changing potentiomter range

[CodeMonk]

I could have sworn I saw something  similar to this before, but I searched with no luck.
Is there a way to take say, a 1M pot and change its range to do say, 400k - 800k?

Oh...I just thought of a way, add a beginning and an ending stop inside the shell.
although I would still like to see if there is another way.

Thanks

if you take a 1M resistor and put it between lug 1 and 3 you'll get a 500K pot, so just test a few resistor to get to the range you want, like 1M5 or 800K...and put the meter on lug 1 and 3 and you'll see how much the pot is....

Sorry, maybe I wasn't clear.
With a 1M pot, fully counterclockwise you are at 0 ohms, fully clockwise, you are at 1Meg
What I am trying to do is fully counterclockwise you are at 400k ohms, fully clockwise, you are at 800k

Thats a handy link there selectortone.

Put a 400k resistor in series with the 1M pot, and a ~333k resistor across lugs 1 and 3 of the pot.

  You need a circuit consisting of a 400k stop resistance in series with a 400k pot [ a pot that measures 400k.
  resistances in series: add.
