Hello everyone! Installing the ribs looks simple at first, but keeping them straight and evenly spaced is more difficult that it seems. I did not glue the top part of the ribs to the inside of the hull so as to provide a bit more flexibility when I fit the deck. I hope this will help and not end up being a problem.
Thanks Dougie for the tip on those vents. I do have that reference book and you are of course correct. The kit can be improved further by rounding the ends of those vents. I can try to use my rat tail file as rokket suggested, but I think it is too large. I really need some new jeweler size files and tools - mine are ancient and badly worn.
What about that triangular shaped section of vents on top of the main group? They are not present on the kit and I was reluctant to add them. The U-99 photo does show them, but did U-45 have them? In looking more closely at the photo, I was surprised to see how small the one vent is at the stem compared to the kit. The difference is really noticeable! I think I will have to fill that vent in and drill a new, smaller, vent to better match the real thing.
Thanks again everyone, your help is much appreciated.
Bill
