Mount Woes
« on: January 16, 2014, 06:21:48 PM »
Well I managed to put my NEQ6 out of action before I got the chance to properly test the belt mod :( as the mount was altered for packing I needed to adjust the alt screw quite a bit. Being wary I made sure the mount was under no stress while I did the main adjustment and during set up and polar align I was about 1" low so I turned the alt screw a few time but nothing happened. So I turned it again only to get that sinking feeling when you know something is badly wrong. You guessed it the alt screw had skidded of the peg inside the casting :(  ( just like Jeff's)

Groan!! So it's out of action until I get yet another mod done. For those that haven't heard about it there is a guy on SGL called Gunnar and he has developed a neat fix. It's an aircraft grade aluminium block with a hard steel insert which bolts to the casting and gives the alt screw a ball socket to locate in. This makes adjustment silky smooth especially if you take the time to adjust and clean and re grease the spacers either side of the  main bolt. Yes you have to split the casting for this mod!!!!

The risky part is easing off the plastic side panels with the logo and engraved scale. These are easy to break I'm told

Well the Gunnar part is on order and I'm trying to psych myself up to remove the side panels this weekend. Wish me Luck please :)

I removed the side panels from my old EQ6, one popped off no problem, the other was a nightmare and cracked, There appeared to be no difference in the amount of glue used, I guess it's down to luck!!  :o

I feel your pain Tom, I remember how I felt when it happened to me! :(

The annoying thing is that considering it costs nearly £1000, such a vital part shouldn't be failing. Unfortunately though, in order to keep the mount at under a grand, some things have been sacrificed.

I've thought about welding something stronger over it myself so this idea could be a good one. I hope all goes well, I'll be keeping my fingers crossed! :)

Its made of crappy cast white metal, fairly sure it cant be welded Jeff. How's the gunner mod fitted?

Cheers guys

The Gunnar Mod is screwed to the face of the peg on the casting where the Alt screw strikes it. I'll post some photos when I do it

I though the side plates were plastic!!! If it's that cheap metal they use for the Chinese equivalent of dinky toys it's awful stuff with the strength of cheese :(

I am having mount problems myself so I feel your pain too. Luckily it is still under warranty and FLO are taking the head and handset back for sending to Celestron for checking and repair. I have been using the AVX for 6 months without any issues (except my ineptness at operating an equatorial!). When I tried to set it up for an astronomy talk and demo at the local school it stopped working giving a "Invalid Model, No Response 16 & 17" error message. Seemingly it is not an uncommon fault and relates to either power, connections, firmware or motor board problems. I followed Celestron's diagnostic checklist and it seems my luck was out, as the fault appears to be a blown motor board which is the only fault unable to be corrected without sending it back. I must admit, however, FLO were great and they are picking up the mount head and handset on Monday. I am hoping for a quick repair.

I'm also having some issues with my mount. Worm gear on the dec axis has an awful lot of play in it and I can't figure out for the life of me why. I can turn the handle almost a full turn before the 'scope starts moving. Need to try opening things up to see what's going on.


I hope you get your mount problems solved.


I blame the clouds. ::)

The worm gear slop should be an easy fix, the backlash on the worm gear needs adjustment.

The Worm gear can be quite easily adjusted, you can follow the relevant section in astro babyís excellent tutorial , if you donít want to do a full strip down you can just remove the black caps (using circlip pliers) and tighten the outer ring nut which hold the bearing in place. Doing this will reduce end to end slop on the worm gear and have a dramatic effect on the backlash
