Ghostchips 1920-26 ford T bucket (of rust)

New brake lining.  It's a bit too thick but i will make it work.

[Ghostchips 4,805]

 

Ugh, close enough.  Cant be bothered fitting it better at the moment.  Think i'll sand the paint off though.

Hood tie down strap made from a leather belt.  The belt is so long it forms a loop for someone 3 times my size.  Could wrap that around my waist 3 times before it met the first belt hole, and it has a functional lock in it.  Why would it have a lock?

 

 

 

So i don't know if i should start a technical thread on "How to make trembler coils" as mine are toast and one of the borrowed ones died today. Never successfully made an ignition coil before, i think i'll need help of the electrical gurus on here.

[Ghostchips 4,805]

Someone had deemed these "junk" and left them in a fish bin full of water outside for a year.

Some time ago i cut open a dead RB25 coil hoping to see what was inside.   Such fine wire, so many windings. About a million of the finest wire windings i had ever seen, trapped in resin plastic, sealed and unable to be unwound at all. At least by any methods i could see.

These 100 year old ford ones remind me of the same thing, except the wire is slightly thicker and there is 2 lots of 1million windings.  2 per coil around a heavy primary winding.

Accidentally put a chisel into the primary and is still works.  Not for 100 years anymore as it'll corrode now it's damaged but still... not many ignition coils you can pull the windings out of, involving chipping away or melting the tar they were packed in.  Those brown paper things are capacitors.  Condensers effectively, like you have for a distributor.

While i'd heard of old timers making their own from paper and chewing gum wrappers back in the 1940s when they were poor kids fixing their first car... i'm not that keen.  These had real tin foil, not the alloy foil we have today so they solder really nicely.  A couple tested within spec' so i re-used them.  Others i replaced with orange things.

Mix and matched the wood.  And going ot do the same with the burnt out windings so i can turn 8 burnt ones into 4 good ones... hopefully.

Had some burn up after 10 minutes of driving because i didn't realize how keen they were to have inch long sparks jumping inside the box if i didn't put the glass plates and tar back in.  Opps.

Bit marked up, some have clear borer holes in them but not too bad for 100 year old ignition parts.  How many of you are still running original coils and points at 1/3rd the age?

Have i tried to sell you on the merits of LED lights lately?  Even on high beam the amps draw is maybe... 1.2 amp?  According to a century old gauge anyway...  much less than the 10 amps they were previously drawing.

And other people can actually see the lights now.

[Ghostchips 4,805]

RockAuto is really low on stock, wonder why.

Factory drop spindles still available, used.

No UK spec' ones available though.... NZ got canada spec ones.

[Ghostchips 4,805]

So some of you are really into programmable ignition and electronic sensors.
I tried to make my own electronic ignition.
After 3 seconds one of the MOSFETS running a coil shorted out.
After 7 seconds all of them had.
Each mosfet was rated at 20 amps.  But considering they were dealing with the primary and ... lets face it. some of the secondary output (These old timers are like that) i don't think they were up to the million volt task.

At least 2 hall effect sensors survived.  Barely.

"Straight through" Holley NH carb's share many parts with the economy version carb'.  Same basic thing, but the economy version had more restriction.
I'd be tempted to smooth the venturi a little, as it has a rough finish, but don't want to mess it up.  I'll choose to believe that rust pitting help the mixture.

So i filled in some pitting around the rim of the bowl seal with an epoxy.
Used white metal normally used for engine bearings to build up work throttle shafts.
Drilled small holes in the broken castings and poured white metal into them to build up the areas where casting had broken off.
Built up the worn nut with more white metal.

First i tried to replace the bronze throttle link with chunks cut from a worn bronze bushing, that turned out to be fragile.
So i riveted and soldered, with more white metal (more resilient to vibration than solder due to no lead content) copper strips.
I choose to believe i have improved this carb's condition compared to when i found it.

The tail lamp was suffering metal fatigue.  Not surprising, given its alloy.
So i made one fitted for the electric light.  (re-used the old glass)

That's not paint, that's indian head shellac.

[Ghostchips 4,805]

So i heard you think recycled plastic is crap?
I disagree.  I am an enthusiast of it now.

[Ghostchips 4,805]

Diff' oil is sparkly.
https://youtu.be/Mle73Vxxipw
So i put a camera in there.  Nothing much to see.

 

[Ghostchips 4,805]

 

This would be awesome if it didn't make so much interference.

[Ghostchips 4,805]

So i tried making my own coil on plug system with a piece of plywood with magnets glued in it in the front of the cam,  an arduino pro mini with sensors mounted on the front of that, a sheet of plastic (Made from melted milk bottles & bottle caps) with copper screwed to it to distribute power i know those aren't proper ferrite toroids but thaat's just too bad.  Wrapped in a tin foil tape to try & keep interference out (probably keeps it in?)



The cool kids have MS paint graphs & stuff so i'll try be be cool too.
The red curve is a rough approximation of how the standard magneto behaves.
The green one could be programmed any way i like.
If i put a high(er) compression overhead head valve head on it, then i can program a curve to take advantage of it.

It'll also make old grumpy people sad.  Most people just use a distributor conversion.

[Ghostchips 4,805]

Video of it almost running.  Cannot seem to get the mixture quite right.

[Ghostchips 4,805]

Turns out i need to use the cylindrical style transformers, they need a longer ramp up time of at least 8 milliseconds, ideally 10-12.
The little cube ones are nice but they seem to foul.  Although the cube style produce a hot enough spark to burn paper & start to melt the spark plug electrodes, when fouled with fuel they can't even light a pan of fuel.
The cylinder style build up a charge and discharge it all at once, this appears to help with the 'self cleaning' effect. A big plug gap will make them lag like crazy, but the spark is loud enough to hear from outside the engine block.

 

[Ghostchips 4,805]

Ardunio nano on a small board with some hall effect sensors. installed in the end of an old can, some melted plastic in the holes, light passes through the plastic so i know where to drill it to put the bolts through.
 

 

[Ghostchips 4,805]

Picture-less update.

While i will still need to dial in the auto-advance curve (the orig' relied on a combination of moving a lever to a basic range, and the magnets on the flywheel ramping up the speed of the points opening) it has a notable improvement in fuel economy, partly due to being able to wind the fuel mixture screw in 1/16th of a turn & have the same performance.
It's like having the magneto set perfectly.  But requires a battery.

[Ghostchips 4,805]

I can wind the mixture screw in 1/8th and not melt the pistons.

i also made a music player for summer.

 

The first one, had no support for remembering where it stopped playing when it was turned off & i didn't want to stress the EEPROM by writing to it every time you changed a song.
So i made this hilarious work around.

Ultra capacitors running the player for a few seconds after it is turned off.
