M_Boats: Mast rake on M-17 plus free sheaves

I want to set the mast rake on my M-17. I have new standing rigging but need to make some major adjustments to the mast position. Do any of you more experienced sailors have some rules of thumb or specifics on setting the mast rake? Also, I have a set of four stock aluminum sheaves that Bob Eeg was kind enough to include with four slightly modified sheaves that I used for my new rope halyards. I would like to pass these four stock sheaves along to someone that can use them. Please let me know if you want them off the list at robbin.roddewig@verizon.net Thanks Robbin M-17 #056
