Thread Milling Wood

1

Thought I would take a few days to learn Thread Milling by making some wooden screw caps for my wife’s sewing room. Two weeks later! Success, at least it works. Using V-Carve Pro software.

Started by buying from Magnate - 771 and a long 751 Side V Grooving bits. Price seems reasonable. Cut the bearings off (read this tip somewhere? - and the long bit was overkill.) They also have a 796 Thread cutting bit, but it does not allow you to get to the bottom of a shallow wooden cap.

A T bit cutter was needed for a little clean out just below the thread ending for the jar to seat. Overall a page full of notes, and for the threading bit only, I had to lie to the software on the material thickness.

Perhaps good for a few Christmas gifts…

Very cool! How did you get the tool path to cut down like a spiral?

Vectric has a threading toolpath.

Good to see OP made it work. I have never tried it.

I should add the bit had to be carefully measured and created in the tool data base.
The rounded edges of the cap was done by hand on a router table.
Also, a jig was made using external threads.
Retired, enjoyed the learning process!
