[quote=MN3][quote] I was wondering if anyone had made a spin pole from a carbon fiber windsurf mast[/quote]
Close:
i have had fiberglass spin poles made from windsurfer mast
I have had 4 different alum sized bow sprits (2 f18 sizes, 1 Tornado sized, 1 a few inches longer than T sized)
i currently have a CF windsurf mast rigged identical to a spin pole but cut shorter to hang a small front tramp off of and to secure a turning block under my furler for "on the fly jib luff control"
so i have some insight but not exactly what you requested.
my thoughts:
alum poles are very cheap - probably the easy solution e.g. $100 ish
my fiberglass spin pole worked fine but had a good deal of flex. if i recall i snapped it in a capsize when somehow my foot used it to stand on
when i cut down my cf pole i used the top 1/2 since i didn't care about flex
if it was me: i would purchase a new alum pole to reduce flex - but if you have the cf mast and want to try i would use the thicker part for the same reason
since you don't have a standard bridal, you have less attachment places (i think) to secure and restrain the pole and therefore would have even more flex than any other cat that doesn't have twin halyards (assuming your setup is stock)
not only will the flex affect luff tension of your spin/code ... but will exacerbate the worming out of the holes you have to drill to attach the hardware to secure it to the beam.
one more suggestion: CF and salt water don't mix. if you sail in salt... i highly recommend you get synthetic spacers/washers of some kind to seperate all metal (bolts/nuts). I also liberally applied tef-gel and still have rust

spacer reference (also done inside the beam)
