Bob Grueneberg posted a question on the Barn Door Tracker YouTube video.
You said in the talk that the full plans are available??? I'm curious where to buy the gears.
I replied.
My full build notes are here: http://computer-ease.com/darkskies/bdtwaab1.htm but please note I did not buy each individual component so I'm afraid I cannot tell you were to get the gears exactly. The starting kit came from a fellow astronomy member and the kit came with motor, motor gear, main drive gear, curved rod, some electronic bits, etc.
See my blog note http://blog.lumpydarkness.com/2014/10/reviewed-tracker-parts.html for more details and a photo.
This is all based on Gary Seronik's design... But I would think any hobby store would have the parts you need. Motor gear has 16 teeth; main drive has 64 teeth. That ratio is important. Gary says he got his from Stock Drive Products/Sterling Instruments. You need to drive the main gear at 1 RPM.
Hope that helps.
I noticed the hits counter is over 3400! Wow.
