Omar, that is a lot better set up than what I did. I like the swivel set up, they are asking I think 145.00 for a new swivel set up at WE. I did not put much thought into mine and only used what I had on hand at the time so it is not nearly as clean looking as this one, also I have both sides of the clamp screwed down and I think his idea of letting one side stay loose is a better idea. I have another clamp, so someday I may build another one, I would mount it to something a little heavier than what he has it on. I stand at a bench so I wanted mine closer to eye level than what he has, accounting for the height on mine, all I can say is it does work. He worries a lot about cutting himself, I think he should buy some metal mesh fish cleaning gloves.
Let us have a drink and by God lets us not think about the things we ain't never going to know about.
