Darwin, no umbrage is taken at all; how exactly DOES Grandma suck eggs? :lol:
You're right, that was exactly my question/concern, that the difference in the base piece would end up multiplied as Rob went on in the build (but, of course, we are talking about Rob, not a newbie like me, and he caught it from the outset

). This type of problem would be something I would have cursed up a storm over as I tried to lay the deck and she took on a ski-jump front instead of the beautiful bow she is supposed to have! :lol:
Truth be known, I probably would have caught on when I laid the framing and found the problem, but it shows how vitally important it is to test fit everything before gluing in place and I surmised a fitting problem like this could require a major re-sizing of the rest of the parts to make sure they all fit; sure, a basic building technique, but it does show how a fitting problem can come up even with a kit from an otherwise outstanding commercial publisher. A great lesson for all of us newbies, I think.
There are a lot of old, out of production GPM kits going into the market on eBay these days and I wonder how many could possibly have similar fitting problems. There are some, like this kit, of ships not otherwise available today, and it's surprising, at least to me, that such a complex kit would have a fitting problem of this magnitude on something as basic as the base (maybe other areas too, I suppose), particularly when we are talking about a problem with the original printing.
Rob, just so I understand your checking method, you measured the waterline/base and compared it to the Maurice drawings (worked out to scale, of course) and found the measurement off? I was wondering whether the increased and corrected length of the base piece might also affect how the central former lines up with the corresponding placement of the thwartship formers when compared it to the original piece. If you added 2.5 cm to the base, did you find the original formers were also short or was it the correct size; was it only the base that was off or did you have to adjust the remaining pieces of the framing? Also, was the problem a length problem or did you have to make other adjustments (width, not just the length) to make everything fit properly? Have you discovered whether or not the deck pieces are a bit off too, or are they of the correct length now that the base is re-sized? I gather you tried to rescale the base piece to increase to the correct length, but still found it was off; I suppose my very basic question is what exactly did you have to do to arrive at the correct base piece re-scaling using Maurice's drawings, and whether you did something else to the remaining pieces (thwartship formers and profile former) to get them to all fit properly?
Sorry about all the questions, guys, but I have been fortunate in my limited experience to not come across such a problem and would like to know how the experienced fellows go about detecting the problem and what steps are taken to ensure a correct fit to the rest of the kit.
One additional thing this experience shows is how helpful it is to scan your kit, even a commercially published kit, before building so that such adjustments can be made. I don't want to belabor the lesson here or to go off on a tangent on this thread, but, if possible, a further, short explanation of what exactly you did, Rob, would be very informative to the less experienced fellows out there, like me, I believe.
Okay, the newbie student now puts his hand down awaiting the lessons from the teacher.
