solid spar question
 
Hey, Papillon,
Sorry to have delayed, but I just checked in to answer your mast question, and you had pulled it. The question, not the mast. So if you'd still like an answer, let me know, and I promise not to delay this time.
Fair leads,
Brion

Hello Brion,

Thanks for there reply, I picked up a good suggestion on the WBF to lengthen then mortise in the step and instal a chock. I ran the numbers and it came out pretty good so this is what I did. Mast went up today

chock



This was more or less how she sat, not alot of effort to get it in line

Yay!
 
Hi again,
Great minds run in the same ruts. I was going to say that you needed to address rake, but not bend, and an adjustable step is a great way to do this (you can also play with wedge thickness in the front and back of the partners).
The big trouble with trying to crank rake away with forward tension, aside from the stress on you and the mast, is that the existing bend in your case will also impart a torque load, sooner or later; the mast would try to rotate around the bend. So you did great. And judging by the pictures, not just in this matter. Lovely!
Fair leads,

Hello Brion,

Thanks for the info. "Where all the stress goes" was my biggest concern. I realise that in sailing working the boat etc you will constantly induce loads but it seems that when ever possible you would want things to return to neutral at rest. It's very interesting that the torque will twist the stick something to keep in mind for sure.
