... just don't think the plastic would turn out as well  I finally finished a project that I first decided upon about ten (or more) years ago. In the old days, damascening was done using a wooden dowel with an abrasive slurry on the end. Whenever we go to a museum and see sports & racing cars from the 20s & 30s, I always admire the details by the discerning craftsman responsible for the construction/restoration. This is my throwback to another era when the details were worth more than production output for a given days work.    |

So how did you do the job?

Quote: | So how did you do the job? | This is a very labor intensive process; even moreso than than applying polymer coatings (thermal barriers, thermal dispersants and dry film lubricants) during an engine build up.
With the piece centered on the mill's table, I started from the center and worked outward from bottom to top. Since I was using a 3/4" diameter abrasive, each strike was 3/8" (up &/or over) from the previous strike. You also have to take into account the number of strikes in the gauge openings to ensure all the rows/columns maintain alignment. Anybody care to do the math for how many strikes it took?
This project was the reason for buying the mill in the first place. It also set the parameters for minimum table travel; I wanted to be able to do the entire instrument area without having to re-rig the setup. The mill/drill I chose exceeds the x axis minimum by about 3/4".
Please note that if you ever want to pay for this process, it will be expensive...

I thought that was called "engine turning".

The practice of damascening (1585 A.D.) predates engines by nearly two hundred (200) years, though in modern terminology, it is commonly referred to as engine turned.
Try looking up damascening and engine turned (or turning) in the dictionary; my online version only comes up with one of them.
No matter what you call it, it looks cool and is damned involved to do!

OUCH. I was wondering if you did the classic way.
Sounds like a setup for CNC.
