Mike: Mike Shanks and I built a POF model of the Armed Virginia Sloop by Lauck Street Shipyards. It uses the technique I described to build the frames. I've started a 1/24 scale Triton cross section and a POF Fair American so I've had a little experience with building frames.
I see that you are off to a very fine start on your HMS Blandford Cross Section. Very nice woodwork you produced with seemingly little effort on your behalf, WELL DONE. You sure seem to be a pro at this kind of a build. I have not yet started my cross section build as yet but by looking over your build log you have given me a lot of very fine pointers that should be a great help to me when I do get started, ENJOY
I'm getting ready to notch the keel to accept the frames. The plans call for the keel notches to be substantially wider than the frames - at least 1/16"!! Do I try to cut the notches to fit tightly around the frames, or clean out the whole area and worry about setting up the frames properly in the oversized notches late?
What about the first and last frames They should sit flush with the ends of the keel fore and aft , right? The station lines are printed on the keel plans so it should be no big deal to draw new notches.
Hallo Dave, on the photo it is looking like, that the floor timber of the frame is reduced in the thickness.
Seems, that this is the reason why the frame is smaller than the score in the keel. Can this be?
Mike: The notches seem to fit much better in the revised keel drawing, but the keel length is 1/16" shorter than the previous keel, the building jig or any of the other drawings based on keel length. The old keel (and the deck length in other drawings as well as the jig) was 7-27/32" long. The revised keel is 7-25/32" long.
Thanks, Mike! You are probably right. What I did was copy the .pdf page showing the keel by 101 %. Since the change of 1% is small in the long dimension, it is insignificant in changing the height. The result was that the new template matched my keel length and building board dimensions.
I don't think I need change to building jig , Mike. By enlarging the revised keel drawing to 101%, the drawing has the same dimension as the jig in length, but didn't increase in height significantly at all. I think I'm good!
