Redirected Efforts

Still without transportation with enough capacity to run parts and tools over to my daughter's. But rather than lose the weekend time I am actually working on the list of things still needed...

I lofted and cut out the bottom panels today. Read the plans, set out a center line by taking the widest dimension from the drawing, adding 20mm to that and rounding up to the next "unit of 10." Came up with 530mm. I drew the center line 530mm from one edge of the plywood sheet.

A table (done in OpenOffice spreadsheet) helped me mark off the dimensions:

Centerline
530 0 530 0 530
609 79 530 79 451
685 155 530 155 375
755 225 530 225 305
819 289 530 289 241
875 345 530 345 185
923 393 530 393 137
963 433 530 433 97
995 465 530 465 65
1018 488 530 488 42
1033 503 530 503 27
1039 509 530 509 21
1034 504 530 504 26
1017 487 530 487 43
989 459 530 459 71
948 418 530 418 112
923 393 530 393 137

Too bad the table format didn't copy. The center line dimension is in the middle column. The dimensions from the plans are listed in the two adjacent columns. I subtracted the dimension from 530 to get the measurement from the edge of the ply for the one side, and added the dimension to 530 for the measurement for the other side. I double checked these dimensions and measurements several times. Once I had marked the ply, I checked again.

I faired in the lines by "connecting the dots" with a long thin ply cutoff from cutting the side panels. When the lines were drawn, I cut out the panels using the pull saw.

Next step will be to mark the bulkhead and center case positions, tape off those positions, and epoxy the inside.

The bulkhead notches have been cut. I used a cross section from the chine-log stock and, remarkably, the notches match the dimensions listed in the plans!

The chine-logs have been cleaned up. The paired pieces have been planed to match and the primer has been sanded off. The scarf joins have been touched up and I am now happy with how they fit.

While working on those scarf joins I thought to check the sides of the stem. It must be my planing technique as there was a crown on each side of the stem. Removing the crowns provides a nice flat surface for the hull panels -I checked it with plywood. With the crowns on the stem, the ply rocked a bit and there were gaps between the stem and ply. After the touch up, the ply lays flat and there are no gaps.

The ROS is doing a fine job in smoothing the foils. The paint I am using is not high-gloss but the surface will be smooth!
