I need to cut about 15 holes from 1/2" to 3" in diameter in 1/8" increments in a 3/4" steel plate. My o/a cutting skills are fair. I may be able to borrow a plasma but I've never used one. Will I get better results with my fair o/a skill or with my first-time plasma experience?
If the edges come out rough I may have them cleaned up on a CNC mill.
My thinking is to turn a disk 3" diameter and "trace" around it with the torch or plasma, then turn the disk down to the next smaller size, repeat and so on.
I haven't found a place around here yet that will laser cut it. I'm sure that would be cheaper than having it cleaned up on a mill. Any advice would be appreciated.
