So, now Rob gets to make another bracket for the valve and handle
Oh, great!
Thanks guys for looking at Loretta's project. We are having a lot of fun getting her tractor in shape.

In boring holes, I use a boring head like a Criterion for example. The bits are carbide tipped single lip cutters sort of like a lathe bit. These are round shanks though and you put them into the boring head. You move out the boring head a little at a time to bore the hole larger with each pass. It's very accurate and keeps the hole dead on center of your quill.
I do dry cut and drill a lot. I use air which blows a constant stream onto the tip of my cutters. Cutting oil is the most preferred or coolant, but it makes a bit of a mess. So I use air. I can also shoot the chips into a direction away from me too. If you control the speeds and feeds, the good quality cutters and drills last a long time too. I always resharpen my own bits before each job though, so I know they are sharp to begin with.
