Made this sequence to help me decode this thread. Don't know if it helps anyone yet, not even sure it helps myself. Anyway here it is.
I did not have the tools to make the line appear in the exact same place in all images. My idea was to make what I beleive is the "turned shoulder plane line".
NOW I will go on with the reading.
Fredrik, my "bash" buddy.
Nicely done!
If you have the energy or the time, please draw a few more lines. When drawing your lines, please reference the book pics as close as possible. Note that we are referencing clubShaft control. Draw a line up the shaft at address. Draw a second line like 10-6-b and please note where it bisects the arm pit. Third line shoulder tip area. Upon completion, have a plane party.
Got further questions, please contact Henning or I because if you recall, we wore this out.
