How are you guys attaching to the corners of the spin? I'm envisioning the spin halyd/retrieval line tapered to 1/8" vectran or dyneema. Possibly the same for the spin sheet. Splice to a shackle? What kind of shackle? Tie on with a bowline? Other tricks?
Also, appropriate blks for the the end of the pole and the halyd blk above the hounds? I've been using Harken wire blks with 1/8" line with no problems (can't remember if it was the 1" or 1.5" blks). Will the 29 mm carbos hold up to the spin loads (rated at 330lbs)? Be nice not to have the metal blk up there banging on the carbon mast (UHMW or teflon tape?). What blks are you guys using at the main beam and tack line with the one line hoist system? Seems like they must be seeing the same loads as the pole tip and spin head.
Thanks!
