0.96" - 1.25" TELESCOPE ADAPTER
One of my Ebay customers required an adapter for a telescope video camera he purchased from me. I know you can buy these adapters but I offered to make him one instead. Being a newby engineer I needed all the practice I could get.
Outcomes: I learned that I need to purchase a boring bar set. You don't want to know how I managed to bore out the job.
First you load up the lazy man's hacksaw. I did not have any round stock. |
Then you turn it on and let it cut,cut,cut..yawn, cut, yawn some more and finish 10 minutes later |
Now because it is a squarish piece you have to use your 4 jaw chuck. This was my first time ever using the 4 jaw chucky. It was pretty easy to centre it. |
I set the lathe to 600 RPM and donned the safety gear. I hope I did the right thing. Anyway, after a few cuts I was turning a square into a squircle. |
Wow, a few cuts later my squircle became a circle. So far so good. There was a lot of swarfy stuff all over the floor. I messed up the workshop bad.
|
Now I had to drill a hole in the centre so that I could start boring out a hole that would be .96". This hole would take the video camera lens.
|
Now with the centre bored out it was time to put a colar on the outside as well as seat on the inside. |
The seat will accomodate the collar of the camera lens to enable a snug fit. |
Het presto it's finished. The 0.96" lens is on the left, the adapter on the right. The lens screws into the TV camera. |
Here you have the lens fitted to the adapter. I allowed a 0.6mm clearance for the adapter so it is easily fitted to the scope eyepiece. |
