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.

Well I am not sure what your problem is.

Hopefully some one can help.

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.

Greyhaven can talk you thru it I am sure.
