Have those. Loathe to take it to rigid plastic.I think they are known as "Aviation shears". They come in straight cut, left cut, right cut models. View attachment 119062
Already butchered one set of these.You could always do it like the shop would - a pair of curved snips. Rough enough is good enough. 😄
This is a good idea.If you used this method, you would want to screw the part to the wood using some self tapping screws around the periphery of the waste piece.
What’s an air belt finisher? I asked a metal shop if they could do it. No dice. Also couldn’t suggests a tool. Then I asked here and voila! Thanks all for the adviceIt’s comical reading all these ideas and it shows virtually no one actually works with tools these days! 🙄 Proper tool would be an air belt linisher as you have perfect control and it puts a perfect curve in. Failing that and you could heat up a knackered screwdriver and burn the basic shape out.
