Dear all I would be very grateful for a bit of advice. I am building a boat that has carvel planking with 42 steam bend ribs each side. Initially during building there are some plywood frames that hold the shape until they are replaced by the ribs. I have installed almost all the ribs and only 2 temp frames remain in place. I was advised as a precaution to have some cross-spalls to avoid hull deformity and I installed a few. However, I noticed today that the sheer plank has deformed and is now a bit wavy. The photos show that in the gaps between the cross spalls and frames, the ribs are pushing the sheer plank outwards. The photos exaggerate the deformity due to lence and distance issues but it is there.It took a few days for this deformity to develop. In the plans, the next step would be to install a stringer low in the bilge and a beam self. However, I still need to do some work in the interior (sanding, floors, mast step etc). Also I need to first remove the remaining two frames which will probably lead to more deformity. 1. What will happen if I remove all frames and braces? Will the sheer plank short it self out with minimal overall deformity or will it massively deform? 2. Should I put even more braces and pul the sheer back into shape and then install the stringer and beam self? But then I will loose all access to interior. Still the beam self should add a lot of rigidity to the sheer. 3. I this what happens with all steam bend ribbed hulls? Any advice would be greatly appreciated as these are uncharted waters for me Regards Vaddoc

About the NRG
If you enjoy building ship models that are historically accurate as well as beautiful, then The Nautical Research Guild (NRG) is just right for you.
The Guild is a non-profit educational organization whose mission is to “Advance Ship Modeling Through Research”. We provide support to our members in their efforts to raise the quality of their model ships.
The Nautical Research Guild has published our world-renowned quarterly magazine, The Nautical Research Journal, since 1955. The pages of the Journal are full of articles by accomplished ship modelers who show you how they create those exquisite details on their models, and by maritime historians who show you the correct details to build. The Journal is available in both print and digital editions. Go to the NRG web site (www.thenrg.org) to download a complimentary digital copy of the Journal. The NRG also publishes plan sets, books and compilations of back issues of the Journal and the former Ships in Scale and Model Ship Builder magazines.
