I forgot how to figure this problem out. if you have A beam that is 12.875 inches wide on the flange and it needs a miter cut of 37 degrees, what is the length from the end?Common sense in an uncommon degree is what the world calls wisdom.

Reply:If it was a 45 degree cut then it would be 12.875" back from the end. If you devided 12.875 by 45 then you would have the length for one degree. Multiply that by 37 and you would be good to go.

Reply:here is another example of the same problem... throw the beam in your band saw and set the cut degree to 53 degrees ( if your saw can go that far over ). if you put a square on the end and measure down the beam to the farthest point, that is the measurement I'm after.Common sense in an uncommon degree is what the world calls wisdom.
Reply:53 degrees now? not 37? it's going to be tan53 x 12.875 then. You will have removed greater than 12.875" from the now short side of the beams overall length, (instead of less than 12.875").I may still be confused as to what you mean "put a square on the end and measure down the beam to the farthest point" end and farthest point to me are kinda suggesting the same thing. Just draw it in paint, or use standardized geometry nomenclature to describe it.Last edited by MikeGyver; 08-17-2011 at 12:05 AM.Welding/Fab Pics: www.UtahWeld.com
Reply:sorry.I'm on my Android at work. after the beam is cut, put the square on the tip of the cut and measure back square to the other end of the cut. based on your formula, is it about 17 1/16" ?Common sense in an uncommon degree is what the world calls wisdom.
