I didn't tell him not to, I said I would not SUGGEST doing that. After reading his OP, I don't think has been building kits since he was 12, or scratch building for that matter. I could be wrong. That being the case, scratch building a RH is NOT something you just jump into. Even a RH kit from Korber, Brennan, or Altoona is not an easy kit, and all the parts are provided for you. You better be a pretty experienced modeler to tackle a scratch built RH.
And for the record, I have nothing against the Korber RH at all. It happened to be a matter of timing when Dennis announced his kit, and we were shopping for one. I wanted something different, that's all.
