I bought a beat up 6ft acrylic tank to be used as my sump. It has an inner wall that I noticed is bowed and un even. I bought 5 acrylic sheets (1/4 inch) and will need to cut them to fit. Can anyone suggest a way to measure and transfer the measurements from the sump to the acrylic panels. I imagine there must be a way to scribe, but can't figure it out. Measuring with a tape wont work because of the bowing.
Thanks
