Drzeus: My degree circle was printed out on one large sheet of paper; the Altitude scale was in the middle. I had the entire sheet laminated at Staples, front & back for $2.

Then, I simply cut out the Altitude scale, affixed it w/ double-stick tape. Then I cut the Azimuth circle out (just cut the center portion up to the degrees), & again used double-stick tape to hold it in place. If you have the correct size for your base; there is no concern about error, when placing it.

I hope this helps you a little!

Just keep asking questions, believe me, I asked so many questions with this project, that it almost was embarrassing!

I admire you for going ahead with this project, you will certainly gain much benefit when complete!
