Hi,

Very very newbie and wierd situation. I bought the Orion XT 6 few
months back. If someone has had experience assembling it, then please
read on and help me.
The base has 2 plates which go on top of each other, held together
using a nut-bolt. I am not able to put these together. The nut has a
think plastic ring on the inside, so I cannot tighten the bolt. Are
there any tricks? Was I suppose to get rid of the plastic ring? It did
not say so in the instructions. Maybe I am just not using the right
tools and enough force.


I assume you have read the instructions several times.

The nut with a thin plastic ring inside is a nylon lock nut. As you tighten
the nut onto the bolt, the threads on the bolt bite into the nylon inside
the nut (which is what you are referring to as a "thin plastic ring")
thereby locking the nut and bolt together. Now, the nylon does not really
lock the nut and bolt together, however, the nylon holds onto the bolt so
tightly that the nut will not work loose under normal usage of the scope.
When installing a nylon lock nut onto a bolt, you can thread the nut onto
the bolt 1/2 to 1 turn by hand but then you must use a wrench to overcome
the resistance of the bolt threads biting into the nylon inside the nut.

The two plates to which you refer are the top and bottom baseplates. As you
no doubt have figured out, there are three teflon "bumpers" that are
attached to the top of the bottom, or, ground, base plate. On the bottom of
the bottom/ground base plate, you install three plastic feet.

The top baseplate has a hole in the center. In the parts bag is a nylon
bushing that fits into that hole -- the bushing should be pushed into the
center hole so it is flush with the top and bottom of the top baseplate.

To install the nylon locknut onto the bolt you must use TWO Crescent
wrenches, or, two pair of pliers, or, two tools of some kind because it does
require a bit of effort to thread the nylon lock nut onto the bolt.

If you don't have the instruction book, print this one:
http://www.company7.com/library/orion/Inst_skyquest6_8.pdf

The bottom (ground) baseplate has a T-nut already installed through its
center. Thread the 3/8-inch bolt up through that nut with the head of the
bolt on the bottom of the ground baseplate -- that's the side with the feet
on it. The threads of the bolt should be on the same side of the ground
baseplate as the teflon bumpers (these are the white pieces of plastic
stapled onto the ground baseplate).

You should already have assembled the sides of the mount to the top
baseplate.

Make certain the nylon bushing is inserted into the hole in the center of
the top baseplate.

With the ground baseplate sitting on the floor and the bolt sticking up
through the T-nut, set the upper assembly onto the bottom assembly -- the
bolt coming up through the ground baseplate will come up through the nylon
bushing in the center of the top baseplate.

Now -- and this will require three or four arms and you may want some
help -- get a wrench or pliers in each hand. Stand the whole thing on edge
so you can get a wrench or pliers onto the head of the bolt -- which is
protruding from the bottom of the ground baseplate. Put the single flat
washer down on the bolt then start the nylon lock nut onto the end of the
bolt -- it should thread on about 1/2 to 1 turn. Now -- hold the head of
the bolt in one wrench and with the other wrench, grasp the nylon nut and
tighten it.

Keep tightening it until the bottom of the top baseplate just contacts the
white teflon bumpers.

Now -- set the base on its feet and try to turn the base assembly around and
around -- the nut that you just installed sets the tension between the two
parts of the baseplate. You want the nut loose enough so the top baseplate
rotates smoothly by sliding on the teflon bumpers but you want the nut tight
enough so the top assembly does not wobble.

Is yours an XT-6 or an XT-6 Intelliscope?
