OK, ive seen this tool once before but it was kinda small in size. It has a bunch of pins in line and you push it up to a curved object so the pins contour to the curve. Then you can take the tool and mark the pins curve on a piece of metal so when you cut it out you can match it to the curve. I want to make or find one of these but bigger so i can put a large piece of plexi up to a complex curve at an angle. Does anyone know what tool im talking about, know where i can find one, or advice on how to make one. Ive spent hours doing the trial and error method to get it to fit with some cardboard but it isnt turning out good. I just need that profile so i can cut it out.
