Do I need to cut my hull at this angle or can I just lay the bottom flat

[rudybob]

My low skill level precludes me from knowing if I should cut as I have drawn or can I lay the keel flat and save myself some cutting. It seems to me I can lay it flat but I don't know

[mtaylor]

Flat? Like flush with the bottom surface?   I don't see why not though others may have a different opinion.

Yes flush with the bottom. Thanks

If you wish to do that, then trace the outline and station lines, rotate the tracing and transfer it (or glue it) to the wood with the lower edge aligned along the edge of the wood.

There's no reason you can't rotate the side elevation so that the keel will be parallel to the edge of your block, however since the station lines will not be vertical, but slightly rotated off plumb, the length of the plan drawn on top of the block will change slightly. It should get just a tiny bit longer but, perhaps not enough to cause a significant problem.

 

Project the rotated station lines to the top of the block and across then check their spacing against these on the ship's plan.

There are two ways of drawing stations on a lines drawing.

1. Perpendicular to the waterline at which the vessel will float.

2. Perpendicular to the vessel’s keel (or more exactly the rabbit along the keel).

 

The lines drawing that you are using apparently uses a base line parallel to the waterline. This means that body plan stations are perpendicular to the waterline.  If you plan to rotate the drawing on your block of wood so that it’s lower edge runs along the block’s lower edge, then the stations must maintain this relationship.  This means that the statins must now be at an angle to the bottom of the block.  Otherwise the hull that you carve will not be accurate.  

 

I suggest that you cut it out as you have drawn it.

Which is what I decided to do because...though I need practice drawing straight lines I need practice on the bandsaw more. I do not want to draw my lines a third or is it fourth time to get them how I want. My erasing skill is quite high. It needs no more practice. Thank You :-)
