Thread Chasers
One of the most fun processes in wood is making threads with thread chasers. Someone who is a master at this is Jan Hovens. He makes these tools in-house. They are consistently high quality. The handles are currently made of American walnut.
Stroke thread
Working with the thread chasers is a concentrated job, but also addictive! Preferably use wood with a fine grain. chasing works less well on types of wood with an open structure. Most suitable are Hornbeam, boxwood, cocobolo, mahogany, olive wood, ebony, yew. These tools can be sharpened with a CBN or diamond file. Click here. If wood breaks out ( (e.g. because the structure is not that good, or the type of wood is less suitable) you can impregnate the wood with oil in advance. Turn the wood to thickness, start chasing, stop halfway and impregnate e.g. with this oil.
If you are going to stroke for the first time, do not start with the coursest thread (3.5 mm). This is also the most difficult. Check here if there is a thread caressing course is planned.
Free running tool
To stroke a thread on the inside, a free running tool required.
Urgent
What is the thread you want to chase? You can choose 3.5 mm, 16 tpi, 12 tpi or 10 tpi in the drop-down menu. (You only choose the pitch, you determine the diameter yourself. So you can make M33 x 3.5 but also M44.5 x 3.5)
A pitch of 3.5 mm means that there is 3.5 mm from top to top. This thread is metric. A pitch of 12 tpi means 12 tips per inch, so it is approximately 2.1 mm. This wire is imperial.
