Re: G-11 Re-Lube
Brian,

I got a tube of Lube Gel from Radio Shack for $3 or $4. A 3 oz tube should last quite a long time. It claims Superior adhesion:stays where you put it, Non-toxic and Non corrosive, won't wash off,didperse, break down or turn rancid, does not attract dust or other contaminants, Impervious to salt and fresh water and a temperature range of -45 to +450 F. works extremely well from what I have seen so far and am looking forward to using the mount the first clear night I don't have to work the next day. Hope this helps. Brian Kennedy wrote:

GM8
Brian Kennedy
I have a GM8 and some questions.
1) I am reading alot about tearing down and relubing the GM11. Is this something I should consider doing to my GM8? If so, what is the best lube to do this with? 2) My mount came without the delron gear covers. Should I invest in them. Will they offer me that much more protection. Thanks. Clear Skies, Brian |

G-11 Re-Lube
Thanks to all who contributed to advise on relubing the G-11. With
Mark's and others advice, I decided to try this myself and did indeed find that all bearings on the RA & DEC were seized. The only problem I had was in the beginning of disassembly. My mount came with the Losmandy encoders installed and you must remove the shaft gear in order to disassemble the shafts. It is easy enough to do as a set screw holds the gear to a flat spot on the shaft. All the other instructions were complete and easy to follow. The only other advise I would add is paying special attention to reassembly of the clutches to make sure they are not to loose or tight. I found that if I tightened the clutches fairly tight before locking down the set screw worked best for me. Any who have not attempted this really should. The difference is tremendous and really should be listed under maintenance in the manuals. I expect to get much better guiding using my ST-8 just due to the lack of friction that relubing cured. Again, thanks for all the advise. Clear Skies, Steve |

Re: How much pounds?
Adair,
I have a CG-11 with same setup except a ST-8 and Van Slyke Slider. I have and additional 11 Lbs. and have no problem with balance, even room to add some additional equipment if I wanted. I would go with no less then 10 Lbs. Hope this helps. Regards, Steve Adair Fagundez wrote: [eGroups] new group!

How much pounds?
Adair Fagundez
¿ªÔÆÌåÓýHello to all:
At this moment I am buying a mount Losmandy G11 to
place in this mount one telescope OTA Celestron 11 " with NGFS focuser and a DRO
JMI, together with one camara CCD ST-9E and too the possibly place a Flip Mirror
Meade 647. The mount comes with 21 pounds of counterweight. My question is: How
much pounds I am going to need to support all the previous equipment?
?

Re: G-11 Pwr Cable Connector
Sean Houghton
My power cable broke when I tripped on the cable and the wires came out of
the cigarette adapter.After having to do some soldering I just tied a small knot in the cord right before the wires exit the cigarette plug. This way if you kick the wires they pull on the knot, not the solder connection. Just a tip. Sean Houghton shought1@... San Diego, Ca |

that Scott reads this occasionally :-) I absolutely love my G11. Fabulous piece of equipement. Built like a rock, and worth every penny. The ONLY cheap bit on the whole thing is the power cable. I learned this after accidentally stepping on it one evening and watching the plug break, ending early a productive evening of shooting. My solution was to buy a pack of the little plugs intended for universal power supplies. One of them was the right size, and I was able to build a corresponding socket for it. Now if I step on the cable again, the little end piece will simply come unplugged. It would be a good upgrade to include with the scope.

Re: JMI NGC MAX complete install kit for G11
the only encoders to get are the ones from Losmandy, other encoders interfere
with the clutch operation..you can use any computer you like. Get the delrin encoder covers and route the cables neatly with clips etc.. You know, the G11 has nice mechanical settling circles.. "Glenn Smith" <gnsmithmd@...> wrote: Herm Astropics |

Any of the Tangent boxes will work but as far as the encoders are concerned the Losmandy encoder kit is the best for the mount. If you don't have the delrin gear covers, get them also. Don ----- Original Message -----

JMI NGC MAX complete install kit for G11
Glenn Smith
I am the new owner of a G11 (in fact, it still hasn't been unboxed
having just arrived). I have never even seen a G11, but I got one off astromart for a good price. At any rate somebody else found out that I had just purchased a G11 and recommended me getting the JMI NGC MAX complete install kit for G11. Does anybody have any experience with this? Is it worth getting if I can get a new one at a lower price than is advertised new on the net? Would it be better to get something else? Glenn |

DSC coiled cable
This G11 addition looks great and works well.
I bought a standard, 12' black good quality coiled phone cable and cut it into three pieces. One about half the length and one about 5" long (coiled size) and put the remainder in the spare parts box. The longer is for the Dec encoder since it moves the most. One end of each fits nicely into a RJ-45 connector side-by-side (8 contacts) and the other ends each go to a RJ-14 connector (6 contacts). You will need to check your current cable to see which one goes to which side of the RJ-45 and the direction of the RJ-14. You will need to straighten out the ends that were in the middle of the coil a bit (bend opposite direction by hand and hold for a while). This solves two problems, first the coiled cables don't get in the way. Second, the shorter cable prevents you from plugging the cables into the wrong encoder (but I sure that never happened to you). If you know anyone who does computer networking that will probably have the crimper and the ends. (or about $35 from Radio Shack for a combo crimper + plastic RJ-XX ends) Good luck. PS: Does anyone know of a source of 6 conductor black COILED cable for making spare motor cables? |

The Radio Shack model uses a slightly larger plug (5.5mm I think), but it works fine - I picked up one for a spare and tested it. These are fuse protected in the part that plugs into the battery so pick up a pack of spare fuses, just in case. It's in the $5-6 range. |

Yes. That's why I went back to the Allen-key bolts.

Slight wobble between G11 head and tripod pier
I seem to have a slight bit of slop between the G11 head and the
tripod pier. I'm using the TKS (no-tool tripod knobs) as tight as I can hand crank them. This is only noticable when there is weight on the unit (C11 & counter weights). The shift is about a 1/8" at worst. The knobs seem to shift a little in the enlongated pier slots. A shim between the pier and head would pull the knobs to the top of the slot and stop the slop as would accurately set round holes (Not a slam, just an obervation) Has anyone else noticed this? |

Re: Worm drives
Fred Park
Hi there,
I use a feeler guage and gradually increase space until the worm is free to turn the wheel gear with a little backlash. In RA a little backlash is OK since we only drive in one direction. Adjust balance so the motor drives against a slight load. Make sure the clearence is proper for the full turn of the wheel. And the latest on lubrication is to use Slick 50 as recommended by Steve Losmandy.

I am planning to build an `observatory'; four walls and a deck, noIt will hold up real well, there is nothing in the mount that will corrode. Since you plan on a permanent setup you may consider just buying the head, no tripod..and setting up a pier. Also, you would not need the polar scope. A Dessert Storm cover would work well, also an upside down trash can..try to keep a 25w light bulb on at all times inside the cover..this will keep the mount warm and prevent condensation as the metal cools at night. You could even make a rigid cover out of Sonotube and some plywood. Why not put a roll-on roof on the observatory?, very convenient as you can leave the ota mounted too. Herm Astropics |
