I want to replace the Beattie screen on my 4x5 Master Technika with a SatinSnow ground glass to see how the SatinSnow compares. Can anyone who has switched screens on a Master Technika (or, I suppose, any other model Technika) tell me whether changing from one screen to another is an easy, straight-forward operation as it has been on other cameras where I've done this or whether there are potential problems I should watch out for, any special tools that are needed, etc.?
I'm mostly concerned with just the mechanics of doing it, not with the wisdom of doing it or with possible focusing problems after it's done. I know how to check focusing after it's done and I have both screens already so it isn't a question of which to buy, I just don't want to bump into some strange Linhof/German over-engineered gizmo or design that only the factory or Marflex has to know-how and tools to handle.
I ask here first rather than just trying to do it because I'm going on a lengthy photography trip in a couple weeks. I don't want to mess things up and not be able to properly use either the Beattie or the SatinSnow screen with insufficient time before the trip to get things corrected.
