Gary, The drill bits are 6" long. They are called aircraft drills.
Rick, Thanks for the endorsement. Gary just purchased the second to last fixture I have on the shelf.
Everyone, Thanks for your patronage. I will be ordering more material in the next week or two and working on making up a few more sets to have on hand. Right now I want to finish carving an Isaac Haines rifle I picked up a year and a half ago.
