Didn't know where to post this? I see in the down load section, plans large enough to enlarge without losing resolution. What I have done when a plan is small, is to enlarge until the lines are 1/8th wide. Then use carbon paper to transfer, drawing down the center of the lines. Using this method I have built a 4ft model from a drawing 3inches long. the proof. The second enlargement can be seen behind the model. Geoff
