I think its called a plane on a twisted

I have seen it done, but never paid any attention to it.
That is when a small board is placed on each end of a twisted board and you squat down and plan it with your eye’s, that is if I am explaining myself properly.
can any give me some info. on this, I have been building a work bench and the top is not level, I have been told by a buddy who learned his trade in Holland told me to do. But your expanded help would be appreciated.

It sounds like you understand. They are called winding sticks. You can buy them, or make them. http://www.leevalley.com/wood/page.aspx?c=2&p=53276&cat=1,43513
They are called winding sticks and they are used to check for twist (or wind) in a surface. You set one at each end of the surface and squat down, sighting across the close one and at the far one and check to see if they are parallel. It is helpful to have one dark one and one light one (makes it easier to see). What you should be paying attention to is whether one side of the far stick seems to disappear before the other. If the surface is flat (or "out of wind") the far stick will seem to disappear evenly all the way across.

For what it's worth
Thank's BigNat for you quick reply.
Now on the work bench, do keep pushing the front wind stick to see if the bench is completly flat, if the bench is not flat, then how do I find a bench mark sort of speek.

Sparky;
Sorry for the lag in my reply, All the winding sticks will tell you is that you're out of flat. It shows you which corners are high/low in comparison to one another. One strategy to get your piece out of wind is to plane a rebate on one end, taking a deeper cut on the high corner. You place the winding stick on this rebate and check it against the other one. Keep taking material off , favouring the high corner until the sticks sight parallel. You then use the rebate as your benchmark and plane the surface, again favouring the high spot until you again have a smooth surface. If your piece is severely out of flat, you can even cut a rebate as described at either end, following the same procedure and thereby have a benchmark at either end (If you don't do this, you use the previously planed surface as your reference) Doing that seems to reduce the amount of waste in a badly twisted piece.I hope this helps (It's another one of those things that's easier to demonstrate than explain).Nat
