ETT on Engine Turning and Guilloché
The information says engine turning machines are no longer manufactured. But Tres Linnep, an ornamental turner, just told me that Lindow Machine Works created a rose engine that will do Guilloché work and they have a straight line attachment to do straight-line work. This was bought out by Columbus Machine Works for manufacture. Thus, at least the Rose engine and Straight-line machines can be made today but the Brocade machine is not.
I just found out that figure 3.5 is of a Rose Engine but set up with a high speed spindel and not a graver. If I get the corrected photo, I will post it here.
This is more to this story... apparently some digital machines are now doing work that is exactly like the older hand machines. Thus it is not clear if these new outputs would be called Guilloché or something else. This is left for further study. Any information I obtain I will post here.
Also about Guilloché - in the book I make the distinction between an engine turned pattern (no enamel) with Guilloché (turned pattern with enamel). Some engine turners I've talked with now say they make no such distinction.
Want to know more about engine turning... here is an organization for turners - Plumier Foundation. |
