"Grab It", that's all you need to do.
AS Dave posted initially opening a Thor MK II is not insurmountable. In fact, its not hard at all to do.
This purposely ruined set screw and the absence of supportive information on the Thor products seems the rule rather than the exception, as Ive found from several others they too have this gnarled screw instance with their Thor components. Go ahead
peel back that sticker and see for yourself.
. There is a solution!
A small innocuous device called a Grab it and a good slow speed hand held bi-direction drill, surely does the trick in no fuss no muss, and virtually, no time. Inserting the Grab its cutting edge into the screw and using the reverse feature of a drill, it will cut a conical shaped hole well into the set screw. You dont have to go far either. In fact the set screw began to back itself out during the cutting portion of the extraction process.
The Grab it bits come in varying sizes too. A set of four can be bought online for $20 + shipping. I got mine at Lowes home improvement center.
Slipping out the tiny Grab it bit from the drill, turning it around, and re-inserting it back into the drill, you now have the extractor end at the ready. Insert it into the just cut cone and slowly apply some reverse torque from the drill motor. Violin! That once enigmatic conundrum of a fastener should no longer be an issue!
On some models the feet also need to be removed. Mine did. A rag of sorts and a pair of very strong hands, or channel locks will suffice there. However, on some the studs within the feet will thereafter need removal too. On mine the studs were more attached to the feet than to the chassis so turning out/off the Black Diamond Racing Cone footers was good enough. Youll note if you have to do this by how the feet are apportioned over the base plate, or simply on it, as removal will needs be done IF they cover the outer perimeter of the plate and body of the unit too by their own girth.
These Thor units, were singular blocks of aluminum at one time, and then whittled out to form a more or less one piece concern. Consequently, the base plate is quite tightly fitted to the circumference of the units body. Inserting a small screw driver into each of the holes and gently prying up a bit here and a bit there will relieve the bound plate and access is then granted!.
Youll have to dig further down from here on your own. I went no further as my issue was then at hand. I will say theres scant little in there thats visible right away, and more layers need to be peeled to really get into the workings of the unit. I had no such desires.
It might well have been that honesty thingy I spoke of earlier. It may have also been, that Lets leave well enough alone too. Im a big fan of the latter option generally speaking.
I simply needed a very minor technical task to be done. I asked several experienced, audio designers, and technicians, and was either refused flatly, delayed with their answer for weeks, or found the price tag for the exercise inordinate. The latter, IF I agreed to send it off, was to be done by those who had no working knowledge of Thor equipment. Ill not name then here.
Only one person offered to accommodate me with my issue but even he couldnt get to it for a fair amount of time. I was grateful for his intervention and offer of assistance, yet felt if at all possible to avoid shipping the unit.
So I waited and wondered and worried and pondered
and then hit the uh
Screw it, switch and began a thread inquiring about a step by step opening procedure
. And one finally came along.
But with such great fear in place, I put off doing it for an extremely long time anyhow.
Thanks much Emoonie for the help. And thanks also to Grab It.
The remote aspect of the MK II is now working just fine BTW.
Many times, things that seem very technical are not and a quick look see might just be the ticket to remedying the situation.
Thanks again to all those who have been of help to me, and I hope this is of help to another. If nothing else, those Grab it bits are the real deal and mighty handy things to have around!
