Thanks to the OP and all of the FineScale members who responded, I have returned to more regular modelling after nearly a month of "model funk". The problem, as it usually is with me, is the need for perfection, which always sabotages satisfaction. It was beginning to seem that every time I sat down to work on a current build, I'd make a dumb mistake, which would often lead to several minutes to a few hours to correct, if they could be corrected. But I have to admit that I've worked "smarter" with each new model, and I am making fewer and less-problematic errors. I'm a long way from a winning entry in a model show, but that doesn't bother me as much now as it did, thanks to this thread. Bob
