CSS PIONEER

Hi Nigel,
Thank you for your help.
I work in copper and brass and can use a torch.
The hull dimensions will be 1/8th scale 52-1/2" length X 6" diameter.
I plan to use copper sheets for the mid section. I may use copper tube for the conical sections and swedge them into a taper. I can also metal spin annealed copper blanks on my lathe . I can apply brass rivets.
The last 3" of the conical hull can be machined out of solid brass stock. This will allow me to press fit a bearing for the prop shaft.
I plan to use a bajonet on the rear conical section to mate up with the mid hull section with the WTC fixed to the rear conical section of the hull.
Any ideas from you would be helpful.

This is how I do it from flat plate,remember you need two of these for each cone because of the overlap,I have used the your figures,note the allowance for overlap at each edge.
regards Nigel.

Thank you!
You have made it easy.
Do you have the full-scale plate lap to lap measurements?
You see so many models with butt joints.
The original Union Navy drawings show lap joints.
Too bad the US military sent the Pioneer out for scrap in 1868!

Hi Giovanni,
the only plans I have are the ones I posted at the begining of the build log,I worked out the plate width from the line drawing as best I could,if you download the drawing in paint you can enlarge it and get a fair Idea of the size of the plates assuming that the drawing is correct,which personally I doubt but it seems to be all that is available for the pioneer.
regards Nigel.

Thank you, Nigel

My latest refit of Nigel's original design and build:
(Now with a larger piston tank, Norbert Bruggen bayonet ring, 3d printed polyurethane deck fittings  and nose-cone (flexible so kind to surface boats!) and a re-spray!)
