WEird clutch issue?
      #6251724 - 12/13/13 09:06 PM

So I have a wedge I made and tried it out. I mounted the scope (a 6SE I bought in april) to see if the holes I drilled in the plate were right and if everything mounted right. as well as make sure the hardware is right sized. . .so I went to show a friend of mine the sun this morning. and first time I fired it up, off the wedge mind you the thing ran jittery and as if the clutch was grabbing and not. . . It did this while slewing to the alignment point. Is this normal? I don't understand what might be wrong if a wedge is a wedge is a wedge.

of it slewing? It was on the regular tripod mount when I was looking at the sun. It was running as if in two speeds kinda jittery.

and by that I mean I mounted it once, then took it off. . I wanted to make sure everything lined up right and when I went to use it not on a wedge it acted weird. . .it worked just fine every other time I used it.

I wanted pics to see if there were obstructions at all. Doesn't look like it. Are you running this with batteries? If so I would say that is the problem. Use a tank or ac adapter to give the motors more juice. These mounts, are from what I've read, notorious for needing proper juice or they just don't work right.

I have an 8 but I have not run it on a wedge or batteries.

You know, after looking at your setup, you may be getting some flexure from the plate you have under the wedge. (the horizontal one) It looks to be sagging a bit. If this gets bouncing I am sure it would cause the motors to run jittery. I would run some square tubing on the bottom side the long way. You may need longer bolts to mount to the tripod but, that should stiffen things up.

So, more power, stiffer plate.

I am not an expert but that's what I see.

no I took it off the wedge, removed the wedge, didn't run it on the wedge. Mounted it back on tripod to solar observe and it acted like it would go slow then fast and intermittent. I ran it on the power cable from outside outlet. I haven't had it a year yet and if something is going wrong I wanted to make sure I didn't destroy anything and see if it was a warranty related thing. I don't imagine the wedge being an unusual strain?

I haven't tweaked or torqued it at all, I am very careful with the equipment and how I handle it. nothing has been doped at all it was the first time it acted odd. I wanted to make sure I wasn't straining or messing it up. On a side note it was really cold here in the high desert.

Did you use the original mounting bolts to attach base to the wedge? The thickness of the wedge material seems much thinner than the original mount there allowing the bolts penetrate the base further this could have caused the bolts to contact the gear inside the base and caused misalignment or even damage Just something to investigate, the nexstar 5i mounting bolts have snap rings on the bolts to keep the bolts from being threaded to deeply into the base plus the thicker mount material.

The last time I used my 8se it was 8f outside. Although, as you said yours ran well before.

You say it is doing this even on the tripod? No wedge?

I haven't actually run it on the wedge yet.

The main bottom plate is 1/8th inch steel, and the angled is 1/16 inch the bolts are just long enough I use lock washers. It's pretty stout. (I made it at work)

The thing is I took it of and put it back on the tripod, this was the first time it acted odd. . trying to address every issue I could.

BINGO I never ran it on the wedge. I just made it the other day, mounted to see if it worked before I took it out tonight. Went to observe sun this morning, mount it up minus wedge, and it act as like the clutch is kinda sticking or maybe gears binging I dunno. But it happens when you slew it to align. So I stopped because I don't want to mess it up. Is this normal? I can't imagine a wedge causing clutch or gear problems I men it is pretty basic in function.

On the length of the mounting bolts they were a little long, but I never felt any resistance until snug. Does it not stop when running them up into it? I can add more washers to make sure I don't hit anything. I jus measured them the ones mounting the scope to the angle piece is 1 inch. I assume that's too long? I used a washer and lock washer for thickness.

I would definitely beef up the wedge though. 1/8" isn't much.

If he is right you ,may have pushed the gears in the base out of perfect contact. I hope not because you will have to open it to fix that.

I looked up in the holes where the bolts would go. I can run it around to see if I might have hit one. this might be the cause, is there a way to look at the gears to make sure I didn't mess one up? I'll add more washers to make sure I don't hit anything. seen with out the scope attached the drive is making an odd sound. . not like normal sound I don't know how to describe it.

Is it possible to see the gears of I drive it all the way around?

