Yep, I did the same! I used my coax indicator on the 3 sides. It is still a casting, so the best you can do is a few thou, but it is at least it is a nicer casting than the inside.When I made my #5 I centered the cylinder bore using the outside of the casting.
I hope you didn't turn it on. Good idea.I used my coax indicator on the 3 sides
Thank you Lo-Fi, I hope I get good results when I go to assemble the components.Just had a nose right through your album. Some lovely setup and measuring/marking work right there!
