I'm one of those old skoolers who would rather have something come out a 7 or 8 out of 10 and be done 100% by myself, as opposed to farming even part of it out, even if it is a surefire 10 of 10.
I don't learn, or gain any experience, when someone else does the work or uses tools I don't have or have access to.
When it comes to boring deep passages . . . . in acrylic . . .
The trick I have found, besides the experience of feeling when the bit is near to galling and pulling out in time, is to have a spray bottle of lubricant water to cool the bit frequently and lubricate the bore.
