Just a follow up on this, I actually tried my 497 / DS motor combo with my 14.8 volt 6.6 ah Li-Ion pack that I use for my Atlas EQ-G. The results were...
Yes it is possible. The LXD-75 motors will bolt right on. You will have to shorten the bolt for the RA motor by about 6mm. "My advice is always free and worth...
I've shipped some things south. IIRC Brazil taxes everything a 65% of declared value including the not very inexpensive shipping charges. If I were in SA I'd...
Hi Dick, Can't seem to get my head around this one. Say my ETX is happily tracking in alt-az and I wedge it up to Polar, does the speed of the motor have to...
... The speed of the -motor- changes...to a constant rate known as sidereal (that 15 deg/hour). ... Um... "Great Circle" is not the correct term. "Spherical...
Hello again I have done my homework on the mount itself. I need advice on how to drive it. I am sort of leaning toward the Mel Bartel system. But if I could...
It would seem that all you need is a stepper motor control circuit, unless you are planning goto. I've seen kits for under $20 to control steppers at various...
Hi folks, I wonder if anyone with an EQ3-2 mount can help. The insert where the balance weight bar screws in has come slightly loose on my mount - it rocks a...
Maybe wrap the threads with some plumber's tape? "My advice is always free and worth every penny!" -Christopher Erickson Network Design Engineer 5432 E....
Thanks, Chris, but the insert doesn't seem to be threaded, unless I'm not applying enough force to either tighten or unscrew it. I'm not referring to the...
Hmm - I'm obviously not making myself clear. Forget entirely about the weight bar threads - the play I'm experiencing has nothing to do with them. The EQ3-2...
I see that ring, maybe a steel insert into the DEC casting? Only about 10mm? that's not much thread. So, it's this part that is loose? Any way you can pry it...
The actual thread length is 15 mm or more - 5 mm outside plus the 10 that extends inside. I've been applying some force to it now, and it turns reluctantly...
I'm not familiar with that little mount, but I suppose there's no reason that part couldn't be threaded on the outside and screwed into place. Looking at the...
Hi Peter, As I already had my EQ3-2 partially disassembled, I've had a good look and the insert is definitely just screwed into the housing, with no sign of a...
Thanks, Rob, I wondered if perhaps there was a grub screw inserted from inside the assembly where the curve of the RA shaft housing almost meets the edge of...
There is a tiny grub screw that lock the insert you really have to look very carefully around the outside, it is very easy to miss, unfortunately I no longer...
Hi Peter, Don't take the spanner to it! It only took a little more disassembly to check, and you are right, there IS a little grub screw, right just there! ...
-If there is a grub/set screw that would sure explain his problems. I've seen as small as 3mm used, which is tiny. They take a 1.5mm allen wrench. I think...
Well, there you go. Right where I suspected it might be! And a b***er to get to. Presumably I need to unscrew the bearing retaining plate that sits above...
Hello again: I bought two gears of 29.6 mm and 35 teeth to the axis of the screw bolts. The fact is that once fixed engines in the saddle, the wheels do not...
Hi Peter, Yes - the retaining plate is locked by 3 grub screws which you loosen via the thumbscrew hole. Once these were loose, mine unscrewed fairly easily -...
Glad to see this disassembly problem solved, these things always interest me even if I don't have the piece of equipment in question. As far as dropping parts-...
... Yes, it does. I was assuming (for no good reason) that the Autostar used Horizonal coordinates and alt-az and Equatorial coordinates in Polar. thanks. Geo....
Sorry, I should have read ahead. That's an EQ-3 (CG-4). Knock off of the Vixen Polaris. I guess in the Eueropean market Synta sold it as the EQ3-2. Your photo...
