I have come to the parts that I keep putting of. How does one get 6 parts exactly the same rough out all 6 to within a few tho,then go back and finish. Or.finish each operation as one on all.
Another option is to make 1 complete and use as a pattern to do the rest.
Also can you use engine oil as a cutting oil will it help. I know it’s a simple question to a engineer but to recently new shed dweller (workshop).every bit knowledge is gratefully received . Many thanks regards
