Jim Stumpf Posted February 11, 2012 Posted February 11, 2012 Been slowly making some progress on my CS. The two mast are just about complete, the birds mouth sprits have been rounded and plugged and pins turned and glued into the sprits. The mast were primed with Sherwin Williams Auto self etching primer, then top coated with Rustoleum primer and the Rustoleum paint. Seems to have bonded pretty well, time and use will tell. The sprits have been coated with 2 coats of epoxy and then will be varnished. I've made up a second mast step tube for the third mast step today, I will pop that off of the mandrel and fit it out. Blowing like a mother out there today plenty of cold and snow. I may have one more cup of hot coffee before I head back out to the shop, enjoy. Quote
ecgossett Posted February 13, 2012 Posted February 13, 2012 what kind of wood? What dimensions did you use on the wood? Quote
Jim Stumpf Posted February 13, 2012 Author Posted February 13, 2012 what kind of wood? What dimensions did you use on the wood? Hey Ed, The wood is cedar and the plugs and pins are southern yellow. The diameter of the sprits are 1 1/2", I will have to double check the thickness of the staves. That being said I am not sure that the effort put into birds-mouth sprits is warranted for this application. The Cleveland Amateur Boat Building Society put on a birds mouth clinic in my shop last winter (pictures are at the link in my signature below) we built the two sprits just as an exercise. I think the solid/square sprits by Graham probably make the most sense. As for the cedar that we used, the same stock was used a couple of years ago for the mast and gaff on a Green Island 15 and has handled the loads well. Thanks, Jim Quote
