Frame Contours Completed

After two days, I have completed transferring the frame contours to the layout board. This entailed quite a bit of time standing up or getting down on my knees while I lined up the various patterns with the measurement points. Needless to say, my legs are rather tired.

But I can now do the initial assembly and fitting of the frame parts with confidence that they will be the correct size when completed.I utilized a different approach for transferring the contours to the board. On my first attempt at this, I had used the original patterns, cutting small holes in the patterns and lining up pattern lines with lines drawn on the board.


With the new approach , I first copied the contours using tracing paper. This has several advantages over the previous approach. First off, the patterns are much easier to handle than the entire blueprint pattern which was six foot by three foot in size. The traced patterns contained only one contour on each section of tracing paper.

Another advantage was that I could easily see the measurement points on the layout board, so lining up the traced patterns was much easier, and more importantly, more accurate. The tracing paper is also a better quality paper than the blueprint paper which at times was hard to get flat. No such trouble with the tracing paper.

One final advantage was that it was easy to see where the carbon transfer paper needed to be taped in order to get the contour line transferred to the board.  The following image shows the paper taped to the tracing paper.



The next image shows the pattern lined up on the layout board. The endpoints of the frame contour are exactly lined up with the measurement points added to the board previously. The carbon transfer paper is now facing down and ready to transfer the contour lines to the layout board.



The end result after darkening the transferred lines is shown in the final image. 



So the next step will be lining up the wooden frame parts, see where any corrections to the parts need to be made, and correct them. On other parts which haven't been fitted yet, it will be necessary to trim them to match adjacent parts. And of course, there will be more floor timbers and gussets to manufacture for the remaining frames.

That's it for now.
