Thats almost exactly the way i have mine set up except i dont have the trimmer and powder on my piece of wood. All i did was mount the piece of wood to a desk. I did the clamp thing for a while but then i broke my table in half so i couldnt do that anymore. Ended up drilling it to a desk today and i've already loaded 50 22hornet rounds!
Good Luck to You and have fun
