Well by your grandfather's definition, Bob, ANYTHING that isn't 100% scratch built is kit assembly - and here we are in a forum that's all about building car models from kits, so the point is - ?
The blog is "The Anti-Rivet-Counter Jihad", found under the blog button above - but I realized it's actually covering a parallel issue, and not hitting the kit-assembler thing head-on; must have remembered that from about fifty other posts I did, so here we go again:
To call somebody a kit assembler is to say, necessarily, that his skills as a modeler are somehow limited. It is one of many devices used over and over again to personally attack people criticizing a kit, presuming the critic only criticizes because he can't fix the problems himself. The equally illogical flip side is, real modelers never criticize, they just fix the problems. It assumes that you can't be a modeler, that you can't BUILD, and criticize at the same time, which is a ridiculous assumption on its face.
Bill Geary, Steve Boutte, and John Goschke are three championship-caliber modelers, just off the top of my head, who have pointed out inaccuracies in kits and then gone on to obliterate any trace of the problems they point out. They expose the "kit assembler" angle for the mockery it is, and something tells me they're not the only three on the face of the planet.