Just inserting and tightening the bolts to check things out on the wedge would be enough to force the large gear out of alignment even if the mount was not turned on. The problems you describe while using the mount off of the wedge makes me think that the bolts put pressure on the large gear in the base. You'll have to disassemble the base to check this out. I hope nothing was bent but the gear is thin and is held in place by a large nut and could easily have been bent.
Hope this did not occur.

You can probably handle it. The scope is still under warranty would be my concern.

well I opened it up. . the gear inside is held on by three screws. the only thing that looks odd is the drive gear. . it has a set screw inside it that doesn't look deep enough. . main gear looks fine and doesn't feel bent or appear bent. I ran the base around under power it doesn't bind up and change speeds in certain spots it does it intermittently with no real patter. . I guess that's the way to describe it its normal slew speed then slows down then speeds up. . .

That's covered under warranty yeah? I don't know if it ground on the drive gear teeth. . . How is celestron when it comes to warranty work? Did I void it by opening it?

No, I am new to Celestron. I would hope they would back their product. The opening will be an issue. Not sure if you should tell them. On the other hand, honesty has its rewards. They may be reading this thread.

Best of luck to you. Please post your results.

Hi Tyranthrax:

I've dealt with Celestron warranty issues a couple of times before and they seem pretty good about it. Opening the scope should not be a problem. The thing about Celestron's warranty service is that it is s-l-o-w.

First thing - did you order directly from Celestron? If not, you may want to contact the retailer and work through them. They may be able to provide a replacement for you. Otherwise, you'll have to pack and ship it, wait for the Celestron service to be complete, and get it shipped back. It can take several months.

-Dan

I was able to fix the issue. . .the thing I did was when I used the blots to the base from the wedge, they were too long. thank god I didn't run it that way. the drive gear, the one that is on the motor shaft is directly over a bolt hole and their bolt holes are directly below gear teeth. I'm not sure why you would design it this way, I've just worked in maintenance long enough to see it and say "what kind of moron designed this part?"

To fix it I had to loosen drive gear set screw, pull teh drive gear down and clean off the sharp points on the slave gear. It got reassembled and worked just fine. . Was a bit weird getting my first polar alignment, I'm able to do it a little faster. cord pulled out once and power wire movement killed power twice. . once AI got the new camera software installed and got the camera running the cold started to frost over all my optics. . .so I said screw it it's 1 am and I'm packing it in. . .wasn't the best seeing conditions any way. moon + slight freezing fog = bad views.

You guys nailed it on what went wrong (the long bolts) I'm gonna grab some shorter ones so I don't have to use so many washers. Anyone know the weight capacity of this mount? I guess I could get a larger scope, maybe just a this wedge is sturdy as can be. (I know there are weight restrictions on how much load the drive gears can handle)

I'm glad I could be of some help. When I saw how thin your wedge material was the problem seemed quite clear to me based on my tinkering with the older nexstar base. I have never had occasion to handle any SE scopes so could only offer an educated guess. Sure looks like you've sorted the problem out and you're right things would have been a lot worse if you had tried to run the mount on the wedge.

I have dealt with Celestron on two occasions. First, soon after I purchased the 8 SE, the finderscope would not work at all....Celestron quickly replaced and sent to me. Second, and more recently, I had a speck on the mirror so I contacted and after a few emails, they sent me an RMA with instructions. Takes approx 30 days for a cleaning\collimation. Now, I like the idea of using email as it shows the full conversation rather than over the phone and you can't remember who you spoke with this and that....Hope this help.....Best Wishes,

Gary

I actually cut bolts down to size with a rotary tool when I ran into the same issue and the bolt hit the drive gear.
With the mount off the tripod, slew until the drive gear is over one of the holes and use that to test for depth.
I made sure that the bolts didn't bottom out with no washers, then I put a washer in.
Bad design IMO.

