I could use a little help building my bow end form for a Great Auk. In the picture, how do I attach the side form as positioned to the bow end form? Do I cut out the middle portion of form 1 and glue the sides to the end form, or is it better to notch a section from each and slide it on? Do I position the side form to line 2 or line 3 in the picture? Finally, I will cut off the dotted section of the form to use as a template for my internal stem, but am I supposed to remove the dotted section along line 1 too? Thanks a ton for your help....its my first time. I finally finished attaching and aligning the middle forms to my strongback...what a job!
