Thanks, Bainford. Excellent explanation. I had asked SEL a couple of questions about scale size on their tires and wheels. Below is exactly what I got back from them. It makes perfect sense to me. I have read a few posts where guys mentioned that the wheels & tires included in a kit were either too small or too big for the car itself. With a couple different sets of wheel & ires from SEL on hand, that should never be a problem for me again, at least I hope.
Now, onto scale.The thing to keep in mind is by taking the attitude of
"Well, the box says 1/25 and come hell or high water that's what i'm gonna
use!" will simply make you crazy. Over the years manufactures have fudged
the scale in many places on models. this can range from a wheel being a
bit undersized to the entire kit being out of proportion, rendering it
worthless except for a building exersize. Build to what looks good to you,
and what fits your memory of the cars you are trying to replicate. Unless
you are building for a judged competition, you are not going to get called
out on it.
Consider this, 1/25 and 1/24 scale are roughly 1/2 inch equals a foot.
Roughly because neither are 100% 1/2 inch scale. Look at a metric ruler.
One inch is equal to 25.4mm, therefore one mm is roughly one scale inch in
1/25 scale. Consider the extremely small size difference and you will
understand the "Build so it looks right to you" concept.
