ok, that's just the teeeeensiest bit more involved than I planned on getting... But I did download a bunch of his photos for reference. BTW... wow, do I wish I had the machine tools he has!

You can shop on their website.

How did you make the rivets on the fenders?

Dave is all about huge wheels. He puts them on just about every model.

What a coincidence! I'm working on the same exact kit, and also made the firewall/dash out of real wood, and also will me making the floorboards out of real wood, exactly as Christian is doing. Ian, the kit is simplified, but a great starting point. Adding extra detail is easy, and should make for a good looking final product.

Yes, in your example the outer runners would need to be running faster in order to keep up with the inner runners, because the outer runners have to cover a greater distance (the farther out from the center you go, the larger the circumference of the runner's lane). But in my example the "runners" (the dots painted on the disk) can't move independent of one another. The outer dot can't "run" faster than the inner dot; they're both painted onto the disk and can't change positions on the disk. Their position on the disk is fixed and immovable, therefore by definition, they both have to be spinning at the same speed as whatever speed the disk rotates. Yet the outer dot covers a greater distance per revolution.

The starting lanes on a track are staggered because the outermost lane is longer than the innermost lane. So in order for everyone to have to run the same distance per lap, the starting points are staggered. Plus, each runner is his own separate entity... one runner's speed is not connected to another runner's speed... thay all run at whatever speed they can, and the fastest runner wins the race. But that has nothing to do with what I'm talking about. My "bugs" are sitting on a rotating disk. Both bugs are sitting stlll, not moving in relation to each other. The bugs could be two spots painted on the disk instead. Both spots are moving at the exact same speed (the speed of the rotating disk), unlike runners who move at their own speed, independent of the other runners. Both dots make one revolution per second (the speed of the disk that they are painted on), both dots take the same exact amount of time to make that revolution, but the outer dot covers more distance than the inner dot in the same amount of time. How is it possible that the outer dot travels one mile of distance in one second, while the inner dot travels only one half mile in one second... yet they are both traveling at the same speed (the speed of the rotating disk)?

But you have to know what you're searching for in the first place!

I guess where I get hung up is the fact that the entire disk is rotating at the same speed, yet the two bugs (who are sitting on the disk and are both traveling at the same speed-the speed of the disk) cover different distances during each disk revolution. Imagine a stationary "finish line" above the disk, going from the axis straight out to the outer edge... and then imagine the two bugs on the disk, one sitting on the outer edge and one at a point exactly halfway between the axis and the outer bug. Both bugs will cross the finish line at the same exact time, even though during that one revolution the outer bug will have traveled one mile (the circumference of the disk) while the inner bug will have traveled only one half mile (the circumference of the disk at the halfway point between axis and outer edge). So even though each bug completes one revolution in the same time span (one second), each bug has actually traveled a different distance in that same one second of time! Maybe Christian can explain...

Ok, this one might have been too easy! Too many of you got it! It's a 1962 Daimler SP250 Dart.

Man, that's some very impressive metal work!

With the stuff being put out by Polar Lights and Moebius, plus what the "big guys" are doing, yeah... it's good times!

You're not following. Outside bug goes one mile in one second. Inside bug goes 1/2 mile in one second. So outside bug must be going twice as fast, because he goes twice as far in one second as inside bug does. But they're both on the same disk, spinning at the same speed! They're moving at the same speed, but outside bug goes twice as far!

Yeah, the center bug has a shorter distance to travel. But both bugs travel their respective distances in the same time! How is that possible? How can center bug, who has to travel one half mile per revolution, and outer edge bug, who has to travel one mile per revolution, do that in the same amount of time (one second)???

Man... I thought I did a pretty good job with this kit until I saw what you're doing. I officially hate you.

Sean... very cool! What a neat mix of eclectic subjects, every one perfectly done. You have definitely had a great year!

But Skip, in your example, the runners are discrete objects that move at their own pace independent of the others. Ok, let's look at this another way. Imagine a horizontal disk exactly one mile in circumference. It rotates on a vertical axis. Let's assume it rotates at a speed of 60 RPM (one complete revolution per second). Place a bug at the outermost edge of that disk. If the disk is rotating at 60 RPM (one complete revolution per second), the bug will have traveled one mile (the circumference of the disk) in one second... right? Now place a second bug exactly halfway between the axis and the outer edge of the disk. In one rotation of the disk, that bug will travel only one half the distance that the bug on the outer edge will travel, because that bug is sitting exactly halfway between the axis and the outer edge... or in other words, at the point where the circumference of one rotation would be one half mile. So the "halfway bug" travels 1/2 mile per revolution, while the "outer edge" bug travels twice as far (one mile) per revolution. The disk takes one second to make one revolution... so no matter where on that disk the bug sits, it will take that bug exactly one second to make one complete revolution. Yet the "outer edge" bug travels twice as far as the "halfway bug" per each revolution. Does that break some law of physics? Here comes the headache again...

Yeah, I've heard good things about them. (plus, they're a magazine advertiser... ). Maybe the January/February sale is an annual thing. If so, it should be right around the corner. I'll keep my eyes open... I've been wanting that big one for a while now! It looks like a fine product.

So back to the bugs... One bug is sitting on the hub of the wheel and another bug is sitting on the rim. The hub and rim (the entire wheel and all of its parts) are rotating at the same rpm. But in the course of one wheel revolution, the distance traveled by the bug on the hub is the circumference of the hub, while the distance traveled by the bug on the rim is much longer-the circumference of the rim is much larger than the circumference of the hub. In one wheel revolution the bug on the rim has traveled a much longer distance than the bug on the hub, yet they were both rotating around the wheel's axle at the same speed (the speed of the rotating wheel). How can that be? Does time change relative to the distance from the axis of rotation? Does time go by faster on Pluto than on Mercury? Is time not a constant? Does time depend on where you are? If the bug on the hub and the bug on the rim have both completed one revolution of the wheel in the same amount of time, how is it possible that the bug on the rim traveled a much longer distance in the same amount of time? Now I really have a headache!

The further out you go from the center, the more distance you travel. The hub of a bike wheel rotates at the same speed as the outer rim (same rpm), but during each revolution the air valve travels a much greater distance (the circumference of the wheel) than any given spot on the hub, even though both are rotating at the same speed (rpm). So if you could scale yourself down to the size of a bug and sit on the rotating wheel, you'd get a much greater sense of speed as if you sat on the rotating hub, even though both the hub and the wheel rim are rotating at the same rate. Whoa... I'm getting a headache...

I'm thinking of getting the big one... I see they at least offer free shipping, so that's something.

So the faster you go, the slower you go? Whoa. Dude. What a concept.

Do they ever have a sale or go at a discount?
