    Hi all!

    I'm trying to build my own boat. I found this free plans (attached .zip-file) but I have a question about the marking gauge. I do not understand how I have to use it to mark the stocks for the frames. I kept reading it over and over again but I just can't figure it out!

    Can someone please help me? The gauge is mentioned in page 3 of the plans. I marked the paragraph.

    Cheers!

    As it says under FRAMES the first thing you do is you draw full scale patterns of each frame. Then you lay down a piece of wood on the pattern and lay the marking gauge on the pattern also, as shown. All the gauge does is elevate the top piece (the straightedge) of the gauge so it lies flat upon the frame piece to be marked. Otherwise you would have to prop up the straight edge with a scrap of wood and line it up with the pattern by eye, which would be prone to inaccuracy.

    Where it says 'Side Members-Mark and Cut Each Frame', I would turn the gauge 180 degrees around and lay it on the actual pattern and then mark the end of the side frame piece. As it is shown defeats its purpose, as you have to eyeball its alignment with the pattern.

    As always, accuracy from the start pays off all along the build until the very end. To make an accurate gauge, make sure the sides of the gauge are at 90 degrees to the bottom and that the two pieces are parallel. The best way to do it would be to make it a little wide and then rip the sides down to size on a table saw.

    Does that help?
