Download this and print it out on white paper. Tape the sheet on all 4 sides flat to a wall or door. Make sure the sheet & tripod are leveled (I used a big square ruler if that helps). Line up the bottom of your view finder to the black boxes on the sheet and adjust until the lens looks about leveled.
When testing my recent build I discovered not only was my glass misaligned by 2° but the front element wasn't flush with the step. In so many words I could see that my image was very soft & the focus was slightly shifted. So I took it apart and clean, greased, recalibrated everything. Now the image is razor sharp and clean. Need any help I can walk you thru it.
