City Point Engine House Frames

I’ve been slowly starting to construct the frames for the City Point Engine House. At the top of this image is the queen post section of what will become an interior frame. At the bottom is one of end sections. First, I cut all the lumber to length. In order to get consistent results, I use an acetate sheet to hold the beams over a scale image of the framing while glueing together. The glue does not stick to the acetate which, once the glue drys, allows me to “peal” the acetate away from the wood frame.
