I've just finished mine,  although i had a real headache with it at first i managed to get it all back together again.

Only one thing i can say that may help others,  It helped me......     Is that the tweasers that are supplied with the kit are a bit pointless as i couldn't grip the belt properly.   What i used was a set  fishing disgorger / pliers,   These can be clipped tight meaning that the belt won't slip out whilst doing this fiddly bit.

Having chatted with a few people now, one thing I would say is a major contribution factor for an "easier" installation is whether or not you have taken the mount apart in the past.  The knowledge acquired during that time is usually invaluable during this mod fit. If you have never stripped down an EQ mount, it would be beneficial to be able to talk to someone who has.

There have been a few instances where a bolt shears or a stud head is "rounded" due to it becoming stuck, which then has typically required them to be drilled out. For a sheared bolt, you don't really have a choice, but when the socket has been "rounded" it may be possible to use a non-metric hex wrench which will be slightly larger that the nearest metric equivalent. Also those "star" head wrenches, which have been used on various computer equipment, are great for gripping a rounded-out hex-headed bolt or stud (see attached photo)

There are kits out there for removing stripped bolts/screws :
  • Machine Mart have this
I have used both with varying degrees of success.

Finally if a stud or bolt is to be drilled out, it is probably best to acquire a re-enforced insert or "helicoil" as they can be known as... I will leave it to members here to give their recommendations for that.

To give yourself the best chance spray all the threaded components with penetrating lubricant a couple days before you start the job (gives it chance to to get in between the threads). If you can get a straight-shafted bit (often to be found in those multi-bit screwdriver kits) onto the bolts or Allen setscrews then use it together with a small hammer and give it a whack to break any corrosion seal that may have formed. Preparation is the key - easier to do this than try to repair the problem screw later...  Another trick with small socket setscrews is to poke a hot soldering iron into the hole for a couple of minutes, that will heat it quickly and aid breaking a corrosion seal.

So far so good,   

My guiding graph with a OAG has never looked so good. I'm happy ATM  :D :D :D    Also doing a real SGP sequence, I think I have sorted the focusing,  plate solving worked but when set up for the real test it didn't want to play ball.  But the guiding graph makes up for a hiccup.
