Late Mar 2020 building the female jig

the jig needs to be split to remove the hull, hence the reason they are cut in port/starboard, so I joined them with a fisher plate & screws. Then I cut longitudinal spacers on a drop saw out of of mdf I ripped into strips on a table saw when I milled the ribband. when I screwed the jig to the table I made sure to put the screws where I could back them out when ready to split the jig & used a spinning laser down the centreline.

The ribands fit in the notches perfectly & the keel line timber was made wide to make templating & construction easier. The only pain in arse bit was the hardware not having 19x19 for the ribands so I milled them on a table saw.

The sheer line riband I have to notch forward of the chainplates (aft the sit on top of the station frames with a slight notch to facilitate the topside angle required) & I have decided to continue them all the way to the transom & build the winglet mould on top of them. Because I did thi the sheer line is higher then designed at the chainplates by a few mm & at the stem by 15mm.

When I screwed the ribands in place I only did the port side of the keel timber so I could still split the mould
