MTFCA forum after this experience. I do understand that we get spammer/scammers on this forum and weed them out. But I hope it never gets to what I experienced on another forum. Yesterday I bought some metal draw cabinets. My int...

Nice way to celebrate labor!

Mike, Your comments are appreciated! I will also say that in the handful of words there is a lot of wisdom packed in there! Yes the "opportunities" to learn are many more in this project. Steve, I am building this open source. When it is more stable anyone could take the files and have the PCB board...

I am working on making a PCB. Attached you will see a schematic and PCB layout. I believe the schematic is close to where we want it. The PCB needs lots of work but gives the general idea, I just didn’t want to go too far without getting feedback on the schematic. You will see that I have tried to l...

What a service you are doing for the Model T community!

Thanks so much!

From my experience and others here a heavier press is needed. I am curious how many ton press is needed?

Matt

Steve, my apologies, I thought you were joking. I appreciate you sharing your experience and wisdom. I have seen where the cotter pins wiggle so much they wear most of the way through the head. It doesn’t seem like the best practice. But here is the quote chapter and verse! 40A2C8DD-6F8E-432D-B305-C...

Chaffin's sounds like the way to go! I was just happy that they delivered the axles to Bakersfield last year. Here are the tools I bought/used. I didn’t have instructions. But you can guess use. 36B07F17-7417-4D14-9DD0-A765650C6507.jpeg 76103B8E-FE61-47D2-9929-685B514F8EE2.jpeg I used one gear to av...

Speaking of lots of things to do with these axles. Back in the day Plomb tool company use to forge tools out of the axles! "In 1922 the insignificant wrench line was expanded. The few wrenches made at that time were made out of Model T Ford axles which were suitable in size and analysis for the comp...

Ignacio, When I removed the gears off of mine, I tried to use a press like yours. No success. I used a cut off saw and they seemed to come off fairly easy. Same press, same jack. All I could conclude was the heat from the cut off saw made it easier. Putting them on, I used oil... For press, I bought...

I needed a good belly laugh!!!

Steve, Your comment about reinstalling the cotter pins was my laugh for the day. The cotter pins do really well sitting there in the head of the bolt. :lol: Gorden, I havn't been real clear. I don't intend to use the saw. I don't plan to hook up a belt and the shaft is actually rusted in place at th...

Today I got the engine started. I believe it was likely the first time in 40 years. The engine was not hard to start. It wasn’t any more difficult than starting my car! I primed it and cranked a couple times then it started. It took a bit to understand the levers, but as soon as I did it worked perf...

I’m interested!

Matt

That is very cool. Let me know if you sold it.

Matt

Thanks for the advice. I added the electronic fuel shutoff because sometimes the float sticks and gas floods down. I want it as a part of the key switch to avoid the case of turn off the fuel at every stop. Is there any good way of using the key switch to run accessories from the battery like you do...

Today I did what I wanted to do for a very long time- I installed a 12 volt fuel shutoff valve. I connected everything up and decided to connect the power to the bottom of the 1926 coil box. It works, but I realized that that now I am switching between the Battery/Magneto. My concern is that the mag...

Bingo Jim!

The vertical wrist pins are even cut before welded. With wrist pins hardened, depending on tools at hand, that could be a bit of work to cut!

Matt

Steve,
Good eye! I hadn’t tested/notice the difference in threads.

Yes, only the tapered threaded one (on right) works.

The photos should answer some thoughts/questions mentioned.

Matthew

Recently a 90 year man informed me he is clearing out his shop. I originally meet him at a garage sale. He had lots of Blacksmiths tools from his grandfather that purchased. In WWII the blacksmith worked at the Navy yards and evidently was recognized for a few (tool?) designs. His grandfather also h...

Or at least when you get it working...
Matt!

Has anyone see or used one of these?

I image they must not have been too good or we would see more.

Matt

Richard, Sorry to hear about the accident! Thank God no one was seriously injured. It is good to hear that you may only have trouble with the fenders/front axle and possibly the frame. At this point your front fenders are better than the ones I have set aside for my Fordor project. Don't toss them. ...

I’ve done my own, using home made testers (recently FACT). But looking at those coils and hearing the price I have to say that I am tempted to get a set done professionally!

