The laminated wood top for my new woodworking bench is coming along well (but slowly).
In preparation for eventually joining the legs of the workbench to the top, I made myself a set of drawboring pins this weekend. I intend to experiment with drawboring these joints for maximum strength and durability.
My drawbore pins are based on Chris Schwarz’s “Drawboring Resurrected” article on the WKFinetools website here:
As Chris recommended, I bought a cheap set of “alignment tools” from Sears. Sears sells an
eight-piece set of punches and alignment tools under its “Companion” brand ($6 total). Two of the eight tools are alignment pins that can be modified into drawbore pines. The model number of the set was
I followed the directions in the article, and using some scrap mahogany from the desk project, I came up with these:
One small and one large. Slight tapered and hex handles to make it easier to “torque” the tools when using them.
I’ll try them out on the workbench in a week or two.
