Below is a video showing how the engraved bobbins are made using a Roland EGX-360 computer controlled engraving machine.
Below is my video which is unedited, a start to finish clip of how I turn a simple shaped Midland bobbin in ebony Shot from above the lathe on a iPhone. There are many ways to turn lace bobbins and I am not suggesting mine is right, its just how I have done it for nearly 30 years turning well over 150000 bobbins! As a professional bobbin maker I use the quickest, easiest reproducible way of turning bobbins to make this my business. If you copy my method, you do so entirely at your own risk! I am turning on a modified Myford ML8 lathe at around 6000rpm. The wood I am turning is ebony and I use 3 chisels, a 1" oval skew to rough down from a 8mm square to a 5.5 to 6mm dowel. A 1/2" oval skew for shaping the bobbin and a 3/16" parting tool for shaping the neck off the bobbin, and some shaping. Sanded with 240 then 400 grit paper, then finished with a friction polish. As you can see I turn one handed, my left hand just guiding the tip of the chisel, while the bobbin is always supported while running in my fingers If you copy my method, you do so entirely at your own risk! No clothing on your arms, no ties, no rings!
In the video below I show how I make a bobbin with "jingles" (captive rings, discs of wood that move freely on the bobbin, but can not come off, all made from one block of wood)
In the video below I show how I make a mother and babe bobbin. The Motherbobin is made from ebony and the Baby bobbin is made of bone.