Matt

As a side note, I did run into an issue with the OLED display. The display module I got was not from Adafruit, so it took a bit of time to figure out how to use the Adafruit libraries with the display. The display had a sample to use the U8gx library, but the library is a bit bizarre to use unless ...

Kevin,
One could use a T bearing on the outside and you are good to go;) The advantage, if you can call it that, of tractor hubs is there are no brakes.

Amazing how things did change much on the front hubs for a good part of 50 years!

Matt

I image this is no news to many of you more experienced gear heads, but I found this interesting. My dad had pulled two hubs off 800 series ~1954 tractor yeas ago and when I was discussing the price of Model T wire wheel hubs he pulled these out. 9113B261-A93C-450B-929C-724FBE79D86F.jpeg I ended up ...

Steve, It puts a big smile on my face to see your set up! Nicely done! I like the box that you put it in! I think it was a great idea to use the breakout board with the Aurdino Nano. It was a real hassle for me to try to solder and fit everything in. I didn’t even accomplish the capacitor test in my...

Barry, I was hoping that someone would take a detailed look at the code that I hobbled together. Your response shows that you paid attention to details and yes I (not Luke) left some things for you to find. Item 1: capturing more samples than what was intended Thanks for pointing this out. Each samp...

Thanks Allan,
This has been a real education. Now the challenge is finding a way to make a set!

Matt

I picked this up recently. I am sure if you found this on EBay the seller would claim that it is rare ;) FDD5B26C-8B6D-4376-915C-08680A146F23.jpeg (I see at the angle of the photo it is not clear that it is a screw driver, but rest assured it is.) 7363415E-2CA8-4FAF-B90D-EF741363618B.jpeg The guy wh...

I didn’t realize that this would be so complicated. Would this work on my 1926 touring? I don’t have a top to check.
Matt

Steve, You are correct! This was on topic until you posted;) Perhaps each day you could rotate who is “COVID positive”. That person would keep track of anytime someone is less then 6 feet of them, touches an object that then touch, use the restroom that they use, etc. The next day the violators will...

I also got this brass pump with it. The guy who sold it, 87 years old, said this pump was on his grandpas TT.

It has a leg flip down. It is not Ford, but it is working.

Matt

I got this saddle and thought I would pass it along, but couldn’t figure out what it fit. Any ideas?

Thanks,
Matt

I like to learn something every day. For those, like me, who never saw the ball peen gasket making here is a good example:

I am not sure on all the details for an engine swap. I think it is more common to put a Model T body on a Model A chassis. But I don’t know what crowds either have a market for...

I know gaskets are cheap, but I like the idea if I am in a pinch. (And if I just need a gasket shipping can be expensive.)

I wonder how many people think that it was a error that the driver came out from the passengers side by of the car!

Matt

Erick,
Nice tool! Similar to the one that I made out of a Model T frame. What metal did you make it from?

Matt

I agree that it was very informative webinar!

Thanks Mike for all the work that you put into sharing about the time-to-fire method of tuning coils and putting together the webinar!

Thanks MTFCA admins and board for putting this together.

Matt

Ten thumbs up from me!

Great I idea Mike!

I am interested. I imagine no matter when you have it some will not be able to attend. Is it possible to have a recording? I know this is a feature on Zoom, but might require the paid version.

Thanks for offering.

Matt

Donald, Somethings are better documented than others. But in general at the start of 1926 model year there were even some cars that came with wood wheels and black paint. But for the most part you saw wire wheels and color cars in 1926. Then in 1927 evidently you could choose any model in any color....

When will the moderator delete this thread with these dirty topless models!?!

I saw this on ebay, watched the video, and thought the builder (your brother) had a lot of fun:)

Matt

Duey and Wayne,
Thanks for your response. Our cars have lived through a lot! I think what they saw in the late '20s and '30s would be informative.

But my purpose in the post is to hear how others find productive ways to move forward with the hobby despite the restrictions.

Matt

Note: I posted the following this morning. I saw that it was pulled and there was a notice on the General Discussion Forum a note from the administrator: "Stop posting anything but Model T related info here."

Well, well, well! I hope someone finds this entertaining. Things came to a halt on the weekend for me. The EMI burned out my Adruino last weekend. I bought some coils and a handful more boards.

