This jib-support part which goes into the bow of the boat has about three or four different purposes. First, it stiffens the forward deck to take the loads from the rig, second it provides a 6 mm i.d. tube for a dyneema-thread type no1 rig swivel, third it provides a 3mm wide slot for recessed steel pins for the no2 and no3 jibs, and fourth it holds a block for the sheeting system. Here I'm trying a home-made block made from a 24 mm diameter 3 mm wide acetal-wheel (yellow) which is designed to rotate around an M2 bolt through the sides of the shaped jib-support.

Lester Gilbert's PIKANTO-page has pictures of how the SAILSetc equivalent parts look like. With an RMG winch there is no need for the 1:2-gearing in the sheeting-system, and a block is placed at the very front of the boat (see SAILSetc part 67RMG).

SAILSetc has a downloadable drawing with the sheeting systems:

Jari has cnc-milled the positive moulds for this part:

Stock is a 200 mm length of 100 x 10 mm aluminium bar. There's a  2 mm hole in the moulds for the block-axle.


Next follows the negative moulds.
