I have a Jason scope that has a broken altitude adjustment. It uses a rod that slides through a small block that has a bolt run through it. The thumbwheel on the bolt is sheared off.

Does anyone know of any place to get replacement parts? I have seen other scopes for sale for twenty dollars or so. I want to get it fixed up to give to a great-nephew.

Moderator, of this is in the wrong forum, please let me know.

Thank you for your help.

Photos would help. Without seeing the model and design, it's hard to offer advice

Welcome Scott123.
More information about your telescope is in order.

The bolt that holds the slider on from the other side of the altitude arm should have the same thread as the knurled knob. You can take that to a good hardware store and look for a short bolt with a matching thread to replace the broken part. Some even have selections of knurled knobs (or there is always McMaster-Carr). 

 

If you take it apart, a drop of WD40 on the broken piece, applied to the inside, may help to loosen it, and it looks like there may be enough sticking out to get some vice grips onto it and back it out.

I dropped off the clamp with a friend who is handy, he believes he can remove the broken shaft from the part.

My friend was able to drill out and tap the part, I picked up a new thumbwheel at the local hardware store. So, back in business! Of course it's raining tonight. lol.gif
