I have a Meade ETX-90/ec telescope, the verticle lock knob will not thighten. It appears to be stripped. how can I fix it? Where can I get a parts list? Thank you

The bolt is stripped away from the plastic knob-- TAKE THE vertical lock knob off and inspect the bolt head-- you can use a STRONG glue to fix it -- epoxy or something similar.

The vertical lock knob on my Meade ETX-70AT was over tightened and is broken. I contacted Meade and was told that they no longer stock this part. Looking for a source for the part.

You might be able to drill a hole through the plastic knob and use a washer and a bolt to hold the screw tight. Or do something like this fix:

I have a Orion Cassegrain spotting scope (D:90 F:500) that will not focus. The focus knob turns but nothing happens.

The small "pin" which moves the mirror inside may have either come loose or broken. You will need to remove the focuser to find out.

Visit the Mighty ETX web site for instructions on how to do this.

Can't focus

Unless you can find another "used broken" ETX of same model-- to get the focus off of-- your only recourse will be to send it back to Meade for repair--

My 96 sl 1.9 dohc valve cover gacket

The only thing would do for the stripped bolts is to retap them with a tap & die set using the next larger size. As for the one that's broken off you can use what's called an "Easyout". You drill a hole into the broken off part of the bolt and then insert the Easyout. The Easyout has left hand threads and as you turn it , it bites into the broken bolt and usually will take it right out.

Hope this helps.

Good luck Loringh
