Gonna miss him. One of the last ‘true’ car shows that combined education with entertainment.

Hey, safety police - knock it off. David is doing good work. Just because it’s not a concourse restoration to your standards, doesn’t mean it wont be road-worthy.

Good work! There is light at the end of the tunnel and it’s only a 25% chance it’s a train. Bet on yourself and keep going!

Edit - it has been pointed out that I screwed up ohms law and that the current actually QUADRUPLES! That said, since the cranking time is greatly reduced, as long as the engine starts quickly, it should work fine.

Yes, I screwed up ohms law and you’re correct, the current is 4 times what it would be at 12v. D’oh!

I completely agree. However, you have to remember that this vehicle is basically a tractor with a speedometer. There are really no other significant draws on the system other than the headlights, which I suspect, will not be used too much.

Well, considering that it is a Chrysler industrial 30 (230 ci flathead 6) and not a 140 or 162 ci 4-banger, the 6v system was a bit undersized from day 1, IMHO. I upgraded the battery cables to 0 and relocated the ground directly to the starter, had a brand new battery and full tune up and it would start - most of…

David,

Actually, running a 6v starter on 12v doesn’t hurt it at all. Since the torque is the same, and the voltage is doubled, the amperage is cut in half. Say that the original starter was designed for 70 amps. The wire gauge would be designed to handle 70 amps at 6v. Running it on 12v results in a draw of around 35…

Fuck this ‘alternative facts’ bullshit! There is correct and there is incorrect. This is clearly incorrect from top to bottom.

My first thought as well. Checks all of the boxes.

You’re so close! Keep going!

David - You got this. You’ve made it this far, you can do it. Just remember that it’s only as complicated as a tractor with a speedometer. ‘Cause that’s what it is.

Disagree. While the original power plants offer character and beauty, they lack the other important aspects one wants in an engine - power and reliability.

If I can be one of said engineers, I’m in.

Half right. He put a helium filled basket ball in it to make it lighter.

Many reverse gears do not use synchronizers because they are low speed and simpler to mesh. They also usually happen to be straight cut gears but I don’t believe that’s the reason they don’t have synchros.

Good point. My phrasing could use some work. What I was trying to say is that older cars (pre-war) used primarily straight cut transmissions where the gears slide relative to one another. These require double clutching and rev matching to operate smoothly without grinding. This technology was held over in heavy…

Not necessarily true. There are two basic reasons to use straight cut gears - cost/durability and speed. Cost and durability are factors in things like heavy equipment and older cars (before synchros). Here, the straight cut gears slide back and forth and mesh with each other. Low speed, durable, cheaper to build,…

Piano has many meanings in Italian. Pianoforte could be floorloud, planloud, planeloud, plainloud, etc.
