With the Wood Threading Kit—which offers precision cutters—you can make short work of cutting both inside and outside threads, though a few precautions are in order.

Anybody who collects antiques knows of the myriad of applications that old world woodworkers found for threaded dowels (see “Best Applications” on page 69). The large, coarse threads offer remarkable holding power and an astonishing degree of torque. And now, with the Wood Threading Kit—which offers precision cutters—you can make short work of cutting both inside and outside threads, though a few precautions are in order.

    Oil soak is critical

    I bought the 1 1/2. Drilled my 1 3/8 holes (white oak) cut my dowel into 3 12” pieces (maple) then soaked submerged in mineral oil for over 3 days. Cleaned them off and took my time and it worked terrific. Tried threading a hole that hadn’t soaked in oil and had a lot of tear out. Too bad ya can’t post pics here.

    learn to use this tool

    When first tried the threads of the rod were shorter than the tapped hole. The thread box must be pushed down while in use to lengthen the thread spacing so you get the same number of threads per inch in rod and hole. Otherwise the threads bind. The thread box also needed the blade honed so it didn't tear. After adjusting it worked well and I'm happy with results

    Needed a little tweaking but Awesome!

    The one star off is due to the tweaking I had to do before it would work right. After tweaking it's definitely five stars! The dowel I received was a tiny bit oversized so it kept binding up in the entry hole. I used a scraper and trimmed down the dowel a little so it fed in easier. It still kept binding up on the way out. It took me a little fiddling to figure out that it was because the cutter wasn't protruding enough. Once I set the cutter correctly and rubbed on a nice helping of boiled linseed oil it worked like a dream! I wish they made bigger ones too.

    Works as advertised

    It does what it says! Just make sure you lubricate the tap and die with linseed oil during use. It makes a big difference!

    Off Center

    From the manual: "The hole in the removable wooden bottom is drilled to exact specifications by the factory." The opening in mine is not centered causing wider threads on one side. I used calipers to measure this. It cannot be corrected.

    Needs improvement

    When it works, it works great. The tommy bar on the tap is much too soft as a handle without wrapping it around the shaft. The cutter on the thread cutter is very low quality steel. I mangled mine on a hard spot (not a knot). I plan on making my own cutter as a replacement. With modification, this can be an outstanding tool.

    Difficult to use

    This was a disapointing product. The tap handle bent and it was very difficult to cut through maple even if well lubricated. The die was just as hard but was solidly made. Perhaps the 1 1/2 inch size is just to much to ask of this design.

    great for vice screws

    The woodthreading kit includes both the tap and die. There are many uses for a threaded wood screw. especially since you can use many different types of wood and can use it for a vice or for assembly of other wooden projects.

    just what I needed

    Product to be used for adding screw thread to hand made porcelain objects.
