Gravel screener build

[mcl fabrication]

I've began working on a gravel sifting/screener. I don't have plans or specs or have ever seen one up close. I'm building with pictures, videos and any information I can find on company website.
I am also wrestling with the idea of having it on a stationary base or on a trailer for mobility.
Since this will be my second screener build I'm attempting to do something a bit more challenging. The first one was an attempt on making a bar separator and wound up with a vibrating screen.
So here is what I have so far. And PLEASE If you have any ideas or have made one or have up close pictures please don't be shy and reply.http://
