Thank you. That was a tully great find.
I went it trough twice and it looks very good. Very well writen and exceptionally informative, I would have saved a week of resercah and buggig of taltented mechnacial designer if I had this before I started. It does conform all I was told but it is more structured and better.
Still happy about my learning curve and these are the thigs you learn only by doing and studying.
Hope this helps if another amateur like me has to fix an odd spindle.
