Dear Paul Mateer 

  I share an A3 sized vertical tank for over 20 years with a friend, we do not use it that often nowadays sadly! 

  But I can say that a horizontal tank will only be OK for single sided boards. Double sided need a vertical tank with plently of bubbles of air to keep the etchant working on both sides at the same rate.

  I have never done it, but I would imagine it difficult to keep both sides etching at the same rate.....

  regards

  Andy

  I would think a horizontal tank would be better than a vertical one.
