Hi Reg, I don't know if I can help or not  but will give it a shot. I have made a scope more or less following what I have read on here along with a little help from another member. My scope has just 3 lens in it. They are all plano-convex, ie (l. When I set mine up the lens radius on all 3 lens point to the front of the scope. If that is not the problem the only other thing that I can think of is that perhaps your erector lens is to close to the eyepiece lens. Or perhaps too close to the objective lens. As the image passes through the lens it should hit the erector lens upside down. To do that  the erector lens must be beyond the focal length of the objective lens, and thus for the image to be turned right side up, the ocular lens must also be beyond the focal length of the erector lens. My front lens is a 150 mm focal length, my erector lens is about 230 or so from the front lens, the erector lens is 60 mm fl and it about 200mm or so from the eye piece lens. This set up gives me about a 6X magnification.
I hope this helps you out.
