Hello everyone, I decided to make the Webster 4 cycle gas engine next. After studying the plans for a few days I decided to machine the cylinder first. I had this chunk of mystery metal laying around and mounted it up in the 4 jaw.
I turned the part to 1.5 dia. then spot center drilled and used a 1/4" drill to start my hole for the bore:
I finished drilling at .625:
Then I started the boring process:
This is as far as I can recall the deepest hole I have ever had to bore. It needed to be 2.5 inches but since my bore was closed at the end I drilled to 3 inches to leave a little room for chips to gather. During the whole process I kept withdrawing the boring bar to clean the chips out.
