@verbotenwhisky - check out "Inheritance Machining" on the youtubes. He build a D1-x mount for his rotary table. It's pretty cool that he can just move his chuck from lathe to rotary table without upsetting the part in the chuck. I'm that project is a little more than I'm willing to invest time/skills wise right now.
I rarely use the ER40 chuck.. but have a full set of imperial/metric collets. I also had a botched backplate from something else I could make fit this.. so I'll get centered up and pretty much live full time on the rotary. I use it as an indexer more than anything.
Ultimately I'd like to get a Shars "set-tru" type 6 inch 3 jaw, and build a back plate that indexes in the rotary table's MT2 mount. This was just something I tossed together with stuff I had until the chuck is in stock.
