Okay Ken. I gotta ask this. And PLEASE do not take this as a bash, because I certainly don't mean it to be. I have nothing but respect for you and the astounding work you do.
Why do you scratchbuild everything? I mean, while impressive, your wheels and tires are not nearly as well done as whats available in kits or aftermarket. The time saved alone would make it worthwhile. Why, since you are assuming chassis design, don't you just use one from a kit with a similar wheelbase and chassis design?
I can understand the sense of pride, of saying "Yep, I built that from just some plastic sheets and tube stock." But the bodies and interiors ALONE are so impressive that NO ONE would fault you from doing some kitbashing to help move things along and onto the next project. There are so many projects I want to accomplish as a modeler and only so many days allowed on this planet. If I can make "this" work by using "this" to help move it along, I certainly will.
We obviously have two different work styles and ethics even. Looking forward to your reply.
