    "Hypertuned" my AVX, One question though!

    I'm sure it's not the CW shaft that's moving, it's the whole axis. I also removed the cover and the play doesn't seem to be originating from the 2 brass drive gears' it is most likely from the ring wheel and drive worm then? The weird thing is that if I adjust the spacing a bit more to reduce the slop, the motors will bind and the slop will only be reduced slightly. Is there anything else that might be causing this? I also looked at the worm gear to check if it's not tight enough (from the locking nut) but it looked fine to me. I also tightened that just in case but the issue remained. This is very frustrating I feel like throwing the AVX out the window.

    RayD would you be kind enough to check the video in this link: https://www.dropbox.com/s/dfzuzx0fkuq6b1u/1 (2).mp4?dl=0 It shows what kind of play I'm talking about. When my whole gear is setup, it really rocks side to side. I didn't get what you meant by the main problem being the main bearing. To try and remedy this, I tried tightning the worm to ring gear spacing, the worm shaft, and the motor gear to the worm gear. I also tried tightening the thrust bearing (the one on the bottom of the RA axis). Nothing worked, the play was still there but the motor was binding. I'm really frustrated. I'd appreciate if you could elaborate more and give me possible solutions Thanks so much. Anthony

    The play is lateral (from side to side). I didn't get which gears you mean. Do you mean the motor's gearbox or the Motor Gear with relation to the worm gear (the one in the image below)? If it's the gears in the image, i've adjusted them as close as they can get with some minor backlash. I don't think they can be adjusted further otherwise they will bind

    "Hypertuned" my AVX, One question though!

    Turns out that sound I was hearing was the motor housing rubbing against the RA!! Once I managed to clear that (which wasn't easy for some reason!) the sound disappeared and the axis got smoother; however I do have one more issue if you could help me with. I do seem to have a lot of free play on the RA axis. With the clutch fully tightened, holding the CW shaft and moving it slightly will produce some play in the RA (forgot to mention that while guiding I'm having periodic 5 to 8 arcsec peaks every 1 minute approx.) How can I fix that free play, is it by reducing the space between the worm gear and ring gear, tensioning the tensioner with the thrust bearing at the bottom of the RA shaft, or by tightening the lock nut that holds the worm shaft? this is very confusing Also do you think this free play is what's causing these periodic peaks in tracking or could it be smthing else? Thanks for your help!

    ah that's a good point. I can hear the same noise when moving it with my hand with the clutches released. Although I did grease the top washer you're talking about but it may have gotten loose. i will check that too. You've been very helpful!

    "Hypertuned" my AVX, One question though!

    Ah yes I got what you meant, with the tensioning thing. As for the washer issue, if I remove the washer, the ring gear will slip downwards towards the collar with time. Do you think a lot of grease will make it stick? and how good would that be

    "Hypertuned" my AVX, One question though!

    i did grease it but it probably needs a more generous amount of grease. I will try that.

    that thin ring is just a spacer for the collar since he used a different sized bearings, i got the right one so no need for that ring. As for the washer, I am using it currently but it just feels and sounds like it's rubbing on something. I did not get this part though "You adjust the tension with the retaining screwed plate at the back.". Could you elaborate more please? thanks for your help

    "Hypertuned" my AVX, One question though!

    the bearing just came with the actual tapered bearing and one ring that fits inside the RA housing. You mean to say there should be another ring that I place between the ring gear and the bearing? It does make sense since that ring would also hold the ring gear from slipping? Am i missing something

    "Hypertuned" my AVX, One question though!

    So what you're saying is that there should be a sleeve between the ring gear and the tapered bearing? I'm sorry my knowledge is very limited when it comes to this stuff. The only reason I tried to hypertune my avx is because I got a new mount and wanted to see if I can make the AVX better for my other scope.

    "Hypertuned" my AVX, One question though!

    I have no idea if I'm missing anything, I just followed that guide. There is a ring that mates with the tapered bearing which i've placed in the RA housing. It was a tight fit. So the tapered bearing mates with that ring. The ring is the one on the left in this image below.
  12. Hello, I finally had the guts to disassemble my avx, clean it, regrease it and replace it's bearings with new better ones. One of the bearings I've changed is the radial bearing; i replaced it with a tapered one just like RocketSparrow did here . I think I got everything right except I'm confused about one thing. A nylon washer was used between the old radial bearing and the ring gear. Following RocketSparrow's guide, it seems that he did not use a washer between the new tapered bearing and the ring gear. Now here's my issue with/out the washer with the new bearing: 1- If I use the washer, I can hear a sound like something's rubbing on something while slewing the mount although i did experiment with both very little grease and a more generous amount of good quality grease on the washer. 2- If I remove the washer, the axis becomes extremely smooth and exactly wha t you'd expect from a hypertune and the rubbing sound disappears; however, the ring gear starts to slip downwards (towards the bearing). So it seems to me that the washer is holding the ring gear and keeping it from slipping downwards. I've attached some images to clear this further. The images used are from RocketSparrow's website with added markings from myself. Can anyone with some experience in Hypertuning the AVX care to clear this thing up for me? should i use the washer or not? Is it fine if the ring gear slips downwards? What can i do to stop the ring gear from slipping while getting that smooth motion I got without using the washer. Any help would be appreciated. Clear Skies! Anthony

    Primary Mirror Clips

    Major Update: I removed the mirror and tightened the clips till they touched the mirror basically. Tried collimating again and the collimation didn't even budge a hair. So I guess I'll have to experiment to see how much can I loosen the clips without messing the collimation and pray that the clips don't cause any pinching... But that makes me wonder, every single post or site mentions how the clips shouldn't be tight and shouldn't be touching the mirror and that they're there just to keep the mirror from falling but that doesn;t seem to be the case here; and I wonder how many of u guys tried to do the test I've done which is to move the scope around while collimating and check what happens. I'd be interested to hear the results.

    Primary Mirror Clips

    If I use the laser with the barlow, the same thing happens but what's interesting is that the dot on the primary doesn't move when i move the scope which I think eliminates any slop in the focuser, laser, adapters... which means the primary mirror or the cell is the issue...

    The cell looks sturdy enough. It's definitely the mirror moving.
