steeping grain and water calculation

[kikid]

A very newbie question - am about to try my first AG brew and after entering all my data into the calculators I can see my water requirements to mash and sparge. I want to use Maris Otter and Crystal 40, one requires mashing and the other steeping. If I mash the MO for 60 min and steep the crystal separately and combine in the kettle how do I calculate my water requirements? Am I right in assuming that I can't include the crystal in the mash tun?

what size pot and how are you heating it, you can mash it all at the same time

Thanks for the reply - I didn't realize I could add the steeping grains into the main mash. This will make my life a lot easier.

you would only steep when doing an extract as a base malt and others for flavor, otherwise it all gets mashed the same way as the base grain at the same times
