The HCCT Handbook will be available to ship starting March 1, 2020. Pre-ordering is available now by calling the MTFCA Business Office at 765-373-3106. It will be listed in the MTFCA Online Store March 1.

No, not necessary. If the Cap somehow needed electrical insulation, so would all the bare wires inside the potted assembly. If the rationale is that the Cap needs thermal protection from the hot tar, that .004" layer of fiberglass tape isn't going to do much. In addition to the electrical characteri...

Mike: The lid on my '26 coupe is 34 3/8" at the lower lip below the keyhole and 36 3/8" wide at the hinge point at top. Measuring along the curve of the lid sheet metal from upper to lower is roughly 37 3/4", which leads me to conclude the lid you have is for a coupe. There were no rumbleseat model ...

Tommy: I'm working on a '26 now, what do you need? Don Booth has posted on this subject a number of times on the forum, he helped me a bunch. Best, jb

The lugs appear to have been filed, maybe more than once, do the the plates still bear equally against all six lugs? It's tricky to hand file these to exactly match the plates. Not a criticism of your work, just something to consider, best, jb

Check the pedal notch fit with a new hogshead notch and go from there. Good luck to you,

There are a number of previous posts on the Forum, this one seems kind of neutral. I do not have a preference, best, jb

I recall a post where a small diameter wire was laid in a circle in one of the mating surfaces to act as a shim and a liquid sealant applied to seal the joint. Not a recommendation, just an observation. If this was my T, I'd look for paper/cardstock of the desired thickness and try to trim a 'gasket...

Apologies for this diversion, but I wish to thank Ron for posting this helpful response. Ron has helped me personally with Model T electrical challenges and has shared his knowledge selflessly with the greater Model T community. Ron, I hope you continue to share your knowledge through this Forum. Re...

Congratulations, Steve. You're 'it', every poster on this thread has complied with your order!

From the table, Red oak and White oak have 71% and 75% the bending strength, respectively, of Hickory. Bending is the limiting strength in the kind of failure altair describes. Not a guarantee that Hickory would take that abuse but it would handle 25-29% more than Oak. jb

This topic has been discussed in previous threads which include some photos, not all of them great however. Here is one example: http://www.mtfca.com/discus/messages/506218/557770.html?1437802483 As stated above, hickory tool handles are good examples, if you can find a hardware store that sells hic...

I suspect it's a simple error, nothing sinister. I wouldn't worry about it. jb

Bob: Thanks for sharing. The 'modern' iron in those movies is nearly as interesting at all the Model T's. If I could offer a suggestion, it would be to include a note at the beginning of the flick giving date(s) and location of the footage. I grew up in the Midwest and likely visited some of the pla...

Luke: As Dan stated, only the bifurcated brass rivets should be used for transmission band linings. There are many forum and written references to best practices for transmission band renewal. Best,

Here's a used set of drums http://news.cornell.edu/stories/2020/01 ... ose-jan-31 The small chip in brake drum posed no problems to previous owner. I know these are '26, but obviously quality parts nonetheless. I have no affiliation with this seller. jb

This is a great event! We attended last year, met some nice people, took several rides on the vintage iron, enjoyed being outdoors on a beautiful crisp early spring day. Thank you Chad and all the others who welcomed visitors like us to your event! jb

For 24 pitch, one turn = 0.0417", 1/36 of a turn 0.001157" so yes, 10 degrees of rotation is just over one thou, if that is still the question, best,jb

Lang's has always 'done right' by me, great service and buying experiences similar to what others have posted. I have also had similar good service from other vendors, and I'm glad we have them. Recently I ordered body patch panels from Mac's on ebay, and that product and their service was exception...

Luke: Do you have the inductance values and corresponding rms current/HCCT current values for the coils after the coils were all set to fire at the same dwell time? If you do, would you mind sharing the data? Thanks, jb jab35(at)cornell(dot)edu

Luke: As always, I appreciate your efforts and continued sharing of info. IIRC, Voltage and inductance are involved in this process, so you may need to look at both values to better understand the effects of varied excitation voltage and possibly, coil to coil variability. For sure, inductance value...

Will these work? https://www.modeltford.com/item/5205BX.aspx

Carson: Welcome to the Forum. I think engine seizure is unlikely. Are you sure you don't have the car parked in gear, hand lever fully forward? If parked in neutral, the clutch could be jammed ( which I think is unlikely) jacking up one rear wheel and turning crank would help identify that, crank, e...

From the April 1928 Street Repaving photo:
“The area that doesn't have asphalt will be paved with granite, re-using the old blocks from the street, so that oil from parked cars won't ruin the asphalt.” Apparently the Model T was not the only car to leak oil.

Thanks for sharing the photos, jb

When I did mine I made an axle support using square tubing and some angle iron. I welded a plug in one end of the tube and welded an angle iron 'collar' around the outside of the open end, making the finished tube a couple inches shorter than the distance from the threaded end of the axle to the poi...

That article is excellent! Here's a summary article showing the phase diagram for various Alcohol, gasoline and water combinations. Saturation by water occurs at a water content roughly equal to 5% of the alcohol content, same as was observed in your reference. Good info, jb https://www.iea-amf.org/...

Steve: Are the 27 defenders the same 27 who correct grammar and spelling, etc? If so, I'd say you are doing well with this interested group of people who want the information and are also willing to spend their valuable time to make you a better writer. Keep the sparkplug posts coming! jb

Nice work and good results. First a question, is capacitor leakage important? and if so, how difficult to measure? I suspect the first 4 values for 4 new caps is indicative of the variation one will find in new parts. If the variation affects coil performance in a negative way, I suppose you could s...

