1" to 10 mm boring bar adapter

In Needing to cut an internal snap ring grove in a .625" bore I discovered that I still hadn't gotten around to making a boring bar adapter for 10mm boring bars. Since this bar is 6" long I wanted to use the BXA#4 250-204 1" bore tool holder, as I have a few of these bars in varying insert configurations I also have a couple of 3/8" bars I was hoping the bushing would be able to squeeze down to hold them as well,
Here is what I did I started with 1" 1018 cr round drilled it to 10 mm set up my change table to make my band saw a vertical saw then cut 3 groves part way through the length of it and one all the way through the length of 1 side