I don't think there was a design problem on celestrons base configuration. The original bolts work fine in the mount that came with the scope. The homemade wedge changed the bolt requirements and the new design required bolt length be modified to accommodate the new base thickness. If the new base were 3 inches thick instead of 1/4 inch thick I doubt if anyone would have called the shorter than needed bolts a design issue. I think one of the issues uncovered here is how quickly we try use a guarantee to cover a self inflicted loss. It is things like this that cause companies to try to protect themselves by not covering all claims. We as responsible equipment owners and modifiers should not expect the equipment manufactures to build in safe guards for all the possible combinations we may choose to use it in.

While from what I have personally read over the years of Celestron's approach to customer service, such appears to leave room for significant improvement, I would agree entirely with Greyhaven that it would be unfair to this supplying company to attempt to hold it responsible for any mechanical/electrical/electronic variations made to its original design, by us, the end user, undertaken to further our own particular requirements.

If therefore, we choose to deviate from the original 'scope's specified intended use, of which, as result of our decision, requires known or unknown elements of re-construction, surely we, initially and ultimately, become responsible for any such variant project we alone design and thus all and any consequences associated with it ?

Just one guy's opinion,

Best regards,

I believe that greyhaven hit the nail on the head as opposed to the bolt engaging the gears. I don't believe that its Celestron's responsibility to design a product knowing full well that that someone will modify it God knows how. The product worked fine as designed and constructed. They should not have to worry about your longer bolt especially since the bolt length warning has been discussed here on this forum.

The logical path would have been to measure the actual engagement of the original fastener and try to reproduce that.

I was able to take the burs of the gears. . adjusted the drive sprocket for clearance of the drive gear so the set screw would clear. Out of principle that this was self inflicted and I have it working I'm not going to try to get free stuf ebcuase I didn't check the bolt holes. . .not to self On that one. I just figured it wouldn't have been designed that way. . .I made the mistake of assuming. Mayeb I should do an instruction on how to make one so no one messes it up.

You guys rocked on the trouble shooting, and after opening it up if this ever becomes an issue, I can always see if I can buy the gears.

I'm glad you decided to take this speed bump on the road of life as a learning experience. I did not want to discourage you or anyone from attempting modifications on their own equipment, there is nothing that can get the astronomy juices flowing quicker than some hands on tinkering. With your positive attitude and open mind I'm sure there will be many successes in your journey through our hobby.
Be Well
Grey

Glad you have decided to not try to obtain a free replacement for your own adjustments. I read a post a month or two back on one of the AP forums about a guy that fried a CCD camera because he had not put the solar filter on for a few seconds and it melted the camera. He returned it to Amazon for a free replacement because it didn't work. That is very unmoral seeing as how it was "user error" that destroyed the equipment. He learns nothing from this, and the rest of us pick up the costs in higher prices when people do that. Cloudynights has since deleted that post as he was getting irate at people chastizing him for what he did.

true, I saw the set screw marks on the large gear, looked like it had backed out, its rather far out instead of a normal gear being recessed. that's why I initially thought it might be their fault. but I couldn't move the gear and had to back it out. me hitting it with the bolt is the only logical concussion. And hat just isn't right to take advantage of them. Now their tracking is something else 3 nights in a row I can't get it to track

I dunno. I can see this "who's fault" issue from both sides.

On the one hand, Celestron sells the SE line of scopes as a turn key system, and it works as designed. It really isn't sold as a general purpose mount to placed on a variety of bases such as tripods, piers, wedges, etc. So when a user does so, he's on his own to make sure he doesn't damage anything in the process.

On the other hand, this reminds me of something that I learned in user-interface design for software. Often times a user interface provides a message or indication that user has done something wrong so he can correct it. But a far better design is one that makes it difficult or impossible for the user to do the wrong thing in the first place.

In this case, it would have been a fairly simple thing to design the base of the mount to make it impossible for this kind of error to occur in the first place. The fact that this kind of serious damage can occur simply by screwing a bolt into an existing hole is not at all obvious to the user. If you use the mount in any way other than in the original system, it is extraordinarily easy for this kind of error to occur.

Bottom line, Celestron is not technically liable for the damage that occurred. But they do share the responsibility by creating a poor design that allows this kind of damage to occur far too easily.

Just my 2 cents.

2 yr warranty on the NexStar mount, but I don't know if that cover damage caused by the consumer.

Good Luck
