Jaegers 6" f/10 "GJD" OTA Construction - Main Tube Prep (drill holes for focuser backplate - 2)

 

1/8-inch final sized holes drilled in Main Tube to receive the Focuser Backplate - 2 (Click to see an enlarged image.)

 

Going to the second drill bit, here is a photo of the main tube displaying the slightly larger 1/8" bit that I used to increase the hole size from 1/16" for connecting the focuser backplate to the main tube. The next bit will be 1/4" in diameter, but unfortunately I did not take a photo of it after drilling. Nevertheless, I believe everyone will get the message and understanding of the process.

With this stpe done, let's get the focuser backplate ready for alignment and test fit onto the main tube.
