Hardin DSH8 problem

I know there are alot of people with Hardin DSHs in this group. I just got
the DSH8 (and I have a bit of experience with the Orion Starblast-which I
bought for myself (not my kids!) a few months ago, and when I saw the price
of the DSH8s I decided to upgrade) and I am having a problem with the base.
The bolt that holds the two round pieces at the bottom keeps coming lose.
The other night the whole thing dropped out as I was moving it, the piece
with the feet on it fell to the ground. I put it back together but I've
noticed that it comes lose even if I just give the thing a spin or two. Any
ideas on how to fix this? Anyone else have this problem?

Thanks

Is there enough room on the bolt behind the nut which keeps unscrewing to
place a second nut? Tighten them into each other and see if that helps.
Or, and maybe more simple, remove the guilty nut and pour some white glue
inside of it so that it coats the threads. Wait until the glue dries and
then thread the nut back on the bolt. You'll have to force it to get it
started but it should fit nice and tightly and hold once in position. Or,
if you know you will never have any need to remove the ground plate from the
bottom of the rocker box (that's the name of the two "round pieces" you
refer to), you could use some type of lock-tight product available from a
hardware store. I wouldn't recommend this option however, since it stops
you from being able to remove the nut or adjust the tension which it applies
to the assembly.

Hope this helps.

Get a nut with the nlyon insert to replace the one you have. It also
acts as a lockwasher. That should do the trick for you.

Another technique is to apply a drop of "Crazy Glue" on the threads once you
have gotten it properly adjusted. Put it right where the nut and threads meet.
It is a "poor man's " Loctite and works well but can be easily freed up if
need be.

Poor man's Loctite?! Isn't Loctite cheaper than crazy glue, or at
least pocket change for either one?

My advice is don't mess around with crazy glue. It can end up drying
and locking the bolt before you have a chance to tighten it. Do it
right. Use blue Loctite. You'll find it at any hardware or automotive
supply store. It will lock the nut in place and you can loosen it
later. Before you do that you might want to call Hardin and find out
what is wrong. It doesn't sound right.

What is wrong?
There is nothing wrong. It is exactly as it should be. It's a budget dobsonian.
They frequently require tweaking. That goes with the territory.

No. Something sounds wrong to me too. Call Hardin. This is not a problem on
mine.
