And don't forget, You will be doubling the size of the model but you do not want to double the thicknesses of the material.

For example, of the original has 1/4 sq spars you do not want 1/2" sq spars because that would be four times the cross section

1/4" sq is 4/16" X4/16", =16 square1 /16" 1/2" sq, is 8/16 X8/16, 64 sq. 1/16" while doubles would be 32 sq 1/16s, so you would want 3/8" sq or 6/16 X6/16, 36 sq 1/16"

And so on through all dimensions.

Great piece on estimating wood quantities Peter, should be in the magazine
I would just add that going through the drawing creating the list is also a great way to get to know the design.

. IT WAS IN THE MAGAZINE YEARS AGO. That is the trouble with magazines, It is great for thsoe who read that issue of the mag but then it has vanaished for ever unless you get the back issue and to do that you have to know it was in the mag and which issue.

All is not lost. I am currently doing a book for first time builders and there is a chapter on estimating materials.
