Center finder for drilling or marking on boards
Description
Center guide for drilling 8mm (5/16") holes or marking center lines using a standard #2 pencil. Outer pegs can be moved to any of three holes to adjust for board width up to 6" (there is no minimum width). Can be used with or without two 608 (generic skateboard) bearings. Hole is 22mm (7/8") wide without a bearing. Using a bearing enables perfectly perpendicular holes, perfect for doweling or making floating shelves (the reason I made it). If you don't like the pegs (which fit snugly), you can use 3/8" bolts instead (they should thread in nice and tight). Let me know if you need any changes or have ideas to improve it.
