OK, here is second part. Before I proceed to a 3rd part I decided to post detailed pictures of my setup. Here is entire adapter disassembled in parts. this will show how simple (or complicated) is to build this. Main benefit of this setup is that you have compact, lightweight, practical and good looking adapter with high quality picture. This is simplest setup of my adapter. There is a lot of room for improvement or upgrade, like downside rod system for mattebox and accessories like additional power supply, XLR adapter, wireless mic, shoulder support, front handle and follow focus in terms of functionality, in terms of good looking all parts has to be powder coated to look fully pro (except bars that has to be anodized in white, on black stays marks from usage), in terms of high quality picture to use higher quality UV filters and GG or achromat.
So, first please everybody who is intrested in this setup take a good look at this pictures because it will be much easier to explain how to build this. There is couple of parts that has to be done at CNC shop and this is mayor problem for DIY this setup, but you can always buy your self a rail system that already has that part and save a lot time.
15mm rods are solid aluminum bars from my metal depot wholesale and 3m cost around 25$. They are heavy but very rigid. This is usualy second problem. Thats why I recommend to buy something like this:

They have exellent free CAD drawing software, so you can order things for you or find how much cost something without even asking them. Their software you can also use for other stuff... They are not cheap for one or two parts but for 10-20pc are ok. You can also try to find localy a shop that can do this couple of things for you. (Even big guys doo that...) Ask them to do only hard machining part, holes and threads and painting you can do yourself. Clamp for 15mm rods like mine without fine finishing and without holes and threads cost around 15$/pc in a shop where I do my stuff. Please don't ask me to do this for you. If there is enough interest I will post plans with measures for rod clamp without threads.
