I'm tuning a chair design using what I'm learning in "By Hand and Eye". Mr. Walker shows these ratios as being "in proportion" - 1:1, 1:2, 2:3, 3:4, 3:5, 4:7, 4:5. But I can't figure out what the ratios would be after these. For example, is 5:9 in there? What about 6:7, etc. I know there is an easy and obvious way to calculate these, but just now I'm coming up stupid and I'd really like to check this chair design so I can start it tomorrow night.
Can one of you straighten me out? This has got to be right in front of me.
Thank you.
Fred
