I apologies for going off on your suggestion and blog spot. You offered a constructive suggestion and I only saw the down side to visitors in terms of the ads.
While learning a new woodworking techinique/method I often put together instructions for myself. As an amateur/hobbyist/addict, I tend to jump around the woodworking realm and not get back to a technique for months or years. The notes/instructions to myself shorten the relearning curve later. My hope is that these notes/instructions can shorten the newbie's learning curve and get someone to try what he/she thought was too complicated or difficultt to even attempt.
To that end, I'm trying to come up with a way of visualizing what, for a given pair of end centers, is the "solid/common" shape,the "shadow shape" and the "null point" of an eccentric pair of centers.
My first approach was too ambitious. I'm now workingjust on how the "null point" moves down the blank as pairs of centers on the diagonal of the ends changes. IF I get someothing that makes sense to me I'll put it up on my site - space permitting.
This turning thing is complicated - pat your head, rub your stomach, jump on one foot, AND whistle- ALL at the same time. Throw in sharp cutting edges that you roll and/or swing and things get really interesting - and fun!
