Lee Valley Stainless-Steel Drawbore Pin, 3/8" Pegs

Stainless-steel drawbore pin for 3/8" pegs.

Drawboring is a joinery technique that produces strong, durable joints without need for glue or clamps. The key to making a tight joint this way is to offset the peg holes by 1/16" to 3/32" between the mortise and tenon, so as a wooden peg is inserted, the joint is drawn together. Ensuring proper alignment before final assembly can be tricky. This is where a drawbore pin is useful. Its tapered shaft acts as a wedge, drawing the joint together just as a wooden peg would, allowing a test fit prior to assembly. It also partially aligns the offset holes, helping clear the way for the wooden peg that will ultimately secure the joint.

This pin is 12" long overall, with a 7 7/8" shaft that tapers to a point from a 7/16" diameter base. The turned stainless-steel shaft runs the length of the tool, and the octagonal bubinga handle is epoxied in place for strength. Also available for 1/4" pegs.