This may be old news, Ethanol dissolves shellac and shellac was used to 'seal' the original mag coil wrapping and 'glue' it to the core. Gasoline can get into the crankcase (particularly at start-up/running rich in cold weather, flooded engine etc) and ethanol in that gasoline blend can attack the m...

Wow! Here we go again and in a large type font no less. For a short time I thought 2020 would be a better year for our Forum. FWIW, my Gilbert pendulum wall clock with 7 Day movement is accurate to within +/- one minute per week (compared to my Ironman wristwatch). I know that I should be checking i...

Thanks, Luke. I appreciate the offer to receive future data/results. Since you have only one coil, one thing you might consider is slightly adjusting your coil by making small adjustments in the lower bridge. (I do this without a hammer because I don't like pounding a coil in (or out of) the testing...

Luke, Matt, Chris: If you are going to incorporate rms current in your output, I'd suggest calculating it using the general equation shown in the video. If you can sample Current at known discrete time intervals during the coil firing event , your computer should be able to square that value and Rei...

Thanks, Luke: Not trying to make extra work, but the SDEV gives more info regarding consistency than range, but both are important. Range is obviously determined from the Hi-Lo values in the sample data. Range would be the same if you had one outlier value with others closely grouped or a scattered ...

Luke & John H: Thanks for your information. Regarding Variance and SDev, I feel if you give SDev that is sufficient, and preferable as the SDev is the square root of the Variance and all that could easily confuse us. Note the units on Variance would be (mSec Squared) so I'm not sure the reported val...

Luke: Nice work, thanks for sharing. IMHO, Mean, Range and SDev would be essential information. Another question I would like to explore concerns the Current and associated dwell time for firing each coil. This has never been presented in any comprehensive way to my knowledge. For example, if I set ...

Quoting 24t: "My timer is a very early model he made with the larger brush."

Luke: Thanks for sharing all this. I do have a couple questions. Is the coil really firing at a current of only 15-20 mA or is there a scale error on the graph? On the double spark coil, have you checked the cushion spring function? If sticking, it's sometimes possible to free it up to improve coil ...

Nice video, like a Richard Eagle painting coming to life. If you did the work yourself and you work for free, it would not cost a lot to finish the ceiling, insulate and sheath the interior. That would hide the 'patina', unfortunately. All the best for the holidays, jb

Boy oh boy, you sure showed him!!

Happy Christmas everyone, jb

I encourage all of you with interest and theability to develop and share this technology to run with it. Once you have a tested design you could offer it for sale in classifieds as a complete unit, a kit, or list of parts with assembly instructions. I think that would be service to the model T commu...

Could a bronze or SS coil spring be used the this application? Just curious, beautiful work on those, jb

FWIW, I just received a 6v regulator from Birdhaven, it arrived less than a week after I ordered, but I know these have been out of stock in many places for a long time. The rumor I heard at Hershey was the following: When Funprojects manufacturing was taken up by Birdhaven, the manufacturer used a ...

Here's the parts, I could not readily find the bolt diagram with specifications for 26-27 but it does exist. Two cap screws and shims as needed to secure hogshead to back of block, best to you, jb

In Dennis' pic the rope may pull against the valve stem. I always avoid threading a rope 'chain' thru that spoke opening, fwiw, jb

Wouldn't running on battery with magneto disconnected but loaded with an 1157, 12 volt automotive bulb and ac voltmeter determine if the mag 'cuts out' ? Perhaps the bulb alone would give indication, if it dims at higher rpm it would confirm Ron's diagnosis of excessive flywheel clearance. good luck...

Richard: On my '26 coupe the brackets with the threaded stud that mount to the 'A' pillar are installed so the stud is below the center point between the two screws. If reversed, the stud will be above the center point and I think the stud and windshield bracket for the arm will then interfere. See ...

Richard: I assume when the windshield was removed the adjustment arms were left in place? On my '26 coupe the arms and brackets holding them to the window frame appear to be held with machine screws. Likewise, the studs on the A pillar are machine screwed to the pillar. If nothing was removed previo...

The tool Mike displayed at Hershey is a version of the coil points adjusting 'hammer' you see in the ford service manuals. It is laser or plasma cut from steel plate.

Justin nailed the removal, it requires a substantial side cutter as shown.

Keys were snug in axles as they should be, gears pressed on with ...

Melina: Here's an earlier Forum post on Model T keys. As with many model T components, there were multiple suppliers of keys. Possibly 'C-D' supplied keys for Canadian Fords? Briggs also supplied many model T keys. You can get an idea of value from the internet, original Model T keys are almost alwa...

Even tho it spins freely, do check the shaft as advised. I would not use new needle bearings on a worn shaft. best, jb

Ron the Coilman does not vend at Hershey, at least he has not in the past years. John Regan would likely know if Ron plans to visit Hershey this year. Respectfully, jb

Starting with timing set 5 degrees before tdc could break an arm or Bendix. Too bad peer review happened after publication. Hopefully a correction is printed in the next issue, the article is excellent otherwise. jb

If I ever get to this on my '26 coupe, I plan to use hardboard material covered with non woven landscape fabric. The fabric looks old going in, and will likely age gracefully inside the trunk.

I'd rig it up with a 6v battery and some jumpers so you can test the coils with the plugs. Don't get bit! jb

With all the 'soot' visible in earlier pics you posted, I'd be surprised if valve function isn't compromised. The combustion chambers and valves are at least as sooty as the plugs you showed.
