This is probably a dumb question, but I've got a crown lense, a flint lense, and an objective holder for an M49 spotting scope coming my way. Is there anything special that I need to do with the crown and flint lenses as I put them together? Spacing, taping, cementing? 8)

Lee: Newport glass has an article about grinding lenses and at the bottom the last few paragraphs tell how join the lenses together.
