Re: stringer template
yes, post and scribe is the way to go. That or look for Lowkees bayliner thread. He did his a little different but I bet it is easy enough. I will try to explain how I did mine. I have it in my thread but it pissed me off so bad that I didnt take a lot of pictures during it.
First you want to cut your length from transom to bow or wherever they are going. Then, it helps if you left a lip of glass around where your deck used to be so you can sit the timber on top of that then at the transom, i found it helpful to make a piece of 2x4 match the angle of the hull to give you a place to set the timber on at the rear. you can see this in this photo. I also snapped a chalk line where the stringer should be so that I could follow it with the dowel and sharpie described below. I think you can see that too in the photo.
Its the one to the far left. This just sits right up against the transom so on end and gives you the finished height of the top of your stringer. Does that make sense? Then just have someone hold it in place. Take a tape measurer and find the tallest spot along the hull and get a dowel or hammer handle or whatever and tape a sharpie to it perpendicular. You now have to just run the bottom of the dowel along where the stringer is supposed to go with the sharpie against the wood. DO this from stern to bow. Then cut.
Simple if you have patience. I do not.
