That’s a bad casting ....if it’s a new unit I’m sure the gang at explore scientific will do something about it .......

That happens occasionally with cast metal.  Give customer service a call and let them know.  They will take care of you.  Explore Scientific isn’t perfect, but they own their issues and take care of their customers.  It may never break, but given where it is, I don’t think I would wait until it does.

Yep, ES has your back.  Some of the best customer relations and service I’ve seen.

They replaced an entire EXOS2GT mount for me about a year and a half ago after a motor/gear issue.

Should you worry about it? A bit, but really the factory that cast it should worry about it more. I have a similar non-structural casing flaw in the interior of the EQ head - I found it only when I opened it up to tune it. Out of warranty and not critical.

But it speaks to poor quality control at the factory, although at the price point of the older EXOS-2s ($460 when I bought mine) it is hard to complain.

For the record (my firm used to make four axis turrets that had to operate in high g and vibration environments), castings are the weakest form of metal work even if there are no flaws. Machining from forged billets is the best but costs a lot more. After that, machining from extruded billets like Losmandy does, then machining from cast billets. Last place in strength is machining of cast shapes (not billets).

The forging and extrusion pressures (and heat) makes the metal stronger, which of course means machining is slow and there is more of it. Weakest are castings. Poor quality control makes it worse, of course.

It all comes down to economics, but things like this cost the companies in both replacement costs and reputation, so I sure ES will do right by you.

Hi, as a stopgap, could you fill the crack with araldite?
But I have never found a company that treats its users so well!
Cheers,

Thank you all for your comments!
 
@Ian Morison : Yes, I could use araldite but that means that the resale value (I am not thinking of this...) goes really down!
 
@Mark Christensen : You said it all!
 
@Mario : Yiassou Mario! :)
 
As all of you point out about the ES relations to their customers (that matches my information prior the purchase), I hope that there will be a solution. Despite some minor things that i don't like in this mount, I wish that it will stay with me for a long time. The carrying capacity, the low wheight and the sturdingess are really fits my stantards. As for tracking, I got 20'' exposure with just a basic polar alligment and Ithink it will be much more if I hit the proper polar precision.

I allready messaged the ES in Facebook and I am waiting for some responce. Phone is not really my thing, because I am not doing good in English verbally. 
It is really nice and helpfull the excisting of this group. 
Thank you all!
 
Clear skies!

No, youll be completely fine. and the casting will not degrade, and the bubble level is effected by the casting. i always use a torpedo level for better level accuracy. i hope this helps and please dont hesitant to email me at Tyler@...
