There are two museums in the area...America’s Car Museum (off I-5), and the Lemay Family Collection at Marymount (near Spanoway). I visited the second...LFC, and probably the largest by far. I haven’t been to the ACM yet. I think there was a falling out between the two because the ACM sold several hundred of their vehicles at auction (which they had agreed not to do). The Lemays from the LFC visited the auction and bought over a hundred back.
An incredible collection...just pure history.
Car ping.
“I’m an excellent driver.”
K Marts sucks.
“Sounds like the beginnings of Death Wobble to me.”
Didn’t sound like the steering wheel was wobbling.
“rolling motion (clockwise from wheel to wheel, front to rear)”
Of course it’s time for Judge Wopner.
I had a 59 Ford Tudor that did something like you describe at 60.
Around 60 where that type of vibration shows.
Drive-line vibration tends to show around 30-40.
Shocks? Maybe, but balance the tires first.
I don't know the availability of the shocks, some old and I guess they have to rebuild them?
Old bias ply tires can flat spot too, they can take a while to round back out.
ima just sit here and live my life vicariously thru u.
I guess a set of Koni shocks would be out of the question...
“Harmonics of a perfectly balanced machine. Like the hum in a Hotpoint washing machine in spin cycle. Hint, I was a builder and rebuilder of these machines. When they are right they have a song they sing. I think this is so with all mechanical things.”
I’m a mechanical engineer. These are known as mass-spring-damper systems. You can do some really elegant analysis of these systems with something called Laplace Transforms, shows all the sinusoidal movement. As long as you are in bounds, enjoy it.
What you are describing is beautiful.
When I was 12 I was given a 1927 Packard touring car (my first car). The back part had been cut away and a flatbed put on to make it a “truck” during the early part of the war.
It ran fine, but without mufflers was a tad noisy. One of the neat features was it had a built in lubricating system you could pump (inside the car) to manage the squeaks.
When I got to school (high school freshman), after a 22-mile drive, everyone knew I had arrived.
The only thing I couldn’t do with the car was get girls to go on dates. Now, at 84, I cannot remember whether it was a straight 12-, or 16-,cylinder engine...Which ever it was, it was a long as today’s Ford Focus...
When I was a sophmore, I traded it even-up for a 1935 Ford (mechanical brakes and flat-head V8). That car got the gals...
many suggested new parts or other fixes ( shocks, tires, tie rods) all of those will be addressed as time and money allows. There were several costly items ahead of those: electric harness, brakes, trans overhaul.
as to the swaying motion I described, I hope, as those items are addressed, the motion does not dissipate, as it makes for a very enjoyable ride. It is almost not noticeable, until you do in fact sense it. Once you do it seems to then be something relaxing and very pleasant.
I really was looking to see if anyone knew the cause. I do believe the natural reasonant frequency is likely the most logical answer.
Thanks again to all!
Well you did have your priorities in order!
That sounds so good, I’m going to be begging for a ride in the next 48 Packard I see.
I just got off the phone with my brother, who has been my right hand during this project (he is a motor-head). He said that it could not be a strait 16. He also added that some companies made a straight 12, but not Packard (they tried, but it never went anywhere). It was either a straight eight (standard for Packards) or another engine installed in the Packard.
It’s a great museum! The only (tiny) criticism I have is that they have so many cars and so limited space that they are forced to rotate the cars on display. You may not see your favorite the next time through.
I spoke to my brother and he knew right away what you were talking about.
Bias ply tires, do you have bias ply tires?
All of his cars with bias ply tires are, what he called, ‘floaty’.
It should go away with radials.
Hope this helps.
That is what we have. Thank your brother for me.
And tell him also: I don't want it to go away!! It is a great feeling when the car gets into that rhythm (or float).
And 'floaty' is the perfect adjective for it.
