    Default tired ot carrying your Losmandy GM-8 out, piece by piece?



    I got tired of it, too, so I built a caster assembly that slides into
    the GM-8's legs, and now I can roll my telescope out and be observing
    in 30 seconds. It was such a good idea, and it works so well, I made
    up a small prototype run, and I am hoping to sell them. See
    http://www.claytoncramer.com/GM8%20Casters.pdf for pictures and
    description.

    Jim's Mobile Industries sells wheeley bars to do the same thing--but
    this is $40, instead of $179, and they add less than two pounds to your
    mount.

    Hi,
    I have a Vixen GP on wood legs, and the plastic/nylon leg tips "slip" on the
    garage floor, which causes flexure of the wood. I would think that your
    system induces the same problem on any smooth surface, and likely even on a
    rough (grass/dirt) surface. I've thought of your solution, but frankly,
    given the flexure problem, I didn't like the idea all that much in the end.

    A wheeled platform or "bars", aloows the legs to be sescured to the
    platform, much as they would be when set directly into the ground.

    Sorry for the negative outlook on your idea. Now, if you used locking
    wheels, or added a lower leg support to prevent flexure, that might be
    viable.

    As others have pointed out, the casters have brakes. In any case, I
    haven't had any problem with leg flex. The GM-8 tripod legs are pretty
    sturdy. In practice, even on mild slopes (five to ten degrees), I
    haven't had any need for the brakes. I'm not even sure it would be
    wise to use them on more severe slopes, depending on your center of
    gravity for the mount and OTA.

    I tried a system somewhat like this with my (now former) Orion Atlas and
    Meade 12" SCT. The only difference was that mine was like a platform with
    wheels and the Atlas legs fit into three areas on the platform. However, I
    was never able to work around a 9" drop I have from the house foundation to
    ground nor was I able to safely wheel it out to the yard location which
    involved traveling over soft ground for about 30'. On the first attempt
    going through the yard using a wide wheeled hand truck to pick up the
    platform, the whole thing spilled over, dented the Atlas and nearly wrecked
    the scope. So, I ended up selling the scope and mount and now happily use a
    C8 on CG-5. This is lighter by far than setting up the 12"/Atlas.

    Sorry, I know this is a bit OT from the original post, but just pointing out
    that sometimes we pay a big price for convenience and don't realize it until
    an accident has already happened.

    Good luck with your device. I'm sure with the smaller SCTs, it should work
    well and also as long as there aren't large dropoffs or excessive soft
    ground distances.

    Hey JW...
    Those are all valid points which I experienced as well with my rolling
    setup. It was good for the driveway, but not great for the terrain of the
    backyard. JMI offers larger wheels, but I'm convinced that this is still
    precarious for scopes on rougher terrain. (All of which the OP points out.)
    Too much vibration on the bumps, and wheels of any size can end up going too
    deep in the soft stuff.

    It sure is nice to have a wheeled setup under the right conditions though.
    No doubt about it. I had an Ultima 8 on wheels (about 65 lbs fully
    assembled), stored in a shed at the end of a paved driveway. It took just a
    few minutes to open the shed, roll the scope down the ramp onto the
    driveway, and get a rough polar alignment. I could be observing real fast,
    with no cooldown issues (especially a few hours after sunset). It went back
    in just as easily.

    I miss those days. Now I have a 4" F9 refractor on GP which can be hand
    carried fully assembled (very nice, and a great scope), and a big Dob (12.5"
    F4.8) with a handtruck. These are stored in the garage facing the front
    yard, and moved out to the backyard for use. Unfortunately, the garage isn't
    as "cold" as the shed because it is insulated and under the bedrooms, so the
    Dob takes longer to cool than I care to put into it at this point. In the
    warmer months it's no problem. But in these cold months, it's less trouble
    to just lift the GP with refractor, and walk it out to the backyard.

    The handtruck has pneumatic wheels and carries the dob without much problem,
    but it _can_ get to rocking side to side, if one isn't careful. I could
    certainly see a larger tripod mounted scope on a wood base getting away from
    you.

    Take care,
    Stephen Paul
