After finding your Max Drift an easy way to find how much to apply is to use the "clock" system. if angle between heading and wind is greater than 60 degrees this equates to 60 minutes on a clock face and you apply Max Drift (MD), if the angle is 45 degrees = 45 mins = 3/4 round the clock face and so you apply 3/4 MD.
Similarly 30 degrees = 30mins = 1/2 MD
20degrees = 20mins =1/3 MD.etc.
To get head or Tail component take the wind/heading angle away from 90 then apply the clock in the same way to windspeed.
This is not
exact but will get you within a couple of degrees even in a strong wind. (Substitute windspeed for MD in the first part and it will give you Xwind component - handy if you are landing in a crosswind)
