Update on the ModelCraft Centurion:
It took the better part of the weekend to get anything substantial done on the turret, and that's all that I've been working on. First, the top portion of the turret would not allign properly with the bottom two halves, so that needed to be sanded all the way around. Done. I ended up fiddling around with the barell to get some decent result, as it's impractical to replace the thing.
Two fairly big inaccuracies with the turret mounted storage bins. The left side of the turret has two of them, spaced on either side of the escape hatch. However, the forward most one was too large by about 3mm, as it was halfway over the hatch. Some cutting, sheet styrene, and white putty fixed that. Similar problem was found on the right side turret bin, the large one. It was too large again, and the clearance between bin and smoke discharger mount was inadequate. Again, cutting, styrene, putty, and the problem was, after a long while, fixed. Then it was on to replacing all the grab-handles on the turret, and this being the first time I had to make so many, it was quite a lengthy task.
All in all, the turret is still not finished, as I still have to mount the smoke dischargers and some small details.
So far I'm loving this. It's the first time I've ever tried to scratchbuild/improve on a kit, and I'm loving it. It definitely prolongs the construction by a fairly large amount, but the construction is what I love the best.
