I am looking for suggestions on making a core cutter.
I was thinking something like two pieces of 1/4 or 1/2 inch flat bar. I was going to use a valve spring on the pivot bolt to provide some tension. Now should i use hardened inserts where the lead wire goes through or would just a hole through both plates work?
Im assuming that tight fit to the lead wire is better?
Here is an example of what im thinking.