Yes, Steve I am having the same issue with noise. I believe somewhere here Luke mention using ferrite bead on the wiring. Bravo John! That looks great! Is that An OLED or LCD display? Luke and everyone, I did order a larger 1.3 OLED, but it looks like I received the same display:( I took my tester t...

I am not sure if you saw it. In reality I have not got to the new functions so it is basically the same as the earlier v...

That is easy. That is a seat. And parts for a top for a open car.

Matt

John, I bought the display as a 0.96" 128x64, but even if you look at the pictures I think you can count and see it looks like a 128x32. (My understanding is these 0.96" come in both sizes.) I also switched to SCREEN_HEIGHT 64 and nothing displayed) Perhaps I made a mistake, either way please let me...

I look forward to hearing experiences of using a Megger on coils. Obviously we want to find bad coils before putting lots of work into them! I worked on the Oscilloscope a bit.

Luke, Yes, the coils that I mentioned have secondaries that are completely open. What I am wondering is how that would happen. My best guess would be that they were left completely disconnected. I would image that is worse than shorting the output. I can see your concern with a Megger, but I image t...

Luke thanks for the update! John, I appreciate your insight! Here are my thoughts: Inductance tester - I use the Model T to teach basic mechanic/electrical systems. The more things I can teach with just a Model T coil the better in my opinion! I look forward to seeing the solutions for both the indu...

Luke, Please ignore my comments above. I confused the secondary resistance and the capacitor leakage resistance. I don't recall anyone having a concern with leakage resistance in the past. It took me a little while to understand how you were calculating the leakage resistance. I still don't have a 1...

Luke, Thanks for sharing your results. I like the concept of the display. I think I would prefer more digits on the resistance value, unless there is a limiting factor outside of hardware. Like Chris, I am with confused on your capacitance value. Here is what John Carter developed for simple multi-m...

I have commented in length in the past about ethanol taking the stance of in favor. Others against.

James, John & Luke, Thanks for your comments. I hadn't considered the leakage. I figured that just determining the value in a desired range, would confirm that the cap is likely okay. It would be good to see what Luke comes up with as a solution. I am just trying to figure out if leakage is a issue....

Luke, After reflecting and before seeing you response I understood your issue with doing the capacitor test AND connecting up with the MOSFET. I think the issue would be measuring w/o the Radio Frequency Interference destroying the chip when running with the MOSFET. I think we have two options: Buil...

Luke you said: However the really interesting thing was (thinking of Tom's enquiry) when I lowered the input voltage to the coils. What I noticed was that although the current went down (and thus energy out) the timing became less erratic. If I tried a coil at ~7V it may show a SD of 0.01 and a 0.31...

Luke, The BOM is very impressive. If we working as it seems to be, it is well worth it. I have on order the ACS712 & L298 boards. But for now I I played more with with the MCCT and the Current Transformer. The results are looking good, but I imagine with the MOSFET switching things it will look a lo...

Nikolaus, You are not alone in thinking you should match inductance.

I have been setting up my coils this way (using an ...

Could I make a small request? I always appreciate spirited discussions with various opinions and points of view. I believe that our differences on this forum make all of us better informed.

I started this topic back in April. Here is my personal ranking after researching and hearing feedback from others.

I had someone recently ask about how to make a Motor Controlled Coil Tester. I though this thread outlined how to make MCCT, but realized I that I could better illustrate it. Here is the simple design used for the Motor Crank Coil Tester (MCCT): MCCT Design.PNG Simply put the MCCT is a Ford coil tri...

My wife took a glance at this and said, "That looks like the technical side of the Model T forum..." In case you get lost in the discussion.

Luke: Today I repeated some of my earlier experiments, but this time with the tester involved. I include an image from my 'scope below for one of the tests. I used the two coils I have (thanks Chris!) and in both cases the 'time to fire' reported by the tester exactly matched that displayed by the ...

Luke, Here is my code. The set-up is basically the same as yours. Here are the differences: Coil is not triggered from micro controller, I am using the MCCT, but a HCCT or car could be used. The code triggers from current when coil is switched on. Option of two display modes by grounding either pin ...

I havn't posted on the MCCT since June. In reality I didn't do much more on the hardware. It does the job, but has room for improvement. I developed the following manual as a draft, but stalled on the final version since June. You will see that this document is based on the works of others whom I ap...
