Yep. Exactly. Unfortunately, now, "everybody knows" that it takes "thousands of hours" of sanding. It's become "group knowledge." You see it pop up here on HBA every time someone mentions a moldless project, and we have to go through the same arguments and examples over and over to show that what you've described is the actual reality.Topaz, you're right about some people thinking (thousands of hours of sanding). I've built two Long EZ's and the actual hours of sanding is closer to 250. It just SEEMS like thousands of hours because it's the only part of building a moldless composite airplane that isn't interesting and fun.
Can you spend thousands of hours sanding and filling a moldless composite airframe? Have some people done it? Sure. Don't pay attention to core shapes from the first cut, pause during a hot-wire cut and put a gouge in your core, don't pay attention to peel-ply'ing overlaps and joints - just "get on with it and worry about finishing later." That'll get you into "thousands of hours" of sanding very quickly. If, on the other hand, you worry about fit, finish, and shape from the very first hot-wire cut, the actual "finishing" is hugely reduced.
