Cutting threads in wood with a router prevents the cross-grain breakage that can occur with a thread box. Easy to set up, this is an effective thread-cutting system for dowels or custom parts.

The inserts are machined from Delrin for accuracy and longer wear. The maple base, with a steel router plate, can be clamped in a vise or mounted. The taps have a removable pilot so they can be used as bottoming taps as well.

The master kit includes the base, three sizes of inserts and matching taps for 1/2" × 8 tpi, 3/4" × 6 tpi and 1" × 6 tpi threads, and a solid carbide 3-flute 60° bit (1/4" shank). These three sizes are also available in single-sized kits that contain the same components but with only one size of insert and tap. They include plans for a tap handle and a handle for turning a dowel.

Beall has developed two larger threading sizes in 1 1/4" and 1 1/2" dia. to make bench vises, book presses, clamps, or candle stands. These two kits include the base, insert and tap, and a plan to make an adjustable stool. The carbide bit is not included in these larger-sized kits. Please order bit separately if required.
