Setup everything for the second op and and got them cut. Turns out I made them a little to large and they wont tighten down on the flash tube. I've reworked the model and can make some new ones that will fit correctly.
I got the larger ring machined but had a bad tool path that tore a hole in the side of it. I have it fixed now and will run a new tomorrow. I did get it far enough to know that it fits freaking perfectly.
The top row are a set I made in ~2006 and were used as the basis for my hollow cast resin EE-3s I sold back at that time.
The second row was CNC machined and sand blasted replicas of the older ones.
The next two rows are iterations on a more accurate version.
10 new 1/8" carbide 3 flute end mills showed up today. Having a brand new cutting tool vs. some random ebay used lot purchase is amazing. Going to do some sand blasting and painting as well. Check out my other thread on the split plug and stock greeblies progress.
Updated the first image with the updates to the actual parts. I've also found a way to accurately sculpt the rounded center portion. Now I've got to find a way to get in and run that on the existing ones I've made so far. Right now I'm really worried about the reliability of getting the parts indicated in the machine and not screwing up the good mounts I've made already. So far my tests have shown great promise for the end result though so I think it'll be worth the risk.
All new ones will be easy to do though, as everything will be 100% accurately indicated in by default.
